Who Turned Out the Light?

Who Turned Out the Light?

With the days growing ever shorter, I find myself thinking about light and how we tend to take for granted the hard work that plants do, harnessing the energy from the sun. Photosynthesis is the beginning of most food chains on earth, the exceptions being bacteria (Archaea) that can obtain energy from inorganic chemicals like sulphur and ammonia. But since we don’t eat bacterial ooze for breakfast, this process remains relatively unimportant to humans. Photosynthesis is what gives us life!

Looking down at three small plants growing from the ground. Each has several green leaves, and a single white four-petaled flower.

Photosynthesis is a process where plants, and plant-like aquatic creatures such as phytoplankton, use energy from the sun (photons) to combine water (H2O) with carbon dioxide (CO2) from the air, to make sugar (C6H12O6). Oxygen (O2) is a “waste” product of photosynthesis. This reaction takes place in special green-coloured plant cells called chloroplasts. Plants and phytoplankton use the sugar they make to grow and reproduce themselves.

Animals and fungi are incapable of photosynthesizing; they have to “eat” plants to stay alive. Even meat-eaters (i.e. carnivores) are ultimately dependent on plants for their survival, because they eat animals that eat plants or phytoplankton. Further, the oxygen that plants produce is also required by animals to breathe. Thus, we depend on plants for our very lives.

Some northern plants are “evergreen”, which lets them begin photosynthesizing as soon as the ground thaws in spring. In contrast, deciduous plants have to grow a whole new set of leaves before they can begin photosynthesizing again. As there is almost continual sunlight over the summer months in the far north, tundra plants can photosynthesize almost non-stop during this time. They must quickly produce enough sugar over the short summer to stay alive, in a dormant state, over the long, dark winter.

One way that plants can increase the amount of light they receive is by slowly moving in response to the direction of the sun (i.e. heliotropism). Like tiny solar ovens, species such as Entire-leaved Mountain Avens (Dryas integrifolia), move their flowers each day so that they continually face the sun. As a result, the flower temperature is several degrees warmer than that of the air. This improves seed production, in part, because pollinating insects are more likely to visit warmer flowers. In other plant species (e.g. sunflowers or Helianthus) it is the leaves that rotate to be perpendicular to the sun, increasing the amount of light for photosynthesis.

Many ancient human societies in the northern hemisphere held religious gatherings or celebrations around the winter solstice (typically Dec. 21 or 22) because even though they knew many cold days were still ahead, the amount of sunlight would begin to increase again. Evergreen plants, like spruces, pines, mistletoes and holly, were sometimes part of these events, because they are the plants that refuse to wither when the light begins to fade.

William Beal, Renaissance Man of the North 

Black and white studio portrait of a man in a dark suit and tie in front of a neutral draping backdrop.

This last summer the Museum installed a new permanent exhibit about William Beal in our Parklands Gallery. Beal was a settler from Minneapolis who arrived in the Swan River Valley north of Duck Mountain in 1906, and homesteaded in the Big Woody district.

William Sylvester Alpheus Beal (1874-1968) is best known now as a photographer, and left behind dozens of high quality images of his fellow settlers in the region. But Beal was much more than a photographer – he was the “Renaissance Man” of Swan River, a true intellectual. Besides having his own photo studio, he was a professional steam engineer and oversaw engines at various logging operations.

 

Image: William Beal, self-portrait, Swan River, Manitoba, circa 1918.

 

 

He was also an amateur astronomer and constructed his own telescope; he formed a literary and theatrical society, and organized musical recitals; he organized and served on the local school board for 37 years; he was an assistant to the local doctor, providing a type of vaccine injection to locals during the 1918 Influenza pandemic; he was an electrician and fine carpenter; and he was renowned for owning a vast library. Evidently the only thing that didn’t interest him was farming, but he nevertheless cleared land, harvested crops, and received his full homestead grant.

Black Settlers in Manitoba

The racism William Beal experienced in the United States denied him his chance of becoming a medical doctor. Though he formed close friendships in the Big Woody district, he was the only Black man in the area, and experienced racism there as well. 

In the early 1900s the Canadian government actively prevented immigration of Black people to Canada, through misinformation campaigns, bribery of officials, and arbitrary requirements not asked of white immigrants. In 1911, 200 Black farmers from Oklahoma were finally able to enter Manitoba at Emerson, after a rigorous and delayed inspection. It’s not known what hurdles Beal faced when entering Manitoba back in 1906, but after he settled in Big Woody district, he was there to stay, and contributed so much to the local community. He passed away in 1968 at the age of 94.

The Enduring Diorama – Museum Pronghorns Still Going Strong After 50+ Years

The Museum opened our newly renovated Prairies Gallery just last spring with spectacular new exhibits on the intriguing and engaging natural and human history of southern Manitoba. The addition of ground squirrels and their burrows, a riverbank bison bone bed, a homesteader stone house, an old school room, and hundreds of new specimens and artifacts, along with life-sized animations, prairie soundscapes, and feature videos provide exciting immersive experiences.

But some things from the old ‘Grasslands Gallery’ didn’t need changing, only a facelift. The pronghorn diorama at the gallery’s entrance remains as awesome and as valuable an educational tool as it did when it opened over 50 years ago in the summer of 1970, when it caught the eye of our first official visitors, Prince Philip and Queen Elizabeth:

A newspaper clipping reading,

The Prince asked a good question – pronghorn were frequently seen in the province prior to 1880, but are now only rare visitors wandering from North Dakota or perhaps Saskatchewan. But this is just one of hundreds of good questions that the diorama can elicit and help answer.

The diorama was designed, its backdrop painted, and installation overseen by renowned Manitoba artist Clarence Tillenius. He began planning in August 1968 and completed it, along with the bison diorama (much longer in production, from 1963), in June of 1970. As has remained the tradition for our dioramas to ensure authenticity, Tillenius visited the site that is portrayed, driving with other Museum personnel north of the U.S. border “to a point south of Waskada from where I [Tillenius] painted a study of the west end of the Turtle Mountains [sic] which appear in the background landscape.” (From a June 12 1970 letter to Dr. F.A.L. Matheson, then-president of the Museum.)

A rough handwritten plan for the Pronghorn antelope diorama. On the left are some notes about how many animals to include, what season to set the diorama in, and what size it should be. On the right a small sketch of the diorama from above with four animals. The note is dated August 9, 1968.

A rough plan for the diorama as envisaged by Tillenius. The basic size and shape was maintained, but only two actual pronghorn, a male and female, were in the final exhibit with a herd painted into the backdrop.

The pronghorn diorama effectively introduces the new Prairies Gallery much the way it introduced the original Grasslands Gallery, except for the new vibrant panels and its reinterpretation in a modern context. But it still shows the southwestern part of the Manitoba as it was before colonization, providing an opportunity to think about the transformation of our prairies over the last 250 years. The pronghorn diorama might be the closest some of our visitors ever get to experiencing original prairie in three dimensions. They can wonder at its expanse, its wildlife, and ponder its future. And it will do so for the next 50 years, or more we hope, perhaps inspiring the next generation of nature-conscious Manitobans to save our last vestiges of wild grasslands and their inhabitants.

Enduring – according to the dictionary – means having a validity that does not change or diminish. The pronghorn diorama, and the Museum’s many other signature life-size dioramas (bison, polar bear, caribou, moose, wolf den, elk, bat cave, snake den, Delta Marsh, Winnipeg 1919, and Nonsuch) are prime examples of enduring, undiminished wonder, exploration, and inspiration.

Come see for yourself!

Resilience During the Great Depression

In the 1930s the people of the Canadian prairies experienced both an economic collapse and an environmental disaster. The stock market crash came first, in 1929, followed by a decade of drought in central North America. Wheat prices plummeted, and many crops were totally destroyed. Two thirds of prairie residents would eventually require “public relief” to survive.

With farms failing or deserted, and local economies in crisis, there was simply no cash to be had. How did these victims of disaster provide for their families? Many abandoned their livelihoods or farms and moved across the country, looking for work. Others took what aid they could find, including government work projects or vouchers for food and coal. Everyone became resilient and creative in their day to day lives.

The exhibit about the Depression in our new Prairies Gallery showcases artifacts of thriftiness and determination in desperate times.

Hot to Trot: Plant Hunting in a Drought

Doing biological field work always comes with challenges. Since I began working at the Museum in 2003, the summers have been relatively wet. As a result, I’ve had to deal with muddy roads, many, many biting insects thirsty for my blood, and bootfuls of water obtained while exploring flooded wetlands. This year though, the roads were good, the biting insects non-existent, and many wetlands were so dry that I could walk right into the middle of them-no rubber boots required! In contrast, my main concern this year was possibly getting heat stroke!

Looking out over a lack and nearby brush and wetland.

As part of my research for a new book on Manitoba’s flora, I’ve been trying to track down populations of historically-collected plants (some of which haven’t been collected for over 100 years) to see if they still grow here. Fortunately, this year, all of the sites I needed to visit were close to major bodies of water: Lake of the Woods, Lakes Winnipeg and Manitoba, and Lac du Bonnet. As a result, I was able to go for a quick swim in the nearby body of water to cool off after a long day of hiking. Swimming is especially satisfying when you have been wearing long pants, wool socks and hiking boots in 30°C+ temperatures all day. Field work this year also involved drinking copious amounts of water (which were nearly completely sweated out given that I didn’t have to go to the bathroom all day!), lots of SPF 50 sunscreen, taking breaks under the shade of a tree, and wearing a cooling, water-soaked bandana around my neck.

 

This wetland near Lac du Bonnet that I visited was almost completely dry.

Looking down a emerging sandbar toward a section of wooded land. Water flows either side of the sand bar.

Dipping my hot feet in the cool lake water at Elk Island Provincial Park felt amazing!

Looking down at a wispy green plant growing in sandy ground by low water/.

I also got lucky with my field work, finding a new rare plant population and a new plant species for the province. The first rare plant species I discovered was Hairy Bugseed (Corispermum villosum). This species is currently ranked S1 (critically imperilled) in Manitoba because there are only three populations known in the province. I discovered a small population at St. Ambroise Beach Provincial Park on Lake Manitoba. Additionally, the population of this species that occurs out at Lake Winnipeg was found to be more extensive, extending all the way to Elk Island Provincial Park.

 

A new population of Hairy Bugseed was discovered at St. Ambroise Beach Provincial Park.

Out at Lake of the Woods, there are several plant species that reach the northeastern edge of their range. One is the lovely Small Purple Fringed-orchid (Platanthera psycodes). It was suspected to occur in Manitoba, but no one had actually collected a specimen until 1984. As I had never seen it before, I was thrilled to find and photograph the two plants in flower at the site.

Not far from the orchid, I saw another plant that I was on the lookout for: White Avens (Geum canadense). Although this species is relatively common in Ontario, Quebec, New Brunswick and Nova Scotia, it has apparently never been collected in Manitoba before. I carefully removed part of the stem only (not the root) to make an herbarium specimen, after verifying that there were more than ten additional plants in the vicinity.

The Small Purple Fringed Orchid was an exciting, and beautiful find!

I collected the first ever specimen of White Avens in Manitoba this summer.

Finding these new, rare plant populations made the hot, July temperatures much easier to handle. The specimens collected will be carefully preserved in perpetuity at the Museum to document these plant populations for conservation purposes, and for future researchers to study.

The Importance of Being a Flower

Like many of you, I enjoy walking through my neighbourhood and smelling the sweet fragrances of the summer flowers. Unfortunately, like many things, flowers are ephemeral. When I see a flower, I am always reminded of the Robert Herrick poem urging us to:

“Gather ye rosebuds while ye may,
Old Time is still a-flying;
And this same flower that smiles today,
Tomorrow will be dying.”

 

Since most wildflower field guides only feature pictures of the flowers and leaves, it is difficult, and sometimes impossible, to identify plants in the fruiting stage. So, to help our visitors identify the fruits of some of the most common plants in our province, a new case in the Museum’s foyer, called “The Importance of Being a Flower” recently opened. This case features 14 species of fruits juxtaposed with a photograph of the flower. Although fruits and seeds are not always attractive to look at, they are just as important as the flower, perhaps even more so, for they carry the DNA of another generation of plants in them. Flowers may only last a day, but seeds can last for decades or even centuries.  The oldest seed to ever germinate was a 2,000 year old date palm collected by archaeologists in the 1960’s from a fortress that had been build by Herod around 35BC and destroyed by Romans in 73AD (click here to read more)!

A new, temporary exhibit on seeds is in the Museum’s foyer.

In severe drought years, like the one we are experiencing this year, some summer- and autumn-blooming perennial plants will not produce flowers or seeds at all; they conserve scarce water resources by foregoing reproduction altogether.  Doing so increases the likelihood that the adult plants will survive.  Although most spring-blooming plants did produce flowers, they may produce fewer seeds to reduce water stress on the adult plant.

Museums and other institutions like gene banks and University herbaria, protect and preserve fruits, seeds and other storage tissues of economically important species, as well as wildflowers. You may have heard of one of these facilities, the so-called “doomsday vault”, formally known as the Svalbard Global Seed Vault. This Norwegian facility has ultra-cold storage freezers that keep the DNA in seeds from degrading rapidly, the way they would at ambient temperatures. However, that facility is our last line of defence; other collections are also needed to adequately protect plant genetic diversity, including the Plant Gene Resource of Canada in Saskatoon, (click here to learn more). Many of our most important crop species are stored in gene banks for use in breeding programs, or to use if natural disasters negatively affect crop fields or wild plant populations.

The Museum collection contains the fruits and seeds of many species.

Another important thing to remember is that plants are constantly evolving to adapt to new conditions. Therefore, it is important for botanical institutions to continue collecting new samples to capture this evolution. As well, seeds stored in the vaults must be periodically grown, to allow them to generate newer, fresher seeds for preservation.

In addition to the foyer case, several of the Museum’s old seed collections are on display towards the end of the brand new, Prairies Gallery. Wildflower seeds collected in the 1920’s by naturalist Norman Criddle, are in the Breaking the Land case, and a collection of crop seeds made by a Junior Seed Growers Club in the 1930’s, are in a case on the Great Depression.

Some of the seeds in the Museum’s collection are so small that I marvel at the fact that all the information needed to build a new plant is actually inside. Life is truly amazing! Now, get out there and carpe diem!

How to Polish a Jellyfish

By Debbie Thompson, past Diorama and Collections Specialist 

More than 440 million years ago, during the Ordovician Period, northern Manitoba was at the edge of a sea near the equator. Among the many invertebrates that swam and lived in the salty waters were jellyfish. Their fossilized remains are the focus of ongoing research at the Museum.

After years of collecting, specific specimens were chosen to undergo a process called thin sectioning. This process creates ultra-thin slices of rock and fossil, supported by epoxy and glass slides. They are thin enough to allow light to pass through, revealing details about internal structures, which can then be studied using a microscope.

The fossils selected for this process can range in size from one to four centimeters in diameter. Every block is trimmed using a rock saw, so that the block will fit onto a glass slide.  The fossil surface then needs to be polished smooth and to an accurate scale in millimeters written on two sides of the block.

WIth a purple arrow pointing to it, on the lower right, is a glass slide, and with a yellow arrow pointing to it, on the upper right, is a recycled yogurt container.

The red arrow points to the fossil block, note the scale (numbers written on sides of block).  The foil is peeled back to reveal the polished fossil surface. The purple arrow points to the glass slide, which has been polished so that epoxy glue will stick to it. The yellow arrow points to a container that is warming one part of a two-part epoxy. The hot plate heats up these components to aid in the even flow and setting of the epoxy. Image: © Manitoba Museum

Normally, a whole day will be spent just gluing the specimens onto the slides.  To help pass the time, it helps to listen to country music while doing this (although the Curator would strongly disagree with my choice of music). Image: © Manitoba Museum

A work station set up with various tools and equipment including earplugs, ear muffs, safety glasses, blue rubber gloves, a sponge, and a high-quality face mask.

Before starting the rock-cutting saw, the radio is turned off, much to the Curator’s delight! The thin section machine is noisy, creating the need for ear plugs and heavy-duty earmuffs.  Safety glasses are a must, guarding against stone chips.  The gloves protect the hands from being water logged for extended periods of time.  A mask is needed to prevent breathing in the water spray laden with sediment, as the water is recycled and gradually becomes dirtier the more it’s used.  The sponge is used to clean up the sludge that accumulates in the tray.

The fossil has been cut and partially polished so thin that light begins to pass through it. It is nearly thin enough for microscopic study. The final hand polishing will be done by the Curator, using a slurry of fine grit on a glass plate. The slide is then placed in a protective envelope. In this example, the fossil is near the top left corner of the slide. Some of the internal features are a dark reddish colour, due to the presence of iron oxide. The faint pale outline is the edge of the jellyfish’s bell. Image: © Manitoba Museum

A fossil block laid on a metallic surface. The top fo the block is smooth from a fresh cut. On the short side is written a size scale, showing 5-25 mm in 5 mm increments.

The newly exposed cut surface is re-polished, and the whole process is repeated. Depending on how deep into the rock it goes, each block can yield 4 to 6 thin sections, creating thin slices that are just two millimetres apart. If a new fossil appears, we keep making thin sections. If the fossil disappears, one more slide is made to confirm that we have reached the end of sectioning for that specimen.

Light passes through a finished thin section, revealing such intricate details as the rust coloured internal canals (due to the presence of iron oxide), and the margin of the bell with faint traces of its tentacles around the outer edges. Ruler is in millimetres. Image: © Manitoba Museum

After sectioning, the slide is scanned on a photographic flatbed scanner. A computer program then digitally assembles the thin section photos for each jellyfish to generate a 3-D image of the body, including internal structures and in some cases, tentacles.

Perseids Meteor Shower: 2021 Edition

August brings the Perseids meteor shower, an annual event that gets many people looking skyward. In recent years, social media has been hyping (and sometimes overhyping) celestial events, since they tend to generate a lot of interest (and thus “clicks”, “likes”, and “shares”), so it can be hard to know what you can actually expect to see. Here is the Manitoba Museum Planetarium’s guide to the 2021 Perseids meteor shower.

Perseids Meteor Shower 2021

Start of activity: July 17

Peak activity: early morning of August 12

Peak rate: 50-75 meteors per hour from a dark sky

Lasts until: August 24

A photograph of several meteors shooting past in the night sky as the last bits of sunset fade away near the horizon.

What’s Happening?

A meteor is the formal name for a “shooting star” or “falling star” – it’s a streak of light that flashes across the night sky. They happen when a tiny piece of dust or grain of sand from space crashes into the earth’s atmosphere at thousands of kilometers an hour. The speed of the dust particle gets turned into heat and light energy, and creates the visible flash we see. The piece of dust is totally vaporized while still high up in the atmosphere dozens of kilometers above Earth’s surface.

This actually happens all the time, but most of us don’t notice. If you went out on a dark, moonless night you’d probably see a half-dozen metros per hour if you watched the sky continuously. But they only appear for a second and they’re gone – so look down at the wrong time and you’ll miss them.

The source of this dust is perhaps surprising – it’s leftover material from the formation of the planets. There’s dust spread throughout the solar system, each piece in orbit around the sun like a tiny planet. The earth as it orbits the sun sweeps up some of this dust, and each one becomes a meteor.

Several times a year, though, the earth goes through an extra-thick area of dust – like a cosmic dust bunny. These dust bunnies are left behind by comets – “dirty snowballs” a few kilometers across that orbit the sun in oval-shaped orbits. When comets get close to the sun, the snow melts and leaves the dust behind in a trail. If that trail happens to cross the orbit of the earth, we will see a meteor shower every year on that date.

The Perseids

The Perseids meteor shower is probably the best-known meteor shower (although it’s not the best one of the year) because it happens during summer vacation time for the northern hemisphere. Its peak is around August 12th each year, although the date varies by a day or so. The Perseids are dust left behind by Comet Swift-Tuttle, which loops around the sun every 133 years or so. The meteor shower is named after the constellation that the meteors seem to come from – the constellation Perseus.

How and When to Look

The best way to see meteors is to get outside the lights of the city. Some of the meteors will be faint, and so you will miss them if the sky is too bright from nearby streetlights, houses, or other sources of illumination. A park or parking lot outside the city is a good place to head. This year, the light from the Moon will not interfere either because the moon will set in early evening, so this is probably one of the better years to see the Perseids.

Meteor showers are the ultimate in low-tech observing. Take a blanket or reclining lawn chair along, and set up with your feet pointed away from any nearby lights or light pollution. (For southern Manitobans, this generally means putting your back to Winnipeg’s lights.) You don’t need binoculars or a telescope – you want to be able to see as much sky at once as you can, since the meteors can appear anywhere in the sky. A telescope would just narrow your view too much.

Turn off your phone – the light from a mobile device will ruin your eyes’ ability to see faint stars and meteors. Even a quick glance will make it hard to see for a few minutes, so resist the inclination to check the web. Spend the time with the stars instead.

As for when the look – it depends on what you want to see. If you go out before midnight, you will see only a few meteors, but the ones you do see will probably be big bright ones. If you want to see lots of meteors, you want to watch from about 2am to dawn on the morning of the 12th. In the run-up before dawn, your part of the earth is heading straight into the trail of dust, and you’ll see the most meteors.

This is why some people have been disappointed by meteors showers (in addition to the social media hype). Meteor showers have a slow fade-in period of a few weeks, then a peak that might only last a few hours, followed by a slow fade-out. On the night before or after the peak, meteor rates are often less than half of what the peak is, and the rate drops quickly as you get farther from the peak.

This year, the Perseids are definitely worth the drive out of town for the peak. I plan to be out from dark on the 11th until dawn on the 12th with our all-sky camera system to record what we can. Follow the Manitoba Museum on social media for updates and live broadcasts during the meteor shower (weather permitting).

While you’re out counting meteors, there are lots of other sights to see: constellations, planets, satellites, and the year’s best views of the Milky Way. Visit the planetarium in person to see Manitoba Skies, a live sky tour, to learn more (showtimes here). You can also check the Manitoba Museum’s Astronomy blog for Manitoba Skies posts about monthly night sky information.

Clear skies!

Treaty Number One Medals at the Manitoba Museum tell a First Nations Story 

By Maureen Matthews, Past Curator of Cultural Anthropology 

 

For the commemoration of the 150th Anniversary of Treaty Number One, three Treaty medals from the Manitoba Museum will be on display at Lower Fort Garry. Although these medals were used by Canada to acknowledge promises made by the Crown to First Nations people in Treaty negotiations, they also reveal a history of First Nations protocols, diplomacy, and political advocacy at a difficult time.[1] 

The gift of medals to honour mutual obligations in Manitoba began with the fur trade.  The first HBC Chief’s medal was created in 1776 by Thomas Hutchins, Hudson’s Bay Company (HBC) Chief Factor at Albany who found that among the Ininiwak who lived on the edge of Hudson’s Bay, there was an expectation that medals would be offered. Hutchins told the Governor of the company that “ … medals also are much esteemed amongst them if large, and if presented with ceremony when the Calimut [Calument or Pipe] is smoaked[sic], will be not only deemed a mark of distinction but perhaps be a means of binding the Leaders more securely in your Interest.” (quoted in Carter 2004). During and after the war of 1812, many First Nations leaders in Canada and the US were presented with medals featuring King George III in thanks for fighting with the British against the United States. By the time negotiations for the Numbered Treaties were initiated, medals were part of a 200 year long First Nations history of Treaty making and had been used to secure a range of mutual understandings, alliances, and friendships.

When we talk about Treaty Number One, the image which comes to mind is the famous handshake medal shown here, but in fact this is not the medal that was offered in August 1871 when Treaty Number One was finalized. If you look carefully, you will see that this medal is dated 1873.  

The Treaty Commissioners who arrived from Ottawa in 1871 to negotiate Treaty Number One seem to have underestimated the importance of the gift of medals as a gesture of good faith and reassurance to First Nations leaders because the first medal they presented to the chiefs in 1871 was a smallish silver medal with an oak leaf wreath on one side and a standard image of the young Queen Victoria on the other. The medal was chosen from the existing stock of generic medals made by J.S. & A.B. Wyon of London, England. It was small, thin, and made no overt reference to the momentous nature of the Treaties it was meant to signify. The Chiefs who participated in the negotiations that year thought it looked a little too much like a prize at an agricultural fair, and after seven days of negotiations and months of preparation on the part of First Nations leaders, this non-descript Treaty medal seemed to the Chiefs to be an inadequate gesture. As an expression of intent, this generic medal must have worried the Chiefs because it left a feeling that Canada was not taking to heart the enormous implications of the Treaties.

The Treaty Commissioners, having registered the rebuff, returned to negotiations in 1872 with a much more dramatic medal. It was very large, 95 millimeters (almost 4 inches) in diameter, and was based on the medal struck to celebrate Canadian Confederation. The center circle has an image of Imperial Britannia as a Roman matron with a lion resting his chin on her lap and the four founding provinces, as Roman maidens, each hold a shovel, axe, paddle or scythe illustrating their province’s economic possibilities. Surrounding this Confederation image, the medal maker, a Canadian silversmith Robert Hendry of Montreal, added an 11-millimeter band which declared, on one side, “INDIANS OF THE NORTH WEST TERRITORIES,” and on the other – the side with the image of a slightly older Queen Victoria – “DOMINION OF CANADA / CHIEFS MEDAL 1872.” This medal was initially welcomed by the chiefs until it became apparent that it had been struck in copper and merely electroplated with a thin coat of silver. The Anishinaabemowin word for silver is zhooniyaawaabik, literally ‘money metal,’ and it matters if it is pure. When the silver began to peel and rub off, the Chiefs judged this medal a very shallow gesture on behalf of the Crown.

The largest medal; highly decorative, portaying a scene with Imperial Britannia, a lion, and Roman maidens; text around the edge of the medal reads, “Indians of the North West Territories / Juventas et Patrius Vigor / Canada Instaurata 1867”. 3. Final medal; the Treaty No. 1 handshake medal; a circular silver medal portraying a representitive of England shaking hands with a First Nations leader; they stand on grassy ground in front of tipis and the rising sun; text around the edge of the medal reads, “Indian Treaty No. 1 / 1873”.

By the summer of 1873, the chiefs were restive, most particularly because oral promises made at the time of the first signing were not being written down on the Treaty documents, but also in protest that the 1872 medal had been yet another inadequate signifier of the sincerity of Canada’s promises. So it was in the summer of 1873 that the now famous 99 per cent pure silver medal with the handshake was commissioned. Like the first medal, this one was made in London, England, by J.S. & A.B. Wyon. The front features a bust of Queen Victoria and the inscription “VICTORIA REGINA.” The inscription on the reverse side reads: “INDIAN TREATY N°. –  and the date 187- .” The spaces were deliberately left blank and were incised with the Treaty number and date at the moment of concluding each successive Treaty. The handshake medal was used until Queen Victoria’s death, by which time relationships had taken such a negative turn that a hollow bronze medal with Edward VII on the back was accepted with little comment.

The handshake medal has come to resonate powerfully with First Nations peoples for the promise it holds, for the idea that a respectful relationship with the Crown will be restored. But the handshake medal is still a product of the 1870s, designed in London by an engraver who had never been to Canada and had certainly never met a Treaty Chief.

The fully clothed figure on the left side of the medal, a representative of the Queen, resembles no one more than the Prince of Wales, later King George V, although the uniform is controversial. But with Queen Victoria on the back and someone who looks like the Prince on the front, the medal is a graphic confirmation that the Treaty relationship is between the Crown of England and First Nations. The bare-chested, feather-skirted Chief, on the other hand, is problematic. Photographs of Treaty events in 1873 show crowds of men dressed in suits and it is actually quite hard to pick out the Treaty Commissioner and his party unless they are up on a dias or have a chair to sit on, because everyone present is dressed the same. The chief on the medal does not seem to bear any relation to the First Nations leaders who made Treaty Number One. The adjacent photo is of Chief Gaagige Binesi, Forever Thunderbird, also known as William Mann Sr. who negotiated Treaty Number One on behalf of Sagkeeng First Nation. The large photo, taken and printed in the 1870s, shows Chief Gaagige Binesi wearing the original Treaty Number One Chief’s coat he received in 1871. Five generations of the Mann family looked after this photo. In 2012, 140 years after it had been taken, Ted Mann brought the photo to the Manitoba Museum asking that it be used to tell the story of his famous ancestor and his role in the making of Treaty Number One. The image actively foregrounds a strong, confident Treaty Chief and provides a corrective to colonial imagery that patronizingly romanticizes Indigenous peoples and undermines their authority.   

And where did this strange Indigenous imagery come from? It is probable that the engraver at Wyon in London was using as a model, an American Peace medal from the American Revolutionary War when George Washington was President. There were many iterations of this American medal over the years, but the feather skirt and strange feathers persist.

The handshake Treaty Medal is a part of First Nations Treaty history and the gesture of the tentative handshake suggesting equity alludes to a British way of making a promise. First Nations people have a long history of holding the Crown to account for these promises. And if the inescapable implication of the Treaty Chiefs is that First Nations participants in Treaty-making were “noble” but naïve, and probably incapable of understanding Treaties or their implications, the photo of Chief Forever Thunderbird provides a strong counter narrative to the racist image of primitive naiveté; the portrait shows that the chiefs negotiating the treaty were wise and thoughtful political figures. The handshake medals, as signifiers of the Treaty relationship, like the Treaties themselves, hold both the promise of sincere reciprocity and the dangers of racist condescension. 

[1] Others argue that the fact of the changes were made as the negotiations proceeded through each of the early numbered treaties – as new provisions for hunting rights, rights of occupation, and a medicine chest clause were added – is evidence that there was some significant degree of First Nations agency in the negotiations taking place. In an article looking at the change in view on Treaty No, 1, Hall cites the following historians: John Leonard Taylor (1975, 1979), Richard Price (1979), John Foster (1979), Hugh Dempsey (1978), and Chief John Snow (1977).

Remembering Private David Thomas of Peguis First Nation

In recognition and celebration of National Indigenous History Month, we’re featuring an artifact from Private David Thomas, a Peguis First Nation soldier who died in the First World War. An exhibit featuring his story and a handkerchief he had sent to his sister from Europe was on display in November 2020. Unfortunately we closed to the public that week because of a COVID-19 province wide lockdown, and no one was able to see the exhibit! We’re putting it up again in November, 2021, and then it will become part of the Parklands Gallery “Impact of War” permanent exhibit.

David Thomas was only 18 years old when he left his home at Peguis Reserve to fight in the Great War in Europe. He joined the 108th Battalion (Selkirk) in 1916, which was soon shipped out to England. A year later he was killed in the Battle of Passchendaele, in Belgium. Private Thomas died on October 26, 1917, the first day of the assault, possibly a victim of a poison gas attack. The 27th Battalion (City of Winnipeg), was finally able to capture the village of Passchendaele on November 6. Over 4,000 Canadians died and almost 12,000 were injured in two weeks of horrific fighting.

Private Thomas likely purchased this beautiful handkerchief in France. He sent it to his sister Mary Ann, who was living at Peguis Reserve. It is embroidered with a maple leaf and crown, and the words “Honour to Canada.” After learning of David’s death, she framed the handkerchief and it was displayed in Thomas family homes for over one hundred years. It was donated by the family to the Museum in 2020.

First Nations Soldiers

Over one-third of eligible First Nations men and women in Canada voluntarily enlisted during the First World War. More than 50 First Nations soldiers received recognition for bravery during combat. While there was a shared sense of camaraderie with non-Indigenous soldiers during the war, they returned, having been stripped of their Treaty rights, to a country that provided no compensation or support for First Nations veterans after the war.
