We're Back in the Rigging Again!

We’re Back in the Rigging Again!

By Kathy Nanowin, past Manager of Conservation

 

Well, after thirteen years or so, the Museum’s conservators are back climbing in the Nonsuch rigging, in order to check and clean the lines, sails and masts. This is a very exciting development for Collections and Conservation.

A bit of background information – amendments to Manitoba’s Workplace Safety and Health regulations in 2002 resulted in stricter requirements for workers climbing at heights. The Nonsuch therefore had to be provided with fall arrest lines, in order that workers could safely climb up in the rigging. The Manitoba Museum worked for the next several years to design, cost and install appropriate safety lines from the gallery ceiling. Additionally, the staff who would be doing the climbing had to take Fall Arrest training; and the Museum had to have a written Safe Work Procedure detailing how the climbing will be done.

Finally, everything has been put in place, including the purchase of safety harnesses designed specifically for women, as the two conservators who will be climbing are both female.

Conservator Carolyn Sirett was the first to go up and look at how dusty the main yard and mainsail were (very dusty!). She then came back down and we decided that she could carry up the backpack vacuum that is normally used to clean on board the ship.

Carolyn was able to vacuum most of the dust off the starboard side of the mainsail, main yard and the footropes on the main yard.

We will continue to climb up in the rigging as time allows. Mondays during winter hours are best, as it takes time to prepare – check harnesses, get supplies – and we can’t let any visitors on board while someone is working aloft. The Museum will soon be moving to summer hours, so after next week, the work will most likely stop until the fall.

In future, instead of hauling a vacuum up into the rigging, we will be using a converted central vacuum that belongs to the Planetarium/Science Centre. It has a 50-foot long hose, so only that will have to be carried up; it will be much easier.

We will continue to clean off the Nonsuch rigging over the next fall/winter season. Dust can be damaging as well as unsightly, so it should be removed whenever possible. I hope to post some before and after images that will really demonstrate how much dust we’ll be dealing with!

A Blog About a Bog (Diorama that is)

Bogs are fascinating habitats that contain many bizarre species of plants. In the Manitoba Museum’s Boreal Forest Gallery, we have a lovely diorama that depicts what a typical bog looks like. Recently an intern at the Museum, Jon Makar, prepared a report on some of the unusual plants depicted in this diorama. Here’s what he found out!

First off, what exactly is a bog? Bogs are formed when sedges, rushes, and Sphagnum mosses completely cover wetlands, eventually forming a floating mat of vegetation. Bogs are fed only by rainwater and are thus poor in nutrients. Bogs are also very acidic because Sphagnum produces acids as waste products; this makes the bog less suitable for other plants. The acidity of the water in bogs decreases the rate of decomposition, which results in a build up of “peat moss” over time.

A common woody species found in bogs is black spruce (Picea mariana). One reason black spruce can survive in bogs is due its symbioses with special mycorrhizal fungi. These fungi wrap around the tree roots and provide it with nutrients in exchange for carbohydrates. Minerals like magnesium, potassium, and calcium as well as phosphates and nitrates are some of the important nutrients that fungi obtain and share with the tree.

Round-leaved sundew (Drosera rotundifolia) is one of the carnivorous plants that live in bogs. Sundews have unique leaves that are covered with long tentacles, each topped with a drop of clear, sticky mucilage. This mucilage is why sundews get their name, as it appears as if there is always dew on the leaves. When an insect lands on a leaf, it sticks to the tentacles. These tentacles are sensitive to motion and move towards the centre of the leaf upon being irritated. The tentacles wrap the insect up and immobilize it, where after, the glands on the tentacles, secrete enzymes which digest the insect. Studies show that carnivory in plants is an adaptation to low nitrogen environments, such as bogs.

Orchids are another group of plants that can be found in the bog diorama; round-leaved orchid (Amerorchis rotundifolia), showy lady’s-slipper (Cypripedium reginae), yellow lady’s-slipper (Cypripedium parviflorum), and grass pink (Calopogon tuberosus) models were created by the Museum’s diorama artist. All orchids depend on insects for pollination. Lady’s-slipper orchids trap pollinators inside the “slipper” as the walls are-you guessed it-slippery, meaning the pollinator can’t climb out the way it came. A hairy strip at the back of the slipper gives the pollinator footing and allows it to escape through a back entrance, but only once it has brushed past the stigma, pollinating the flower if it had any pollen sacs attached to it. As the insect moves past the stigma it brushes past the anthers, causing new pollen sacs to stick to it and be taken to the next lady’s slipper.

The dioramas at the Museum contain hundreds of fascinating plant species that are usually over shadowed by the large mammals. The bog diorama is an exception to this, focusing instead on the plants and tiny animals that are part of our boreal forests.

We have a new treasure and an unsolved mystery in the Anthropology Department

By Maureen Matthews, past Curator of Cultural Anthropology 

We would love to know who made this beautiful beadwork. 

A few years ago, Mrs. Arlene Kolb purchased this beaded panel in the Value Village shop on Regent Street because she loves handmade things. “I feel that the people making these items were content and focused on what they were doing. They put the effort into making something special,” she told me. After a year of enjoying it, she brought it to the Museum and it happened that there were a couple of Manitoba’s finest beading experts in the museum, Dr. Sherry Farrel Racette of the University of Manitoba Native Studies Department and Jennine Krauchi, one of our foremost beadwork artists. They took one look at the colours, the size of the beads and the pattern and confidently dated it to the 1830s or earlier and were pretty sure it was a Metis woman who made it. The colours of beads and fabric changed after the 1850′s with the introduction of analine dyes. The telltale beads on this piece are are a muted pink, a colour they call greasy yellow and facetted metal beads all of which predate analine dyes.

Please share this blog post with anyone who might know about the history of this marvelous beadwork because we would like to re-establish its broken family ties.
