Dorset Palaeoeskimo Drums from the Canadian Arctic

Examining the drum features and
decorations under magnification
We're back home now and I'm going through notes and photos from last week's visit to the Canadian Museum of History with Chris Wolff.  We were there to view Late Dorset drums recovered from Button Point on Bylot Island off the north coast of Baffin Island, Nunavut.  The artifacts from Button Point were salvaged by Fr. Guy Mary-Rousselière, a priest in the nearby community of Pond Inlet.  The artifacts are stored in the Canadian Museum of History in Gatineau and have been catalogued, displayed, and studied over the years, but there is not a lot of primary documentation accompanying them.  Its an incredible collection that would make a fantastic project for a graduate student.

The Canadian Museum of History

Some of the drum fragments 
We knew that there were two small, nearly complete drums in the collection along with hundreds of other artifacts, but we didn't realize that there would be fragments from more than a half dozen other drums as well.  In total, we recorded 13 additional drum frame fragments in addition to the two near complete drums that we were expecting.  It is possible that some of the fragments would have fit together so we can't say that we found 13 additional drums, but given the variability in the widths, thicknesses, and design details it looks like they represent at least 7 or 8 more drums than we were expecting.  Many of these fragments were identified as drum frame parts in the catalog, although we did add a few new pieces to the sample that were previously unrecognized as drums and we raised some questions about a couple of pieces that we felt may have been mis-identified as drum parts in the past.  Those questionable pieces aren't included in the photos here.

All of the wood pieces that we felt confident in calling drum parts

This drumframe may look incomplete,
 but we are confident that it has just
expanded open from a small 15cm
diameter hoop.
I was most interested in seeing the incised marks on the drum frames.  I've mentioned the sequence of tick marks carved into the frame of the most complete drum in previous blog posts, and alluded to the presence of tick marks on the other nearly complete frame.  This was my first opportunity to see those marks in person and I was thrilled to see a second complete sequence of marks on the second frame.  I'm not going to spoil our paper by telling you what the other sequence is or the surprising artifacts that we saw similar sequences appear on, but I will say that several of the other drum fragments also had similar tick marks on the frames.  Those incised lines seem to have been a common design element on Dorset drum frames and other artifacts in the Button Point collection and I think their placement and order is loaded with meaning.  When we viewed the Inuit drums in the ethnographic collection we didn't see any incised marks on the frames.

The incised lines are very easy to see.  Here are the two sets of 8 tick marks with the line running through them that transforms them into a skeletal motif, or stylized representation of a spinal column.

The reproduction beside the original.
I trimmed the handle down a bit after
seeing them side by side.
There were obvious correlations between the Dorset drums and the Inuit drums that we saw, but there were just as many distinguishing features in the drum manufacture and design that were consistent in all of the Button Point drums and drum fragments but were absent in the ethnographic drums.  I mentioned some of these design elements previously when I documented building the drum reproductions earlier this winter, but it was encouraging to see them appear so consistently across the larger sample.  Things like having the drum skin rest on a beveled, rather than square edge, do not seem to be peculiarities that are unique to one or two individual drums, but consistent features that were common to Dorset drum making more than a thousand years ago on northern Baffin Island.   Chris' experience as a drummer lent some insight to why this beveled edge might be significant and we have an experiment in mind to test the theory.  The gouged holes on the complete frames also showed up on many of the fragments, but were absent from the ethnographic drums in the collection.  We're still working on figuring out the function of those holes, but we noticed a few interesting things about their style and placement that we can report on in the publication.

All of the Inuit drums in the ethonographic collection had handles lashed to the outside of the frame.

The two Button Point drums that had their handles intact had them inserted through gouged holes in the frames.  Many of the smaller drum fragments that we saw had similar holes gouged through them, although not every gouged hole would have been suitable for a handle.  There were also additional holes on the complete frame that must have served other purposes.  We saw holes on the ethnographic drums that were used to tie the frame together or to tie the skin into place, but they didn't look the same as the holes on the Dorset drums.


All in all, it was very exciting.  I think there are some very interesting things that we will be able to say, not only about the mechanics of Dorset Palaeoeskimo drum making, but about how these drums fit within Dorset society and religion, and how they may be related to other drumming traditions in the Arctic.

Studying Arctic Drums

Chris Wolff, Lori, and I spent the last couple of days viewing and documenting Arctic drums and drum parts in the Canadian Museum of History's archaeological and ethnographic collections in Gatineau.  We were primarily interested in the Late Dorset drums from Button Point on Bylot Island.  We thought there was one more-or-less complete drum and a second partial drum, but it turned out there was a lot more to the collection than that.   Both drum frames are actually complete and there were fragments of more than a half dozen other drums from the same site.  Its a much larger sample than we were expecting and the details of the drum construction and decoration are more apparent than we were hoping for.

To put the archaeologically collected drums into context, we also viewed the ethnographic Inuit drums in the Museum's collection.  They are in the same family of drum, but their construction and design differed in several key aspects.  Chris and I plan to prepare a publication on what we found.  It was a fantastic trip and I'll share a few more photos soon.  The collections staff at the CMH were tremendously helpful and accommodating in all our requests.

Harpoon Head Repairs Finished

Two antler harpoon heads and two
ivory harpoon heads
The three harpoon heads that I set out to make and/or repair on Monday are finished now.  The missing endblade on the complete Dorset harpoon is part of a larger order, so I'll hold on to that for the time being, but I can contact the owners of the other two harpoon heads and make the delivery arrangements.  I'd like to hang on to the fresh ivory harpoon head for a few days just to be certain that it is stable.  A freshly carved ivory surface is prone to cracking if its not treated carefully.  I coated the harpoon head in mineral oil overnight at various stages and now that it is done, I've added another mineral oil coating.  The oil should help mitigate the swelling and cracking as the new surfaces react to their new temperature, humidity, and pressure.

The new harpoon head is shown here alongside the broken one that it is replacing.

This is an Inuit style toggling harpoon head for seal hunting.  It is made from walrus ivory for the body, iron for the blade, and brass for the rivet to hold the blade in place.

This is a Dorset Palaeoeskimo harpoon head reproduction with a tip fluted endblade.  It is made from antler and Newfoundland chert.

Two of the harpoon heads are part of complete harpoons.  The one in the upper right corner is another Dorset Palaeoeskimo harpoon head that was given a replacement endblade.  I don't have the complete Inuit harpoon, but the client sent along the ivory foreshaft so that I could ensure that the replacement harpoon head fits.

Making and replacing harpoon heads

Ivory and antler harpoon
heads in need of repair
I'm working on a few harpoon heads this week.  Some will be newly made form scratch and others are repairs or replacements of damaged harpoon heads.  I needed a theme to the week to get me motivated.  I have a long long list of reproductions to get done before I head into the field in June and a short list of people waiting for me to get the work done.  In the photo on the right, the disassembled ivory harpoon head in middle is the broken tip of a complete harpoon.  The roughed out walrus ivory block beside it will be a (hopefully) identical replacement piece that will be fit with the original iron endblade and brass rivet.  The stained harpoon head with the line and foreshaft is a Dorset Palaeoeskimo harpoon head that I made for a client years ago and that needs a replacement endblade made.  I'm aiming to make those two repairs and make a third Dorset harpoon head and tip-fluted endblade from scratch over the next couple of days.

The original harpoon head fell and shattered, but when it is pieced back together you can see its original shape.

The iron endblade with the brass rivet still in place.

Its unfortunate that it broke, but being able to take it apart lets me see details of its construction that would be otherwise hidden.  The red stains are rust marks from the endblade inside the slot.

Having the original piece with me in the workshop helps speed up the work greatly.  I should be able to get this finished tomorrow.

Beothuk Iron Arrowheads

A reproduction Beothuk arrowhead
I'm working on a couple orders right now that are heavy with Beothuk and Dorset Palaeoeskimo artifact reproductions.  Today I made four Beothuk arrowheads by cold hammering square cut iron nails.  Laurie McLean did his MA on Beothuk ironworking and I used a short publication that he put together with the Newfoundland Archaeological Heritage Outreach Program in 2003 as a reference for the work.  He shows there how the Beothuk would hammer nails in the middle to remove the end and start the shaping of the blade.  He also gives some idea of the size of nails used and the arrowheads made from them.

The four arrowheads on the right were all cold hammered and ground out of nails that were identical to the two on the left.  They lost their rust during the hammering. 


I worked two of the nails by chiseling
off the hear.  This is not how the
Beothuk worked them.
I started with 4 inch nails that I bought off a supplier that I found through eBay.  I picked 4 inch nails because I was aiming for a finished arrowhead in the 11 cm range (about 4 3/8").  I knew the nail would get wider through hammering, but I guess I wasn't thinking about how it would also get longer.  The four arrowheads that I made today were all made by hammering and grinding and they ranged in size from 10 to 14 cm long.  For the longest three, I either left the head on the nail as I hammered or chiseled it off flush with where it joined the body of the nail.  I thought that I needed to do that to preserve the length of the finished arrowhead.  But of course that was unnecessary and the better reproduction came from actually following the Beothuk method as it was preserved in the archaeological record.

Based on artifacts recovered from Beothuk archaeological sites, this is how they began working nails into arrowheads.   The nails were hammered flat in the mid section.

When the iron gets foil thin, its easy to bend and snap the nail head off.

A sequence from nail to
completed arrowhead
To work the nails, I hammered them cold on an anvil with a metal claw hammer.  I made a few strikes with a hammerstone and it worked fine, although the long handle on the hammer made things much easier.  To grind the blade down to size and make it symmetrical and sharp, I used a bench grinder for the coarse work and an hand file for the lighter work.  Again, a stone abrader worked fine, but I opted for something with a longer handle to actually do the work.  I did a small amount of hammering on the tang as well to narrow it.  This also added length to the arrowhead.  In the end, the hammered arrowhead was more or less the same length as the nail that it was made from, even with more than 3 cm removed from the head end.  The four arrowheads are all more or less correct, although as a set they feel large.  I have some 3 inch nails on the way and I think working them in the same way will give me some smaller points that will create a better collection.  I'd like the points to be in the 7cm to 11cm range when completed.

Its possible that some of the little nail heads were ground into scrapers.  It makes sense to reuse those little pieces somehow.

Drone Practice

The houses and powerlines are a
couple hundred metres away.  Wide
open spaces are a must.
Over the Easter weekend I had a chance to tag along with a couple friends out for the inaugural flight of their new 3D Robotics multirotor drone.  The ultimate goal is to use the drone to assist in archaeological mapping and overhead site photography, but on this first attempt the goal was to simply get it off the ground.  This was my first time seeing a multirotor fly and I was surprised by how quiet and stable the flight seemed, even on a somewhat gusty day.  The vehicle seems perfectly suited for aerial photography at the site level and probably larger area mapping, but it will require a lot of practice.  Being on hand to see a new operator try one for the first time really impressed on me how difficult it is to learn to use one of these safely and confidently.  It definitely requires practice in a wide open space, a steady hand, and spotters on the ground to help keep an eye out for trees and powerlines and to run interference on the throngs of kids that are attracted to the spectacle. 

Marc on the controls.  

Discussing the flight plan.

Its remarkably steady in the air, especially in "loiter" mode.

A second multirotor was on the scene as well, although it was having a bit of a rough day flying.

The drone has a pretty robust chasis, but the blades are necessarily light.  The slightest tumble was enough to break two rotors. The blades are designed to be easy to replace.


Like any aircraft - takeoffs and landings were the trickiest part.

In the air, it was very quiet and stable. I can't wait to see the results once the camera gets mounted.

Sheshatshiu, Labrador Intermediate Period Collection

A 3000 year old toolkit
Here's a final look at the Intermediate Period reproductions that I've been talking about for the past few weeks.  They are based on artifacts recovered in Sheshatshiu, Labrador under the direction of Scott Neilsen.  The site is dated to around 3000 years ago and will be the focus of a new exhibit in the Labrador Interpretation Centre in North West River.  Aside from the two cobble tools (the quartzite hammerstone and the coarse pestle) I've documented most of these pieces in previous posts, which are indexed here:



If you would like to learn more about the archaeological site that these reproductions are illustrating, you can visit the Newfoundland and Labrador Archaeological Society's YouTube channel and watch Scott's April 2, 2014 talk at The Rooms called "Archaeology in Sheshatshiu: A Review". 

These are the artifacts that the reproductions are based on.  Only one of the three side-notched projectile points was reproduced (the top one) and the large reddish quartzite biface was used as the reference for both a spear point and adze blade.

For this quartzite hammerstone, I went through my bag of hammerstones and found one that had a similar size and shape to the Sheshatshiu artifact.   If you've attended a MUNArch flintknapping workshop in the past few years, there is a pretty good chance that you used this hammerstone and therefore you helped make this reproduction.

This is a little rougher looking cobble that is meant to represent a possible pestle in the collection.  Its a softer rock that probably wouldn't last long as a hammerstone, but it may have been used for grinding ochre or pulverizing other materials at the site.  Mostly unmodified rocks like this present their own problems when trying to reproduce them.  Finding a cobble that matches the artifact is kind of like finding a perfect match for a specific snowflake.
 
All of the pieces.  Quartzite, chert, charcoal, softwood, spruce, tamarack, rawhide, gut, sinew, hide glue, spruce gum, red ochre, caribou skin, beach cobble, caribou antler

The quartzite biface hafted as a spear point is one of my favourite pieces in the collection.  It has a nice weight to it.

 
Seeing this coming at you would suck, if you were a caribou.

The scraper, hafted in an Innu style handle.

A side-notched point hafted with red ochre and spruce gum into a wood foreshaft with sinew lashing.

A grey banded chert knife hafted in a caribou antler handle.  The handle is designed to fit into the spear as a short foreshaft.

The red quartzite biface is shown here hafted as an adze blade in an antler socket lashed to a wood handle with rawhide.
