Hafted Necklaces

I'm off to Alberta to visit my dad and stepmom for a few days. I set up a few pre-scheduled posts to feed to the blog while I'm away. If I'm able to make updates while I'm at the farm, I will, but if not, I've got a few short photo based posts ready to go. Here's a look at the hafted point necklaces that I showed on the stalk last Friday. Now that I have a good recipe for a durable red ochre paint, I'm thinking about introducing hafted Beothuk style points as a new product for the wholesale season next spring. Imagine these, but done in local Newfoundland chert and stained with red ochre.

How does a Barbed Harpoon Work?

The oldest style of harpoon in the world is the barbed harpoon. A harpoon is a spear-like device with a detachable head tied to a line. When the barbed harpoon head is embedded in the flesh of the prey animal, the barbs grip the tissue and the hunter has a secure line attached to it. Its similar to how a fish hook catches a fish, but its used on larger fish and sea mammals. Sometimes the hunter holds the other end of the line and sometimes the line is attached to a float that drags behind the prey, identifying its location, preventing it from escaping and exhausting it.


In Newfoundland and Labrador, the Maritime Archaic Indians used barbed harpoons similar to the one labelled above. They most likely used it for seal hunting. This is my best guess for how the harpoon might have looked. If you visit the Maritime Archaic exhibit at The Rooms, you'll see this label next to the Maritime Archaic Indian foreshafts like the one in this reproduction: "Whalebone foreshafts were used for sea mammal hunting. Exactly how they functioned has puzzled archaeologists for decades." That's still totally true - take all the reproductions that you see on these pages with a grain of salt. I wasn't there.

However, in my kitchen, I did finally get all of the components of the ballistic gel seal working the way they should; skin, fat, and meat. For the meat layer, I tried denser ballistics gel alone, but it wouldn't hold the harpoon head securely enough when I tried to pull it out. Next I tried lacing the dense gel with sinew threads, but the barbs just grabbed them and pulled them out like spaghetti on a fork. Finally, Lori gave me some cheese cloth, which I cut into circles and suspended at various depths in the gelatin. The loose weave was punctured by the antler harpoon head, but there was enough form to the cloth that it held together and gripped the harpoon head when I tried to pull it out. I don't think I quite have a realistic muscle consistency, but by increasing the density of the gel and adding more and more cheesecloth layers I know I'll be able to have a lot of control over the accuracy of the model.

In the tests with the barbed harpoon, we got lucky with two different views of the barbs in action. On the first attempt, my bad aim and a wobbly gelatin tower caused the harpoon to go astray and not penetrate the "meat" layer. However, the barbs snagged securely on the rawhide skin layer. In the second photo below you can even see the path the harpoon head took through the gel before being pulled back up to snag on the skin.


On the next test, the harpoon penetrated deep into the "meat" layer and through 3 of the 4 layers of cheesecloth. The "meat" had enough substance to grip the barbs of the harpoon on the way out. It held firmly enough to prove the concept and get these photos, but in actual experiments I think I'll use a denser gelatin (in this version I used 1 packet of knox gelatin for every 100ml of water) and more layers of cheesecloth.






Its interesting to note that when the harpoon head grabbed on the skin layer it used the barb closest to the line hole and when it grabbed in the "meat" it used the barb closest to the tip. There is a lot of variability in Maritime Archaic harpoon heads of this style, with anywhere from 1 to 4 barbs along one edge or both edges. That would be another interesting thing to examine in these experiments - the differences in the number and arrangement of barbs on a barbed point.

I'm loving this project - if testing the ballistics gel is this much fun, I can't wait to start actually testing the harpoons!

Filling Orders and Goldstone

I've been trying to wrap up some loose ends before heading to Alberta for a few days next week. The house clean-up has been proceeding slowly and I've been working on filling craft fair orders, preparing quotes and invoices for clients and throwing out some particularly rancid gelatin that was forgotten during the hectic craft fair weekend. The biggest block of time has gone into preparing a wholesale order for The Rooms Gift Shop. Hopefully it will be ready for delivery later today or (more likely) tomorrow. I can pull some of the order from pieces I prepared for the craft fair, but there is so much variety in the order that I need to make several pieces from scratch.

The arrowheads hafted onto shafts in the photo are going to be hafted necklaces. I drill a hole through the wood, cut the shaft off close to the arrowhead, and string them on leather cord. I'm using some particularly nice obsidian in these necklaces and 2 of them will be for sale at The Rooms Gift Shop shortly.

There will also be a few goldstone pieces in this order. Goldstone is a manufactured material that has copper flakes suspended in glass. The process was discovered in the 17th century and patented in Italy in 1670. The reason I use it is that there were several goldstone artifacts found in the excavations at Ferryland, including gold rings and pendants. The Ferryland artifacts appear to have been hidden in 1696 when the French attacked the site. I think its interesting that this material shows up in the New World within a couple decades of its being patented in Italy.

What are the parts of a Toggling Harpoon?

Here's a quick look at the parts of a Dorset Palaeoeskimo toggling harpoon and some of the tests to find a good ballistics gel seal to do harpoon experiments with.


This style of harpoon is used to attach a line to a seal. The hunter gets close enough to the seal to jab it with the harpoon, the harpoon head detaches and toggles beneath the skin of the seal. The hole where the line attaches to a toggling harpoon is near the middle of the harpoon head, so when the seal tries to escape, the harpoon head toggles, or turns sideways. A toggled harpoon head is bigger than the hole it made going in and is firmly embedded in the hunters prey. The line is used to haul the seal out of the water so that the hunter can finish it off.

That toggling action is one of the things I'm trying to illustrate with the ballistics gel seal. This particular video still doesn't show the harpoon head toggling, but I did learn a lot from it. One thing it illustrates is that the skin and fat layer of the ballistics gel seal work very well. They offer the right amount of resistance and are good approximations of the outer layers of a seal. The Dorset Palaeoeskimo harpoon heads from Newfoundland that I have modelled this harpoon on have a single line hole, and I believe that the line must have been secured to the harpoon head with a big knot of sinew on one side. On the test in the video, the sinew knot bulged out of the smooth contour of the harpoon head. It created a raised bump a couple millimetres high, but it was enough to snag on the rawhide skin. The resistance from that tiny snag was enough that the harpoon was bound up and the whalebone foreshaft broke. I learned two things. First, if I'm going to use a sinew knot to secure the line, it needs to be flush with the surface of the harpoon head and secondly, the forces involved in the experiment are great enough that things break when they go wrong. Which is also good, because examining how things break is very useful information when studying broken and discarded tools in the archaeological record.

After the foreshaft broke, I pushed the harpoon head down into the gel manually and it did toggle for me when I pulled on the line. In the photo below, you can see the gel tube suspended from the toggled harpoon head and line. The gel is still a little opaque to see everything that's going on, but you can make out a few interesting details. In the overhead shot, you can see the hole that the endblade made and the shadow of the harpoon head lying beneath the rawhide skin. In the inset shot you can see the endblade, which detached when the harpoon head toggled. It marks the depth that the toggling occurred, although the harpoon head itself squished up through the ballistics gel "fat" layer and is actually snagged just below the skin. You can see the rubbery rawhide skin flexing upward under the tension.

Craft Fair Recovery

The Fine Craft and Design fair went very well. My sales were on par with previous years at the Convention Centre, which I take as a big success, given the move to a new venue, the new 10-day format, the recession, and H1N1. There were lots of reasons to expect things to be down this year, but they weren't. The Arts and Culture Centre had a great atmosphere and I didn't hear from a single customer or exhibitor who didn't like the new location. I saw lots of old friends and met lots of new people. We even did a little shopping ourselves -- including this great hand forged pot rack from Green Family Forge.

One trend that was strong this year was an interest in flintknapping workshops. There was enough interest that I'm planning to do two workshops early in the new year, one on pressure flaking and one on percussion knapping. I'll post more details as they get worked out, but for now, if you are in the St. John's area and interested in learning to knap, send me an e-mail and I'll keep you posted.

Today is a bit of a slow day. The 12 hour days at the fair are long. I find it to be a big shock going from the isolation of the workshop in the weeks leading up to the fair to being immersed in crowds of Christmas shoppers for 5 days straight.

I'll slowly start re-assembling the house today. There's always a mess to clean up in the house after a craft fair because everything else leading up to the fair takes a back seat. This year the problem was compounded by the fact that Lori was sick in bed for the week and a half leading up to the fair. I was left unsupervised during that entire time and the craft fair preparation crept into every nook and cranny of the house.

Only Three Days Left!

So far, the Fine Craft and Design Fair at the Arts and Culture Centre in St. John's has been fantastic! I'm loving the new venue and there were actually artisans in the first fair who enjoyed themselves so much during the first 5 days that they signed up to do it all over again at this week's fair!

The fair is Open 10AM to 10PM on Friday and Saturday and 10AM to 6PM on Sunday. Free Parking and Admission.

Don't forget the Flintknapping demonstration - Saturday, November 14th, 10AM to 12 Noon. Hope to see you there!

Remembering

When I think about Remembrance Day, I think about my dad's dad, Gustav Rast. He enlisted with the Polish army in World War I. At the time it was a good opportunity for a young man. He joined because they would send regular pay back to his family. Although living in Poland, grandpa was German and his brothers joined the German army, but grandpa didn't like how strict the Germans were so he joined the Polish forces instead. However, the fighting didn't end for Gustav when the Great War ended in 1918. Poland found itself an occupied country and grandpa continued fighting against the Bolsheviks between 1918 and 1921 for Poland's Independence from Russia.

Even when the fighting was over and Grandpa sold his team of horses for passage on a ship to Canada in the 1920s the war never left him. After a year of saving, he sent money back to Poland to bring his young wife and 3 small children (they had five more later) over to Saskatchewan. He exchanged letters for many years with his brothers who continued to live in Germany after the War, but when World War II broke out Grandpa destroyed all those correspondences. Grandpa didn't talk to his kids about his experiences in the First World War at that time, that would come later.

During World War II grandpa became very paranoid. German immigrants in Canada weren't allowed to own guns. Grandpa had a .22 rifle that he used for hunting rabbits to feed the family. He wrapped it in tar paper and took it out on to the prairie to hide in a rock pile until after the war. His oldest son, Erwin, followed grandpa to see where the gun was hidden. Erwin would have been 12 or 13 and he took his seven or eight year old brother Otto out to the rock pile to show him the gun. Erwin convinced Otto that since he knew where the gun was now he would get in trouble if his parents ever found out that Erwin was sneaking out and playing with it. Eventually Erwin broke the gun and threw it away. When grandpa went to retrieve the .22 after the war and found it missing he spent years wondering who found it and was convinced that the government was watching him. Erwin died in a car accident when he was still a teen and Otto didn't want to tarnish his memory with his father so he never told Gustav the truth about the rifle.

Grandpa didn't talk about the war until much later, but he spoke of it often after my grandma died. My earliest memories of my grandpa are of him sitting at his kitchen table in Saskatchewan talking to my dad in English and German about the War. It was over 60 years later and those memories were still right on the surface for him. He talked a lot about his friends and how random it was between who lived and who died. He'd say over and over again "Where was my bullet? So many good boys got killed... where was my bullet?" In fact, he was shot on at least one occasion and he could recall listening to the two Russian soldiers standing over him debating whether or not to shoot him again. They decided to leave him there. Grandpa could understand Russian and he heard one soldier convince the other not to waste a bullet, because this one would die anyway. On that occasion the Red Cross found young Gustav and patched him up. But thinking back, grandpa carried all those wounds in his head for the rest of his life. He dwelled on all his friends being lost and the many times he was held as a prisoner of war.

On my mom's side, she lost an uncle, Leonard Johnson, in World War II. He was an observer on board an RCAF bomber and went missing on July 29, 1943 in a raid over Hamburg. Like so many Canadian families, my mom's family were left wondering for decades whatever happened to him. In the family portrait on the left, Ragna was my grandma. Leonard was missing for years, although his grave has been located since. I believe he's buried in the Netherlands. Maybe someone in my family reading this could help fill in more details on my Great-Uncle Leonard.
