We have recovered three different graphite rods from the site. Two have ridges, and one is a simple cylinder. One came from the midden, and two came from in or near the clinker pile. They have been really puzzling me since I first saw them in the field.
Now they are washed, it is easier to determine some of the details. I noticed the first one had some kind of brass or metal plate screwed in to one end. The second one had that part broken off, but it seemed to have some kind of black matter wrapped around it, that had been there a long time, as the rod has made a clear impression in the material. The outer surface of the material seemed to be made of some kind of white material.
Having these pieces of information, I started sleuthing. The invention of the internet has made finding information a lot easier in some cases, however, you have to know how to describe things correctly, and also be able to filter through immense amounts of material.
In the end, I am pretty confident that I know what these are, I think they are remnants of old batteries.
There were several kinds of early batteries. In 1859, the Planté lead-acid cell was invented, in the 1860s the Gravity cell/Daniell cell, and the Leclanché cell was invented in 1866. There is also a dry cell battery, which is the one we are most familiar with today.
This means these carbon rods can come from several different types of applications. These could be from a “Horseless Carriage” battery. I have found several examples of rods of the same dimensions and configuration labelled as battery rods from automobiles dating to the 1900s. Date-wise, this is not out of line with other artifacts we have recovered on site. The Canadian General Electric Company, Limited first leased and then bought the parcel in 1900, so perhaps these were lying around something to do with testing or prototypes that someone had taken and thrown out later.
They could also be some kind of storage system, or used to power a telephone or telegraph connection. Other batteries I found were used to power phonographs, or to store electricity from wind-power. It appears as though we might have examples of zinc-carbon and Leclanche batteries present in our assemblage.
My journey down the rabbit hole also helped me to tentatively ID another artifact we recovered. It is a porcelain tube with a bevelled lip on one end. In my searching, I found a discussion of someone testing Leclanche wet cells, and they posted a picture of used zinc, and beside it was something that looks very like what we found.
The next step is to research further and see if I can narrow down a specific use for these batteries, or at the least a particular time period.
We have come to the end of three weeks of the field school, halfway done already. I don’t know about anyone else, but the time seems to have flown by!
With Victoria Day weekend upon us, Professor Conolly decided to give the crew Friday off so they could enjoy an extra long weekend. While they are off enjoying themselves, this gives us some time to regroup and figure out what needs to happen in the last half of the course. As a result, we decided to have a lab day today instead of Friday and try and get caught up on artifact processing.
We had another visit by Marketing and Communications today. As they got to see what we do in the field, we invited them to see the lab work as well. I don’t claim to speak for them, but I think they found it very interesting and illuminating to shadow our progress.
Today in lab was more artifact washing, and bagging by material type, being exceedingly careful to make sure material excavated from the same context stays together. You can spend ages painstakingly excavating a site and have it all come crashing down if you don’t take care to keep the integrity of the material intact. Mixing artifacts across contexts means the interpretive potential they can give you is almost worthless.
In a site like ours, where there has been so much mixture and disturbance over a long time period, clues as to the location of certain types or ages of material is going to be crucial in giving us an interpretive backbone for the site.
Trevor spent some time designing a database to record the context information of the different parts of site we have been excavating. Each time we excavate a portion of the site, it is transformed into a paper record. From there, we transfer the information from paper to a digital format. Sam also started digitising aerial photos of the site and area around the site to create a site map.
Selena began photographing representative samples of the artifacts to include in the reports we need to submit to the Ministry of Tourism, Culture, and Sport. At this point we have managed to wash all the material excavated to date, and most of it has been bagged by context. The next task is to start looking at the different material types and cataloguing the artifacts we have recovered.
Here is some I-Spy to head into the long weekend!
Check back tomorrow for a posting about an interesting artifact I discovered in lab today.
To date, we have been featuring artifacts of the day that are easily understandable as artifacts. Artifacts are things made or modified by humans, so, the coins, buttons, nails, ceramics, glass etc. that we have been finding are all artifacts.
Today’s artifact is a wall! We don’t normally consider things like houses or walls or roads to be artifacts but they are. In fact, we can think of a house as an assemblage of various artifacts that have been combined into a new thing, that just happens to be hard to take into the lab to analyse!
Why is this wall so exciting?
Well, we have made a huge amount of progress on parts of the site. For the most part, the students have been broken into smaller task groups and are working away on particular areas of the site. We are extremely pleased with their progress to date. Even with all this progress, however, there are still some major questions about what is going on with this site!
For example, we have uncovered many walls, but the relationship between these walls and the artifacts around them is still unclear. As we excavate, theories about the site are constantly being created, tested and revised. One big question we have had is if the northern-most wall extends to the west of the visible rectangular area we have already uncovered.
This is very important to find out, as it will tell us which parts of the site were likely outside the structure and which were likely inside. There are several competing theories operating at the moment, and it is quite satisfying to find proof of something that is based on a hunch or impression.
We have bits of walls popping out here and there, but no clear link between them. So, one task today was for Emily and Nic to work on a 2-metre-square excavation unit situated around the known north-west corner of the wall. One hypothesis was that the wall extended to the west, suggesting the structure encompassed a larger area. The competing hypothesis was that the wall ended at the corner visible, and thus the area to the west was actually space outside a structure.
As Emily and Nic worked on their excavation, they learned at some point, a layer of orange sandy soil has been bulldozed around over the edges of the site. We found evidence of this in other areas we have excavated, and we know it has something to do with levelling the surrounding area to construct a playing field.
Under the layer of orange sand was a layer of dark greyish brown soil, which has artifacts in it like nails, glass, ceramics, a horse bit, and other metal fastenings. Excitingly, they also found evidence of a course of stones in line with the known wall.
You can see the known wall behind and to the right of where Emily is standing. It is no longer in line with the buried wall, because at some point, the stones on the known wall have slumped over to the south. Emily is standing outside the structure, and Nic is standing inside the structure.
This suggests the entire area bounded by walls was inside a structure or structures. Other evidence from other parts of the site suggests perhaps this part of the structure may have been dug out to be a basement or root cellar. Faisal and Bjorn have been working at removing more of this fill layer from another section of this potential cellar area. Trevor and Sam have been working hard in a small trench at the south-western part of the site to fully expose one section of wall. Jacob and Brianne have been working on exposing the southern section of wall from the structure. Raine has been working with Shannon and Marielle in a second excavation area across the field.
We also had a visit from Marketing and Communications, and they interviewed some of the students and filmed some video of the excavation. They’ve also published a news article about our excavation.
We look forward to getting back on site for Tuesday and further refining our hypotheses! Tomorrow is a lab day, so I will be reporting on our progress there.
Today’s find was by Brianne, who found this coin while clearing back an area under the clinker pile by a mortared stone wall!
These coins were designed by Leonard C. Wyon in 1858. There are six variants in the obverse. 1858 and 1859 were the first two issue years and portrayed a youthful Queen Victoria in a laurel wreath.
It appears as though Wyon took some artistic liberties, as Queen Victoria was already 39 at the time the effigy was struck. The legend on the obverse says “VICTORIA DEI GRATIA REGINA.” which means “Victoria, by grace of God Queen”.
In 1876, Obverse Style 1 was created, which is a more mature effigy of Queen Victoria wearing a crown instead of a laurel wreath. The lower jaw is very round and curving back to the throat. This style appeared on coins struck from 1876-1886.
A second obverse effigy was produced beginning in 1881 and was used until 1892. This is another more realistic portrait of the Queen’s visage. In this style, you can see the jawline is less taut and there is a dimple under the chin.
There were three other obverse styles, all showing the effigy with increased age changes. Obverse Style 3 (1891-1892) has a quite old-looking queen, with a square chin and a pronounced dimple between the chin and throat. I can’t help but think that Queen Victoria was not happy with that bust, as it only lasted for one year (and it wasn’t very flattering). Mind you, she was 72 at the time!
Obverse Style 4 (1892-1901) is almost identical to Obverse Style 1, with the taut jaw, but the lips are thinner and closer together.
Please visit this site for other images of the obverse styles on non-archaeological coins in much better condition than ours!
Our coin is Obverse Style 1, with the rounded jaw instead of the dimpled jaw.
The reverse design, also engraved by Wyon, depicts a maple wreath with sixteen leaves. The wreath surrounds the legend “ONE CENT” and the date. In some years, the Royal Mint contracted with Ralph Heaton & Sons to mint these coins. Coins minted by Heaton display their “H” mintmark on the reverse. As you can see, our coin has an “H” under the date, which means our coin was minted in Birmingham, at the Heaton Mint.
Traces of the Heaton Mint remain. It was still active until 2003, after a 209-year existence. Although most of the building was demolished in 2007, the facade on Icknield St, Birmingham, UK was preserved and is now a lodging.
Our coin also has a Provincial reverse, which was also found on coins dated 1858, 1859, 1876H, 1881H. The Provincial reverse has medium sized leaves attached to a thin vine and very thin leaf stems. The punch began suffering damage after sinking the first three dies, so as a result all later dies either have damage to the wreath or show signs of re-engraving where the engraver repaired the damaged section by modifying the working die. After 1884, a new reverse was used that has a thicker vine, thicker stems, and larger leaves.
Using the avoirdupois system (common in English-speaking countries before metric) of a 16 ounce pound (7000 grains), pennies for the province of Canada (1858 onwards) were 4.54 grams, and so 100 of them made a pound. Since they are also an inch in diameter, that meant they were often used for quick reckonings, as they had a useful length and weight!
Our penny, though, is a Dominion one, as it comes after the Dominion of Canada was formed. The first Dominion-issued coinage was 1870, but the one-cent coin wasn’t issued until 1876. These pennies are 5.67g (meaning it takes 80 coins to make a pound), 1-inch diameter, and composed of 95.5% copper, 3% tin, and 1.5% zinc.
In 1882, the property was owned by Irwin, Smith and Boyd, and the big sawmill was still in operation.
Today’s artifact of the day is a teaspoon manufactured by McGlashan-Clarke Silverware company.
It was originally plated in silver, and is similar to the Hanoverian style, also known as Rat-Tail. It’s called Hanoverian because the popularity of this pattern spanned the reigns of three kings of the House of Hanover dynasty, George I, George II, and George III (part). The Rat-Tail name comes from the earliest of the Hanoverian pieces, around 1710, as there is a long piece of metal added to the reverse of the bowl of the spoon in the form of a Rat-Tail, and a central ridge in the front stem.
The Hanoverian/Rat-Tail pattern came back into favour towards the end of the 19th century and throughout the 20th century. The Hanoverian form of this pattern, which this spoon belongs to has a pip at the front of the stem and no rat-tail.
Another name for this style of handle is a Fiddle pattern, as the stem resembles the fingerboard of a violin, and the body has cutouts with smooth parallel lines extending towards a rounded terminal.
This teaspoon was manufactured by the McGlashan-Clarke Silverware company, which was the first company to make silverware in Canada. One source I found says the company was founded 1880 in Humberstone (now Port Colborne, Ontario) by Leonard McGlashan and Dr Gardner Clarke. In 1895 the firm moved to Niagara Falls to take advantage of the hydro-electric power available there. The company remained in family hands until it closed in 1955.
For a sad story related to the McGlashan family, check out this article written by Sherman Zavitz, official historian for the City of Niagara Falls.
Another source contradicts this finding a little bit, and provides a date range of 1899 to 1910 for the company and says the company was based in Niagara Falls, Ontario, Canada and also Muncie, Indiana, USA. Obviously a little more research is in order!
This particular teaspoon is stamped Nevada. I am not sure if it refers to the pattern name, or is a trademark name for the nickel-silver. I did manage to find a picture of one in close to original condition.
In terms of dating this piece, we know it has to be older than 1955, as that is when the company closed. Based on the other source, it could even be no younger than 1910.
This piece was found embedded in a pile of clinker, coal, and rusted nails, not far from where the harmonica was found. Tomorrow we are going to investigate under where the pile was and see how the clinker pile relates to the underlying deposits and a wall that is close by.
Here are this week’s I-Spy answers from last Friday’s I-Spy:
This was our first full week in the field, and Fridays are our scheduled lab day. The main task today was to wash as many artifacts as we could so that we can start analysing and cataloguing them.
Our crew is absolutely amazing and we powered through most of the artifacts we have recovered to date! I mentioned before that for every day in the field, there are at least two lab days needed. Washing the artifacts is the first step—next we have to catalogue and analyse this material. When we get to that point we’ll let you have a peek into that process.
So, it is crucial that we stay on top of things, but with this crew I don’t think that will be a problem. I think all of us were ready for a break from digging, and it was a great chance to chat and get to know each other better and take a closer look at what everyone has been finding.
To lead into the weekend, here is some more Friday I-Spy. As usual, answers will be posted on Monday.
And that is two weeks completed of our six-week program! See you Monday.
Today’s artifact of the day came from a really unassuming pile of what looks like a dump of coal, slag, clinker and burnt metal. Nic and Lisa were excavating this context, and discovered a harmonica!
We recovered parts of the comb, two reed plates, and scraps of a leather and oilcloth case.
The comb is the wooden part sandwiched between the reed plates, divided into cells that channel air flow. Most harmonicas now have plastic combs, because wood absorbs moisture from the player’s breath and can expand and affect the playability of the instrument.
The reed plates consist of thin reeds made of strips of metal attached to a rectangular metal plate. Air blown into the comb causes the reeds to vibrate and make the note.
Often the reed plate was nailed to the comb which is the traditional method of attaching them. Other harmonicas have the reed plates screwed in to the comb. Even rarer are cover plates held to the reed plates simply with tension, like some World War II models. Having the reed plates screwed or bolted in means you can replace reed plates when they get worn and start to fall out of tune. In the lab, we’ll be able to determine which is the case with our harmonica.
The last part of the harmonica is the cover plate, which help to direct and project the sound, and also to protect the reeds. While we found parts of the case, we don’t have the cover plates! This is an interesting preservational puzzle. The wood of the comb was (mostly) preserved because the reed plates are made of brass, and the metal salts have acted to preserve the wood. Perhaps the cover plates were a different kind of metal or wood that did not preserve as well as the rest of the artifact.
I took a look at the reed plate, and I believe our harmonica is a tremolo harmonica, using the Weiner system because there are two reeds for each note. Tremolo harmonicas have a unique sound because the two reeds for each note are constructed at slightly different tune, so their waveforms interact against one another and make a warbling sound.
Tremolo harmonicas are very common for playing folk music, and are probably the most common type of harmonica in the world.
Today’s artifact of the day is a sickle. Like yesterday, this was found in the midden area (garbage dump) beside the one structure we are investigating. This sickle is made of iron, and has a sharpened blade edge on the inner curve. It would have been mounted in a wooden handle, which has long since rotted away. Also, the tip has been broken off.
The first settlers in this region would not have had access to any kind of agricultural machinery, so most of the work would have been done through hand tools like the sickle.
This sickle is interesting because it has a smooth blade. Serrated blades appear to have been the preferred choice in American agriculture by a wide margin.
H. Stephens’ 1855 work “Book of the Farm: Dealing Exhaustively with Every Branch of Agriculture” (really, that is the actual title), Volume 2, No 1, has a detailed comparison on pages 329-333 contrasting the cutting techniques of serrated vs. smooth sickles.
The main drawback to a serrated-bladed sickle is that it only cuts on a stroke when the tool is being pulled back to the reaper, and not on the motion of putting the tool into the standing grain.
The smooth-edged sickle is much faster at cutting than serrated sickles, but there are several drawbacks that negate the advantage gained in quickness. Most notably, they had to be made to very exact curvatures in order to achieve the cutting effect. The other drawback was they needed to be sharpened in the field, as the smooth blade dulls much faster than the serrated blade.
Another drawback that occurs to me is the smooth-edged sickles required a slashing motion in order to cut the stalks. Holding a collection of stalks in one hand while slashing at them with a thin whippy blade that can easily cut to the bone seems to be a bit of an occupational hazard!
The blade on this sickle (like the one we found today) is in-line with the handle, suggesting it was used for cutting something that didn’t require a cut at ground level, as the wielder’s knuckles would brush the ground.
Harvesting by sickle was slow and backbreaking work. The invention of the scythe was a major development in agricultural technology even before more recent industrial mechanised agricultural machines. Here is a video showing a comparison of harvesting using a scythe vs. a sickle.
As an interesting side note, we found more Eclectric Oil bottles today. The bottles we have recovered so far must have come from different bottle manufacturers because you can see they are different! The one on the top recovered today is aqua, and the one on the bottom (the Artifact of the Day for yesterday) is more green, and is slightly smaller in volume.
