2020 Archaeology Wrap-Up

Lead seal stamed with the mark of the Compagnie des Indes.

The second half of the archaeological field season had similar themes to the first half (see the first half recap here). Again, the most interesting artifact came from the central root cellar. It was a lead seal stamped with the mark of the Compagnie des Indes. The CDI was a French colonial enterprise chartered by the king. The seal would have been attached to a bolt of cloth or other textile imported by the company. It dates to between 1717 and 1769. This, combined with the stratigraphy (layers of soil) surrounding it, indicates that this cellar was in use during the French occupation of the house (mid-1730s to early 1760s) as well as during the later British occupation.

Possible French wall trench.

During the final week of the field season, we saw the first possible evidence of the north wall of the house. It is a strip of gray sand cutting through gold sand. In other units of the southeast rowhouse, the French house is a few feet narrower along the north wall than the British house, but has a porch, which the British house does not. The square the possible trench appeared in is the deepest in its east-west row (the row 210 feet south of the water gate), so it remains to be seen if it extends to the east and west. We do not expect to find the British wall trench and French porch joists until we open the row of squares to the north (the row 205 feet south of the water gate). After the excitement of removing the deep post in the first half of the season, we did not find the bottom of any more squares this summer. We opened the final two squares in the 210 row in the second half of the season. The easternmost is currently at the modern/colonial interface. The westernmost is in the layer of rubble created during the 1781 demolition of the fort. As was the case elsewhere in the house, there were a variety of ceramic sherds present. These included a fragment of a creamware handle, possibly from a pitcher, and a fragment of a polychrome tin-glazed earthenware teacup, similar to one found late last season.

Site packed for the winter.

We have now packed the site for winter and returned to the lab. Watch for a blog post in late winter to see what we learn as we clean and research this season’s finds.  

Michilimackinac’s Artillery

Over the past few years the staff at Mackinac State Historic Parks has diligently been adding reproductions of Michilimackinac’s artillery throughout the site to provide visitors an accurate representation of what the site looked like in the 1770s. Join Curator of History Craig Wilson as he takes us for a tour of Michilimackinac and its artillery.
 

At Last…

The site being prepared for the field season. The plastic containers protected wood posts under the plastic sheeting and straw over the winter.

   After a very long wait, MSHP archaeologists were excited to remove the straw and plastic sheeting from the archaeological site and begin preparing the site for excavation. Unfortunately, there was a lot of slump, especially along the north wall, so there is a lot of clean up ahead. The next step is to re-establish the grid strings used to record where features and artifacts are found relative to the overall master map.

   This will be our fourteenth season of excavation at House E of the Southeast Rowhouse. The rowhouse was constructed in the 1730s and this unit was owned by Charles Gonneville for most of the French era at Michilimackinac. By 1765 the house was owned by an as-yet-unknown English trader. Our initial research question for the project was how does an English trader’s house look different from a French-Canadian trader’s house? The early answer is that there is more trade silver and ceramics. This trader not only had fashionable furnishings, but dressed stylishly as well, based on the sleeve buttons and other adornment items we have recovered.

   Our main goals for this summer relate to the deep features previously exposed. We think we are nearing the bottom of the root cellar in the southeast corner of the building and hope to complete its excavation this season. There are two more deep features, which intersect, in the west and south-central areas of the house. We hope to better define them this season.

   As with any archaeological excavation there will be surprises that raise new questions. You can come watch history being uncovered at Colonial Michilimackinac every day from June 12 – August 22, from 9 am until 5 pm, weather permitting. You can also follow along all season on the MSHP blog and social media channels.

Mackinac Island Airport Archaeology

Refuse revealed by the stripping of the runway.

In September 2011 all of the pavement at the Mackinac Island Airport was removed prior to the regrading and relocation of the runway to correct sinkholes and a hump in the runway. The airport was originally established in 1934. Maps from 1902 and 1913 show that the area was used as a dump. The stripping and regrading exposed and removed several areas of refuse.


When examining a dump archaeologically, it is not productive to try to salvage, or even record, every object. Instead the goal is to sample enough artifacts that can be dated to determine the timeframe in which the dump was used. In this case these artifacts were primarily ceramics and glass. In general, the glass suggested a date of the first two decades of the twentieth century, matching the maps. The ceramics skewed slightly earlier, probably because they have a longer use life before being discarded.


Example from Grand Hotel when operated by Planter’s (1900-1918).


Over four hundred ceramic sherds were collected, including fragments of earthenware, stoneware, porcelain and lots of hotel ironstone vessels. Marked examples from Grand Hotel when operated by John Oliver Plank (1887-1889) and Planter’s (1900-1918) were recovered. Other forms collected include marmalade and mustard containers, a candlestick, matchstick holders, porcelain doorknobs, architectural tile, and electric insulators.


Three hundred fifty-six bottles and other identifiable pieces of glass were recovered. These included wine, liquor, beer, mineral water, grape juice and other beverage bottles. Six Michigan breweries were represented: Detroit Brewing Company, Goebel Brewing Company, Koppitz-Melchers Brewing Company and Stroh Brewing Company, all of Detroit, as well as the Grand Rapids Brewing Company and Soo Brewing Company. Other consumer goods included condiments, salad dressing, capers, olives, prescription and over-the-counter medicines, skin cream, perfume, ink, and a variety of cleaning products. These products came from across the Atlantic Ocean and as close as Bogan’s pharmacy on Mackinac Island.

Electricity came to Mackinac Island in 1911. This dump spanned the transition. Both lightbulbs and oil lamp parts were recovered.

Fire extinguisher.

Metal artifacts are much harder to recognize from just a fragment. In addition to lamp parts, cooking utensils, buckles, horseshoes, and enamelware vessels were recovered. Some of the more obvious and interesting metal artifacts included a fire extinguisher and part of a push lawn mower.

What’s Growing the Garden? Cabbage!

Cabbages are attractive vegetables. They come in a variety of shapes, textures, sizes and colors. Many gardeners in the 18th century, including Michilimackinac resident John Askin, considered cabbages to be an essential vegetable in the garden. They keep well, are versatile in the kitchen and generally low maintenance. They can be placed out in the garden earlier than crops like beans, cucumbers and melons and are quite cold hardy. This winter, we even had one cabbage winter over in our King’s Garden. It was quite a surprise, especially since it was covered in snow for a few months with no protection at all.

The downside to these vegetables is that they are incredibly tasty to slugs. The gray beasts like to get inside the cabbage heads and munch away. Just when it seems like all the slugs have been picked from the leaves, there are five more that pop out. In the 18th century, gardeners had many solutions to deal with slugs, but most come down to manual removal. At Michilimackinac, we have found that encouraging toads in the garden has also proven useful.

Right now, our cabbage seedlings for 2020 are started and doing well. The transplants will be planted out in early to mid-May and when they are big enough, they will find their way to our daily food programs at Colonial Michilimackinac. If you have never grown cabbage, take a cue from history and give this beautiful and useful vegetable a chance. Be sure to visit our website for more updates, and check out Mackinac Associates, a friends group which makes many of our programs and exhibits (including the gardens) possible at all of our historic sites.

What’s Growing in the Garden? Carrots!

Carrots in the ground.

We have begun our spring cleanup of the gardens at Michilimackinac! It Is the best time. Every year we find a few unexpected things, and this week we came across a number of forgotten carrots. We are usually quite meticulous about digging our root vegetables and storing them for use later, but it seems that these escaped our shovel. Surprise!

What will these be used for? Well, 18th century sources abound with recipes and uses for carrots. Some books recommended them as a cure for everything from cancer to asthma. Cooks turned the root vegetable into puddings, added them to soups, and used them in salads. One of our favorite historic ways to use carrots is from a recipe by E. Smith that was published in the Compleat Housewife in 1736:

To make Carrot or Parsnip Puffs

Scrape and boil your carrots or parsnips tender; then scrape or mash them very fine, add to a pint of pulp the crumb of a penny-loaf grated, or some stale biscuit, if you have it, some eggs, but four whites, a nutmeg grated, some orange-flower water, sugar to your taste, a little sack, and mix it up with thick cream. They must be fry’d in rendered suet, the liquor very hot when you put them in; put in a good spoonful in a place.

They end up being sweet and deliciously greasy.

While it is not uncommon for root vegetables to winter over in the gardens at Michilimackinac, it still always seems like something that shouldn’t be possible. Check back later to see what other things are happening this spring at Michilimackinac.

Battlefield Archaeology at Wawashkamo Golf Club

One of the most unusual archaeological projects to take place on Mackinac Island was a metal detector survey of the portion of the 1814 battlefield located on Wawashkamo Golf Club. The project was carried out in May 2002 by the Heidelberg (Ohio) College Center for Historic and Military Archaeology under the direction of Dr. Michael Pratt and funded by the Wawashkamo Restoration and Preservation Fund.

1814 Battle of Mackinac Island.

The August 4, 1814 battle was always known to have taken place on the Dousman farm on either side of what is now known as British Landing Road. This survey was designed to determine what might be left in the ground on the western side of the battlefield after 85 years of farming by the Dousman and Early families, followed by 102 years as a golf course. Three different types of metal detection instruments were used in order to locate ferrous, brass, copper, silver, lead, nickel and gold artifacts. The fairways were systematically “swept” to locate possible concentrations of artifacts. Four areas of interest were located, which were then intensively surveyed. Two hundred sixty-five artifacts related to the battle were located. These included United States Infantry and Artillery buttons, spent and dropped rifle, musket and buck shot, a piece of iron canister shot, trade gun parts, an 1807 U.S penny, and three nearly complete clasp knives. Additional artifacts recovered related to the Dousman and Early farms and all eras of Wawashkamo Golf Club.

The clusters were located on fairways 1, 5, and 9 and the east end of fairway 8. Spatial analysis of the battlefield artifacts indicated that the survey area included the path of Lieutenant Colonel George Croghan’s regular troops advancing and retreating along British Landing Road, and the possible location of Major Andrew Holmes’s unsuccessful flanking attack and death. The 2002 survey demonstrated that significant archaeological resources have survived at Wawashkamo. The results did not re-write the story of the battle, rather they fleshed out the written record and provided a tangible link to the only battle ever fought on Mackinac Island.

Ezekiel Solomon at Michilimackinac

With Passover underway, let’s take a closer look at one of Michilimackinac’s merchants: Ezekiel Solomon, who was probably Michigan’s first Jewish resident. (more…)

A Model 1884 Springfield Rifle

The .45-70 Springfield Rifle.

The Buffington sight. A second adjustment screw (not visible) swiveled the entire sight left or right.

During the summer months, visitors to Fort Mackinac are able to see a real piece of history in action every single day. Historical interpreters representing soldiers from the 23rd Regiment of Infantry perform rifle firing and drill demonstrations throughout the day. The weapons they carry, the .45-70 Springfield rifle, are all 19th century originals, making them at least 130 years old. Let’s take a closer look at one of these fascinating weapons.

 

Introduced in 1873, the .45-70 remained the standard issue arm of the American army for 20 years. A single-shot weapon, the rifle derived its name from the cartridge it fired: a .45 caliber bullet propelled by 70 grains of black powder. Over the course of its service life, the army refined the rifle several times, making almost yearly changes to the design to reflect the realities of daily use and at the suggestion of officers and enlisted men. Only rarely did these design changes cumulatively result in the designation of a new model, but in 1884 the army approved a “new” design incorporating improved features.

 

The improved cleaning rod, with tapered button tip.

Note the knurling on the trigger and on the hammer.

This Model 1884 displays many of these design elements. The two most prominent “new” features are the sight and the cleaning rod. The sight, designed by Lt. Col. A.R. Buffington of the Ordnance Department, includes a leaf that can be flipped up and adjusted to sight the weapon at ranges up to 1,400 yards. It also includes an adjustment screw to compensate for windage- by turning it, the entire vertical leaf swivels right or left. The cleaning rod, meanwhile, incorporates the flared button head adopted in 1879 and put into widespread production in 1882. The breechblock is stamped U.S. MODEL 1884, although in reality these stamps were not added to new rifles until 1886, and weapons marked this way did not enter widespread service until 1887. The rest of the rifle incorporates several other design improvements adopted over the years, such as knurling on the trigger and hammer, which was intended to improve a soldier’s fingertip grip on these critical pieces.

 

The star symbol stamped next to the serial number (it looks like a flower) indicates that this rifle was probably rebuilt at an arsenal at some point.

The rifle’s breech in the open position. When opened after firing, the weapon automatically ejected the spent cartridge, allowing a soldier to quickly reload.

This particular rifle has a serial number in the 141000 range, indicating that it was probably originally produced in 1879 or 1880. How, then, can it incorporate features only authorized in 1884, and not actually put into service for a few more years? The small five-pointed star or flower next to the serial number most likely indicates that this weapon is an arsenal rebuilt. In 1879 the Springfield Armory began collecting older .45-70 rifles and using some of the parts to build new weapons, which were held in reserve or eventually issued to various state units (the forerunners to the National Guard). Furthermore, since the rifles were built using entirely interchangeable parts, after the weapons left frontline military service and entered the civilian market (which many did- they are still relatively easy for collectors to obtain) it was simple for gun brokers and owners to cobble together “new” weapons with a mixture of parts from different model years.

 

In any case, this rifle, and the others in daily use at Fort Mackinac, are truly history that you can see, smell, hear, and touch. Our interpreters carry rifles of both the 1873 and 1884 models, with many of the small variations added each year. We even have a few rifles equipped with ramrod bayonets, an experimental design attempted on three different occasions in the 1880s. These weapons had a small, sharpened metal dowel mounted under the barrel in lieu of a cleaning rod in an effort to eliminate the need for soldiers to carry a separate bayonet and scabbard. Historically, one of the two companies of the 23rd Infantry stationed at Fort Mackinac from 1884 to 1890 were issued the experimental ramrod bayonet rifles for evaluation. When you visit us at Fort Mackinac, be sure to ask the interpreters about their rifles- they’re a fascinating link to the past!
