2018 Farm Show


This year is the 102nd anniversary of the Pennsylvania State Farm Show. According to the Farm Show web site it is the “largest indoor agricultural exposition in the nation, with nearly 6,000 animals, 10,000 competitive exhibits and 300 commercial exhibits.” 

The Section of Archaeology at The State Museum of Pennsylvania will again host an exhibit, complete with an authentic replica of a 20-foot long dugout canoe. Our exhibit is entitled Foragers to Farmers, the Development of Agriculture in Pennsylvania. As you read in our last blog, Native Americans and then early settlers had a close connection to the land, which served to provide them with food and medicine. This exhibit explores some of those plants and how they were utilized by our ancestors and showcases some of the artifacts from Pennsylvania.

Farming is more labor intensive than hunting and gathering and there is a debate in archaeology as to why early Indian populations in Pennsylvania gradually began focusing on seed plants such as goosefoot, lambs quarter, and maygrass for food; eventually growing these plants in gardens and finally adding maize to their diet. The dependence on maize in the diet begans about A.D. 1000 eventually leading to the  development of large villages and significant changes in social organization. During the 1700s, European farms began to dominate the region and farming changed to include livestock and grains. By the late 19th and early 20th century, farming became more mechanized and fed huge numbers of people. The artifacts on display document this change over the past 5,000 years. 

 
 
A corn grinding station utilizing stone tools allows visitors to experience the process used by native peoples.  Corn quickly became a food staple after A.D. 1200, spurring dramatic social changes.  Small egalitarian groups of people grew into tribal societies. Another station will share information on types of native foods still utilized today and some recipes that you can try at home.

This event is always an excellent opportunity for the State Museum staff to connect with the community.  We talk to an average of 40-50,000 visitors each year at the Farm Show and share our knowledge with interested citizens of the Commonwealth.  One of our goals in reaching out to the community is to share the significance of archaeology and to stress the importance of recording archaeological sites.  The Pennsylvania Historical and Museum Commission is the state agency for preserving our historical and archaeological heritage.  The State Historic Preservation Office (SHPO) records and maintains the files for all known sites across the Commonwealth.  This database of information enables state agencies such as PENNDOT to plan for highway projects that will have the least amount of impact on archaeological resources.  Archaeology is a labor intensive and an expensive undertaking.  Avoiding sites reduces the expense of building roads or bridges. 

The Society for Pennsylvania Archaeology (SPA) is also participating in our exhibit as they have in past years.  Representatives are on hand to answer questions about the Society and membership which includes the biannual journal, Pennsylvania Archaeologist, newsletters and meeting announcements.  As an additional benefit of joining at the Farm Show you will receive three past issues of the SPA journal.

Our booth will be located opposite the carousel in the Main Exhibition Hall of the Farm Show Complex.  The Farm Show runs from Saturday, January 6 through Saturday, January 13, and is open from 8:00 am to 9:00 pm each day except the 13th when it closes at 5:00 pm. Mark your calendar and plan your visit to the 102nd Pennsylvania Farm Show (http://www.farmshow.pa.gov/Pages/default.aspx). Be sure to join us at the State Museum’s booth and take a ride in the dugout canoe.

The Edible World Around Us: Plant Use in the Past and Present

There is an edible world around us that was expertly known and used for millennia before the arrival of the first Europeans to North America. Even the early settlers had an acute knowledge of plants and their culinary and medicinal uses. Today, much of the knowledge once considered essential for life has been traded for easily accessible and neatly packaged foods and medicines. It can be easy to forget that much of what we take for granted, both in cuisine and medicine is deeply rooted in the past.

Indigenous knowledge of the natural world has been passed from generation to generation through a rich oral tradition. The study of plants and their uses through cultural knowledge is called ethnobotany. Beyond the staples corn, beans, and squash, famously referred to as the three sisters, a multitude of other plants were utilized by the prehistoric people who thrived in North America. In many parts of the world, similar traditional knowledge persists to this day out of necessity or tradition.

Plant remains are relatively rare in Pennsylvania’s archaeological record due to the poor preservation of organic material, but plant use is well documented in ethnographic accounts of historic tribes and knowledge held by modern indigenous communities. Some indigenous groups have been reluctant to share traditional medicinal knowledge with outsiders out of concern that it will be used by pharmaceutical companies wishing only to profit from the information without respect or acknowledgement to the indigenous communities and their intellectual rights.

In North America, many species which we today consider to be weeds or nuisance plants had culinary or other importance to indigenous people. The plants most often used by Native Americans were also the most common and in many cases, are still common today. Plants were collected with respect and attention to conservation to ensure its survival. The time of year in which the plant was collected could determine its intended use. Some plants collected for culinary use as sprouts may be collected for their flowers or roots once mature, other plants become poisonous. It is important to know and understand the plants which are being collected.

The study of medicinal plants and substances through cultural knowledge is called ethnopharmacology.  It is not secret that many over the counter and prescription drugs find their roots in nature. Aspirin’s pain relieving ingredient has its history in willow bark, which could be steeped in water and drunk as a tea. Beano, another common drug and anti-flatulent, gets its effectiveness from an enzyme found in the fungus responsible for black mold. Surprisingly, around 50% of cancer treatment drugs approved in the last 30 years are derived either directly or indirectly from nature. The most common ailments treated by medicinal plants were those of the gastro-intestinal system. Today, many natural teas can be found in your local grocery store intended to treat the same issues and using some of the same plants, such as mint and ginger.

Although many native plants have fallen out of favor for culinary use, others have been elevated to such high status as to collect a hefty price tag at modern markets. In many parts of North America, spring brings an abundance of desirable wild foods including morel and chanterelle mushrooms, ramps (a wild leek with a mild garlicy onion flavor), and fiddleheads (fern sprouts).

Pennsylvania is fortunate to host an abundance of wild plants. Modern foragers, much like those of the past, look forward to Spring when nature’s bounty abounds. With the shortest day of the year now behind us, we can look forward to Spring and all it brings.

You can explore more Native American foodways at the State Museum of Pennsylvania’s booth at this year’s Pennsylvania Farm Show, taking place Jan 6-13, 2018 in Harrisburg, PA. The State Museum will host an exhibit space featuring information on native American foodways and the history of the development of agriculture in Pennsylvania. Prehistoric artifacts on display illustrate the transition for native groups from primarily hunters and gatherers to farmers.  The changes in stone tools including spear points and atlatl weights during the Transitional Period (2900 BP- 4850 BP) to stone hoes and pestles in the Woodland Period (1550 AD- 2900 BP) reflect this culture change. A corn grinding station utilizing stone tools allows visitors to experience the process used by native peoples. Our booth will be located opposite the carousel in the Main Exhibition Hall of the Farm Show Complex.  Mark your calendar and plan your visit to the 102nd Pennsylvania Farm Show (http://www.farmshow.pa.gov/Pages/default.aspx)

Fort Hunter: Where we are at now


Here we are, the Workshops in Archaeology and Thanksgiving are over and the Pennsylvania State Farm Show and Christmas season have begun. As we prepare our exhibit for the Farm Show in January 2018, the lab archaeologists and ever valued volunteers, have been hard at work processing the artifacts found at Fort Hunter this past field season. Today we are going to take a brief look at what happens to the artifacts once they come into the lab from the field and where we are in that process with this year’s artifacts.

As mentioned previously in this blog, a general rule of thumb for the time it will take to fully process artifacts in the lab is approximately seven days of lab work for each day of field work, depending on the quantity and types of artifacts found. With the help of our volunteers this time is cut down a bit, but it is still a lot of work and a long process.

The initial steps for processing any collection in the lab is to organize and record the provenience information from field bags through the preparation of a digital field bag inventory. The field bags are then organized by unit and level allowing for easy processing later on.

Once this is completed, the artifacts are laid out by bag on trays and the process of cleaning the artifacts through washing, dry brushing, or other conservation techniques begins. As can be seen above, we have already emptied a few bins of field bags and the image below shows some of the artifacts out and ready to be washed.

As the artifacts are cleaned and air dried, the next step in the process begins, labeling. Artifacts are labeled with the site number, in the case of Fort Hunter the site number is 36Da159, and the catalog number, which identifies the location where the artifact was found. Catalog numbers are determined based on the provenience information recorded from the field bags.

Once the artifacts are properly labeled, they are identified and bagged by type within each catalog number and then inventoried in a digital format, to make for easy lookup for research or exhibit creation.

Due to the great effort of our volunteers, it is possible to work on multiple steps of this process at one time. This allows us to process the artifacts in an efficient and effective manner. (For more information on how artifacts are processed in the state museum archaeology lab check out our previous blog, Behind the Scenes at The State Museum—Processing the Fort Hunter Collection: What happens after the field work is done?)

Currently in the archaeology lab, we have completed the initial organization and recordation of proveniences as well as the identification of catalog numbers for each provenience. Washing, labeling and identifying/bagging are currently occurring in the lab every day.

This year we are taking our processing one step further by attempting to mend, or put back together, prehistoric pottery fragments to see if we can identify one or more vessels. This has proven difficult as there are many very tiny pieces of pottery and many of the larger pieces do not fit back together, but some progress has been made as can be seen in the pictures below.

As we process the artifacts, it becomes more clear what types of artifacts are present in the collection and this year we seem to have an abundance of prehistoric artifacts such as stone waste flakes and tools, pottery and bone. This said, there are also numerous historic artifacts. Though very few of them date to the fort period they still help tell the story of the landscape. These artifacts include buttons, musket balls, butchered bone, nails of varying types and other architectural materials, historic ceramics and glass; as well as more modern artifacts such as plastic and Styrofoam.

 Here is a glimpse at some of the more notable artifacts we have uncovered from this year thus far:

Prehistoric artifacts:

 
Shell bead, possibly with incised markings on the top and bottom surfaces

 
Rim and neck sherds of Owasco cordmarked pottery type, dating to c. 1200 to 1300 AD (Ritchie 1965).

Additional rim, neck and body sherds from the Owasco tradition.



Unknown pottery type, vessel body fragments mended back together.

Vessel body sherd from an exterior and interior cord marked vessel, also mended together
.
Incised rim sherd fragment of a Shenks Ferry Tradition vessel.

Projectile points: top row: Madison type triangle point dates to the late Late Woodland Period (AD. 1450 - 1600.), second row down  Rossville-like point type, dates to the Middle Woodland Period (1,000 BP. – 2,100 BP.) third row down: Lehigh/ Koens-Crispin point type, dates to the early Transitional Period (4,350 BP. – 4,850 BP.), bottom row right: the large broadspear/ knife, dates to the Transitional/Late Archaic Period (4,350 BP. – 6,850 BP.) bottom left:  this point which could fall within Late Archaic through the Middle Woodland periods.
(Custer 2001, PHMC 2015, Ritchie 1971)

Historic period artifacts:

Tin glazed earthenware (left) and scratch blue salt glazed stoneware (right). Both fall within the French and Indian War time period, though all were found in mixed contexts.

Musket Balls of varying sizes and date ranges.


Gun Flint

Brass and pewter buttons dating around the late 18th and 19th centuries.


As usual, the fort at Fort Hunter remains elusive, but each year we find little hints of its existence through artifacts. We continue to learn more and more about the landscape and how human occupation has impacted the land through the thousands of years of use that we have been able to identify through our excavations. We hope you have enjoyed this update on what is happening to the artifacts found at Fort Hunter during the 2017 field season and we wish you all a wonderful and safe holiday season!
