History beneath Portsmouth Middle School

Last year, I got a call in my office from Detective Timothy Cashman, the Resource Officer at the Portsmouth Middle School.  During construction on the historic Portsmouth Middle School, various glass bottles were recovered by interested teachers and staff.  Before the original Middle School building was built in 1930, this area of Portsmouth next to South Mill Pond was used as a bottle dump by locals.  

These unbroken bottles are a useful resource for future archaeological comparison, as their shape, size, and makers' marks are all known.  When we find smaller pieces or shards of broken bottles in archaeological excavations, we may be able to identify those fragments by just a few visible letters upon comparison with these unbroken bottles.  

Some of the bottles had pretty interesting histories.  Interns and volunteers have done research on the bottles found at the middle school and their histories will be on display in a new case in the main hallway.  Next time you get called to the principal's office, be sure to take a look.  Here are just a couple!

A Burr's ad from 1868
This Burr’s Patent Nursing Bottle dates to the 1870s. Archaeologists have recovered pottery vessels for feeding infants that date to around 1500 BC.  Glass nursing bottles became common in the United States by the late 1700s. By the 19th century, Americans' interest in infant health had generated an increase in bottle feeding infants and the first nursing bottle patent was issued in 1841.  A glass bottle like this one would have been accompanied with a mouthpiece attached to a tube within the bottle.

A Curtice Brothers ad from 1925
These are two ketchup bottles from the early 20th century.  The Curtice Brothers Preservers Company bottle on the left would have contained Simeon and Edgar Curtice's Blue Label Tomato Ketchup.   

A Heinz bottle is on the right.  This is an early Heinz Ketchup bottle from between 1911 and 1919, looking fairly similar to the octagonal bottles you can still buy today.  

Heinz Ketchup was first sold in 1876 and has consistently been packaged in clear bottles, in an effort to showcase the quality and purity of the ketchup.  This was an early focus of the Heinz Company, as they generated debate over the use of benzoates in ketchup.  The benzoate debate led to decline in the popularity of other ketchups, allowing Heinz Ketchup sales to rise.
