The exact date on this building is not known but it is probably late 18th century. Lydia Huntley Sigourney recalls attending school there as a four-year-old. In 1798 Consider Sterry opened an evening for instruction in writing and bookkeeping. He also taught mathematics, surveying without plotting, and laying out of lands. He taught sea-going men to obtain longitude at sea by lunar observations and how to find latitude by sun’s altitude. The only prerequisite for these courses was that the person be able to read.
Besides his work on lunar observations he and his brother published a book on mathematics with Nathan Daboll. He edited a system of practical navigation entitle “The Seaman’s Universal Daily Assistant” nearly 300 pages long. He also wrote several small treatises and political articles. All of this was attained with no training as he was completely self-taught.
Consider Sterry was born in 1761 and was the brother of Rev. John Sterry. In 1780 he married Sabra Park, daughter of Silas and Sarah (Ayer) Park of Preston. This wife died in 1794 and he married Mary (Norman) Hazen, a widow. He had 17 children.
