[1798?]. Folio, approx. 340pp. Boards lacking, leather spine partly perished, cracked and worn, first page of manuscript notes is detached. The names of both Jacob Scheetz and John Schuetz appear in the margins of the text, and the date '1798' is mentioned in some of the subject headers. Calculations are done in pounds. A faint rubber stamp appears in the lower margin on the first page: "Geo. H. Scheetz, General Merchandise, Kellers Church, PA, Feb. 10, 1904," presumably a descendant of the original owner.
The student scribe records definitions for several mathematical terms including interest, brokage [sic], compound interest, rebate or discount, equation of payments, barter, loss & gain, single fellowship, inverse proportion, double rule of three, fractions, vulgar fractions, arithmetical and geometrical progression, mensurating of superficies, etc. Many of the word problems relate to merchants, purchases or sales. Calculations and solutions are shown. There are small, neat illustrations in the geometry section. A nice example of an early American student exercise book. Item #63888
The owner was likely a member of the Scheetz family, immigrants to Bucks County, Pennsylvania in the 18th century. George H. Scheetz, whose stamp appears on the first page of the text was the grandson of George Scheetz (1785-1863) who settled in Kellers Church, Pennsylvania around 1820, and was a school teacher. Some family genealogies state that he had several brothers, including Johannes and Jacob.
