where he was associated with the engraving firm of Draper, 

 Murray & Fairman. 



At the end of the 18th century Samuel Emery was making 

 mathematical instruments in Salem, at the same time that John 

 Jayne was engaged in the same work in that community. ^^ 



John Potter of Brookfield, Massachusetts, produced surveying 

 instruments in the last quarter of the 18th century. A graphom- 

 eter signed with his name and dated 1785 is in the collection 

 of the firm of W. & L. E. Gurley in Troy, New York. 



Rhode Island 



One of the earliest and most important of the instrument makers 

 of Rhode Island was Benjamin King (1707-1786), of Newport. 

 He was the son of Capt. Samuel King of Salem, Massachusetts, 

 where he was born and baptized on March 13, 1707. He was a 

 brother of Daniel King of Salem. Benjamin eventually moved 

 to Newport, where he married Mary Hagger in July 1742. They 

 had four children: Benjamin, Mehitable, Samuel, and Mary. 

 He established himself as a respectable businessman in the com- 

 munity, and in 1759 or 1760 he became the senior partner in the 

 importing and retailing firm of King & Hagger, "near the sign 

 of Mr. Pitt," dealing in general merchandise, mathematical and 

 nautical instruments, and stationery. William Hagger was 

 probably the junior partner, and may have been King's brother- 

 in-law. King began making his own instruments for sale, sur- 

 viving examples dated as early as 1762. The partnership was 

 dissolved early in the 1760's. In 1766 Benjamin King was 

 importing, making, and selling quadrants and other instruments 

 "At the Sign of the Mathematical Instruments" next to the 

 Golden Eagle on Thames Street. His son Samuel King occupied 

 the same premises, where he dealt in paints and artists supplies. 



When the British occupied Newport, King moved to North 

 Kingstown, but he returned after the British vacated the city. 

 He was 79 when he died in 1786, and his son Samuel King succeeded 

 him in business.^^ 



William Guyse Hagger (c. 1744-1 830.?), born in Newport, is be- 

 lieved to have been the son of William Hagar and Mary Knowlton. 

 He was a quadrant maker (see fig. 21). In 1774 he headed ahouse-
