Only one complete instrument produced by Joseph Halsy appears to have survived--an especially fine wooden surveyors compass (fig. 39) in the collection of the New Hampshire Historical Society. It is made of maple. The compass card, probably the most interesting of any found in the wooden instruments, is hand-colored in black, blue, red, and gold. A fleur-de-lis marks the North point, and triangular pointers indicate the other compass directions. Inside the pointers are crudely painted female figures representing the seven arts: NW, Grammar; W, Logick; SW, Geometry; S, Arithmetick; SE, Astronomy; E, Rhetorick; and NE, Musick. Within a medallion at the center of the compass card is depicted a sailing vessel at sea; surrounding the medallion is a riband inscribed "Made and Sold by JOSEPH HALSY Boston--New England."[86] Another, but much less elaborate, compass card used by Joseph Halsy, is an engraved example (fig. 40) found glued in Thomas Paine's own manuscript copy of Charles Morton's _Compendium Physicae_, which is preserved in the collection of the Massachusetts Historical Society. John Halsy (fl. 1700-1750), also a mathematical instrument maker, had a shop on Green Street, in Boston, according to the Record Commissioner's "Report of the City of Boston." He was married on December 10, 1700, by the Reverend Cotton Mather. He probably was a brother of Joseph Halsy who worked in the same period. John Halsy subsequently abandoned his instrument-making business to become a pirate. He went out to Madagascar, where it is reported that he died in his own bed. He was buried with the rites of the Church of England in his own watermelon patch.
