Other documents in the same collection indicate that Greenough's business interests were substantial and not limited merely to the construction of instruments. On July 31, 1769, Greenough's name appeared on the Boston Citizens' Non-Importation Agreement. Subsequently, on December 14, 1774, there is Greenough's signed receipt, with the amount left blank, stating that he had "REC'D. of Capt. Thomas Godfrey the Sum of ---- in full for my Negro man Cuffes Shair in the Whaling Voige ----." [Illustration: Figure 42.--Brass surveying compass made by Thomas Greenough (1710-1785) of Boston. Compass face is mounted on main blade with two copper rivets. Screws for vanes and tripod mounting are hand cut, with wing nut ends. Sighting bars are 1/16 in. wide and 5-1/4 in. high; over-all length is 11-7/8 in. and diameter is 5-1/4 in. Owned by Greenough family of Boston.

Romaine of Middleboro, Massachusetts, in 1939 described a wooden surveying compass with its own hand-whittled tripod made of oak which bore a compass card inscribed "Made by William Greenough, Boston, N.E."[94] The compass was protected by a pine cover that fitted closely between the sights. The present location of this instrument is not known, but it appears to be the only known example by William Greenough made of wood.[95] [Illustration: Figure 43.--Wooden surveying compass, made and sold by Thomas Greenough. The instrument is made of gumwood and has a paper compass card; it is 13-1/4 in. long and has a diameter of 5-3/4 in. In collection of Franklin Institute, Philadelphia.] In the Greenough family at the present time is a brass surveying compass (fig. 42) of fine quality and of the period before or during the American Revolution. The dial is finely engraved with a Tudor rose at its center, and around it is the inscription "THOMAS GREENOUGH BOSTON Fecit." The compass face is mounted to the main blade with two copper rivets. The holding screws for the vane and tripod mounting are rather crudely hand cut with wing-nut ends.[96]
