An instrument of considerable significance is another wooden surveyor's compass, in the collection of the Yale University Art Gallery. This compass (fig. 57) is made of rich brown San Domingo mahogany with sighting bars of boxwood. A mariner's card, set into the opening with a metal vernier scale, is in the usual form of the mariner's compass card of the 18th century; it is executed as a line engraving. A ship and the Boston harbor lighthouse are featured in the central medallion. On a riband encircling the medallion is the inscription "Made by ANDW. NEWELL East End of the MARKET BOSTON," Engraved in script at the southern tip of the star is the signature "N. Hurd Sct." Relatively little is known about Andrew Newell (1749-1798) except that he was a maker of mathematical instruments. An entry in the first Boston directory, in 1789, listed "Andrew Newell, instrument maker, 61 State Street." The directory of 1796 mentioned Newell as having a shop on the "East side of the Market," the address that appears on the surveying compass. Two years later the Boston directory listed Andrew Newell and Son, and in 1800 the listing included only the name of Joseph Newell, who may have been the son. Another mathematical instrument maker named Charles Newell may have been another son of Andrew Newell; his name does not appear in the city Directory until in the 19th century. An instrument with the signature "Newell & Son, Makers, East End of Faneuil Hall, Boston" is in the collection of the Bostonian Society. An important feature of the Newell instrument is the fact that the engraver of the compass card was Nathaniel Hurd (1729-1777), the peer of goldsmiths and engravers of the colonial period. This compass card is a previously unrecorded example of Hurd's work, and constitutes a work of art, making the compass a historic scientific instrument.[111] The compass was presented to the Yale University Art Gallery by a Yale alumnus, Mr. Henry G. Schiff of New York City. No other examples have thus far been found. _Aaron Breed_ Aaron Breed (1791-1861) is a relatively unknown maker of mathematical instruments who worked in Boston into the 19th century. He specialized in nautical, mathematical and optical instruments, with an address at 173 Broad Street, and another at No. 2 Rowe's Wharf, "At the Sign of the Quadrant." Breed made surveying instruments in brass and in wood. A brass instrument is in the Henry Ford Museum, and a wooden instrument is in the collection of Old Sturbridge Village. The latter is fashioned from walnut with an engraved compass card inscribed "Aaron Breed Boston." _Charles Thacher_ The name of Charles Thacher appears on the compass card of a wooden surveying compass (fig. 58) in the collection of the Mariners' Museum, Norfolk, Virginia. No record of this maker has been found, but the engraved compass card indicates that he probably worked in New England.
