"Though the idea of twin lights at Plymouth seemed an excellent distinction from a single navigation light shown at Barnstable harbor in the vicinity, they proved not entirely advantageous and a sea captain blamed them for causing his shipwreck. He had seen the light from only one tower and identified it with confidence as the Barnstable light; apparently, from a particular direction one tower hid the other. But local prejudice in favor of retaining the twin lights as a distinction prevailed until 1924 when, at last, opposition ceased to the recommendation which the Lighthouse Board expressed frequently that a single light would be preferable." It seems quite likely that the compass card bears one of the very few surviving contemporary representations of the first Gurnet Light in Plymouth Bay. A search of the archives of the historical societies in Plymouth, Boston, and Worcester and the files of the U.S. National Archives has failed to reveal any illustration of this famous lighthouse. Quite by coincidence, the name of Benjamin Warren was discovered among the entries of the day books of Paul Revere, the famous patriot, silversmith, and engraver. The entry[117] (fig. 63) appears as follows: 1786 March 13. Benjm Warren Dr. Plimouth To printing one hundred Compass Cards 0-18-0. Whether the compass card on the Warren instrument was produced by Revere is difficult to determine. Authorities on Revere's engravings agree that it could have been engraved by Revere but are unable to state it positively. It has been suggested that the entry in Revere's day book indicates that he merely printed the compass cards for Warren and that he did not engrave a plate. The charge for the work bears out this supposition; and furthermore, Revere's bills seemed to make a definite distinction between the engraving of plates and actual prints. Whether or not Revere was responsible for making the original engraving remains to be determined, but it is very probable that he printed the compass card of the instrument in the Streeter Collection of Weights and Measures at Yale.

Burnap was born in Coventry in 1759 and served an apprenticeship with Thomas Harland, clockmaker of Norwich. In about 1780 Burnap opened his own establishment, where he combined the crafts of clockmaking, cabinetmaking, and engraving of brass, in all of which he was greatly skilled. One of his apprentices was Eli Terry, who later achieved fame in the craft in his own right.[118]
