N.E." ^* The compass was protected by a pine cover that fitted 

 closely between the sights. The present location of this instrument 

 is not known, bat it appears to be the only known example by 

 William Greenough made of wood.®^ 



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.^**
