ASSEMBLY OF THE GAGE 
Before assembly the various components of the gage are prepared as 
follows: an annealed copper-tube single-conductor cable is filled with wax, 
using a technique developed at the Taylor Model Basin (18). The outer sur- 
face at one end of this cable, as well as the inner surface of the brass tube 
to which it will be soldered, are tinned. The lateral surface of the cover 
is also tinned to prepare it for soldering to the pan. Pure orange shellac 
erystals are heated until they just melt; then thin coats of shellac are ap- 
plied to the inside surface of the cover and pan, as well as to both surfaces
