the corners of the original 
District, as well as some other 
points. The work was done 
by Mr C. H. Sinclair, of the 
United States Coast and Geo- 
detic Survey. To his courtesy 
and that of the Coast Survey 
office I am indebted for the 
following facts respecting the 
boundary line. The District. 
is not an exact square or 
spherical quadrilateral. Its 
distortion, much exaggerated, 
is shown in figure 1. The 
northern point is not exactly 
north of the southern point, but bears 5’ 19”.7 west of north of it.
