20 FIFTH REPORT OF SHELL FISH COMMISSIONERS 
EnPiieersavep On: 
To the Commissioners of Shell Fisheries of the State of Con- 
necticut : 
GENTLEMEN :—During the past seven months the demands 
for work which have been made on your Engineer and his two 
assistants have been such as to prevent an elaborate report of the 
details of the work accomplished. His controlling idea in con- 
ducting the work has been to make it accurate and complete. 
A large amount of work has been under consideration which 
could not by any possibility be forced to immediate completion; 
for much precise data pertinent to the work had to be prepared 
in advance, to be ready for immediate use, and this required 
many tedious mathematical computations. 
TRIANGULATION WORK. 
I have sought to eliminate from the surveys, as fast as oppor- 
tunity offered, all those weaker elements which were unavoidable 
in the beginning. With this end in view, seven signals, which 
were located by hydrographic methods, were last spring observed 
on with reference to conversion into triangulation stations. 
Thus were secured data for their exact geodetic determination, 
and other advantages incidental to triangulation methods. In 
addition to the above, six new positions were triangulated, three 
of which are near New Haven and three near Greenwich. 
Establishment of jurisdiction lines and developments incident to 
examination of lot records made these six stations essential. 
Twelve stations were occupied. Seven were determined by 
cuts. The observations occupied thirteen days in April and 
May. I made 849 pointings with the eight-inch theodets. Mr. 
R. G. Pike, Jr., was the recorder.
