88 ' SHELL-FISH COMMISSIONERS’ REPORT. [Jan., 
detail which appears has been reduced from maps which are on a 
large scale. In other words, we have more definite information 
about many of the pieces than is indicated by this map. Where 
the separate ownerships are so small as to become decidedly dimin- 
utive by the great reduction, no attempt has been made to show 
them. I do not claim an accurate location of the natural beds. 
The Stratford bed conforms to my present idea of its position and 
extent. The location of the other natural beds I deduced from a 
conversation with Messrs. C. W. Bell, C. W. Hoyt, Martin Prior, 
EK. F. Lockwood, and C. J. Nash. 
The triangulation sketch speaks for itself. 
The town meridian lines will doubtless eb given at length in 
your Report, and it will not be necessary for me to say anything 
further upon the subject. 
THE SURVEY MADE BY THE COMMISSIONERS. 
The triangulation and survey made the past season extends from 
the Connecticut River to Sachem’s Head, an air-line distance of 
twenty miles. 
The points which have been located by triangulation are twenty- 
four in number. The angles are concluded at four of the stations 
which are used in the connected chain of triangles. The signals 
erected are from sixteen to twenty-three feet in height. The mast 
is in most cases a stick three by four inches in size. The braces, 
four in number, and each secured by a four-inch spike, are twelve 
feet in length, four inches wide, and two inches thick. An inch 
board is driven at the foot of each brace. Thus the signal is made 
permanent. Unless they ‘excite the cupidity of the surrounding 
inhabitants,” they will stand a long time. The black and white 
cambric flags used are six feet long. At each of these points a 
five-inch flower pot is buried about eighteen inches below the sur- 
face, and a thorough description of the exact triangulated point is 
made, from holes drilled in adjacent rocks or boulders, or from 
suitable objects which give promise of permanence. For the 
underground mark I recommend a suitably-inscribed piece of vitri- 
fied earthen ware. 
For use in buoying, I recommend that the signais be boarded 
up and whitewashed. We thus have a cheap but probably success- 
ful sextant point. I ask that you recommend such legislation as 
will cause these signals to be duly respected.
