enough and in execution good enough to meet tests to which expert 
hydrographers may in the future put it, in view of the large property 
interests involved. 
To guard against the loss of the exact location of triangulated 
points, through malice or accident, many precautions have been 
taken. Stone monuments are set at all stations where a sufficient 
amount of digging can be done. In addition, many underground 
and surface marks relating to each station are of record at this office. 
The triangulation work will be useful for any large local surveys 
which may be made in the shore towns, and it would form a safe 
beginning of a general survey of the State. 
The integrity with which Mr. Bramiey prosecuted his work is 
apparent. Mr. R. G. Pike, Jr., performed his duties as a recorder 
faithfully and accurately, and was of much service on many occasions 
by reason of his skill on the water. 
Two weeks of time were devoted to a reconnaissance between the 
Connecticut and Thames rivers. A description of the points selected 
as desirable for Commission use was sent to Assistant S. C. McCorkle, 
of the coast survey, and in charge of the triangulation work of the 
eastern section of the Sound resurvey. You have his assurance that 
so far as possible the request that such points be determined by him, 
will be complied with. 
METHOD OF LOCATING REQUIRED POINTS. 
The question is often asked, how does the Commission set a buoy 
at arequired point. Let it be assumed that the triangulation work 
is completed and plotted. The plotting consists in first making upon 
suitable paper what is termed a projection, which is simply a series of 
rectangles constructed to scale and whose sides are equal to one 
minute of latityde or longitude on the earth’s surface in this latitude. 
The geographical position of each triangulated point having been 
computed to the nearest hundredth of a second of latitude and longi- 
tude and the seconds and fractions thereof reduced to meters, these 
points are plotted in the proper position on the projection, and the 
map is ready to have sextant surveys plotted on it, or a layout of lots 
made on it. Suppose that we wish to set a buoy ata point on the 
Sound identical with a point on the map. The first operation is to 
place the center of a three-armed protractor over the point on the map. 
Next three triangulation points or stations are selected which have 
relative positions to the required point such as to produce a well
