east as Old Saybrook. The number of buoys set was 418. Buoys 
-surveyed 493. Rocks, trees, and drill holes, whose position was 
determined with the sextant, 12. Total positions determined by sex- 
tants, 923. 
The noticeable results of these surveys are the opening to cultiva- 
tion (with assured location) of some thousands of acres of new ground, 
the completion of the surveys of lots off the town of Greenwich, the 
mapping of the Roton Point and Fish Island natural beds, the map- 
ping of abandoned but legal claims south of Smith’s Island, and the 
mapping of lots off Stamford and Darien. 
The preparations made for buoying out the grounds sold were very 
satisfactory, and relieved me of much detail work. The plan of ar- 
ranging the notes for field use was as follows: A tracing ona scale 
of 1 in 20,000, showing the lots off one or more towns, so that the 
tracing did not exceed 24 inches in width, thus securing it against 
being unwieldly in the wind, was made. Beginning with the number 
I, the corners of the lots, and intermediate points on their sides 
where desirable, were numerically numbered with black figures, fol- 
lowing each other in some natural order of arrangement. At points 
where buoys had been previously set or surveyed, their number was 
placed in red ink. Note books, 4 by 634 inches in size, and con- 
taining 160 pages, were bought, and the successive pages stamped 
with large black figures, and corresponding buoy numbers entered in 
red, so far as they occur. ‘The proper sextant angles were taken from 
the working maps of the office and duly entered in the note books. 
These books have printed on their covers, in full and plain letters, 
with a hand-stamp, the name of the town or towns for which they 
contain notes. 
The tracings are plainly lettered at theirends. They are carried in 
a tin case which contains a spring roller. As the case is so arranged 
as to allow the tracings to be readily taken out and put back, one case 
suffices for each party in the field. 
The advantages of this system are obvious. It saves much labor in 
looking up material. If buoy setting is to be done off any town we 
have simply to take the book and tracing for that town, and we are 
sure to have the requisite data with us. As new sales are made, the 
tracings are added to, corners numbered, and angles for the corners 
entered in these note, or angle, books. 
Every buoy set or surveyed receives a number, and this number 
always appears in red ink on your maps and tracings. When a loca- 
tion receives a red number it always retains that number, unless there 
is reason to change the angles.
