the highway by a stone culvert about three feet in width and four 
feet high, so that it makes no material difference to either town 
whether the monument is placed on the west or east bank. It 
will now be easy to make any rectification of the position of this. 
monument which may be desired. 
April 13 and 14, the initial point of the meridian section of the 
boundary line between Fairfield and Bridgeport, was determined. 
Owing to changes in the creek which forms the boundary, the 
position of the point was, in 1881, left subject to an investigation 
to be made by Mr. H. G. Scofield, City Engineer of Bridgeport. 
Mr. Scofield visited with me the point which he selected as a 
result of his labor, and which the Selectmen had approved. It 
appears that ayeargago a tide mill was located near the mouth of 
Ash Creek. In order to make navigation possible up to this mill 
the old channel was walled up so as to confine the water and 
increase its depth. ‘The mill has been gone many years and the 
old walls are in good part buried under the shifting sands. The 
point selected is midway of these old walls, and may be recovered 
by reference to data on file in the horizontal angle books. 
It was not possible to get a satisfactory three point position at 
either one of these town boundary points. ‘The theodolite was 
therefore set up 830.8 feet from the Greenwich line, and 1,535 
feet from the Fairfield line. In each case an angle was turned 
from a suitable triangulation station to the point sought, and the 
distance accurately measured with a steel tape. 
REDUCTION OF SOUNDINGS. 
To secure uniformity in the reduction of soundings to mean 
low water level, I have prepared a table giving the rise and fall of 
the tide for each half hour. The table is prepared for eleven 
places between the Connecticut River and Great Captain’s Island 
Lighthouse. ‘These constants algebraically added to the tides at 
New London, as given in the U. S. Coast and Geodetic Survey 
Tide Tables, give the required results. 
BUOY WORK. 
The number of buoys set during the year is 351; buoys sur- 
veyed, 110; total positions determined, 461. The greater part 
of this work was done by Mr. D. C. Sanford.
