Verplanck COvin's report on the survey OF
the Adirondacks Just submitted to the Legislature at
Albany announces the result OF last seasons work.

the end of 1872 recorded in the previous repor the
Adirondack Survey rrangulation was slightly connected
with the United States Coast-Suryey work on Lake
Champlain by a few measurements from Crown Point
lighthouse There was then measured base line for
the survey This required the first attention OF the sur
veying party 1873. Two great primary tranges OF
Mount Hurricane and Bald Peak we're constructed the
base lines being the distances between lighthouses on
Lake Champlan, furnished to Mr.. Coyin by the
United States CossSurvey, and which had been deter
mined within fraction OF o metre The astronomical
co0rdnates of the different lighthouses, &c. were also
furnished, and have afforded the basis for trigon-
ometrical computation OF the true meridians and
parallels OF interior stations. The great length
OF the base lines adopted, the first being
miles and the second than H. and the consequent
size of the primary tranges makes the plotting OF the
angles upon the draft chart extremely accurate the
different angles being carefully plotted by their chords
The primary angles are remarkably well conditioned In
