costing more than four-fold more at the least
estimate. would not accommodate vessels of
one-third the capacity of those traversing
this route, and which could only partially
relieve, at the best, the pressing need Of
greater transportation facilities, while the
Champlain route would furnish capacity
sufficient to bear the whole product of the
West, and more, for, practically its capacity
is almost limitless.
Since the above was written | have re-
ceived the report which Immediately follows,
from Mr.. G. 7. Hall, the engineer, who has
been employed in making survey Of proposed
ship canal. As it gives full description OF
the canal from Whitehall to Fort Edward,
its size, locks, feed of water, ETC., together
with careful estimate of cost in detail,
commend it to the careful perusal Of all who
take any interest in this matter
WHITEHALL, N Y, Dec Is, 1874.
Hon. Alexander Barkley Canal Commissioner:
SIR-In accordance with your request, have the
honor to submit the following report and map Of
the preliminary survey for a ship canal from Lake
Champlain at Whitehall to the Hudson river at
Fort Edward.
SURVEY
On the 9th August / received instructions from
S. Il. Babcock, Esq, resident engineer, to proceed
to make at my earliest convenience, preliminary
survey Tor a snip canal and map thOreoi, from
whitehall to Port Edward. The engineer corps at
this place was at once organized for that purpose.
in connection with our regular duties attending
the Champlai IN canal enlargement and actual field
work was begun September lst. The transit line o!
the survey was assumed as the centre line OF the
proposed ship canal, and was begun at point in
mid stream of Wood creek at right angles to the
lower mitresil Of the lowest Of the combined LOCKS
at Whitehall. The object gained thereby, is to
utilize and follow, as nesrly as practicable, the
channel OF Wood creek, reducing the elevation OF
the Whitehall level - feet from the present oleya-
tion of the " ive-mile level" Of the Champ!ain
canal, neces-itating the construction OF but one
lock with lit oil - ieet in the place OF three
combined locks, now in use, with total liitage Of
IS feet The general direction Of the line Of surrey
