III to be begun with raw recruits, whose drilling
must be paid for. Nor does the government gain
even the amount Of their pay, for they are enlisted
solely FOR this service, and would not be employed
ifnot used by the survey
Is. A list of the observations Of every kind, of
the Typographical maps and Typographical charts,
made in the progress of the coast survey, was
given by this department up 10 January, is4O,
(Senate executive document No. &c, thirtieth
Congress, second SESSION. The following alb
stract will show the Increase up to the first of the
present year, as far as the results have yet been
reported to the Office Of the survey, viz:

The following may be considered as among the
most prominent developments made ON our coast,
most Of them being real discoveries. They refer
necessarily to the photography, since determine
tons made on land, though Of previously UNI
known positions or distances, not thus termed.
Without the land work Of the survey, these dis
coveres would either not have been made ut all,
or else have been very imperfectly developed.
/. Gedney's channel into New York bay, hav-
ing two feet more water in it than the old channel
Had the true depth Of water in this channel
been known in l718, the French feet, under
Count D 'Estaing, would have passed into the bay
and taken the assembled British vessels. 1t is
urobable, from comparing the old and new charts,
fhnx this channel then existed.
2. Biake's channel into the Delaware; open
when the Eastern channel is filed with ice.
This discovery has already developed the re-
sources Of that part of the State of Delaware in
remarkable way

1896 six miles north of the old Nantucket South
Shoals
This shoal lies in the track of all vessels be-

one fourteen and half miles from land, and hav-
inc but ten feet of water on it, not marked On any

| 10. The remarkable increase Of Sandy Hook,
which has been traced from the surveys of the to-
biographical engineers and Of the coast surveys.
IL. The changes in the Delaware near the Pea
patch. -.
Great and Little Choptank, in the Chesapeake
i3 -Four shoals in the main ship channel over
the Nantucket shoals.
