Georgetown Harbor ana Channel

and the Long Bridge, and to Inconvenience

prlation of March 9, 1870.
In March, 1882, survey Of tho Virginia
channel OF the river was made, and II was

The Coal Trade of Georgetown,

Ing points. First, about midway between

nearly opposite Giesboro, Point, whore .dredg:

1t was found that tho appropriation OF $780,,
for the work, and In the aproicct" OF April O,
1882, 1t was recommended that q part Of tho
| amount OF $4,000 reserved for Georgetown
harbor and channel, from the appropriation
of March Q, 1881, be applied to dredging.
This appropriation OF March 8, 1881, was not
specially DESIGNATED for any part Of the work
| having been made for improving tho harbors
and channels at Washington and George
town.
cations were issued under date OF April a,
1882, and proposals were received and opened
on Wednesday, May 10, 1882.
The contract was awarded to the lowest bid
der uhe Potomac Dredge Company, OF Wash

Tho contract provided for dredging to o
| points above mentioned.
Work under this contract was commenced at
the bar next below Easby's June ID. 1882, and
was In progress at the close OF the fiscal year.
