Colonel Hnina's Project for Removing the
FInts and Improving tho IEnrbor.


The project submitted by Colonel Peter G. IIa n,
r the improvement and reclamation of tho POto-
m Flats, has been approved by the CHIEF OF
Engineers and Secretary OF War, and the work
will begin during the coming month. Colonel
linins describes the work as follows: "Thrce
Objects arc to be accomplished by the proposed
Improvement: The improvement OF navigation,
the establishment OF harLor lines, and the raising
Of the fats. The first Of these objects is to be &c.
complished by dredging a channel from Easby's
Point, near Georgetown, to near Giesboro' Point,
below the arsenal, and from GiesOord Point to
LGnl Bridge In the Washington Cnannel OF such
width anu depth ms will accommodate the largest
class Of vessels that can reach Giesboro' Point. A
depth of twenty feet at low tide will enable vessels
draw ing twonty. two feet to reach Georgetown or
Washington, and this depth is believed to be
ample.
THE RAisiSG OF THE FLATS

Of Fourteenth street will contract the tidal com
partment Of the river, and render 1t necessary to
give such width 70 the Georgetown Charhel rs
Will provide for the Increased dischaFge; The

than 2j,O00 square feet, which Is little more than
the area of the two cnannel, combined. High,

ing the project let us divide the flats into three
| sections.
THE FIRST SECTION
to be that portion lying between Easby's Point
and the sewer canal; the second or middle Sec
ton, that lying between this sewer canal and Long
Bridge; tie third land last section, that lying beLw
Long Bridge. The areas to be reclaimed ure us
| follows: Area above Long Bridge 420 acres, of
which about 1877 acres will be occupied by lakes,
determined. Area below the bridge. $50 acres.
Total area to be reclaimed $50 acres. The amount
OF material required to I'LL each section to the re-
| Quired grade, including the emhnnkment in sec
ton g. is follows: Section 1896 140 cubic yards;
section 1905 G3 cubic yards; section Q, 466i4j5
cubic yards; total l., ,6jS cubic yards. He es-
Inmates the total cost of tho work at 80 and
proposes to do the work by contract. He suggests,
cubic foot for dredging and depositing material is
too low.
