tor the entire contents, 81 $50 cubic
feet, which, computed at the rate OF Ga
cents the cubic foot, will give S54,46o'
for the expense OF construction.
Again, if we suppose the whole in,e-
terror distance of chains long and 20
deep to be excayated, we shall have to
remove 1854 cubic yards, which, COM
pnted at 10 cents the cubic yard, will
amount to Sl,564 10000; or, say, in
round numbers, that The mole completed
will cost $4,000 This object once eff
fected, the Chicago river, for five or SIX
miles N length, will afford enc OF the
finest and most secure harbors in he
world; for here vessels drawing from
Is 10 90 feet OF water may ride perfectly
secure from the destructive effects of
storms and tempests. Ia locating this
projected mole, on The sketch of the Var
Dor, the undersigned have been govern
ed by the direction OF ~ prevailing
winds on tina Lake, and Consequently to
secure Its entrance fromthe severity OF
those winds, have given it the oblique
direction therein shewn.
9TH. The probable eRienSe Of con-
strUction Including The different routes
designated on thehtat
Inc commissioners will be aware, that
in the estimates here pRsented Of the
probable expense OF constructing the
contemplated canal, cons derlng the pre-
sent stage of operations, Iierely approxl-
male values are TO be SD opposed; for a6
soiutc correctness canno, be expected,
even alter me final location, nor until it
shall have been entirely completed.--
However, the dpdersigned, in obtaining
these results, have duly compared and
dellherated on boz the propitious and
adverse features which their operations
and cursory examination of the country
have presented 10 them III relation 10 the
object in view, aud have thence drawn
The data used in their computations.
From the preceding Investigations, we
obtain, for The first route, as follows:

For the second roa&e. supposiog The

be tho same as in the above, there will
remain to be dcducled, from the net
amount there shewn, the following sums,

For the third route, making the same

will remain to be deducted, from The cs.
