remedy this difficulty by letting the canal boats

II brief description Of the device b. which
the results indicated arc to be attained will not
| be without interest to the reader At the point
above mentioned Ia mi!c and hall above a
quaduct brdge) deck has been constructed
90 the right Of the canal into which boats IL
tended to be lowered into the river are turned
aside. At he lower cod Of this dock is gate,
| through which the boats arc to be passed into
an Immense talk technically known ;: . "cas-
son" which has a water tight gate Ut a-c! cud.
The upper esd OF this tank forms watcr-tighs
joiot with the lover ccd Of the dock, aal by
opening the gates a boat is readily transferred
from the dock TO the tank, ai:er which the
gates are closed, and the tack or "caiss0n,"
with canal boat al, ~ Ia it, Is prepared TO
transport lls burden 10 the river. The tank Is
mounted on trucks IN such manrcraS 10 keep
it level, aad is let doEn to the river by nlcaus
of double track railroad, which runs cut into
the water FAR enough 10 slnk the tank cnIIrcy
below the surface in which position the boat
is H)atcd easily ont nto the rlgcr. Ibis tank
is let down and dfawa up b. means 81 turbine
wheel Of sixty eight horse over, which, how.
ever, would be wholly Inadequate for the pur-
pose, brt for the fact That the weight o: tic
tan; is b .i.acc! by that Of TWO great cars load
cd with rocks Which move on side tracks,
dcsceuGiug The iacu:i plane toward the rlV-
or as tic tank ascords from the river toward
the dock, aud vice versa. The t.at; is Kept
full OF wat2r in Ascending, and. a. cara!
boat Oh entering it, l.piac2S cxa>t!y It; own
weight Of water, the weight Of the tax and It's
contents remain inrara!lo, and Tie ba'a.ce
between it and the cl!s Oh the side tracks Is
thus constantly mqintaiacl. The tractioo Is
applied by means OF Immense wire cables,
witch pass over iron wheels Of great strength,
tie turti"c wheel merely furnishing poser
