" At Oak Orchard Creek, an aqueduct will be
necessary 200 feet in length ; and it may be con-
structed of stone abutments and piers supporting
a wooden superstructure, to be replaced hereafter,
perhaps, by one of stone or iron. The bat tont
tlt the creek, consisting of rock, is 23 1-2 feet
below the contemplated surface of the water in
the Canal. Good stone are here on the spot, and
two piers between the abutments, may he so
placed, as with them to afford three spaces of 50
feet by 23 for the passage of the water below.
This is the creek into which it is thought expe-
.dient to bt ing the upper floods of the Tonne-
ivanta : And when it is considered, that its bed is
smoo•h, rocky, and of considerable declivity, with
a perpendicular fall„-two chains below, of 25 feet,

Al•fmden part of this aqueduct, with the least pos-
sible diminution of the water-way, braces might
be introduced with one end resting on the stone-
work of the abutments and piers, and the other

across the spaces between. The expenee of this
