es, till at length it was brought within the compass of
both plans and sections, and exhibited to your Committee about the latter
end of January, 1819.

From which data, and what more Mr. Palmer was able to give Mr. Telford
from his own observations, your Committee requested Mr. Telford to give
his estimates of the most advantageous manner of communicating this place
with the navigable part of the river Ouse at Acaster Sailby, (this being
at that time the point fixed on at the lower end of the line) either by a
double Rail-way only, or by a double Rail-way to the Brook Crimple, and
hence by a Canal to Acaster Sailby, taking the water from this brook as a
supply, and forward from Knaresbro' to Pateley-bridge, by a single
Rail-way, with passing places.

The separate expenses of each, as furnished by Mr. Telford, are below:--

MR. TELFORD'S ESTIMATE.
Pounds
4.75 miles, with 116 From the lowest part 15,794
feet fall. of the Bond End, at
the bottom of the
High-Street, in
Knaresbro', to the
Brook Crimple, on
Ribston-Green, a
double Railway
9m. 1140 yds. with 82 From the Crimple 68,628
feet fall. Brook to Acaster
Sailby, a Canal
Add Ten per Cent. for 8,442
Contingencies
92,864
20 m. 142 yds. with From the same point 60,000
198 feet fall. in Knaresbro' to
Acaster Sailby, by a
double Rail-way
14.75 m. with a fall From the same point 38,830
of 11 feet per mile. in Knaresbro' to
Pateley-Bridge, with
Passing-places

In the foregoing estimates Mr. Telford has considered the Canal, with its
locks and bridges, as suitable for the Humber Sloops, and the Rail-way
sufficiently strong to admit of one ton and a half being carried by one
waggon.

When it was originally intended for the lower end of the line to commence
at Acaster Sailby, it was unknown to your Committee that an Act of
Parliament existed, levying duties on merchandise on the River Ouse,
after the same had passed the Wharfe mouth towards York; for the better
information of the public, we in
