My estimate of the value of the work, 1
think very liberal and more particularly so,
as it was designed to push the gradua-
tion and masonry to completion by the
coming fall.

I will here remark that the estimate for
the graduation and masonry above is taken
from that furnished you previous to the lei-
ting of the work, in which the road was di-
vided into sections, and each section esti-
mated separately. The work already let is
a fraction under the estimate.

GRADES, CURVATURES AND DISTANCES.

The distance from Blossburg, where this
road commences to its termination at the
State line, near Latvrenceville, is 95790",
miles. The total descent in that distance
is 355,56 feet, reckoning from the grade or
the road at its cornmencement to the termi-
nation of the same at the State line.

From Blossburg to Covington, a dis-
tance of5 miles, there is a descent of 149,43
feet, making considerably more than -1‘, pari
of the total descent in 1 of the distance.

The maximum inclination of the grade
line is 89.07 feet per mile and this extends
only 3737 feet, and occurs 1% miles below
Blossburg.

The average grade from Blossburg to
Covington, is 99.88 feet per mile. The
grade from Covington to the termination of
the road, varies from 5 to 95 feet per mile,
and averages 9.86 feet per mile.

The road being on an average descent of
13.73 feet per mile from its commencement
to its termination, will favor the expense of
transportation very much, and the grades
not being so great as to interfere with a re-
turn load of say § part of that taken down

are to be desired rather than to be regreted,
considering the great object in view, being
the transportation of coal.

The curvature on this road may be said
to be gent1e,the.re being no curve of a less
radius than 666 feet, and but a short dis-
tance, comparatively, at this rate. The
straightpart of the road is to the curved
part, as 7.10 nearly.

or THE MOTIVE rowan.

As it is designed to use steam by Loco-
motive Engines, for the motive power on
this road, I will take the result of experi-
ence in the application of this power, and
apply it to the grades and curvatures of
this road to show what may be done on it
in the way of transportation.

lst. It has bee n ascertained that the
grades are all descending lrom the coal
mines, and that the average of them is
13.73 feet per mile. ___ _ ’ v

9nd. That there is no curve of a less
radius on the road, than 666 feet.

3d. It has been proved that a locomotive
steam engine of 7% tons weight, including
water and fuel will draw 112.5 tons on a
level road, at a speed of nearly 19 miles
per hour. The traction exerted in this case
is therefore 1119.5 x 19 =1350lbs. This
traction is the measure of the adhesion, ex-
clusive of the engine and tender, of 19 tons
weight.

It has been also shown, by recent experi-
ment, that a locomotive engine of 8% tons
weight, will impel, on a level, a load of 911
tons gross, at the rate of 11% miles per hour,
thereby exerting a tractile power of 2399
lbs., besides the resistance of the engine
and tender.

If we consider, in the application which
I propose to make of the above results. that
a mean between them is the fair measure
of the power of the engine which will be
used on this road, we shall arrive at the
following useful efi'ects which may be pro-
duced :— '

It is known that the friction or resistance
on a level straight road, is about 5.},-
or per ton, lbs. 9.59
The resistance from curvature on

this road is estimated at 3-99
