(a) It is supposed that the elevation here given by the E. & P. refers to 
a point somewhat higher than the present Depot. 
(b) We prefer to accept 1168/ as the elevation of Stoneboro’ instead of 
1170’ or 1171’ for several reasons. From Pittsburgh to Oil City by the 
line just followed we find a rise of 265’, while from Pittsburgh direct to 
Oil City by the A. Valley Railway levels well tested we have a rise of 
263’. There is an error of 2/ somewhere in the circuit. The L. 8. & M. 
S. levels are too high at Oil City when compared with the A V., the O. C. 
& A. R. and the A. & G. W.; they are too high again at Franklin, com- 
pared with the A. V. and A. & G. W.; too high at Salem Crossing, com- 
pared with the A. & G. W.; and too high at Jamestown, compared with 
the E. & P. We are not certain that the connecting link between N. 
Castle and Stoneboro’ shows precisely the difference in elevation between 
the Depot of the N. C. & B. V. at N. Castle and the Depot of the L. 8. & 
M.S. at Stoneboro. There might easily be a difference of two feet be- 
tween the Depots of the N. C. & F. and those of the other roads named. 
Our accepted level at Oil City appears to be a mean between the highest 
and lowest levels given wherever a check can be secured, and it therefore 
seems safe to adhere to it.

there appears to be but 3/ disagreement between the levels of the A & G. 
W. and the N. Y. and Erie, if we have taken our points correctly, and 
1393/ will be a fair mean between the two for the present depot.
