Datum : Tide water at Philadelphia. 



This datum, however,is dependent upon the level of the eastern terminus or 

 Driftwood Junction with the Phil. & Krie II. R. But this is known to be too 

 low, and tlu'refore, the levels of the whole line are too low, and carry down 

 with them those of the Allegheny Valley Main Line, as stated in notes, to 

 Table ('CCI. 



Mr. Burgin's original level on the P. & E.R. R. at Driftwood was 788'. This Mr. 

 Wilson toolc for his datum level in the surveys of the Bennett's Branch Exten- 

 sion R. R. across to the Allegheny Valley R. R. Mr. Wilson's levels are given 

 in column 1. 



On the prt>file of the P. & E. R. R. used in Table CCXVI, the level of the point 

 of junction is called 795 (7 feet higher). Column 2 makes this first correction, 

 which helps to lift the Allegheny Valley levels a little, but not near enough. 



Column A is left blank for a future correction, when the levels of the P. & E. 

 R. R. are lifted, as they must be ; for, although they start about right at Sun- 

 bury, they are already about 20 feet too low at Williamsport by the Catawissa 

 R. R. (LXV), and by the Northern Central R. R. (CC) lists of levels; and feet 

 too low at Lock Haven by the Pennsylvania R. R. (XV) branch lists. At Em- 

 porium also they are 18 feet lower than the Buffalo, N. Y. & Phil. Railroad 

 (CCXIX). 



But even this 20 feet added to the previous 7' = 27' will not suffice to lift the 

 west end of this Bennett's Br. Ext. R. R. high enough to cancel the difference 

 at Franklin and Oil City. It is probable, however, that the whole residual 

 error lies on the Allegheny Valley R. R. line.
