XXV in. Butler Branch W. P. R. R. 



The levels on the Butler Branch Extension of the West Penn R. R. were fur- 

 nished by Mr. Antes Snyder, Euf^ineer, Sprinj^dalc, Allegheny County, Pa. 



There w an unexplained difference of 29.5 feet between the Butler Branch R. R. 

 grade and the West Penn R. R. grade at Freeport, where they ought to be the 

 same. 



Anotlier list was obtained from :Mr. .1. M. C. Creighton, differing very slightly 

 from Mr. Snyder's ; but still leaving an xuxexplained difference of 27 feet at Free- 

 port. 



The second column in the flr.st table gives Mr. Snyder's levels let dmvn 29>4 

 feet, and in the second table Mr. Creighton's levels let down 27 feet. 



The third column has seven feet added to reduce to mean Atlantic Ocean 

 Level. 



The datum of both taldes is called " Mid Tide" at Philadelphia, which would 

 require an addition of only o..;iil feet (instead of 7) to his original figures. See 

 foot note on page 64. But this "Mid-Tide" maybe a mistake for the "Mean 

 High Tide" of tlie Pennsylvania R. R. Company's datum and is so taken.
