station, comparable results rnay still be obtained. The following 

 are the flows at the two stations in cubic feet per second. The 

 apparent discrepancy at the upper station in October is explained 

 by the fact that the figures for that month are the means of only 

 the last sixteen days.

Lansing kill. This stream rises in the extreme northern part of 

 Oneida county, near Booneville, and 1 flows southerly to the village 

 of Leila, Avhere it enters the Mohawk river. The Lansing kill has 

 rapid descent, but thus far there is not much power developed 

 upon it.

 York from Pennsylvania in the southeastern corner of Cattarau-

 vania, and flows thence northwesterly to Salamanca, about thirty 

 miles in the State of Xew York; thence southwesterly for twenty

 and its tributaries within Xew York, at the point of leaving the 

 Staic. including Conewango creek, which joins the Allegheny river 

 in the State of Pennsylvania, is about 2100 square miles. Its 

 principal tributary from the north is Conewango creek, which 

 receives the outlet of Chautauqua lake and Cassadaga creek as

 also tributaries in Xew York, but none of these streams is of 

 special importance for water power. 



Chautauqua lake outlet. Ohailtanqna lake outlet receives drain-
