Geologically the headwaters of this stream lie in the horizon 

 of the granites and gneisses. It flows across the Trenton group 

 and Hudson river shales. 



Discharge measurements of Sauquoit creel-. This station is at 

 a dam which is the properly of the New York Mills, used to 

 operate an extensive cotton mill. The dam is of earth, with timber 

 facing, having a spillway 105.8 feet in length. The following 

 cut shows cross-section and longitudinal profile of this dam in 

 comparison with Bazin's series No. 175 :

 at the New York Mills, in comparison with Bazin s series No. 175. 



When this station was established in the fall of 1898 the dam 

 was watertight and leakage consequently neglected, but the state- 

 ment is made that in May, 1900. the leakage was found to be 5.6 

 cubic feet per second and the station was accordingly abandoned 

 in October. 1900. The flow has been computed, using Bazin's series 

 No. 175. for which reference is made to the paper On the Flow of 

 Water Over Dams. 



Geologically this stream lies in the horizon of the Hamilton 

 shales, crossing the Helderberg and Balina groups. 



Discharge measurements of Oriskany creek. This station is 

 located at the canal feeder timber dam at Oriskany, with a crest 

 length of 214 feet. The profile is irregular and has been divided 

 into three sections to facilitate computation. The dam is about 

 four feet in hight. A scdion is shown in the following cut.
