In 1899 the writer was consulting engineer to the Canal Com- 

 mittee, and added very greatly to his knowledge of the hydrology 

 of the State. 



In 1902 he was a member of the Water Storage Commission of 

 Xew York and extensively considered a number of storage and 

 power projects in the State. 



Since 1900 he has been in general practice as consulting 

 engineer, and during this time has been employed on power 

 projects in this and other States, until at the present time there 

 is hardly a phase of power development or water storage that has 

 not at some time been before him for consideration. 



During all this time he has been gathering information in 

 regard to water power and allied subjects in New York. There is, 

 however, still much to be learned, as, aside from the studies of 

 the writer, very little has been done in the State, outside of the 

 City of Xew York. 



The elevations of points above tidewater have been compiled 

 from all available sources of information, such as the Dictionary 

 of Altitudes in the United States, Bulletin No. 76 of the United 

 States Geological Survey ; the reports of the New York State Sur- 

 vey and railway and canal profiles ; the topographic quadrangles 

 of the United States Geological Survey and the reports on the 

 water power of the United States, Tenth Census, as well as the 

 report of the Board of Engineers on Deep Waterways. Mr Free- 

 man's report on the Xew York water supply, together with the 

 report of the Merchants' Association, has been drawn upon in 

 discussing the water supply of New York city. 



It may be easily inferred that this report is not very even; 

 that is, the information is more completely developed on some 

 streams and on some subjects than on others. On the Genesee, 

 Oswego, Salmon, Black and Hudson rivers and their tributaries, 

 nnd on the Niagara river, the information is tolerably complete. 

 It is also fairly complete on some of the smaller streams, al- 

 though on the majority there is still a large amount of work to be 

 done, but on the streams of the southern section — Allegheny, Sus- 

 quehanna and Delaware rivers, with their tributaries — very little
