enee shows that canal water supplies must be made ample, as 

 otherwise a shortage will result sooner or later. 



In a paper on Mi Enlarged Waterway Between the Great 

 Lakes and the Atlantic Seaboard, by William Pierson Judson, 

 the water supply of the summit level of the Oswego-Mohawk- 

 Hudson route is discussed at length. Mr Judson considers that 

 it would be entirely proper to take whatever deficiency there 

 might be from the headwaters of the Black river", reservoirs in 

 addition to those now existing being constructed on the Beaver 

 and Moose rivers, tributary to the Black, for the purpose of fur- 

 nishing this water. He recognizes that the item of adequate 

 water supply for such a canal is vital, and states that if surveys 

 and thorough investigations were to show that the demand for

water for such a canal is beyond the capacity of the sources of 

 supply, then the Oswego-Mohawk-Hudson route would be shown 

 to be impracticable, although as an alternative proposition he 

 states that it would be entirely practicable to supply the summit 

 level of such a canal from Lake Erie. This, it is pointed out, 

 can be accomplished by a feeder branch taken from the present 

 Erie canal near Macedon, 12 miles west of Newark, where the 

 Erie canal is now 35 feet above the Rome level. The proposed 

 feeder, instead of stepping down, as does the Erie canal, can be 

 swung off to the south on higher ground at the necessary eleva- 

 tion, passing along the south side of the Clyde river and cross- 

 ing the Seneca river near the Cayuga Lake outlet. Seneca river 

 is narrowest here, and the feeder could be carried across it in an 

 open trunk on a 40 to 50 foot trestle about '2 miles long. 



A canal on the Oswego-Mohawk-Hudson route 28 to 30 feet in 

 depth, with corresponding surface and bottom dimensions, will 

 probably absorb nil available water of central New York, as well 

 as a considerable portion of Black river. The waterpowers on
