ing streams, lakes and ponds, the reaction of fishes to pollution, 

 the distribution of the various species within and outside the 

 limits of the waterslieds, the contribution to educational work of 

 the colored plates of fishes and relevant data which will be 

 comi)iled eventually in a volume entitled "Fishes of New York 

 State." 



One most important result is tlie esta])lishment of cooperative 

 relationships witli educational institutions in the State, a most 

 helpful relationship in adapting science to practice. 



It is hopefully expected the surveys will cover eventually the 



19 watersheds in the State. Each presents its own more or less 

 ])eculiar and technical problems, some of which must be studied 

 in the follow-up program intensively a long time. 



Papers by Specialists. — The data collected in the several lines 

 of inquiry are presented in the following sections dealing with : 



(1) Stocking policy for the Erie-Niagara system. 



(2) A preliminary report on the joint survey of Lake Erie. 



(3) Chemical investigation of the Erie-Niagara watershed. 



(4) The biological investigations of pollution. 



(5) Studies upon the fish blood and its relation to water 

 pollution. 



(6) Fishes of the Erie-Niagara watershed. 



(7) The food of certain fishes of the Lake Erie drainage basin.
