United States, under whose direction the stocking of the 

 river with fish is done, I asked his permission to furnish your 

 board with a copy of it, which was granted in the following 

 letter : — 



United States Commission of Fish and Fisheries, 

 Marshall McDonald, Commissioner, 



Washington, D. C, Nov. 30, i: 



Fred Mather, Esq., Cold Spring- Harbor, A^. V. 



Dear Mr. Mather : — I think it desirable that information of 

 general interest, prepared under the auspices of the United 

 States Fish Commission, should have as wide circulation as 

 practicable. The matter of your report should interest very 

 much the people of New York, and by being published early 

 would tend to awaken and increase interest in regard to the 

 protection and improvement of the salmon fisheries of the 

 Hudson. 



You are authorized therefore, to furnish a copy of the same 

 to the State Fishery Commission for their information, and 

 for printing if they so desire. 



Very truly yours, M. McDonald, Com'r. 



Col. M. McDona'd, Commissr of Fisheries, IVashijigtoji, D. C. 



Dear Sir : — In compliance with your order of July nth, 

 1888, I have made an examination of the Hudson river from 

 its mouth to the tributary trout streams of Warren County, 

 N. Y., with a view to learning the number of adult fish 

 captured during the last season ; the possibilities of taking 

 salmon eggs in sufficient numbers to warrant the establish- 

 ment of a temporary station for this purpose ; to also learn 

 the character of the small streams, and determine which 

 give promise of the best conditions for developing the 

 young fish during their river life ; and to ascertain the 

 height and character of the natural and artificial obstruction 

 to the ascent of salmon, and herewith forward my report 

 on this work.
