Dr. Beau : I must apologize for the leugth of this 

 paper, but where it is possible I will omit such portions 

 as may be practicable. It has been parti}- dictated to 

 a stenographer and partly written in longhaud, and I 

 have had no time to revise it. I think you will over- 

 look the length of the paper, and allow me to do the 

 best I can to give you the essential points without 

 taking up too much time. It is an interesting paper, 

 and especially so to us, because it refers incidentally 

 to the pond method of rearing trout by means of natu- 

 ral food, that is, food which is supplied in the pond 

 itself; and it is interesting for another reason, which 

 is, that a Frenchman of high repute, a man in the first 

 rank of fish culture in Paris, has succeeded in raising 

 profitably as a commercial venture the California Sal- 

 mon in ponds in France ; secondl}^, he has secured the 

 reproduction of that species without its ever having 

 gone to salt water, and he says that after five genera- 

 tions in fresh water, the spawning is as ample as it 

 was at the beginning. He says, furthermore, that the 

 mortality among the females after spawning is much 

 less than we know it to be in the natural condition of 

 affairs in the Western rivers. It seems to me these 

 things are matters of much importance to us, and on 

 that account I hope 3'ou will bear with me if I do 

 speak at some length. 



Dr. Jousset de Bellesme is a man of the highest 

 rank as a fish culturist, the director of the Aquarium 

 of the Trocadero in Paris, where, in a small space, a 

 good many problems in the rearing of the salmonidcE^ 

 especially introduced sahuoiiidcv^ have been success- 

 fully carried out. I want to say further that my 

 impressions of the results obtained by Dr. Jousset de 

 Bellesme are drawn from personal observation, for I 

 had the pleasure of seeing what he accomplished in the 

 Trocadero Aquarium, and I am sure that nowhere else 

 in the world is the California Salmon reared as sue-
