Mr. Cheney : I do not know who the foreigner is 

 that Mr. Mather referred to, bnt it may be Mr. F. 

 Lugrin, of Switzerland. His process has been pub- 

 lished in the bulletin of the United States Fish Com- 

 mission and also in the proceedings of this Society, 

 that is, so much of it as is known to any one but the 

 inventor. I think it was copied into our records two 

 or three years ago. 



There is a gentleman now in Europe who has been 

 investigating Mr. Lugrin' s methods. He cultivates 

 about one hundred thousand j^earling trout annually, 

 and he rears his trout on small insects, daphnia, 

 Cyclops, and fresh water shrimp. The gentleman re- 

 ferred to who is abroad investigating the matter is a 

 director of the Adirondack League Club, and is ex- 

 pected home within the next month, when he will 

 bring home with him all that he has been able to learn 

 about the matter. The inventor of this process, if it 

 may be called so, and he does call it a secret process, 

 declares the details of rearing the trout food has never 

 been given out to any one. Visitors have come, observed, 

 and gone awa\' ; but he has never had occasion to give 

 its details to any one. I am waiting with considerable 

 interest to see what the New York investigator will 

 report when he returns. He writes that the plant can 

 be enlarged. It is a mere question of adding to the 

 rearing troughs or basins. Lugrin's plant provides 

 for rearing only 100,000 trout a year, as that is all 

 there is demand for in Geneva, but he claims that it is 

 only a matter of increasing the number of food basins 

 to enlarge the plant to a million or more iish, as the 

 basins create their own food There is another for- 

 eign experimenter whose methods are similar in one 

 particular at least to those followed by Mr. Mather in 

 his experiment, and this is Carl von Scheidlier, an 

 Austrian fish breeder, but he professes to have several 

 methods. All of these secrets all grouped under what
