Dr. Sweeny said that the " dogfish " referred to by Prof. 

 Jordan are considered a superior fish by the Hebrews of Min- 

 nesota, who call them "green bass." They are also called 

 " lawyers," because they clean up everything. 



Dr. J. C. Parker had noted what Prof. Jordan said about 

 the bullheads in East Coy creek. He had put his hands on 

 them. They were transported from Silver Lake and placed in a 

 horse trough at first and then escaped into the creek. There 

 were no bullheads there during his boyhood. 



Mr. Mather announced that he had received a private 

 letter from Mr. W. Oldham Chambers, Secretary of the National 

 Fish-culture Association of England, dated April 22, 1888, 

 which contained some matters of public interest, and he would 

 read such portions of it as related to the rearing of fishes. Mr. 

 Chambers says : "I am looking forward to a visit to America, 

 some time, for the express purpose of studying the vast 

 advances you are making in our glorious science. I can con- 

 ceive no greater treat than to exchange thoughts with my trans- 

 atlantic friends. I think there is this difference, if I am not 

 mistaken, in our methods ; you devote all your energies to 

 hatch out the greatest quantity of fry and then turn them out in 

 the rivers and lakes, whereas we try to invent means of feeding 

 and rearing them after the sac is absorbed, and then turn them 

 out when they are capable of caring for themselves. I have 

 never met with anything that approaches my "thorough " sys- 

 tem of feeding. You can make a vase to bring up 100, or one 

 large enough for 100,000 with the same ease, and on the same 

 principle. The fish are bound to be on the move and are 

 equally bound to feed, because the food is always held in 

 suspension and has no chance to get to the bottom. I inclose 

 a sketch, to scale similar to one in my hatchery that now has 

 15,000 rainbow trout in it. Oblige me by making one, which 

 you can do at a small cost, and give me an opinion of the 

 result. There is no patent on it, so do what you like with it. 

 Be careful to follow the lines laid down in the inclosed diagram, 

 especially in the case of the holes in the pipe which must be at 

 the proper angle, for there rests the secret."
