spawn of a single fish, and found it to be seven or eight 

 feet long. It is really a tube extruded in folds arranged 

 like the bellows of an accordeon, and when closed is only a 

 few inches long. We found one of them with half of the 

 spawn extruded, and that side was Hat, while the other 

 was full and round. By squeezing out the othei' half, we 

 were able to see how the spawn was deposited." 



A paper was then read by Mr. William T. Seal on the 

 transportation of living fishes. In response to the request 

 of the Chair, Dr. Gary said : " Some years ago I remember 

 reading in the F'is?! Commission Bulletin tliat a number 

 of carp, I think about fifty, were shipped to various parts 

 of the country by express in a small tin X)ail holding about 

 six quarts of water. I myself carried in a small fish bucket, 

 about the same size, fish from Washington to New York, 

 and from New York back to Washington and then to At- 

 lanta, Ga., without losing a single fish. The question I 

 want to ask is, if a given number of fish can be better car- 

 ried in a small quantity of water than in a large quantity V 



Mr, Seal said: "It is not the quantity of water at all, 

 but the fact that where the water is shallow there is greater 

 agitation and consequently better aeration. The shallow 

 bucket referred to by Dr. Gary is the one that has been 

 adopted by the United States Fish Gommission. Where 

 there is much dej^th of water the surface is much agitated, 

 and the bottom may be wholly unaerated and foul." 



Mr. Mather said : " The case that Dr. Gary cites was with 

 carp, but that will not work with the trout. In the trans- 

 portation of trout and salmon we have for the past three 

 years at the hatchery which I sux)erintend abandoned the 

 use of the siphon and strainer tube, and have used a gar- 

 den syringe about twelve or fifteen inches long, which we 

 like much better than anything else." 



Mr. Clark said: "The line that I was working on was 

 not in transporting fish, but in seeing what I could do in a 

 hatchery in keex)ing them there. In my experience I found
