milk can of the standard type. Of the larger fish we are shipping about 

 75 to the can. 



Mr. James Nevin, Madison, Wis.: We are shipping now from 100 

 to 125 ; they are about the same size as yours. 



Mr. Titcomb : We are shipping some of ours 125 to the can, but 

 the largest size runs 75 to the can. We would not be able to supply 

 our applicants with fish if we shipped them all when they attain the two 

 inch size. We make our allotments to applicants by cans instead of by 

 the number of fish. We give one or two cans to a mile of stream, 

 regardless of the time when the fish are distributed. We begin to 

 distribute when they are small fingerlings, and thus avoid congestion in 

 the hatcheries. The applicant can have the largest fingerlings if he 

 makes request for them, in which case his application is held over until 

 the fish run about 75 to a can. Another applicant may get 1,000 in a 

 can of these small fingerlings, or even more. By alloting by cans in- 

 stead of by number of fish I do not have apprehensions at the end of 

 the season about failing to fill all applications. We usually have several 

 carloads of these larger fish to sweeten up people with and make en- 

 cores to clubs, and so on. If you send them some of these fish that 

 run 75 to the can, they would rather have them than 5,000 fry. 



Mr. Lewis Radcliffe, Washington, D. C. : Mr. Titcomb is to be 

 congratulated on his efforts to get more specific information as to the 

 time when certain of these fishes spawn, and the temperature of the 

 water at that time, and also to get more definite data as to the produc- 

 tivity of these various ponds. The fishermen in some localities recognize 

 in a general way when to expect the fish ; they say, for example, that 

 when the dogwood is in blossom, shad may be expected. I believe that 

 in many cases they do not realize that the conditions which bring the 

 dogwood into blossom also bring the shad into their waters. 



Mr. W. C. Adams, Boston, Mass. : It seems to me that this is the 

 proper place, in the course of a discussion of trout culture, to describe 

 the plan which Massachusetts put into operation last winter. It consists 

 in planting eyed trout eggs that will hatch in anywhere from five to ten 

 days after they are planted in the spring holes picked out for them. 

 Our scheme has been to take a certain number of these eggs and the 

 ordinary wire that we use in the hatching troughs, turn the wire up at 

 the side so as to make a tray of it, about two feet long, the width being 

 that of the wire ordinarily used for the purpose. We anchor this tray 

 in a spring hole which is tributary to one of our trout brooks, in such 

 a way as to have it, say, a couple of inches off the bottom of the spring 

 hole or section of brook, in order that there will be plenty of ventilation 

 all around the eggs. Then, having anchored the tray, we put the eggs 

 on it, limited in number to avoid any possibility of overcrowding. This 

 •done, we thatch over the top of the tray with very heavy brush, and put 

 finer stuff on top of that to conceal it from predatory animals and birds. 

 Our observation has been that after these eggs hatch the young fish 

 drop into the silt in the bottom of the spring hole or brook and stay
