especially trout and bass. 



Mr. Titcomb : Where the can sets out on a warm day for several hours, 

 say at a junction point, how do you depend on keeping it iced? 



Mr. Fearnow : We depend on keeping warm-water fish cool by the 

 absorption of atmospheric heat through evaporation. The jacket has a flap 

 that draws the moisture from the can. Besides, if the jacket were thor- 

 oughly saturated and the can taken off the train at a junction point, it would 

 retain that moisture for a reasonable length of time. A shipment of trout 

 could be made for a reasonable distance, for 8 or possibly 10 hours, in hot 

 weather, by moistening the jacket and drawing the flap over as a protection 

 to the ice. The melting ice also assists in keeping the jacket moist. A ship- 

 ment of trout arrived at Central Station from White Sulphur Springs, West 

 Virginia, a few days before I left Washington. There were about 25 3J/^- 

 inch fish in the can and they arrived in excellent condition. So far we have 

 not had what could be considered a failure, a real loss of fish, in using 

 this device. 



Mr. F. E. Hare, Manchester, Iowa: How about the young fry? 



Mr. Fearnow : The idea is to carry the fry and up to fingerlings No. S* 

 size in the can without the compartment. In that case the problem of 

 aeration is insignificant. The upper tray serves as an ice container. It also 

 provides aeration because any water that happens to slop up through these 

 perforations will trickle back. In carrying fry the water should be up to 

 the siphon port; that is the normal water level. As to 4-inch fingerling 

 brook trout, in hot weather I would not attempt to carry over 75, 

 as in a 10-gallon can. Two of the Bureau's car captains who have tried the 

 pails have asked for full equipment of their cars. 



Mr. Titcomb: You quoted the Bureau of Fisheries Service Bulletin as 

 commending this method of transportation. In the closing part, it states 

 that if the test of the 65 cans you made continues to prove satisfactory, 

 all of the cars will be equipped. Have you reached the point where you 

 would say that the test was so satisfactory that the cars were to be equipped? 



Mr. Fearnow: We could have probably a thousand of these cans in 

 service now had I not wanted it subjected to every possible test. 



Mr. Titcomb: This other pail is really a minnow pail, is it not? 



Mr. Fearnow: It is valuable for carrying fingerling fish and adults, 

 but it does not seem to meet our special requirements quite so well as this 

 one. I make every claim for the minnow bucket feature that was made for 

 the other, with the exception that it cannot be used without the intermediate 

 compartment. It is not used on the cars. It would be valuable for collect- 

 ing fish at stations, or for use on messenger shipments. 



Mr. Titcomb: What entirely novel feature is there in the combination 



tray or lid? 



Mr. Fearnow: It is the process of aeration— jetting the water into 

 the compartment. It is really a combination of two trays provided with a 



float. 



Mr. Charles O. Hayford, Hackettstown, N. J.: This device is very 

 interesting to me, for in our State we handle practically all our distribution
