attendant with large shipments of fish, particularly over routes in- 

 volving a number of transfers, is recognized, but in any event, the 

 jacketed can will still have a distinct advantage over the cans in com- 

 mon use. 



4. The underlying principle involved in the plan is the cooling 

 effect of evaporation, and since heat greatly stimulates evaporation, 

 it would seem that the principle might be successfully taken advantage 

 of, within certain reasonable limits, in almost direct ratio to the need. 

 It is not claimed that the device is perfect, nor have its full possibili- 

 ties been exhaustively demonstrated, but the results obtained so far 

 in maintaining a lower temperature of water in shipments of live fish 

 without an attendant, warrant its general adoption. 



Discussion. 

 Mb. G. C. Leach, Washington, D. G. : On September 2d a shipment of 

 50 bass was sent from Logansport, Ind., to Washington. They were in 

 what is termed a oO-pound lard can, jacketed according to the description 

 given in the paper. They arrived in Washington, after having been on the 

 road 24 hours, with a loss of but 10 fish. The temperature on arrival 

 at Washington was approximately 62^ F., about the same as when the ship- 

 ment started. The loss of the 10 fish was probably due to the fact that 

 the can remained in the station about aa hour and 15 minutes, the water 

 being in an inactive state. 



Mr. Fearnow does not claim that his device is going to solve all the 

 problems in regard to the transportation of fish, but he believes that a 

 messenger so equipped may go to some central point and distribute fish 

 east, west, north and south by express, saving possibly several trips. He 

 does not claim that the jacket on the can is going to be effective when the 

 outside temperature is below 50° or 60° F. It will be more valuable during 

 the very warm weather in the summer, and it is going to be very successful 

 in making shipments of trout or bass for a period of four or five hours, 

 but it is not expected to cover a period of 24 hours, though under certain 

 conditions we can ship warm water species that long with considerable 

 success. The can offers possibilities for shipment of goldfish and top 

 minnows. 



Mr. J. W. TiTCOMB, Albany, N. Y. : With one exception, the experiments 

 were with warm water, above 60° F. Would it help to keep the tempera- 

 ture down in the case of trout, starting with 45° ? 



Mb. Leach ; The canvas jacket around the container absorbs the water 

 that slops out, thus keeping it saturated. The evaiwration will cause the 

 temperature to rise slowly, and if the start is with water at 48° F., four or 

 five hours at least will elapse before it gets up to 53°, or before it would be 

 injurious to the trout. It is not claimed that it will carry trout as far 

 as it will bass. We realize that the express companies are slow in handling 

 the fish, therefore, to expedite the matter we expect the messenger, when 

 he arrives at the central shipping point, to put the cans in the express car 

 himself. I do not believe more than 5 per cent of the applicants fail to
