the atmospheric heat and reduces the water temperature sufficiently 

 to permit the carrying of warm-water fishes, even in low altitudes, 

 during the warmest weather. 



9. The pail is provided with a compartment for carrying ice 

 in the event that trout are handled during the warm summei 

 months. 



10. The lid of the minnow bucket is so shaped that it does 

 not permit the dripping of ice water on the fish, but feeds the water 

 from the melting ice into the fish compartment indirectly, making 

 the change of temperature very gradual. 



11. It automatically siphons pollution from the bottom of the 

 container when new water is added, maintaining a fixed water level. 



12. The tray of the minnow bucket type is made with a float 

 and may be used as a live car. 



13. The parts are made so that they will nest, requiring a 

 minimum amount of space in shipment from the hatchery or on 

 return trips. 



14. Air vents are provided in the sides of the outside container 

 and packages placed on the top of the pail do not exclude the air 

 from the fish, 



15. It is easier to handle, as one man can carry two pails 

 whereas two men are required to handle one 10-gallon can. 



16. It is useful in the transportation of fish eggs. 



17. The tray fits the standard hatchery trough and fish may 

 be counted at an opportune time well in advance of shipment and 

 held until required. 



18. It affords a safe and practical means of transporting fish 

 to the headwaters of streams which have heretofore been neglected 

 on account of their inaccessibility. 



There are many factors that must be taken into consideration 

 in carrying live fish. It is not the intention tJiat the device be used 

 with tray when carrying fry. Neither should it be understood 

 that the utilization of the swimming efforts of fishes can be advan- 

 tageously applied to all sizes of fish. The method provides for 

 holding fish in sanitary condition near the surface of the water, 

 jetting the water into the compartment when the receptacle is in 

 motion and utilizing the swimming efforts in emergencies only. 



It may be stated that a large saving in last year's distribution 

 allotment was effected by the use of the device described in this
