 It is therefore well in large establishments to have 

 a special can for keeping the fishes over night. 



If several cans are used at once but one air- 

 pump is necessary, as the india-rubber tube can 

 be removed from one can and slipped on another. 

 The pump should be made in the best manner and 

 with but one valve, as every additional valve will 

 double the chance of getting out of order a se- 

 rious matter when the lives of hundreds of fishes 

 are involved. Our first attempt at transporting 

 large fish in this tank was in December, 1869. We 

 desired to exhibit at the Show of the New York 

 Poultry Society a series of our finest fishes. Sev- 

 enty-one were selected, and though sixteen hours 

 elapsed before they could be placed in the Society's 

 tanks, but one fish died upon the passage, and 

 this was previously diseased. But one change of 

 water was made, and this was necessitated by the 

 upsetting of the can and the spilling of the fishes 

 in the bottom of the express wagon. Among the 

 fishes were ten averaging a pound and a half each. 

 "VVe were honored by the Society with a bronze 

 medal for this invention.* 



* We also received the great gold medal of the Society, value 

 eighty dollars, for our display illustrative of the science of fish 

 culture.
