128 Salmon at the Antipodes. 



oxygen by being inhaled in passing through 

 the gills, the fish must become suffocated, 

 as certainly as would a human being, if shut 

 up in a close box without fresh air. Certain 

 fish do not suffer in this way; but active 

 fish, such as salmon and trout, which are ac- 

 customed to highly aerated water in the rapid 

 rivers or the seas which they frequent, perish 

 very quickly if confined in a small vessel of 

 water without a current. The remedy is to 

 give a supply of air at intervals, and the 

 simplest and most effective method of attain- 

 ing this object is by using a strong pair of 

 bellows, and an india-rubber tube about two 

 feet in length, to force the air to the bottom 

 of the fish-can. 



The tube should be corked at the end, and 

 pierced with a number of minute holes with a 

 fine wire made red-hot, so as to bring the air 

 into contact with as large a surface of water 

 as possible. When fish turn on their sides, 

 and are perishing for want of ah, a few strokes 

 of the bellows act upon them like magic, and 

 they immediately recover. In practice, I used 

 the bellows every 15 minutes, although less 

 frequently would probably have done equally
