8 DOMESTICATED TROUT. 



accidentally moved a small gate which regulated the 

 supply of twelve thousand fine, healthy trout fry 

 belonging to the writer, and at half past ten the 

 same evening every fish was dead on its back. The 

 gate was not moved over an inch ; the consequence 

 was the death of twelve thousand beautiful young 

 trout. 



For instance, again, a freshet that you have not

A score of instances within the writer's knowledge 

 might be mentioned, where actual losses of great mag- 

 nitude have occurred in each one of these ways, when 

 the only cause was insecurity. Thus it is seen that 

 losses, when they do occur, are frequently so disastrous 

 that no degree of security in guarding against them 

 seems excessive. As in business, so in trout raising,

 constantly present. Plant your corn in the field, or 

 turn your sheep out to pasture, and they are tolerably

 are few , but hatch your trout in the water, and not 

 a moment, by day or by night, are they free from
