and all in a healthy condition, where they grow rapidly and 

 get fat on a small quantity of curds fed to them once a day : 

 these Trout are even preferred to those caught fresh from the 

 Saucon, which flows close by. The trough in question con- 

 tains seventy-two cubic feet of water, and when it has seven 

 hundred and twenty Trout in it, there are just ten fish to a 

 cubic foot. This useful aquarium was established many 

 years ago by Mr. Desh's father ; Trout seldom die in it. The 

 spring which supplies it rises in the garden, a few yards 

 above, and would flow through a hole an inch and a half 

 square. The fish are bred naturally by a farmer in the neigh- 

 borhood, and brought in large tubs. There have been in- 

 stances of their breeding in the trough.
