be filled with trout. The spawn from half a dozen pair of 

 trout per annum would furnish young fry enough to make 

 good fishing in any brook in the State. Several people in 

 the State are making experiments in artificial trout raising 

 with a good degree of success. But they have generally 

 commenced with little or no instructions or experience upon 

 the subject, and have often met with reverses that a better 

 knowledge of the business would have prevented. 



AETIFICIAL TKOUT RAISING. 



To aid such as may desire information upon this subject, 

 we will here introduce very clear and valuable instructions 

 from the pen of Hon. S. H. Ainsworthof West Bloomfield, 

 New York, who has been very successful in artificial trout 

 raising. 



BEST METHOD OF CONSTEUCTING PONDS. 



" To grow trout successfully, there must be three ponds, one 

 above the other, in the same stream if possible, as it saves 

 much time in transferring the small fry from one pond to 

 the other, as they increase in size. The object of these 

 ponds is to keep the young trout out of the reach of the 

 larger ones untU they are of sufficient size to take care of 

 themselves, which requires two years at least. Pound trout 

 would soon exterminate a pondful of one year olds, if not 

 well fed, and undoubtedly take more or less of them if well 

 fed, so that they would soon run out if left together. The 

 first or upper pond is to grow the small fry in the first 

 year ; the second one for the second year's growth. In the 

 spring of the second year they will geneally be large enough 

 to care for themselves — say from seven to nine inches long, 

 and from four to five ounces in weight, if well fed. They 

 may now be turned into the lower or large pond. The first 

 pond may contain from one to eighty square rods, and be 

 from one to three feet deep, according to amount of water, 

 and number of trout one wishes to grow. The second pond 

 from 300 to 400 square rods, and from two to eight feet deep.
