TROUT BREEDING. 93 



pools a short distance above the pond. From thence it 

 flows over a prepared bed of gravel to the pond. Perhaps 

 one man in a million might have thought that a fish-pond, 

 and above all, a place for speckled trout, could have been 

 made in the spot where this is located. The water is four- 

 teen feet deep in the main pond, and this depth has been 

 secured by excavation the original depression being very 

 slight, although the spot was swampy and of little value. 

 As a means of saving every drop of the small supply of 

 water, two parallel walls have been built around the pond, 

 sunk into the blue clay, and the space between them 

 grouted, so that not a drop is wasted except by solar evapo- 

 ration. At the bottom, large stones are placed in positions 

 to afford hiding-places for the trout whenever they choose 

 to retire from the hot sun. In this respect, Mr. Ainsworth 

 has studied the habits of his finny stock, and as far as he 

 could, compensated them for removing them from their 

 native streams in Victor, Springwater, and other places, 

 where they were captured. The walls around the pond 

 are carried to the height it is intended the water shall 

 reach, and then a sufficient quantity of earth placed over 

 them to sustain shade trees, a large number of which are 

 in a thrifty condition. The water comes into and passes 

 from the pond through fine sieves, through which nothing 

 but the water can pass. 



" Inside of the parallel walls there is a slope wall, and 

 from the top the ground recedes in all directions, so that 

 no surface water is washed into the pond. In places where 

 it is likely to stand too long it is carried off by tiling.
