varies in volume, and so make ponds. There should be 

 enough level land by the side of such a stream to make 

 ponds supplied by the stream ; and it is best to 

 have a stream much greater in volume than is necessary 

 for the ponds, so that there ■will always be a good supply 

 of water, and there will be no trouble with the surplus 

 water after a freshet. A good knowledge of the whole 

 system of Trout Oultuie is essential in choosing the very 

 best location. It is desirable to have your ponds near 

 your house, or have a man in charge living at the ponds. 

 Of course your Trout may never be molested, but "an 

 ounce of prevention is worth a pound of cure." 



Laying Opt Ponds. — The diagram represents a series 

 of ponds, in all of which the same water is used. This 

 plan is generally considered the best, for several reasons. 

 It economizes the water and space, and is most conven- 

 ient for changing the fish from one pond to another. It 

 is not necessary that the ponds should be in a straight 

 line. Where the location demands it they may be turn- 

 ed so as to lie in a direction nearly or quite parallel with 

 one another. This is easily done by bending the race- 

 ways, and lengthening them if necessary, only a curved 

 raceway is sometimes not so convenient as if it were 

 straight. The sides of the ponds may be walled up with 

 stones, laid without mortar, unless the soil is very sandy. 

 "Wood may be bettei for the sides and bottoms, but we 

 are inclined to think is not worth its expense. If the 

 sides of the ponds are laid up with mortar, let it dry 

 thoroughly before letting the water in ; then let the wa- 

 ter run through it two or three weeks, or long enough 

 to purify the pond before putting any fish in it. It is 

 as well to test it by putting in only a few fish at first ; if 

 the pond is not thoroughly purified the fish in it will 

 turn blind. Ponds should not be built where much sur-
