the end of the season. The water must be raised by the 

 cross-strip before mentioned as soon as the eggs hatch out. 

 It would be well to fix a small screen in each alternate cross- 

 strip, which can be done by cutting out a space of eight 

 inches by two, and nailing a fine screen over the orifice. 

 This will prevent the Trout from running up and down in 

 the troughs, and inconveniently crowding togetber. The 

 fry are removed from the troughs into the pond by the use 

 of a small net, such as described among the implements of 

 the fisli raiser. Take them upon this, a few at a time, and 

 put them in a pan of water ; they will swim ofi the net and 

 you may draw it from under them. In the pan they may 

 be carried, a thousand at a time, to the pond in which you 

 wish to place them. Put them into still water ; they will 

 settle down on the bottom and remain there for some 

 hours ; then they begin to explore their new^ quarters, and 

 in a few days will become thoroughly habituated to the 

 place. The pond should be covered over almost entirely 

 with boards ; this for two reasons : First, to avoid the 

 fungus growth which will form in summer in the ponds 

 wherever the sunlight comes. We mean the long, green 

 fibres of moss which rise from the bottom of the pond, and 

 which in this locality are called " frog spittle." On a bright 

 sunny day this becomes detached from the bottom, and 

 rising to the top of the water floats down with the current 

 and clogs the screens ; besides it fills up the pond so that 

 the food which is thrown in sinks down into it — the fish 

 cannot get at it, and decaying on the bottom it ibuls the 

 water ol the pond. Second, because the fisli require a 

 shelter in stormy or cloudy weather. In their natural state 

 we see young fish feeding on the shallows under the bright- 

 est sun ; but in cloudy weather not one is to be seen — they 

 have sought shelter under stones, weeds, &c. Still the 

 fish require sunlight, and enough should be given to keep 

 them in good condition. The board covers are also inci-
