to those who wish to stock their ponds with the 

 individuals of other climes. In doing so, it is 

 necessary to consider whether the species delight 

 in running or smooth water, and whether they 

 affect a clayey, stony, sandy or muddy soil, or 

 one luxuriant with vegetation. In general, all 

 fresh water fishes delight in lakes that are tra- 

 versed by currents, and have a bottom of various 

 kinds, such as most large sheets of water afford. 

 Ponds or lakes, with high and rocky banks, are 

 not so fit for acclimating new species, as those 

 in which the banks are low and flat ; because 

 they are not so much exposed to the sun, and 

 consequently the temperature of the water is 

 much colder. In preparing a pond for localizing 

 fishes, its bottom and sides are to be provided with 

 wooden boxes or troughs, in which the spawn 

 may be deposited ; and the most favorable time 

 to transport them is, when this process is near at 

 hand. If it is wished to introduce many species, 

 it is as well to give to each kind their own pecu- 

 liar reservoir, adapted to their size and number. 

 After the spawn is deposited, the fishes should 

 be removed by a net from the pond, the boxes 

 are then to be taken up, and the spawn left to 

 be vivified by the heat of the sun. The reason 

 for removing the parent fish at this time is, 

 that their voracious appetite leads them fre- 

 quently to devour their own offspring, and thus 

 considerably to reduce their number. Another, 

 and a simpler mode of stocking a pond is, to 

 procure and put into it, from other waters, the
