THE NEW ART OF BREEDING FISH. 79

 necessity of furnishing them any thing else than an 

 imperceptibly small stream of water, it is evident 

 that through our rivers and canals, boats suitably

 France, so that there is not a single point at which 

 they may not be distributed. 



TRANSPORTATION OF OLDER FISH. 



When they have attained a sufficient size to be 

 suitable to stock streams, the young fish are much 

 more difficult of transportation to a distance. Nev-

 they can be thus carried great distances and distri-

 and Detzem last year dispatched one of these convoys
