106 THE NEW ART OF BKEEDING FISH. 



circumstance of a happy distribution of the different 

 waters which run from one side to the other. 



When the spawn have arrived at the growth of 

 young fish suitable for stocking streams, the Rhone 

 and Ehine canal, which runs between the two long 

 lines of ponds where these fish are kept in reserve, 

 will itself be the natural means to conduct them into 

 aU the waters of France by means of their intercom- 

 munications. To attain to this object, a jointed raft 

 should be made of pieces of wood transversely placed, 

 and connected by iron rings, and in the interstices of 

 this raft would be fastened casks sufficient to hold 

 the entire supply of fish. These casks should be pro- 

 vided with gratings so as to be permeable, and con- 

 tain water-plants, so that the young fish are not in- 

 juriously crowded. 



The convoy so disposed should stop successively 

 before each pond, and right and left, the workmen 

 attached to the ordinary service of the canal, will 

 empty into it the fish drawn from these drains ; then 

 the cargo completed, the raft will be set in motion, 

 and the casks with their bottoms knocked out from 

 time to time, will sow the fish, as a plow would sow 

 seed if capable of doing thus as fast as it made fur- 

 rows. 



When the convoy will pass the point of junction 

 of another water-course, one of its sections, as they 

 are fastened by rings, could be detached as a wagon 

 is from a train, and given to the engineers of the 

 country traversed by this stream of water ; these en-
