 into the ponds, in fearch of water and nouriftiment. 



31. From thefe obfervations, it appears, that 

 trouts cannot multiply in ponds. On the other 

 hand, we know, that it would be impoflible to pro- 

 cure every year a young brood out of dreams. Be- 

 fides, we don't "find trouts in every dream, although 

 there ftiould be ponds near, fit for feeding them. 

 Therefore, this method of procuring trouts, by 

 means of the eggs and milt, mud be ufeful in many 

 places, beiides the pleafure and amufement of 

 breeding them. 



32. Salmon in their fpawning feafon pafs, as 

 trouts do, from deep rivers into pebbled dreams, 

 and having fpawned there, return to the rivers, 

 where the fry come to feek them as foon as they 

 can. Such is the indinft which nature has given 

 them ; whence we may conclude, that young fal- 

 mon do not remain in dreams, and that it is diffi-

 as pike, trout, &c. when they are kept in ponds, 

 feed principally upon water-rats, frogs, &c. and as 

 falmon ufe the fame food, it would be well done to 

 throw a great quantity of them into the ponds,
