 on a horse accubtomed to the sport, and graspins a spear 

 made tor the purpose, advance" towards the fish, and as 

 soon as the latter has dis"overecl its pursuer and is making 

 oft, a complete chase takes place between the horstnian 

 and the salmon. As soon as the. man finds himself nearly 

 up with his came, the spear is thrown with such force and 

 dexterity as seldom to nuss, and the salmon, entangled 

 with the weight of the spear, soon becomes exhausted. So 

 very powerful is the salmon in water, that were the man to 

 strike it while he grasped the spear in his hand, he would 

 instantly and inevitably be dragged from the horse.

On the Breeding of Trout. 



In the 23d Number of this Magazine, of the year 1763, 

 was given a short account of the breeding of trouts *: as we 

 have since received a more complete natural history from the 

 inventor himself, we hope it will not be disagreeable to 

 our readers to have a repetition on the same subject, as the 

 discovery really deserves some attention. The fisTiery of 

 this nimble and cautious animal is carried on in a destruc- 

 tive manner, and conimonlv at the spawning-time, when 

 root and branch are destroyed together. But now we enjoy 

 the pleasure of eating trouts, and have them replaced many 

 hundred fold, and have the spawn secured from the danger 

 it is exposed to in the open ponds. If the system of the 

 inventor should displease, it must be considered that he 

 does not mean to oflfer a new theory of generation, but 

 a iTjClhod of producing a greater number of fish for the 

 table; which last may be obtained without knowing the 

 nature of the first. Something similar to this is to be seen 

 in C. F. Lund's Treatise on the Generation of Fishes in 

 in-land Seas or Lakes. See the Memoirs of the Swedish 

 Academy of the year 1761, vol. xxiii. page 181." — We
