up to tli(3 time of its spawning, in both flesh and flavor. 

 No food, however, has been at any time found in its 

 stomach after entering our rivers. There may be one 

 obstacle, however, to its introduction into European rivers ; 

 this is, that its spawn hatches out in the incredibly short 

 time of fifty -two hours. It was so proved on the Connecti- 

 cut river last summer, when forty millions of young shad 

 were produced by artificial impregnation and incubation, 

 and turned loose in that river. The young shad migrates to 

 sea the first summer. T. N.

DEAR SIR, Very many thanks for your most interest-

 liberty of publishing it in " The Field," and herewith I send 

 you a copy of the paper with a few remarks of my own

 of it with my remarks has turned up a prospect of some- 

 thing useful resulting. For the Earl of Breadalbane, who 

 is an old acquaintance of mine, wrote to me this morning 

 upon the subject, and said if I would start a piscicultural 

 society he would make a commencement, and put his name 

 down for 100 and a yearly subscription of 10 or 20 as 

 the case might require. Since the acclimatization society 

 broke up my fish cultural establishment, we have been at a 

 standstill. Indeed, we have been going back, and nothing 



practical has been done in pisciculture or even attempted.
