MILXER ON THE ARTIFICIAL CULTURE OF THE SHAD. 451 



sylvania, Ohio, Michigan, Wiscousin, and Minnesota have appointed 

 commissioners and made appropriations for propagation, while Indiana, 

 and Illinois have passed protective laws as to the obstrnctiou of the 

 passage of fish in the rivers. 



The State of Michigan has erected a large hatching-house, and 

 v,i\\ propagate the white-fish of the lakes on a large scale. The judi- 

 cious management of the New York State commissioners has made 

 their work very efficient, and people from all quarters of the State have 

 visited the hatching-house and carried back thousands of young fish, 

 without charge, to stock the waters in the vicinity of their homes, some 

 half-dozen species of food-fishes being afforded in quantities to all who 

 applied. 



A very general and strong interest was exhibited on the southern 

 rivers at the attempt to hatch shad, which made very little success, be- 

 cause of the great reduction of numbers in these waters and the conse- 

 quent lack of spawuers. The promises to endeavor to supply their 

 rivers with a new seed -stock from more northern rivers was met with 

 earnest interest and satisfaction.
