6 HOME FISHING AND HOME WATERS. 



we may be sure he will not relax in the quest for 

 new results, so long as his wonderful energy and 

 vitality last. What the late Professor Spencer F. 

 Baird was to explorations in the waters of the 

 ocean, Mr. Green has been and is, to the activity 

 of research in the lakes and streams of our country. 

 The practical work of Pisciculture began in New York 

 in 1868, in the establishment of the State Hatch- 

 ery at Caledonia, in Livingston County. From this 

 hatchery from one to two millions of speckled trout 

 have been annually distributed, and streams and pre- 

 serves in all parts of the country have been stocked 

 or replenished. There are many similar establish- 

 ments in various States, but those in New York and 

 New Jersey may justly claim pre-eminence. In 

 thirty-seven States and Territories Fish Commissions 

 have been organized, and a noble work has been 

 accomplished. The introduction of the German 

 carp, a fish in supply all the year round, except 

 during the period of spawning, is one of the most 

 valuable achievements of the period. The almost 

 incredible fecundity of fish is made to serve the 

 purpose of steady increase, and the young and ex- 

 posed fish are protected from their natural enemies. A 

 codfish produces from one million to nine million 

 e gg s ; a salmon one thousand to the pound of 

 weight ; a shad fifty thousand in all ; a herring 

 twenty-five thousand ; a trout from two hundred 

 to three thousand according to age and size. Under 

 ordinary circumstances, millions of these eggs cast 

 into unprotected waters, are unimpregnated, or are 

 lost or destroyed. It is the task of all fish cultur- 

 ists to prevent this waste in great part, and to pre-
