100 AMERICAN FISH CULTURE. 



30 by 50 feet, which contains 20,000 beautiful trout, 

 mostly one and two years old, from six to nine inches long, 

 all taken by his own skill, as above. He has still another 

 pond, filled with last spring's fry, from three to five inches 

 long. 



" It seems incredible at first thought that such a vast 

 number of large trout could live in so small a space, but 

 it is all accounted for and made plain, when one learns 

 that the water in the ponds is changed every minute 

 through the day by the large current constantly pouring in 

 upon them of this cold, pure spring water. 



" Some of the trout produced 6000 spawn each, and 

 from that down to 200, according to size. Last year Mr. 

 Green hatched as high as 98 per cent, in some instances — 

 in others, about 80 per cent. This year he expects to 

 hatch nearly all, as he has become master of the business, 

 and knows the right time to take the spawn to insure per- 

 fect impregnation. I could see the young trout in almost 

 every egg that bad been taken fifteen days, with the naked 

 eye, so that I know his success is perfect so far. With 

 this continued success he will very soon be able to stock 

 all the private streams and ponds in the country with spawn 

 and young trout, as well as to furnish tons yearly for the 

 table of this, the most delicious and costly of all the finny 

 tribe.'' 



The culture of trout I have conceived to be of so much 

 importance, that I have gone much into detail in every 

 thing bearing upon the subject. It may perhaps be tire- 

 some to a portion of my readers, but my excuse is, that it
