352 THE PROPAGATION OF TROUT. 
repay a journey of any lover of Izaak from any part of the country to see. 
But this is not all. He has another pond, right by the side of this, 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 should live in so small a space, but it is also accounted for and 
made plain, when one learns that the water in the ponds are 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 6,000 spawn each, and from that down 
to 200, according to size. Last year Mr. Green hatched as hfgh 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 perfect impreg- 
nation. I could see the young trout in almost every egg that had 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. 
It costs him but little to feed his trout. He tells me they get fully 
three-quarters of their living from the insects (as above) in the water 
running through the ponds. He thinks the trout in his ponds, and in 
the creek, devour fully 600 pounds of these various insects daily. 
These facts show how profitable the cultivation of trout can be made 
with proper water and care, and also the ease with which all the depo- 
pulated waters of the country can be restocked. 
The spawn can be transported from the eighth to the fifteenth day 
after impregnation, in glass bottles filled with water, by express to any 
part of the country with safety, and will nearly all hatch if distributed 
thinly over well-prepared gravel beds in the stream near the spring 
where the current is gentle, and the temperature remains from 40° to 
46° through the winter, and will nearly all take care of themselves 
after hatching through the spring and summer, and grow to from 3 
to 5 inches in length by fall. This is the easiest and cheapest way 
to stock all streams and ponds where the temperature and water will 
permit. But where they will not, then they must be stocked with 
trout. 
An outlay of 5 dols. to 500 dols. in spawn, and preparing the stream 
and gravel beds according to the amount anyone may feel disposed to 
invest^ will produce a corresponding show in the early spring of young 
trout. Some of these young trout will spawn in the fall, and all the 
fall following, and with proper care in a few years fully stock the stream 
or pond, and will pay the owner and angler for all the expense and
