water over my spawn, and if any sediment gets on them and 
is allowed to remain there long, it will surely kill them. Re- 
move all sediment with the bearded end of a quill by agita- 
ting the water, without touching the spawn. 
“Large ponds with but little water get too warm in sum- 
mer and too cold in winter for trout to do well. It is detri- 
mental to have any other fish with trout. Any kind of fish 
or fish-spawn is good for feed. The young should be fed 
twice per day, very slowly; if fed fast, the feed sinks and be- 
fouls the trough, and the trout will sicken and die. If fed 
regularly, and the trough kept clean, with a good change of 
water, and not kept too thick, they will live and do well. If 
neglected, they will surely die. 
“What is Death to Spawn.—The sun, sediment, rats, mice, 
snails, crawfish, and many water insects. 
“My troughs are 25 feet long and 15 inches wide. The 
water that feeds each trough would go through a halfinch 
hole with a three-inch head. Use fine gravel that has no iron 
rust init. My troughs are three inches higher at the head. 
The average temperature of the water is 45°, and the fish 
hatch in 70 days. Every degree colder or warmer will make 
about six days difference in hatching. Trout hatch the soon- 
est in warm water. The sack on their bellies sustains them 
for 40 or 45 days after hatching; then they need food. 
“When the fish are hatched, raise the water in the troughs 
about four or five inches by putting on a piece of board of 
that width on every cross-piece, thus keeping the fish sepa- 
rate—about an equal number in each square. If you have 
small streams of shallow water near the head of your pond, 
put a few in a place in the stream and pond, and they will 
take care of themselves better than you can. The object of 
distributing them is that they will get more food. All old 
streams and ponds have plenty of food for small trout and 
large, which you will find by examining the moss, sticks, and 
stones in your ponds and streams, as they are full of water- 
insects.
