they feed very little, owing to the scarcity of food at this season. 
They then hide under stones and banks, and in deep holes out of 
the reach of their enemies. 
When the weather becomes warm, about the beginning of April, 
they leave their winter quarters and roam about in search of food. 
Towards the end of April a great change comes over them—a change 
almost as great as that from a parr to a 

smolt. They now assume a silvery coat, 
and it is difficult to tell them from the 
smolt of the sea-trout. During the summer 
they feed on worms, flies, larva, beetles, 
shell-fish, and many different kinds of flies 
that are blown on to the loch or stream 
from the land. By March of the following 
year, if the feeding has been fairly good, 
they will be from 8 to g inches long, and 
will weigh about 4 0z. I have seen some,

three-years-old trout is usually about three-quarters of a pound, 
while in streams they are usually much smaller. 
In quick-running streams containing little food, many, when 
three years old, will not weigh more than 3 oz., showing clearly 
that their size at a certain age depends chiefly on the feeding. 
At four years of age they should weigh 1 to 14 lbs. ; at five years,
