II4 BRITISH SPORTING FISHES. 
the stream-margin with brambles and cresses, 
the better. The first bring food, the second 
afford protection. About four inches of running 
water is probably the ideal depth for fry. They 
may be “sown” in the stream as local conditions 
suggest. The sowing ought always to be done 
proceeding down-stream; “hides” and “rests” for 
the fish should be inserted. These are com- 
posed of two bits of brick placed about four 
inches apart, and covered in with a piece of 
slate. Into these the fry dart, and are safe 
from their larger enemies, of which they have 
many. One great advantage of turning fry 
into brooks is that in time of “freshets” and 
floods they are enabled to get into the quiet 
eddies, and are not swept down by the rushing 
waters. 
When the fish of which we have been speak- 
ing descend from the streams, they are from 
two to four inches in length, and are known as. 
“vearlings.’ These are turned down in the 
spring months, and from their age and size, a 
greater percentage survive than in the case of fry. 
As the fish increase in size, they have fewer, but 
larger enemies. Otters, probably, do little harm 
to trout at this stage of their growth, preferring, 
as they pass up the shallow streams in summer, 
other game. Fry are often kept to grow into
