up with feather at regular intervals.
1t looks rather odd to novice to see
the use made of feathers in handling
both eggs and fry as the young fish
are called. Dead eggs and fry turn
white and they must be removed at
once or disaster will result for the re-
naming ones. A fungus developes on
dead eggs which will destroy the live
ones unless removed and dead fry will
soon render the water unfit for the liv-
ing
The removal is made one at a time in
the case of eggs by using a small glass
tube with a rubber bulb on the end.
This takes them up by suction With
fry the living are removed by rubber
hose which acts as a syphon and later
the dead are washed out.
There have already been shipped out
and planted in various streams of the
state this spring, $50, 900 eastern brook
trout from the Hay Spur hatchery and
there are now on hand so, 900 more of
the same variety of the size called
fingerlings. These are already for ship
ping. Of the native or Silver creek
variety there are fry and eggs to the
number of $50, 900 now in the hatchery.
All of these will be in the fry stage in
few days. An even million of trout
planted in the streams of the state
from one little hatchery is not so bad
record after all.
1t was related in the Journal in the
early spring that Mr. Isaac had placed
an Indian trap across Silver creek near
the hatchery for the purpose of holding
the spawning trout where he might sein
them easily. After the snow had all
melted and there seemed no possible
danger of a rise in the stream to en-
danger the trap in which there were
swarms of fine fish ready for spawning,
Mr.. Isaac was obliged to go to Bellevue
on business, the time required being
only two hours. A hand was left to
watch the trap in the meantime. When
he returned he found that the creek had
suddenly risen and loosened the moss
which collected on the Stats of the trap
and backed the water up till the pres
sure had broken through and the fish
were on their way up stream.
Jumping into the cold water he saved
enough of the racks constituting the
trap to make a single line across the
stream and these he carried up stream
and threw them across in time to hold
the larger portion of the big fish that
had escaped from the trap. He then
to sein the creek for a long
distance below the rack and managed
to secure sufficient fish to yield about
300, 600 eggs.
The superintendent of the Hay Spur
hatchery has the faculty of making
Good. Coming to Idaho several years
ago with five years experience in the
U. S. fish service he engaged in the
state work in a subordinate capacity
and made a success of every undertake
ng with which he has been connected.

worry necessary to accomplish results.
