the female Names-The rainbow trout
IL known also as California mountain
trout. speckled trout, golden trout, and
brook trout
Dstribution.-This species ranges from
California, near the Mexican boundary.
to Southern Alaska. A small specimen
was taken at Stka in 1880 by Captain
l.. A. Beardslee. United States navy. The
rainbow IS found chiefly In mountain
streams west Of the Sierra Nsvadas. IL
rarely descends into the lower stretches
OF the rivers. but occasionally does so
the rainbow has been rather extensively
introduced. but with such imperfect re-
suits In most cases that the Fish Com
mission has practically given up Its dis
tribution. The species reproduces natur-
ally in Cumberland county and In Mil
Creek In Pike county, and doubt
less In other streams.
This trout has been very widely dis
tributed artifcially, and In numerous
ri oil
pectations Favorite States for this spe-
cies are Wisconsin. Michigan. Missouri.
and North Carolina. In Missouri the
growth OF the species Is most remarkable.

inch per month up TO the age of one year.
Sze.-The average individuals OF this
species are less than one foot In length.
but specimens measuring nearly two feet
and Weighing eight pounds have been re-
corded. The Neosho station has individ-
uals nearly one foot long at the age OF
one year.
Habits and Reproduction.-The rainbow
feeds on worms, insect larvae and sal
mon eggs. In streams in which the Cali
fornia salmon and rainbow exist together.

structive 10 salmon eggs. Spawning takes
place In winter and early spring. varying
with temperature and locality. The bulk
OF the eggs are usually taken in January.
February, and March. and the average
yield from each female is about 800 eggs.
