When a pure-bred stallion is mated
with n native or mongrel-bred mare

When a grade stallion is mated with

there has been no grading up In the

their retention for breeding purposes
Is inadvisablc when legitimately re-

in their place.
The pure breeds OF horses have
been bred In one line for so many
years without an admixture of alien
blood that each stallion representing
pure breed is possessed of the power
to transmit at least the designating
bred characteristics OF his kind. Some
pure.bred stations have more power
than others in this way and the degree
Of power tprepotencyD may be said to
depend largely upon the degree OF pre-
potency possessed by each individual
ancestor and the length of time those
ancestors Of the individual horse have
been bred pure In a direct line. Some
times the pure-bred stallion may not
be so individually excellent as We
could wish. but almost inevitably, II he

will transmit successfully the charac-
teristics of his breed and in many in
stances some of the superior qualities
