A grade" horse, strictly speaking,
Is one that was sired by a pure-bred
stallion. Always the sire must be
pure-bred, If the progeny is to be en-
titled to the name of grade" Where
pure-bred mare Is bred to a grade
stallion her progeny is not grade"
Such breeding is de-grading-a step
backward and downward-and, the
progeny which has not been graded up,
but degraded down, is of mongrel
breeding
When pure-bred STALLION is mated
with native or mongrel-bred mare
the product of this first mating is a
"one-topcross" grade. the offspring
being one-half pure blood and one-half
female and in turn is bred to a pure
bred stallion, of the breed used for
the original topcross, her progeny will
be "two-top-cross" grade. or three
quarters pure-bred. When five top
crosses of the same kind of blood have
been put on, the last resultant Off
spring is practically pure bred, and il
the work of further top-crossing is per-
sistently carried on, without single

When grade stallion is mated with

possibly be made SO long as a grade

Of the pure blood of the one predomi-

stamp with fair degre of fidelity
the characters of that breed upon the
progeny of all classes of mates. Such
horses, however are not eligible to
record in a majority of the govern :
ment recognized stud books, hence
their retention for breeding purposes
is inadvisable 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
