2. The most commo and profitable use
of crossing has been to improve onmou
breeds OF animals, or rather to transform
them into the improved breeds. This has
become SO common in all parts of the coun-
try that it is Unnecessary to dwell upon it !;
it is never amiss, however, TO remind farm
ers that improved animals always need i'm
proved care and feed. Five or six crosses
with careful selection will transform almost
any scrub animals into thoroughbreds, or
into animals that cannot be distinguished
from thoroughbre,is, and which for all prac-
tical purposes are equal to them. 1t would
then, require Tut q few years OF united en-
deavor to cause the scrub animals to disap-
pear from every part OF u country and an
imals as good rs our best thoroughbreds to
take their place, We're it not for the ~increas-
ed requirements of such animals and the ap-
parent impossibility OF SO suddenly modify
ing our agriculture as to provide the neces-
conditions for their existence.
