mon and cross-bred fowls are offered for sale. their 
parentage being stated in advertisements. It is not safe 
to breed cross-bred fuwls together, as.the resulting 
progeny is very likely to show the defects of remote 
parentage, as well as to fail in that uniformity in size 
and prolificacy that the breeder has reason to anticipate 
in breeding stock of known bleod. Many times a verv 
common flock is bred up to show geod quality by intro- 
ducing pure-bred males, and continuing to breed to pure- 
bred males, always using the same variety that was used 
in the beginning. Where this is done it is quite possible 
within five or six years to breed a flock up to the point 
where it is practically pure-bred. 
DAY-OLD CHICKS, HOW TO CRATE.—The busi- 
ness of shipping day-old chicks to buyers is constantly 
growing greater. Some breeders ship them in flat trays 
about the size of berry crates, one tray above another, 
held apart by tacking strips on each corner. Others sep- 
arate the chicks in pasteboard holders similar to those 
used in egg cases. In any event the tops of the trays 
should be covered with burlap, which gives plenty of 
air and keeps the chicks warm. Chicks are frequently 
shipped more than 1,000 miles without injury, but further 
than this they are liable to become stunted and show the 
effect later. (See cut of crate on page 247.) 
DEAD FOWLS A MENACE.—Dead fowls should be 
burned or buried deeply at a considerable distance from 
the poultry range to prevent others of the flock from he- 
coming diseased. It is best to burn such dead fowls, if 
it is convenient, as the fire absolutely destroys disease 
germs, while burying them does not alwavs completely 
destroy them.
