POULTRY AND LINE BREEDING.
It's Value and Practice.

Line preceding IL Ine breeding OF iHui'
viduals selected from, or restricted to, 2
single line OF descent In the words OF
one authority: 1T is the process OF
breeding within one family or within a
limited number of families all OF which
have common ancestry and represent
similar types" Now, at first glance
the following may sound forbiddingly
complicated but when once the circles
are carefully drawn, shaded and num-
bered as directed, and it is remembered
that solid black line represents the
male and a dotted line the female, this
| line breeding chart becomes very sim
pie matter to follow. Besides, this ar
ticle is especially written by request for
! those whose earnest endeavor it is to
| breed only from tried and dependable
stock, and who are never satisfied to
| limit themselves to what is only second
best" in any form.
Those who intend to practice line
breeding should be careful to make their
matings from both pedigree records and
by individual selections in the pens. If
this precaution is neglected and the rec
ord only Is relied upon, there is grave
danger weak birds viii be used occasion
ally, thus bringing disaster to all future
results. To understand the method sys.
tcmatically. take a sheet of paper, and
well up near the top of the left side
make a small circle the size of a dime.
On the right hand side, two inches from
and parallel to the first circle, make an.
other Over the left circle write "Msle |
Line" and shade this entire circle black;
over the right circle write Female Line"
and leave it entirely unshaded, that is,
white. On the margin of the paper near
the right circle write the word Genera
tion," and under it "lst."
Note the Change in the Shading.
"Second Generation" is represented BY
6 half black and half white circle 1.-THE
black half being nearest the black circle
abovel, placed between the two first cir.
cles at the top of the page. only about a

the solid black circle draw a solid line

been chosen from the group the breed
