Good THE ASIATIC CLASS 139 females can rarely be secured from such a male, as brownor black will appear in the surface of the back. Experi-enced breeders sometimes use dark under-colored femalesthat have a slight amount of dark specks or ticking runningup into the web of the feathers of the back in order tointensify or improve the black markings of the flock. Thisshould only be resorted to, however, when the breeder isthoroughly familiar with the breeding tendencies of hisstock, and is a dangerous practice for the amateur, as it islikely to cause an increase of the black in the surface colorof the flock. This class of females, mated to a male withclean back, will produce the best laced saddles on the maleoffspring, while the female offspring will generally be cleanon the back.

See Fig. 50. In mating this variety, the following defects, in additionto those common to the breed (page 134), must be guardedagainst in so far as possible: indistinct contrast between theblack and white; indistinct lacing in hackle of both sexes;too light under color
