THE CRESTED CANARY 277 thing easily accounted for on the hypothesis tiiat the recognised form of Crest has much of the Plainhead in it, and we have seen more or less disturbance of the usual type, but never anything remotely approaching baldness—in fact, always the reverse. And further, among the thousands of crests we have seen of all conceivable styles, bred, doubtless, in all sorts of ways from Crest and Plainhead, and, for want of better knowledge, frequently enough from re- peated successions of double Crests, we never remember seeing a head so bald as tills defect disa})pears from the offspring if such birds are paired to Crestbreds. Dealing with general principles, we say, as a second thing to be observed, that whereas in breeding Norwich Plainheads two Yellows are sometimes paired to obtain colour even at a probable sacrifice of featlicr, so, in breeding for crest, double Buffs are paired to get or thicken the feather at the expense of colour, and the latter practice has been carried on to too great an extent, much to the detriment of the colour and quality of feather of Crests, to say.
