44 THE ROLLER CANARY 
to quite such an extent? He must get rid of all his 
cocks, the choppers for what they will fetch; the hens 
also he cannot keep, and thus all his trouble and expense 
for one whole year have been wasted, and he must put 
his hand deep down in his pocket to start again with 
birds of a good strain. No tour degenerates so much 
as Gluck. 
Water Roll also is as likely to go worse as to become 
better, and is as little to be recommended as a tour to 
breed for. If the breeding cocks are very good stock 
birds, and they are paired up with fair, or even very 
good, hens, we shall nevertheless hear the youngsters 
giving voice to things that will certainly not be pleasant 
hearing. 
BEAUTIFUL BUT DANGEROUS 
For instance, say the old birds had a lulling 
(kullering) hollow, a tour which decided the purchase 
on account of the charm of its delivery. Their tours 
were a good bass, flutes, deep hollow, and also a deep 
lulling, clear on “ou,” no weak watery effect. This 
deep kuller, which is really beautiful and quite arrests 
attention, carries its danger with it, for even with 
suitable hens the youngsters bring out all sorts of weak

Breeders, in whose hands such birds do _ not 
degenerate, gain much both from a material and an ideal 
standpoint ; it certainly rewards an expert to listen to 
birds which sing the hollow in pure kullering or koller- 
ing form, but the goal is only reached by first-class, 
experienced breeders and trainers, for the reason that 
the kollering and kullering tours have all got the water
