THE JERSEY, ALDERNEY AND GUERIsTSEY COW. 95 



will vary according to the mirror. There are times 

 when the udder of a cow mirrored like fig. 20 will be 

 enlarged by non-milking, for the purpose of deception. 

 It is always safer to judge by the mirror rather than by 

 the large size of the udder. 



The mirrors of the best cows — those yielding the 

 most and continuing the longest — ^will be found to be 

 those which conform to fie. 18. 



The vertical mirror of fig. 1 7 would not injure it ; but 

 if that ornamental feature has to be at the expense of 

 the thigh mirror, fig. 18 is better as it is. 



Whenever a good mirror is accompanied by a curl 

 on each hind quarter of the udder, it indicates a yield 

 of the highest order. 



These remarks apply with equal force to heifers and 

 bulls, except that the vertical mirror with bulls never 

 extends so high. In heifers and young bulls the mirror 

 is distinctly seen at any time after one month old, and 

 is precisely the same that it will be when the animal is 

 mature. 



So far we have noticed only the rear mirror, or that 

 which represents the two hind-quarters of the udder. 

 The two front-quarters are just as important, and should 

 be capacious, and run well forward under the body 

 (see A). If the udder in front be concave, or cut up, as 

 in B, indicating small capacity, it represents reduced 

 yield. ^ This front or level mirror is distinctly marked 

 in the young heifer or bull, and can be seen by laying 

 the animal on its back. The udder hair under the body
