The perfect mouth consists of eight cutting or incisorj 
teeth in the under jaw, and none in the upper, with sir 
grinders or molar teeth on each side, both in the upper and 
lower jaw, making a total of thirty-two teeth. At three 
years, the horns are furnished with a wrinkle at their base, 
and every succeeding year they acquire an additional 
-wrinkle; so that after the animal has re'ached its third year, 
its age may at once be ascertained by counting the wrinkles 
or circles at the base of the horns. In some cattle these 
wrinkles are not so apparent as in others; and many un¬ 
principled dealers file down some of the wrinkles when they 
wish to pass off old cattle for young ones, and thus deceive 
those who are unsuspicious of the imposition. But experi¬ 
enced persons may detect the trick by a close examination 
of the horns, as it is hardly possible to perform this un¬ 
worthy trick in so nice a manner as to give the part which 
has been rasped down the natural appearance of the horn.

MANAGEMENT AND FEEDING, ETC., OF CATTLE. 
COW-HOUSES. 
Nothing is more conducive to the health, and consequently 
to the feeding of the animal, than well-aired and ample 
cow-houses. The dimensions of these will depend upon 
the quantity of stock which the farmer may desire to bring 
up for immediate and marketable purposes. Many different 
plans have been adopted in the construction of such build-
