PRECAUTIONS IN USING THIS TEST. 
It must be remembered that sulphuric acid is of an extremely burning 
nature, and that if dropped on the clothes is sure to burn a hole in them ; in 
fact, it is quite ridiculous to see the nice white aprons and jackets of dairy 
students riddled with holes by the careless use of this acid. 
Indeed, with novices it is not an uncommon thing to suck up the acid 
when using the pipette into the mouth, when much spluttering and a fearfully 
sore mouth results. 
A word of warning also in using amyl alcohol, which, although not so 
dangerous, is extremely nauseous stuff to get into the mouth. Beginners, on 
account of the extremely small capacity and bore of thel ¢.c. pipette, are almost 
sure to suck this stuff into the mouth, so that before using the 1 c.c. pipette 
for amyl alcohol it would be well to get into the way by practising with water. 
Clean out the test bottle immediately after using with hot water, and if 
any fat is left in the neck be sure and get it away with a fine brush provided 
for the purpose, or it will affect the accuracy of the next test. 
Comparing the results of the Gerber test with the Chemist’s Gravimetric 
process—say, Adams—we find that the error is very small, merely nominal, 
about ‘O01 per cent. or ‘02 per cent., so that those who use this test can be pretty 
sure of accurate results, the chief feature of this empirical method being 
dependent on the proper graduation of the test bottles.—Farmer and Stock- 
breeder. 
THE STRUCTURE OF THE COW’S UDDER. 
Te udder of the cow is divided into two chambers by a membrane which runs 
in the same direction as the backbone. So complete is the division resulting 
from the presence of this membrane that the milk from one chamber cannot 
pass into the other. For this reason it is advisable that the milker should 
operate, say, on the front and hind teats on the side next to him, and, having 
emptied one chamber of the cow’s vessel, should proceed with the other. This 
is not, however, the general practice. It is customary to operate on the teats 
of different chambers simultaneously, on the ground that that method of 
procedure preserves the natural state of the udder, whereas such a contention 
is quite contrary to facts. These were some of the points upon which the 
instructor to the Bute County Council recently dwelt with particular emphasis 
in a lecture delivered at a meeting of dairy farmers which he attended in that 
part of the county.— Harmer and Stockbreeder. 
PIG BREEDING AND FEEDING. 
So many of our farmers and would-be farmers are now turning their attention 
towards pig-breeding that too much practical information on the subject 
cannot be given. We know that there is money in dairy-farming and pig- 
raising combined ; and although those already in the business may understand 
it thoroughly, there are others who need a few hints, and we therefore 
republish a chapter from Professor Henry’s excellent book, ‘feeds and 
Feeding,” on the management of pigs :— 
FEEDING BROOD SOWS AND YOUNG PIGS. 
In the successful management of breeding stock the prime requisite is 
ample pasture, that the animals may be’ maintained in the open air and 
sunshine, away from pens and yards, during as large a portion of the year as 
possible. Roaming in pastures covered with nutritious clovers and grasses, the 
pigs will develop healthy bodies. The pasture will not alone suffice
