THE DAIRY.

Aerating Milk. , The system of aeration, of cooling milk by air, as it passes through the milk, cools every drop and removes all the odors and gases. When we surround milk with ice and cold water, we reduce the temperature before the animal heat and gas has been displaced from the milk. Ho soon as the milk gets back to the temperature of the outsiac air, the gasses re-act and rapid fermentation soon spoils the milk. Never apply cold water or ice to milk until it has first been aerated. This great invention of "aerating milk not only removes the heat, odors and gasses, but will largely neutralize the bad effects of impure water or impure food. If milk were properly aerated before being taken Into the system, the liability of sickness from that cause wanld be removed.— Grange Hornet
