Provide bottles, which must be perfectly clean, sweet, and dry: draw the milk from the cow into the bottles, and as they are filled, immediately cork them well up, and fasten the corks with pack-thread or wire. Then spread a little straw at the bottom of a boiler, on which place bottles with straw between them, until the boiler contains a sufficient quantity. Fill it up with cold water; heat the water, and as soon as it begins to boil, draw the fire, and let the whole gradually cool. "When quite cold, take out the bottles and pack them in saw-dust, in hampers, and stow them in the coolest part of the house. Milk preserved in this manner, and allowed to remain even eighteen months in the bottles, will be as sweet as when first milked from the cow.
