Cows are usually milked three times a day over the greatest part of Scotland, from the time of calving till the milk begins to dry up during the Winter season, when the Cows are for the most part in calf; nor is it found that they suffer by that practice in any degree: and it is the general opinion of all who adopt it, that nearly one third more milk is thus obtained than if they were milked only twice. A Cow, mentioned by Dr. Anderson in his 'Recreations,' (vol. v, p. 309,) was milked three times a day for ten years running, during the space of nine months, at least, every year; and was never seen, during all that period, but in very excellent order, although she had no other feeding than was given to the rest of the Cows, some of which were very low every winter, when they gave no milk at all. A farmer of the name of Watkinson had a Cow that, for seventeen years, gave him from ten to twenty quarts of milk every day; was in moderate condition when taken up, six months in fattening, and being then twenty years old, was sold for more than L18. Mr. John Holt, of Walton, in Lancashire, had a healthy Cow-calf presented to him, whose dam was in her thirty-second year, and could not be said to have been properly out of milk for the preceding fifteen years. Yorkshire Cows, which are those chiefly used in the London Dairies, give a very great quantity of milk. It is by no means uncommon for them, in the beginning of the Summer, to yield thirty quarts a day; there are rare instances of giving thirty-six quarts; but the average measure may be estimated at twenty-two or twenty-four quarts. [Illustration: Alderney Cow, after Howitt.] BUTTER. The Alderney Cow, considering its voracious appetite, yields very little milk; that milk, however, is of an extraordinary excellent quality, and gives more butter than can be obtained from the milk of any other cow. John Lawrence states that an Alderney Cow that had strayed on the premises of a friend of his, and remained there three weeks, made 19 lbs. of butter each week; and the fact was held so extraordinary, as to be thought worthy of a memorandum in the parish books. The milk of the Alderney Cow fits her for the situation in which she is usually placed, and where the excellence of the article is regarded, and not the expense.
