Bullocks, in this country, are most advantageously fattened by stall-feeding; a method now brought to systematic perfection.

The following is the result of experience, inserted in the eleventh volume of the "Annals of Agri-culture" as communicated by J. H. Campbell, Esq. of Charlton, in Kent ; who is one of the most judicious and successful graziers in the kingdom. He first remarks, that the quantity of food required to fatten an animal, depends entirely on the thriving disposition, and not in the least on his weight; and then gives the following answers to Mr. Young's queries: 1. One hundred bushels of potatoes, and seven hundred weight of hay, are generally sufficient to fatten any ox that is a tolerable good thriver. 2. Small quantities of potatoes should be given at first ; then increased to one or two bushels per day, but always intermixing the dry food, and regulating the quantity of hay, by the effe6t which potatoes produce on the bowels. There ought to be at least five servings in a day, and according to the quantity an ox can be induced to eat with appetite, he will the sooner become fat, consequently the cheaper, and with more profit. The roots need not be cut, except in the beginning, to entice the animal to eat them; but they should always be fresh and clean. 3. There is no corn or meal necessary, unless it can be had at a moderate price; in which case it would tend to expedite, and consequently to render more profitable the whole of the feeding. Of this nature are brewer's grains, one bushel mixed with a peck of pollard, sometimes pea or bean-meal coarsely ground, given in two divided portions. 4. Cleanliness is a principal requisite in the feeding of cattle : hence not only the mangers, but also the stalls, ought to be kept as clean as possible; and the former should be cleared from dirt and dust, with a blunt-pointed trowel, every morning. After cleansing their stalls, a sufficient quantity of fresh litter should be strewed over; which will invite them to lie down. - Mr. Campbell is of opinion, and we fully agree with him, that rest contributes to fatten cattle much sooner; and likewise that combing and carding their hides, every day, promotes their thriving more than equal to the small portion of time thus consumed. Lastly, he found the greatest difficulty in prevailing upon the people, to whose care the bullocks were committed, to follow strictly his directions, and to abolish the practice of giving them too great portions of food at a time. Thus, the animal frequently becomes disgusted, his appetite is impaired, and the food is wasted. - The hay is to be cut once; or, if not very weighty, twice along, and three times across the truss, so as to be in squares of eight or ten inches: in this state the cattle eat and digest it more readily, while the fattening is considerably expedited.
