Another item to be considered in this connection, is the comparative value of the stock, the forage fed to them, and the _labor_ expended in feeding and taking care of them. We will illustrate: Suppose a farm to lie in the vicinity of a large town, or city. Its value is, perhaps, a hundred dollars an acre. The hay cut upon it is worth fifteen dollars a ton, at the barn, and straw, and coarse grains in proportion, and hired labor ten or twelve dollars a month. Consequently, the manager of this farm should use all the economy in his power, by the aid of cutting-boxes, and other machinery, to make the least amount of forage supply the wants of his stock; and the internal economy of his barn arranged accordingly; because labor is his cheapest item, and food the dearest. Then, for any contrivance to work up his forage the closest--by way of machinery, or manual labor--by which it will serve the purposes of keeping his stock, is true economy; and the making, and saving of manures is an item of the first importance. His buildings, and their arrangements throughout, should, on these accounts, be constructed in accordance with his practice. If, on the other hand, lands are cheap and productive, and labor comparatively dear, a different practice will prevail. He will feed his hay from the mow, without cutting. The straw will be either stacked out, and the cattle turned to it, to pick what they like of it, and make their beds on the remainder; or, if it is housed, he will throw it into racks, and the stock may eat what they choose. It is but one-third, or one-half the labor to do this, that the other mode requires, and the saving in this makes up, and perhaps more than makes up for the increased quantity of forage consumed. Again, climate may equally affect the mode of winter feeding the stock. The winters may be mild. The hay may be stacked in the fields, when gathered, or put into small barns built for hay storage alone; and the manure, scattered over the fields by the cattle, as they are fed from either of them, may be knocked to pieces with the dung-beetle, in the spring, or harrowed and bushed over the ground; and with the very small quantity of labor required in all this, such practice will be more economical than any other which can be adopted. It is, therefore, a subject of deliberate study with the farmer, in the construction of his out-buildings, what plans he shall adopt in regard to them, and their fitting up and arrangement. With these considerations before us, we shall submit such plans of barn structures as may be adapted for general use, where shelters for the farm crops, and farm stock, are required; and which may, in their interior arrangement, be fitted for almost any locality of our country, as the judgment and the wants of the builder may require.
