This will be lost on an ill-shaped, unthrifty beast. The perfection of form and health, and the uniform good condition, which characterize the thrifty one, indicate too plainly to be misunderstood, those which will best repay the care of their owner. The selection of any indifferent animal for stall-fattening, whether cattle or sheep, will inevitably be attended with loss. Such ought to be got rid of when first brought from the pasture, for the most they will bring. Management of Sheep for the Prairies. When destined for the prairies, sheep ought to commence their journey as early after shearing as possible. They are then disencumbered of their fleece, and do not catch and retain as much dust, as when driven later. Feed is also generally better, and the roads are dry and hard. Young and healthy sheep should be selected, with early lambs; or if the latter are too young, and the distance great, they should be left and the ewes dried off. A large wagon ought to accompany the flock, to carry such as occasionally give out; or they may be disposed of whenever they become enfeebled. With good care, a hardy flock may be driven at the rate of 12 or 14 miles a day. Constant watchfulness is requisite, to keep them healthy and in good plight. One-half the expense of driving, may be saved by the use of well-trained shepherd-dogs. When arrived at their destination, they must be thoroughly washed, to free them from all dirt, and closely examined as to any diseases they may have contracted, which, if discovered, should be promptly removed. A variety of suitable food and good shelter must be provided, for the autumn, winter, and spring ensuing, and every necessary attention given them. This would be necessary if indigenous to the country; how much more so, when they have just undergone a campaign, to which neither they nor their race have been accustomed! Sheep cannot be kept on the prairies without much care, artificial food, and proper attention; and from a false system of economy, hitherto attempted by many, losses have occurred from disease and mortality in the flocks, sufficient to have made ample provision for the comfort and security of twice the number lost. More especially do they require proper food and attention, after the first severe frosts set in, which wither and kill the natural grasses. By nibbling at the _fog_, (the frostbitten, dead grass,) they are inevitably subject to constipation, which a bountiful supply of roots, sulphur, &c., is alone sufficient to remove. Roots, grain, and good hay; straw, or corn-stalks, pea or bean vines, are essential to the preservation of their health and thrift during the winter, everywhere north of 39°. In summer, the natural herbage is sufficient to sustain them in fine condition, till they shall have acquired a denser population of animals, when it will be found necessary to stock their meadows with the best varieties of artificial grasses.
