In using it, the hind leg is hooked in from behind the sheep, and it fills up the narrow part beyond that point, while passing along it until it reaches the loop, when the animal is caught by the hook, and when secured, its foot easily slips through the loop. Some caution is required in its use; for, should the animal give a sudden start forward to get away, the moment it feels the crook, the leg will be drawn forcibly through the narrow part, and strike the bone with such violence against the bend of the loop as to cause the animal considerable pain, and even occasion lameness for some days. On first embracing the leg, the crook should be drawn quickly toward the shepherd, so as to bring the bend of the loop against the leg as high up as the hock, before the sheep has time even to break off; and being secure, its struggles will cease the moment the hand seizes the leg. No shepherd should be without this implement, as it saves much yarding and running, and leads to a prompt examination of every improper or suspicious appearance, and a seasonable application of remedy or preventive, which would often be deferred if the whole flock had to be driven to a distant yard to effect the catching of a single sheep. Dexterity in its use is speedily acquired by any one; and if a flock are properly tame, any one of its number can be readily caught by it at salting-time, or, generally, at other times, by a person with whom the flock are familiar. It is, however, at the lambing-time, when sheep and lambs require to be so repeatedly caught, that the crook is more particularly serviceable. For this purpose, at that time alone, it will pay for itself ten times over in a single season, in saving time, to say nothing of the advantage of the sheep. DRIVING AND SLAUGHTERING. DRIVING. Mutton can be grown cheaper than any other kind of meat. It is fast becoming better appreciated; and, strange as it may seem, good mutton brings a higher price in our best markets than the same quality does in England. Its substitution in a large measure for pork would contribute materially to the health of the community. Winter fattening of sheep may often be made very profitable and deserves greater attention, especially where manure is an object; and the instances are few, indeed, where it is not. In England, it is considered good policy to fatten sheep, if the increase of weight will pay for the oil-cake or grain consumed; the manure being deemed a fair equivalent for the other food--that is, as much straw and turnips as they will eat. Lean sheep there usually command as high a price per pound in the fall as fatted ones in the spring; while, in this country, the latter usually bear a much higher price, which gives the feeder a great advantage.
