Sheep, like cattle, should be selected for specific purposes, and in reference to affording the greatest profit under existing, and probable future circumstances. The exclusive cultivation of this or that breed--of the fine or coarse, or of the long or short wools--whether kept exclusively for their wool, or both for their wool and the shambles, should never be practiced, unless under special and unusual circumstances. The farmer in this, as in every other agricultural department, must endeavor to see his relation to the merchant, and adopt a practice having in view the chances of ultimately reaching the most certain as well as the most profitable market; for, after all, the connection between the producer and the manufacturer and merchant, is but a partnership for loss and gain. The merchant will call upon the manufacturer for such woolen goods as his market demands, irrespective of the mere opinion which any one may entertain in favor of this or that kind of wool; and the manufacturer, in his turn, will call upon the farmer for just what is wanted. The farmer should therefore, in the selection of his flocks, have in view the market upon which he is to rely for the sale of his wool; the texture and weight of fleece; the health and vigor of body and constitution, as well as the habits and economy of the animal. He should sedulously seek to bring his sheep to a high degree of perfection in every respect. In seeking to obtain quality of fleece it is a self-evident fact that he should not overlook quantity; and that quantity should also be considered in connection with quality. It is a patent fact, of which if we needed evidence it may be found in this exhibition as well as in the numerous county exhibitions of similar character, which have recently been held, where very rarely any other class of sheep are seen, that a strong preference for fine-wooled Merinos is very generally, if not almost exclusively, entertained at the present time among the farmers of this State, and money in the purchase of that class is of but little account. It is well known that very high prices are being paid not only for single specimens but for whole flocks of this breed. This is probably all right, so far as it is necessary for the purpose of attaining excellence in flocks, upon points already spoken of. To such a preference there should be no objection, if it be not carried so far as to superinduce an unprofitable reaction--and provided that the demand for the grade of wool produced by these sheep is to have no limit, and that all which can be grown is sure always to command a remunerative price. But will this probably be so? Let us consider.
