The first importation of Merinos into the United States took place in 1801; a banker of Paris, Mr. Delessert, having shipped four, of which but one arrived in safety at his farm near Kingston, in New York; the others perished on the passage. The same year, Mr. Seth Adams, of Massachusetts, imported a pair from France. In 1802, Chancellor Livingston, then American Minister at the court of Versailles, sent two choice pairs from the Rambouillet flock—which was started, in 1786, by placing four hundred ewes and rams, selected from the choicest Spanish flocks, on the royal farm of that name, in France—to Claremont, his country-seat, on the Hudson river. In the latter part of the same year, Colonel Humphreys, American Minister to Spain, shipped two hundred, on his departure from that country. The largest importations, however, were made through Hon. William Jarvis, of Vermont, then American Consul at Lisbon, Portugal, in 1809, 1810, and 1811, who succeeded in obtaining the choicest sheep of that country. Various subsequent importations took place, which need not be particularized.

The cessation of all commercial intercourse with England, in 1808 and 1809, growing out of difficulties with that country, directed attention, in an especial manner, toward manufacturing and wool-growing. The Merino, consequently, rose into importance, and so great was the interest aroused, that from a thousand to fourteen hundred dollars a head was paid for them. Some of the later importations, unfortunately, arrived in the worst condition, bringing with them those scourges of the sheep family, the scab and the foot-rot; which evils, together with increased supply, soon brought them down to less than a twentieth part of their former price. When, however, it was established, by actual experiment, that their wool did not deteriorate in this country, as had been feared by many, and that they became readily acclimated, they again rose into favor. The prostration of the manufacturing interests of the country, which ensued soon afterwards, rendered the Merino of comparatively little value, and ruined many who had purchased them at their previous high prices. Since that period, the valuation of the sheep which bear the particular wool has, as a matter of course, kept pace with the fluctuations in the price of the wool.

The term Merino, it must be remembered, is but the general appellation of a breed, comprising several varieties, presenting essential points of difference in size, form, quality and quantity of wool. These families have generally been merged, by interbreeding, in the United States and other countries which have received the race from Spain. Purity of Merino blood, and actual excellence in the individual and its ancestors, form the only standard in selecting sheep of this breed. Families have, indeed, sprung up in this country, exhibiting wider points of difference than did those of Spain. This is owing, in some cases, doubtless, to particular causes of breeding; but more often, probably, to concealed or forgotten infusions of other blood. The question, which has been at times raised, whether there are any Merinos in the United States, descendants of the early importations, of unquestionable purity of blood, has been conclusively settled in the affirmative.

The minor distinctions among the various families into which, as has already been intimated, the American Merino has diverged, are numerous, but may all, perhaps, be classed under three general heads.

The first is a large, short-legged, strong, exceedingly hardy sheep, carrying a heavy fleece, ranging from medium to fine, free from hair in properly bred flocks; somewhat inclined to throatiness, but not so much so as the Rambouillets; bred to exhibit external concrete gum in some flocks, but not commonly so; their wool rather long on back and belly, and exceedingly dense; wool whiter within than the Rambouillets; skin the same rich rose-color. Sheep of this class are larger and stronger than those originally imported, carry much heavier fleeces, and in well-selected flocks, or individuals, the fleece is of a decidedly better quality.

The second class embraces smaller animals than the preceding; less hardy; wool, as a general thing, finer, and covered with a black, pitchy gum on its extremities; fleece about one-fourth lighter than in the former class.

OUT AT PASTURE.

The third class, bred at the South, mostly, includes animals still smaller and less hardy, and carrying still finer and lighter fleeces. The fleece is destitute of external gum. The sheep and wool have a close resemblance to the Saxon; and, if not actually mixed with that blood, they have been formed into a similar variety, by a similar course of breeding.

The mutton of the Merino, notwithstanding the prejudices existing on the subject, is short-grained, and of good flavor, when killed at a proper age, and weighs from ten to fourteen pounds to the quarter. It is remarkable for its longevity, retaining its teeth, and continuing to breed two or three years longer than the common sheep, and at least half a dozen years longer than the improved English breeds. It should, however, be remarked, in this connection, that it is correspondingly slow in arriving at maturity, as it does not attain its full growth before three years of age; and the ewes, in the best managed flocks, are rarely permitted to breed before they reach that age.
