Whatever distrust may be attached to these scraps of history, which apparently establish the remote antiquity of the Merino, this much is absolutely certain, that they are a race whose qualities are inbred, to an extent surpassed by no others. They have been improved in the general weight and evenness of their fleece, as in the celebrated flock of Rambouillet; in the uniformity and excessive fineness of fibre, as in the Saxons; and in their form and feeding qualities, in various countries; but there has never yet been deterioration either in quantity or quality of fleece or carcass, wherever transported, if supplied with suitable food and attention. Most sheep annually shed their wool if unclipped; while the Merino retains its fleece, sometimes for five years, when allowed to remain unshorn. This we conceive affords conclusive evidence of long-continued breeding among themselves, by which the very constitution of the wool-producing organs beneath the skin have become permanently established; and this property is transmitted to a great extent even among the crosses, thus marking them as an ancient and peculiar race. The conquest by the Moors of a part of those fine provinces in the south of Spain, so far from checking, served rather to encourage the production of fine wool. They were not only enterprising, but highly skilled in the useful arts, and carried on extensive manufactories of fine woollen goods, which they exported to different countries. After their expulsion in the 15th century, by Ferdinand and Isabella, the Spaniards preserved these manufactures in part, and sedulously cherished their fine flocks; and knowing the incomparible advantage they had in them, their sovereigns, except in a few isolated instances, strictly prohibited their exportation. Exportation of Merinoes from Spain. History asserts that Henry VIII. of England, by permission of Charles V., imported 3,000 Spanish sheep; but of what kind is not mentioned, they having numerous varieties in Spain. If of the true Merino, it will explain the superior quality of the English middle-wools, the Ryeland, South Downs, and some others. The first well-authenticated exportation of the Spanish Merino, was made to Sweden in 1723, by Alstroemer, which solved the problem of their capacity for sustaining their character, on rough fare and in a high northern latitude. Lasteyrie, who wrote fifty years after the experiment had been tried, speaks of their improvement, both in carcass and the quality and quantity of fleece. The next exportation was made to Saxony, in 1765, and consisted of 105 rams and 114 ewes, but from what flocks they were taken, history nowhere mentions. A second exportation to that country was made in 1778, of 110 that were variously selected, from the best flocks in Spain. From these have descended the high-bred, silken-fleeced Saxons, whose wool stands confessedly without a rival.
