The introduction of the Saxons, in great numbers, in 1826, many of which were excessively diminutive and diseased, and their indiscriminate use with our pure-bred Merinoes, was a serious interruption to the career of improvement in many of our flocks. Their mixture with the best Saxons was no further detrimental, than to reduce the quantity of fleece, and, to a certain extent, lessen the peculiar hardiness of the original Transhumantes, which had been fully preserved by their descendants in this country. The use of well-selected Saxon rams with Merino flocks, was extensively practised, and it is still persisted in by many intelligent flock-masters, after twenty years' experience, who are satisfied that they find it for their interest to continue this style of breeding. The animals being smaller, consume less; and they probably produce a quantity of wool in proportion to their food, which, from its improved and uniform quality, commands a higher price in the market. Wherever they are not sufficiently hardy, they can be bred back towards the Spanish Merino standard, by the use of some of the stouter rams. Their natures are intrinsically the same. They are only divergent streams from the same original fountain, and when again united, they readily coalesce and flow onwards, without violence or disorder. The Merino, as might reasonably have been anticipated, when properly managed, has improved from a variety of causes. Though kept scrupulously pure in Spain, they were seldom bred with that refinement of taste or nice judgment, which distinguishes the accomplished modern breeder. Their management was too entirely intrusted to ignorant shepherds or careless agents, to secure that close attention which is essential to improvement. The sheep had to perform a journey of several hundred miles twice in a year, to and from their distant Sierras; and it was absolutely essential that strong animals should be selected for breeding; and to secure this object, those were frequently used which were deficient in the most profitable qualities. They were also closely bred in-and-in, seldom or never departing from a particular flock to procure a fresh cross. Their wild, nomadic life, approaching nearly to that of their natural state, and their peculiarly healthful pasturage, alone prevented a serious deterioration from this cause.
