Among the established breeds of cattle the IMPROVED SHORT-HORNS are the most fashionable, and the most widely diffused; and where the fertility of the soil, and the climate, are such as to allow the development of their peculiar excellencies, they occupy the highest rank as a meat-producing breed. Their beef is hardly equal in quality to that of the Devons, Herefords or Scots, the fat and lean being not so well mixed together and the flesh of coarser grain. But they possess a remarkable tendency to lay on fat and flesh, attaining greater size and weight, and coming earlier to maturity than any other breed. These properties, together with their symmetry and stately beauty, make them very popular in those counties of England, where they originated, and wherever else they have been carried, provided their surroundings are such as to meet their wants. In the rich pastures of Kentucky and in some other parts of the west, they seem as much at home as on the banks of the Tees, and are highly and deservedly esteemed. The Short-horns have also been widely and successfully used to cross with most other breeds, and with inferior mixed cattle, as they are found to impress strongly upon them their own characteristics. Without entering into the question of its original composition, or of its antiquity, regarding both of which much doubt exists, it may suffice here to say, that about a hundred years ago, Charles Colling and others entered zealously and successfully into an attempt to improve them by careful breeding, in whose hands they soon acquired a wide spread fame and brought enormous prices; and the sums realized for choice specimens of this breed from that time to the present, have been greater than for those of any other. Much of their early notoriety was due to the exhibition of an ox reared by Charles Colling from a common cow by his famous bull "Favorite," and known as the "Durham" ox, and also as the "Ketton" ox, (both which names have since then been more or less applied to the breed, but which are now mostly superceded by the original and more appropriate one of Short-horn,) which was shown in most parts of England and Scotland from 1801 to 1807, and whose live weight was nearly four thousand pounds, and which was at one time valued for purposes of exhibition as high as $10,000.
