Some information on this subject will be found under the head of _breeding Merinoes_, and _improvement of the Long-Wools_. The ram and ewe should be selected from the best specimens of the breed which is to be perpetuated. There are peculiarities of form or appearance in each, which should be carefully observed. A _violent cross_ should never be permitted for the purpose of perpetuation, as suggested under the head of _principles of breeding_, in a previous chapter; such as between those possessing totally opposite properties, as the Merino and long-wools; and there is no conceivable advantage in mixing the middle-wools, South Downs, &c., with either. Lord Western has long experimented on the blending of the Merino and long-wools, through several generations, without any well-defined results, nor is it believed to be attainable. There is no evenness or integrity of character, either in the animal or fleece, from such mixtures; nor is it possible to foretel the character of progeny from these bastard crosses. The general rule, that like begets like, will not hold true here, for the animal comes large or small, with a long or short fleece, fine or coarse, or intermixed; and this, too, is repeated through numerous generations, when the immediate parents exhibit properties altogether unlike the offspring, and which they derive from some remote ancestry. This practice will do to produce lambs for the butcher, as the consequence of a fresh cross is greater stamina and thrift; and it is found that lambs thus bred attain an early and full development. Thousands of such are annually bred on the banks of the Hudson, Long Island, and around our large cities, and in the worst possible way, as the large, coarse ram is used on the delicate Saxon ewe; yet the lambs thrive and command a good price in the market, and the owner is satisfied to pocket the result. But nothing could be more absurd than to propagate from such progeny for any other purpose than to make early and profitable mutton. The mixture of breeds of similar character, is attended with the best consequences. Such was the intermingling of the improved Leicesters with the Cotswold and Lincolnshire, by which their former coarseness was removed; and such was the use of the latter with the Leicesters, when they became impotent and almost worthless, from over-refinement in breeding. Good results have followed the mixture of the South and Hampshire Downs. A marked improvement in the Merino in this country, has been claimed by Mr. Jarvis and several others, from the mixture of the various flocks, which for ages had been kept distinct in Spain; and the same result is known to have followed a similar course with the Rambouillet and Saxon flocks.
