Besides the crown flocks at Rambouillet, they are found in equal perfection on several other of the royal farms, especially those of Malmaison, Perpignan, Arles, Clermont, and some others. These flocks have been bred for hardy constitution, large carcass, and heavy fleece, and of as much fineness as is consistent with large weights, and as uniform in quality throughout, as possible. Mr. Gilbert, who was particularly familiar with them, says, "almost all the fleeces of the rams, from two years old and upwards, weigh (unwashed) from 12 to 13 lbs.; but the mean weight, taking the rams and the ewes together, has not quite attained to 8 lbs., after deducting the tags and the wool of the belly." The French pound is about one-twelfth heavier than the English; but from the general custom of folding the sheep in France, feeding them in fallows, and wintering them in houses, the fleece becomes very dirty. The loss in washing (fit for manufacturing) is about 60 per cent., so that the clean fleece of the ram will average about 6 lbs., and that of the whole flock something under 4 lbs. The first Importation of the Rambouillets to this Country. This was in 1801, by M. Dellesert, of Paris, for M. Dupont, then in New York, and consisted of four choice rams, only one of which, Don Pedro, reached this country. He was used among the native ewes near Kingston, N. Y., for three years, and then transferred to Delaware, where he effected great improvement among the native flocks. The second was that made by the late Chancellor Livingston, before alluded to. There was another in 1840, by Mr. Collins, of Connecticut, comprising 30 select ewes and 2 rams. All these sheep possessed the characteristics peculiar to the variety as described. A still more recent importation has been made by Mr. Taintor, at the same time with that of the Saxons previously mentioned, consisting of 23 ewes and 3 bucks, variously selected from the choicest flocks of the descendants of the Spanish Merino. The rams, though young, are the most promising animals of their breed, and when full grown, will weigh from 225 to 250 lbs. each. The sire of one was sold the past season for $500. He sheared 23 lbs. of unwashed wool. The ewes measured after they were shorn, from 25½ to 29 inches in height over the withers. The height of the under side of their bodies from the ground, was from 9½ to 12 inches, which is in the proportion of good American Merino sheep. Their weights varied, after shearing, from 124 to 153 lbs. Some of them were quite thin in flesh, the largest especially, which, if in fine condition with her fleece on, would weigh at least 200 lbs. The following is the weight of their fleeces unwashed. The scales used did not mark less than one-quarter of a pound, which will account for the absence of odd ounces.
