made per acre from the Southdown than from any other breed, upon nine-tenths of the arable land of England, where the sheep are regularly folded, especially where the land is poor.  In 1822, he commenced that agricultural career which won for him such a world-wide celebrity, by taking the Babraham Farm, occupying about 1,000 acres, some twelve miles south of Cambridge.  In a very interesting letter, addressed to the Farmers’ Magazine, about twenty years since, he gives a valuable resume of his experience up to that time.  In this he states several facts that may be especially useful to American agriculturists.  Having decided in his own mind that the Southdowns were preferable to every other breed, for the two properties mentioned, he went into Sussex, their native county, and purchased the best rams and ewes that could be obtained of the principal breeders, regardless of expense, and never made a cross from any other breed afterwards.  Nor was this all; he never introduced new blood into his stock from flocks of the same breed, but, by a virtually in-and-in process, he was able to produce qualities till then unknown to the race, and to make them permanent and distinctive properties.  Now this achievement in itself has an interest beyond its utilitarian value to the agricultural world.  To

is one of the best privileges and pleasures of a well-constituted mind.  But what higher honor can attach to human science or industry than that of taking such a visible and effective part in that creation?—­in sending out into the world successive generations of animal life, bearing each, through future ages and distant countries, the shaping impress of human fingers, long since gone back to their dust; features, forms, lines, curves, qualities and characteristics which those fingers, working, as it were, on the right wrist of Divine Providence, gave to the sheep and cattle upon a thousand hills in both hemispheres?  There are flocks and herds now grazing upon the boundless prairies of America, the vast plains of Australia, the steppes of Russia, as well as on the smaller and greener pastures of England, France, and Germany, that bear these finger-marks of Jonas Webb, as mindless but everlasting memories to his worth.  If the owners of these “well-created things” value the joy and profit which they thus derive from his long and laborious years of devotion to their interests, let them see that these finger-prints of his be not obliterated by their neglect, but be perpetuated for ever, both for their own good and for an ever-living memorial to his name.
