Mr. L. F. Allen, of Black Rock, N. Y., commenced breeding in 1835, from stock obtained from the Hon. James L. King, of New York, whose father imported them about the year 1819, from the herd of the Earl of Leicester; in 1842 he added to his herd from Mr. Patterson's stock. In 1844 the Massachusetts Society for the Promotion of Agriculture imported four cows and one bull, Bloomfield (372), from the Earl of Leicester. They were boarded and bred for the Society on the farm of Elias Phiney, of Lexington, till his death, the object being to present a pair to each of the County Societies in the State. In 1848, Mr. C. S. Wainwright, of Rhinebeck, N. Y., commenced importing and breeding his herd; his first importation was the bull Megunticook (251), and the cows Nonpareil (924), and Helena (774); Helena gave as high as twenty-two quarts of milk per day, and made fifteen pounds of butter per week. In 1851 he imported May Boy (71), whose granddam, Old May Flower, made over seventeen pounds of butter per week. In 1853, Mr. George Vail, of Troy, N. Y., imported one bull and two heifers from the herds of Mr. Davy and the Earl of Leicester. In 1850 and '52, Col. L. G. Morris, of New York, imported animals from the herds of the Earl of Leicester, the Messrs. Quartly and John Ayer Thomas. Abijah Catlin, of Conn., imported in 1851, Rubens (116), and two heifers. Many others have imported animals equally meritorious, among whom may be mentioned, Ambrose Stevens, of Batavia, N. Y., E. G. Faile, West Farms, N. Y., R. Linsley, West Meriden, Conn., R. W. Sanford, Orwell, Vt., E. P. Beck, Sheldon, N. Y., and R. H. Van Rensselaer, of Morris, N. Y. Importations have occurred almost annually up to the present year. These importations, with many others not mentioned, are sufficient to form the basis of a superior race of Devons in America, not excelled by those in any other country. _Devon Herd Book._ The _First Herd Book_ of the Devons was published in 1851, by John Tanner Davy, of Rose Ash, near Southmolton, Devon, England. The pedigrees of 132 bulls and 483 cows, in all 615 animals, were recorded; all bred in England, and contributed by thirty-seven different breeders. The _second volume_, published in 1854, contained the pedigrees of 221 bulls and 657 cows, 837 animals in all; and was edited by Mr. Davy, in England, and Sanford Howard, in America, comprising animals bred and owned in both countries, sixty breeders contributing in England, and eighteen in America. The _third volume_ was published in 1859, on both sides of the Atlantic, by Messrs. Davy and Howard, independent of each other, Mr. Davy's third volume recorded 204 bulls and 609 cows, in all 810 pedigrees, from forty-one different herds in England, and eight in America. Mr. Howard's recorded 258 bulls and 399 cows, in all 657 pedigrees, from eighty-four different herds, and all from America.
