Its fruits are more common and more popular in American markets than those of any other pear. When the characters of the variety are passed in review, although several poor ones of fruit and tree appear, the popularity of Bartlett with growers and sellers, if not with consumers, seems justified. As with the leading variety of any fruit, the preëminently meritorious character of this one is its great adaptability to different climates, soils, and situations. Thus, Bartlett is grown with profit in every pear-growing region in America and in all is grown in greater quantities than any other sort excepting, perhaps, the notorious Kieffer. Another character which commends this variety to pear-growers is fruitfulness--barring frosts or freezes, the trees bear full crops year after year. Moreover, the trees are very vigorous, attain large size, bear young, live long, are easily managed in the orchard, and thrive on both standard and quince stocks. The pears are large, handsome, of good but not of the best quality, and keep and ship remarkably well.
