The native country of the apple, though not definitively settled, is generally conceded to be Europe, particularly its southern portions, and perhaps Western Asia: that is, the plant known and designated by botanists as _Pyrus Malus_, for there are other and distinct species in America and Asia which have no claims to having been the source of our favorite orchard fruits. Our own native crab is the _Pyrus coronaria_, which, though showing some slight tendency to variation, has never departed from the strongly marked normal type. The _P. baccata_, or Siberian crab, is so distinctly marked as to be admitted as a species. It has wonderfully improved under culture, and has produced some quite distinct varieties; it has even been hybridized by Mr. Knight, with the cultivated sorts of the common Wilding or Crab of Europe, the _P. Malus_. Pallas, who found it wild near Lake Baikal and in Daouria, says, it grows only 3 or 4 feet high, with a trunk of as many inches diameter, and yields pear-shaped berries as large as peas. The _P. rivularis_, according to Nuttall, is common in the maritime portions of Oregon, in alluvial forests. The tree attains a height of 15 to 25 feet. It resembles the Siberian Crab, to which it has a close affinity. The fruit grows in clusters, is purple, scarcely the size of a cherry, and of an agreeable flavor; sweetish and sub-acid when ripe, not at all acid and acerb as the _P. coronaria_.[3] Among the early writers upon the subject of pomology, we find some very crude notions, particularly in regard to the wonderful powers of the grafter, for this art of improving the Wilding by inserting buds or scions of better sorts, and thus multiplying trees of good kinds, was a very ancient invention. Pliny, the naturalist, certainly deserves our praise for his wonderful and comprehensive industry in all branches of natural history. In regard to grafting, which seems to have been well understood in his day, he says, that he had seen near Thuliæ a tree bearing all manner of fruits, nuts and berries, figs and grapes, pears and pomegranates; no kind of apple or other fruit that was not to be found on this tree. It is quaintly noted, however, that "this tree did not live long,"--is it to be wondered that such should have been the case? Now some persons may object to the testimony of this remarkable man, and feel disposed to discredit the statement of what appears so incredible to those who are at all acquainted with the well-known necessity for a congenial stock into which the graft should be inserted. But a more extended knowledge of the subject, would explain what Pliny has recorded as a marvel of the art. The same thing has been done in our own times, it is a trick, and one which would very soon be detected now-a-days by the merest tyro in horticulture, though it may have escaped the scrutiny of Pliny, whose business it was to note and record the results of his observations, rather than to examine the modus of the experiment.
