The range of climate in which the native sweet chestnut thrives is quite extensive, as it is found sparingly in Maine in latitude 44°, extending westward,--but not very abundant on this line,--through New England and New York, crossing the Niagara river, skirting the north shore of Lake Erie in Canada, and thence into southern Michigan, but does not reach Illinois. From this line southward it increases in abundance in Virginia, western North Carolina and eastern Tennessee and Kentucky. But in following this tree southward we meet another indigenous species, widely known as the chinquapin (_Castanea pumila_). This species is indigenous to southern New Jersey, and sparingly in parts of Pennsylvania, becoming more plentiful as we proceed southward, the two species named overlapping and in part occupying the same region; but the chinquapin extends further south, and also to the westward, near its northern limits crossing the Mississippi into southern Missouri, then extends south again, becoming quite abundant in Arkansas. The European chestnut, in its many varieties, extends over about the same number of degrees of latitude in Europe as our species do here, although reaching a higher latitude in countries bordering on the Atlantic, as shown in the old chestnut trees of England. The Oriental chestnut has also a very wide range, but the limits are not so well known as those of the European and American species; but a study of its geographical distribution is of considerable importance, now that we are importing these nuts for cultivation. The same is also true of the European varieties, and the cultivator who neglects to take this matter into consideration will fail to secure whatever advantages may have accrued from acclimation, an agency which, undoubtedly, has been active and continuous in modifying and changing the primary characteristics of these plants during unknown ages. To more fully impress upon the reader the importance of care in the selection of materials to be employed in any pursuit with which he is not perfectly familiar, I am prompted to relate the story of my first personal experience in chestnut culture, as it may serve as a warning to others who may attempt to raise these nuts in a cold climate.
