Possibly, then, the problem of developing anorange resistant to cold—one that may be grownnot merely along the Gulf but along the GreatLakes as well—may be solved in similar seems paradoxical to suggest that the blendingof oranges from half a dozen tropical and sub-tropical climates—India, Arabia, Northern Africa,Brazil, Florida, Southern California—might pro-duce a fruit adapted to the climate of, let us say,Missouri or Ohio; yet the case of my early plum,descended from late ancestors, suggests that thisidea is not altogether chimerical. This work willbe greatly simplified by the fact that we now havean orange, before mentioned, which, withoutspecial selection for this purpose, is now hardy asfar north as Philadelphia.
