It is accident that has the credit of devising the other methods of reproduction, and has taught us how to break off a branch of a tree and plant it in the earth, from seeing stakes, when driven in the earth, take root, and grow. It is in this way that many of the trees are reproduced, and the fig more particularly; which may be propagated also by all the methods previously stated, with the exception, indeed, of that by cuttings. The best plan, however, is to take a pretty large branch, and, after sharpening it like a stake,[1] to drive it to a considerable depth in the earth, taking care to leave only a small portion above ground, and then to cover it over with sand. The pomegranate, too, may be planted in a similar manner, the hole being first widened with a stake; the same, too, with the myrtle. For all trees of this nature a branch is required three feet in length, and not quite the thickness of the arm, care being taken to keep the bark on, and to sharpen the branch to a point at the lower end.
