[157] Accordingly, many husbandmen at the commencement of the spring watch their young trees, in order at once to destroy whatever fruit they show before it gets to any growth or comes to any size, from fear lest, if it be suffered to remain on, it may bring weakness to the parent tree. For it might happen, if some one did not take care beforehand, when the tree ought to bring fruit to perfection, that it will either bear none at all, or not be able to ripen any, being completely weakened by having been allowed to satiate itself with bearing before its proper time, just as old vine-stems when weighed down, are exhausted both in root and trunk.
