We find that trees in a state of nature always produce their first flowers from lateral branches, to which the sap flows less abundantly than to those which are vertical; and the object of training may be said to be, to give all the parts of a tree the character of lateral branches. With a view to this, certain rules have been derived from the principle of the suppression of the sap, which it may be useful to notice as of general application to every mode of training: — 1. Branches left loose, and capable of being put in motion by the wind, grow more vigorously than those which are attached; and hence the rule to nail or tie in the stronger shoots first, and to leave the weaker shoots to acquire more vigor. Hence, also, the advantage of training with fixed branches against walls, as compared with training with loose branches in the open garden, when greater fruitfulnesa is the object. 2. Upright shoots grow more freely than inclined shoots. Therefore, when two shoots of unequal vigor are to be reduced to an equality, 50.
