It is said that hearing commences on an average two years earlier when the terminal shoot is removed than when it is allowed to remain. The removal of the apex of the stein causes the four branches that are left just below it to ascend obliquely instead of spread- ing horizontally. The year following the tips of these four branches are in turn removed and all but one of their lateral twigs are cut hack (fig. 8). Dur- ing the fifth year new twigs begin to shoot out from the buds on the stumps (fig. 9) and the young tree begins to assume definite form. The pruning is directed so as to secure a symmetrical, well-rounded top (PL I and PI. IV. fig. 2) with the leading branches at regular intervals and rather far apart. Care is taken to prevent the tree from becoming so tall as to make harvesting difficult, the ideal being a height that equals the spread of the foliage. The inner branches are kept well thinned out, so as to in- sure the access of as much light as possible to all the fruit-bearing twigs. The rapidly growing erect shoots, which absorb much of the sap of the tree and bear little or no fruit, are removed, except those that are destined to become the main branches. Branches growing in a horizontal direction or inclined to droop at the end are favored. The yield largely depends upon the attention given points. The superiority in size of tree- and the greater magnitude and regularity of yield shown by the Sfax orchard- as compared with those of other parts of Tunis are largely attributed to the • •lire with which the pruning is done.
