Even wood that will have to be removed later may be allowedto remain wholly or partly on the tree for several years. If the tree is a variety that has an upright habit every effortshould be made to direct the growth outward by favoring those later-als which are most nearly horizontal and by heading in more severelythose which point upward. The tendency cannot be entirely changedof course, but it may be more or less corrected. If the tree is a spraw-ly one, it may be necessary to train it up rather than ^ The tree shown on piise 10 pruned. Pruning of Mature Trees.—The problem in pruning a maturetree is to keep it low and spreading b} annual heading-in of the growthsthat tend to go too high, to free the tree of dead and badly insect in-fested and diseased wood, to maintain a fair amount of bearing woodthroughout the whole tree, and to keep the smaller twigs and brancheswell thinned out. By keeping the top low, the fruit is grown andharvested with greater ease and economy. By spreading it out, morewell colored apples can be produced because there is greater space ex-posed to the sunlight. Unless the brush is thinned out and the treeopened up, the death of the inside and lower fruiting wood will buds need light in abundance in order to form and to continue II their work and existence. A tree that is thick with twigs will be fullof wood that is barren of buds of any kind. Such wood is of no useand is in fact a detriment to the tree. In taking out the thickly gro
