Examine a sprig of elm and notice further that the flower buds are all down near the base of the stem, while the leaf buds are near the tip. The chief development of the season's growth is thus thrown toward the end of the branch, giving rise to that fine, feathery spray which makes the elm an even more beautiful object in winter than in summer. An examination of the twigs of other trees will bring out the various peculiarities that affect their mode of branching. The angle, for instance, which a twig makes with its bough has a great effect in shaping the contour of the tree. As a general thing, acute angles produce slender, flowing effects ; right, or obtuse angles, more bold and rugged outlines. PRACTICAL QUESTIONS 1. Has the arrangement of leaves on a twig anything to do with the way a tree is branched? (68, 241.) 2. Why do most large trees tend to assume the excurrent, or axial mode of growth if let alone? (244.) 3. If you wished to alter the mode of growth, or to produce what nurserymen call a low-headed tree, how would you prune it? (246, 247.) 4. Would you top a timber tree? (246, 247.).
