Young strong shoots which jM- tend horizontally are hest, since on these leaves are most fully deve^^i and their distribution along the twig appears most clearly. Other good kinds of leaves wifc which to begin the stum, if elm leaves are BW" available, are those of beech, oak, willow, peach, cherry, apple. Most of the statements and direc- tions above given would apply to any of the leaves just enumerated. If this chapter is reached too eai;ly in the season to admit of suitable material being procured for the study of leaf arrangement, that topic may be omitted until the leaves of forest trees have sufficiently matured. 97.
