The Maple Leaf. — Sketch the leafy the leaves arranged in rows like those of the elm ? How arethey arranged? How are the petioles distorted from their natural positions tobring the proper surface of the leaf upward toward the light ? Do the edges of these leaves show larger spaces between themthan the elm leaves did, , would a spray of maple intercept thesunlight more or less perfectly than a spray ofelm? Pull off a single leaf and sketch its lowersurface, about natural size. Of the two main parts whose names havealready been learned (blade and petiole), whichis more developed in the maple than in theelm leaf?Describe: (a) The shape of the maple leaf as a settle this, place the leaf on paper, mark thepositions of the extreme points and connectFig. these by a smooth line.
