"Give me of your bark, O Birch-tree! I a light canoe will build me, "Lay aside your cloak, O Birch-tree! And the sun is warm in heaven, In the solitary forest, When the birds were singing gayly, In the Moon of Leaves were singing. And the tree with all its branches Of My canoe to make more steady, Make more strong and firm beneath me!" Down he hewed the boughs of cedar, Shaped them straightway to a framework, Like two bows he formed and shaped them, Like two bended bows together. "Give me of your roots, O Tamarack! Of your fibrous roots, O Larch-tree! My canoe to bind together, So to bind the ends together From the earth he tore the fibers, So to close the seams together That the water may not enter, That the river may not wet me!" And the Fir-tree, tall and somber, And he took the tears of balsam, Took the resin of the Fir-tree, Smeared therewith each seam and fissure, Made each crevice safe from water. HENRY WADSWORTH LONGFELLOW. (By permission.) 1. The stem is that part of a plant which rises above ground from the root; it carries, in proper season, the buds, leaves, flowers and fruit. a STEMS OF (a) ROSE, (b) WALLFLOWER, (c) SWEET PEA. 2. Stems of plants vary in form; some round, some have corners, and some are flat. are To see these three different shapes you have only to cut across the stems of a rose, a wallflower and a sweet pea. 3. Stems differ in other ways also. For instance, the stem of a mignonette is soft to the touch, green in color, pulpy, and easily broken. On the other hand, the stem of a young oak is hard, dark in color, and feels drier than the mignonette, while the fibers are so much tougher that it is not so easily broken as the green stem. 4. All stems like that of the mignonette may be called herblike, or, as the proper word is, herbaceous; while those similar to the oak are spoken of as woody stems. Sometimes on one and the same tree may be seen both tough, woody stems and tender, green shoots which are truly herbaceous; but if these green shoots do not die during the winter they become woody the following season. 5. When a twig of freshly cut willow, or of an ash plant, or of any other woody stem, is stripped of its bark, the part that is left feels sticky. This sticky substance is called the sap, and is really the earth food which has been absorbed by the roothairs, and is being carried upwards to the leaves. A young tree is often spoken of as a sapling. By means of the stem, other substances are conveyed downwards from the leaves to the root. 6. Yet another duty of the stem is to support |
