PRINCIPLES OF THE GROWTH OF TREES. divided as growth advances, until lost in laterals or side branches. The fibres or rootlets are the small thread-like roots proceeding from the laterals; and lastly, the smallest of all, the new fibres are furnished with root-hairs, scarcely visi- ble without a ^ H ii microscope. The whole surface of roots continue to absorb moisture from the soil so long as they are fresh and new; and the newer p o r- tions, near the tips, absorb m o St freely. Old roots, covered with a hard or hor- ny bark, imbibe almost none. The root-hairs convey mois- ture into the fibres with rapidity. Young trees, when dug up for transplanting, have most of the fibres and root-hairs torn from them, and they would suffer serious injury or die, but for the powv^r which they possess of rapidly reproducing them under favorable influences. The collar is the point of union between the root and the stem, but its place may be easily changed in many young plants by banking up the stem, which will emit new roots above. Or, a branch may be buried, as in layering grape- vines, honeysuckles, gooseberries, and many other woody plants. Small portions of roots attached to a graft will often produce a new plant; this is especially the case with the grape and rose, which are extensively propagated in this way; and also in some degree with the apple, of which, however, when thus root-grafted, larger portions should be employed of the roots of one-year, or at most two-year, Fig. 2.—Root System of Two-year-old Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Thomas, J.
