The baby leaves or blossoms, inside winter buds, are often protected, we remember, by horny scales. Some buds have several rows of these, one outside another. When the young leaves awaken and expand in spring, these protecting scales will fall off (Fig. 14) or shrivel away, leaving scars to show where they grew. The traces left by bud scales of past years look as if a strong thread or fine wire had been wound very tightly around the branch, and had cut a little way into the bark. By cou

The traces left by bud scales of past years look as if a strong thread or fine wire had been wound very tightly around the branch, and had cut a little way into the bark. By counting these marks one can tell the age of a small branch; but we cannot trace the record far back on larger boughs, because after awhile the outermost layers of the bark peel away, marks and all. The branch tips, which grew out last spring and are now less than a year old, are always smoother than the more mature parts of the trunk, and generally they are of a different color. Where the bark changes its color, look for the scars showing where the winter bud scales fell away last spring. When the bud scales are few or very small, their slight marks are difficult to find.
