LESSON CCVII The Witch-Hazel Leading thought—The witch- hazel blossoms during the autumn, and thus adds beauty to the landscape. It has an interesting mechanism by which it can shoot its seeds for a distance of many feet. Method—This lesson divides naturally into two parts; a study of the way the seeds are distributed is fitted for the primary grades, and a study of the flower for more advanced grades. For the pri- mary grades the lesson should begin by the gathering of the twigs which bear the fruit. These should be brought to the schoolroom—• there to await results. Soon the seeds will be popping all over the schoolroom, and then the question as to how this is done, and why, may be made the topic of the lesson. For the study of the flower and the shrub itself, the work should begin in October when the blossoms are still in bud. As they expand they may be studied, a lens being necessary for observing the interesting little doors to the anthers. Observations—i. Is the witch-hazel a shrub or a tree? 2. What is the color of the bark? Is it thick or thin, rough or smooth, dark or light, or marked with dots or lines ? Is there any difference in color between the older wood and the young twigs? Is the wood tough or brittle? Dark or light in color? 3. Do the leaves grow opposite each other or alternate ? On what part of the plant do the leaf buds grow ? 4. What is the general shape of the leaf ? Is it more pointed at the base or at the tip ? Are the leaves regular in form, or larger on one side than the other? Are the edges entire, toothed or wavy? Are the petioles short or long? A
