Some of the pelargoniums decorate their leaves with horseshoes. All are in the habit of folding their leaves fan-like in the bud. When they grow large these folds straighten out. It is a good thing to be folded up fan-like in the bud; the leaf then takes up less room, and is kept snug and safe until it grows strong enough to care for itself. The pelargonium indulges in large stipules. These are green, leaf-like bodies growing on the leaf stalk where it is attached to the stem of the plant. They fold over the young leaf and protect it; but after the leaf comes out of the motherly arms of the stipules and stands up on a long stem, the work of the stipules is done, and gradually they fade and wither away. [Illustration: [Pelargonium]] Most pelargonium leaves are covered with a fine coat of hairs. In the warm countries where pelargoniums grow wild they need a coat of down to prevent the sun from scorching them. As long as there is plenty of water in the leaves the sun cannot harm them, no matter how warmly it shines; but if it can draw out the water, then the leaf must fade. The coat of hairs for one thing prevents the water from evaporating too rapidly. Thus the pelargonium does not wear its fuzzy coat to protect it from the cold, but from the sun. The hairs also prevent the rain or dew from stopping up the breathing pores of the leaf. Most pelargonium leaves have a habit of using perfumery of one kind or another. They make it themselves out of the food they find in the earth and the air. The rose geraniums we think are particularly successful in this respect. Why do you suppose the pelargoniums perfume their leaves? Perhaps it is to prevent animals from grazing them, for animals do not like to eat strong-scented things, even if to our senses the odor is agreeable. If this _is_ the reason, we are glad the pelargoniums selected a perfume that we can enjoy. We think there may be some such reason for the fragrance of the pelargonium, because plants are never wasteful. They make only what will be useful to them in some way. They love to be beautiful, but are never satisfied unless theirs is a useful beauty. The fragrance of the leaves, however, may be due to some cause and useful for some purpose that we know not of. [Illustration: [Pelargonium]] THE GERANIUM FAMILY. The Geranium People are rather unsettled as to their relatives—or, rather, _we_ are somewhat confused on the subject. Probably the geraniums know all about it, but they will not tell the botanists, so the botanists have to do the best they can by themselves. [Illustration: [Geranium]] Some say the tropæolum belongs to the Geranium Family, and it certainly does bear quite a strong family resemblance to the geraniums.
