Sometimes a great many of these factories of one kind are together, and then the air is filled with the perfume they make. You will at once think of a clover-field. How sweet the fragrance as the wind blows over the field and brings it to you! All this perfume comes from millions of little factories. For each clover-head is a perfume-factory, as you may know if you pick one and smell it.

Grape-vine.

The fragrance from the flowers of the grape-vine is very delicious. It is of this that Solomon speaks when he says, “The vines with the tender grape give a good smell.” When the grape-vines are in bloom the air is filled with their fragrance; and yet the flowers are so small, and so near the color of the stem and the leaves, that you would not notice them, unless you looked particularly for them.

Unpleasant odor of some plants.

There are some flowers that have an unpleasant odor. Sometimes this is because they are poisonous, the odor making us avoid them, and thus saving us from danger. But in many cases we can not see any such reason for the unpleasant odor. Why it is that such a splendid flower as the crown imperial should smell so disagreeable we do not understand. One thing, however, is true: the bad-smelling plants are few, while God has given us a multitude of those that smell sweet.

Questions.—What else in the flower, besides color, is made from the sap? Is the perfume in the stem? Where is it made? Mention some flowers that have a strong smell. Mention some that are very handsome, and yet have no fragrance. Mention some that have both fragrance and beauty. What is said about the different odors of flowers? How does this show the goodness of God to us? Tell about the clover-field. What is said of the flowers of the grape-vine? What is said of flowers with a bad odor?
