Some boys and girls lose interest in collecting plants after the first season, especially if they have done well the first year and secured most of the species in their locality. If the opportunity to collect elsewhere does not come the next spring there can be nothing more interesting than to try to get the same things you already have, but in some other stage of their growth. For example: most collections will have several kinds of violets, blue, white and yellow, in all the beauty of their flowering. But whoever thought of getting one that showed the seed pods? What is a violet's seed pod like anyhow? Is the seed pod of the white one like that of the yellow? Are the seed pods of one plant all alike? When do the pods open and how? How do the seeds germinate and when? These and other questions are waiting to be answered by every plant in your collection. Would it not be fine to know the pure white trillium in midsummer when it has grown a leaf nearly a foot across and has a red fleshy seed case thrust up where it will be conspicuous? Some plants are far more showy in fruit than in flower and you will begin to see why these and other things are true as you carry on your studies throughout the year. Many a teacher of botany is forced to depend upon pictures when she wishes to teach children to discriminate between two kinds of leaves, kinds of roots, kinds of stems, kinds of inflorescence. What a boon to those teachers would be a collection put up to illustrate the lessons as they came along! I wonder if there is not a market for such collections in schools where no herbariums are made or kept. For little children, making blue prints is delightful occupation. I knew a child of four who learned to recognize the leaves of most of the common trees one spring by means of this work, and she did every bit of it alone. A small printing frame, blue print paper of the required size, and plenty of water is all that is required. A child soon learns to use good judgment in printing, exposing the frame just long enough to get a fine blue. The outline of the leaf comes out distinctly in white against a blue background. The prints should be thoroughly washed and may be dried on panes of glass.
