It is natural to want to know the name of any plant that interests us, and this is important. As in the subjects of Birds, there are many helpful books on Flowers and Ferns. Beginners will find "The Flower Guide," by Chester A. Reed (Doubleday, Page & Co.) to be useful. After a good start has been made, such books as Gray's _Manual_, or Britton and Brown's _Illustrated Flora_ should be used. Our pursuit, however, should not stop with the name of a plant. That is a mere beginning. Even slight attention will uncover many fascinating things in the lives of plants. Why cannot a farmer raise a good crop of clover-seed without the bumble-bees? What devices are there among the Orchids to bring about cross-pollination? (See "Our Native Orchids," by William Hamilton Gibson). Examine the flower of the wild Blue Flag, and see whether you can determine how the bumble-bee cross-pollinates this plant. Do the Hummingbirds cross-pollinate some flowers? In what plants is the pollen scattered by the wind? Do these plants produce nectar? [Illustration: GAILLARDIA OR BLANKET-FLOWER Daisy family. Range: Hills and plains of western United States and Canada. Photograph by Albert E. Butler.] How do the various plants scatter their seeds? How are the Hickory-nuts and Walnuts scattered? The Dandelion's and Thistle's seeds have flying-hairs or parachutes and are blown about by the wind. What other plants can you find whose seeds are scattered in the same way? Can you discover a plant whose seeds are carried by water? The Witch-hazel shoots its seeds. What other plants can you find that have explosive fruits? Cherry-seeds are carried by birds. Mention some other seeds that are carried in this way. It would take very little observation to learn how Burdock-burs, Cockle-burs, Stick-tights, Beggar-lice, Spanish-needles, and such hooked fruits are scattered.

Clyde Fisher.] Learn the names of the principal noxious weeds of the farm and garden, and also learn the best methods of combating them. Learn to know the plants in your vicinity which are used in the making of drugs. [Illustration: LOCO-WEED A poisonous plant which produces loco-disease in cattle, sheep, and horses that eat it. Range: Plains from Montana to Colorado. Photograph by Albert E. Butler.] Learn to know the poisonous plants around your home and summer camp. Are the following to be found there: Poison Ivy, Poison Sumach, Loco-weed, Bittersweet (_Salanum Dulcamara_), Black Nightshade, Jimsonweed, Poke-weed, Poison Hemlock?
