Wild-Flower Study 547 finally decays and the seed falls to the bottom where, if the conditions are favorable, it develops into a new plant. To emphasize the fact that the water lily is dependent upon certain geographical conditions, ask the pupils to imagine a water lily planted upon a hillside. How could its roots, furnished with such insufficient rootlets, get nourishment there? How could its soft, flexible stems hold aloft the heavy leaves and blossoms to the sunlight? In such a situation it would be a mere drooping mass. Moreover, if the pupils understand the conditions in which the water lilies grow in their own neighbor- hood, they can understand the conditions under which the plant grows in other countries. Thus, when they read about the great Victoria regia of the Amazon,—that water lily whose leaves are large enough to support e man,—they would have visions of broad stretches of still water and they should realize that the bottom must be silt. If they read about the lotus of Egypt, then they should see the Nile as a river with borders of still water and with bottom of silt. Thus, from the conditions near at hand, we may cultivate in the child an intelligent geographical Seed vessel oj wliite pond lily. LESSON CXXXII The Water Lily Leading thought—The water lily has become dependent upon certain conditions in pond or stream, and has become unfitted in form to live elsewhere. It must have quiet waters, not too deep, and with silt bottom. Method—The study should be made first with the water lilies in a stream or pond, to discover just how they grow. For the special struc- ture, the leaves and flowers may be brought to the schoolroom and floated in a pan of water. The lesson may easily be modified to fit the yellow water lily, which is in many ways even more interesting, since in shallow water it holds its leaves erect while in de
