Most of us are familiar with the yellow water-lily, and have seen its pretty shield-shaped leaves floating upon the surface of some glassy pond, starred with its large, golden flowers. The latter are sometimes five inches across and quite showy. Sometimes entire marshes are covered with the plants. The large seeds are very nutritious, and form an important article of diet among the northern Indians.
