Reseña del editor

Since the seedling plant is useful in illustrating several of the life processes of plants we may well begin with some studies of germinating seeds. We may take for the first example the pumpkin seedling, and then follow with several others in order to become familiar with the parts of the seedling plant before ,re, study the life processes. THE PUMPKIN SEEDLING. Demonstration I. 2. To prepare seeds for germination. Soak(a handful of seeds (or more if the class is large) in water for twelve to twenty-four hours. Take shallow crockery plates, or ordinary plates, or a germinator with a fluted bottom. Place in the bottom some sheets of paper, and if sphagnum moss is at hand scatter some over the paper. If the moss is not at hand, throw the upper layer of paper into numerous folds. Thoroughly wet the paper and rr oss, but do not have an excess of water. Scatter the seeds among the moss or the folds of the paper. Cover with some more wet paper and .in a room where the temperature is about 20 C. to 25 C. The germinator should be looked after to see that the paper does not become dry. 5may be necessary to cover it with another vessel to prevent the too rapid evaporation of the water. The germinator should be started about a week before the seedlings are wanted fer study. Some of the soaked seeds should be planted in soil in pots and kept at the same temperature, for comparison with those grown in the germinator.
