Were all details entered into, a volume could be written concerning this old quarry and the many happy hours spent there, but I will not burden my readers with further reminiscences of my favorite haunt. Berton Mercer. CARNIVOROUS PLANTS. This name has been given to certain plants which have developed the curious habit of capturing insects and using them for food. This behavior seems at first sight most unplantlike, but it is discovered that the actual food of all plants is practically the same as that of animals. The chief peculiarity of carnivorous plants, therefore, does not lie in the food which they use, but in the methods which they have worked out for securing it. They are all green plants, and hence are able to make food for themselves, but they live in surroundings which are poor in some of the material which they need in the manufacture of food, so that they have learned to supplement their food by capturing insects or other small animals. When it was discovered that these plants not only captured insects, but secreted substances for digesting them, it was thought to be a very astonishing fact. It is found, however, that all plants have digestive substances to act upon their food materials, and that animals are not peculiar in this regard. It would seem, therefore, that the use of such food as the bodies of insects and the digesting of this food are not facts which are peculiar to carnivorous plants, but belong to all plants as well. It is interesting, however, to observe the various devices which plants have adapted for capturing their prey, and it is these various devices which form the subject of this paper.
