338. (i) What is meant by evil uses on the earth. By evil uses on the earth are understood all noxious things in both the animal and vegetable kingdoms, and also in the mineral kingdom. It is needless to enumerate all the noxious things in these kingdoms for this would merely heap up names, and doing this without indicating the harmful effect that each kind produces would not serve the use which this work has in view. For the sake of information a few examples will suffice. Such in the animal kingdom are poisonous snakes, scorpions, crocodiles, dragons, horned owls, screech owls, mice, locusts, frogs, and spiders, as well as flies, drones, moths, lice, mites, in a word, creatures that destroy grasses, leaves, fruits, seeds, meat and drink, and do injury to beasts and men. In the vegetable kingdom there are all malignant, virulent and poisonous herbs, and leguminous plants and shrubs of like character; in the mineral kingdom all the poisonous earths. From these few examples it can be seen what is meant by evil uses on earth. For evil uses are all the things which are opposed to good uses, about which see a preceding section (n. 336).
