Summary of methods.—The observations may be made in the schoolroom or out-of-doors. There should be observations of experiments in spraying. This may be accomplished in most localities by encouraging the pupils to visit orchards undergoing the operation of spraying. However, by means of syringe or watering pot, the infested plants brought into the schoolroom may be sprayed and the results noted. Lessons should be given on the importance of preserving insect friends while we are destroying insect enemies.
