If possible, get a cicada as these insects continue to sing through the warm days of September. Show the cover to the drums on the lower side of the common cicada. Cornell Nature-Study Bulletin, No. 1, p. 24 (No. VI, this volume). This can be made a most interesting subject, and pupils should be encouraged to do observation work outside of school. Begin a general collection for schoolroom. _Spring work._--Continue making a general collection for the schoolroom, and specialize in this direction. When an insect is brought in and added to the collection, if the teacher knows the insect, a lesson should be given on its life and habits. This connecting of the life and habits of the insects with the collection of dead specimens is of greater value from a nature-study point of view than the collection itself. _Summary of methods._--While this year's work must be based on the observations of the pupils in the schoolroom and out-of-doors, yet many interesting lessons may be given by the teacher. SEVENTH GRADE. The study of this entire year may be the relation of insects to flowers. Most of the references are given in the Plant-life work for this grade. The insect work may be limited to: What insects visit flowers? How do they carry pollen? How does each kind of insect reach the nectar? Which insects are robbers, and which are true pollen carriers? The use of pollen by insects. Outdoor Studies, pp. 7-12. Take up the study of golden rod and its insect visitors, _i. e._, let the pupils watch a bunch of golden rod and note all the insect visitors. For directions concerning this work see Outdoor Studies, pp. 29-46. In the same way take up the study of asters and the late flowers, and their insect visitors. Describe the visitor; what it does; what part of the plant it visits. _Summary of objects and methods._--The object of this whole year's work is to show the beautiful inter-relation between insects and flowers. The studies must necessarily be made in the field. But many delightful lessons may be given on the structure of flowers, that make of greatest use to the flowers the work of insect visitors. EIGHTH GRADE. The object of this year's work is the economic side of insect-study. Many pupils do not continue these studies to high school or college. Yet if they have homes with gardens or trees in city or country, they must learn to cope with the many insect enemies that feed upon cultivated plants. They should also learn to discriminate between insect friends and foes. They should learn the best methods of combating the foes and preserving the friends. Explain first that in fighting an insect enemy we must know how it eats. If it inserts its beak in the stem of the plant there is no use trying to kill it by putting poison on the leaves. COMMON INSECT FOES. To be studied in the schoolroom: _Fall work._--Codlin-moth. Insect Life, p. 180. Show work on an apple, and give methods of destroying it. Plum curculio. Insect Life, p. 182.
