During the autumn another subject for study in this grade is _Mushrooms_. Lead the pupils to see how these flowerless plants produce seed, and let them bring in as many forms as possible. Do not try to teach which mushrooms are poisonous. Lessons with Plants, p. 347; Mushrooms, by Atkinson. _Winter work._--Evergreen trees. Cornell Teachers' Leaflet, No. 13 (No. XXXIII, this volume). _Spring work._--The spring work may well be the making of a calendar for trees and plants. Keep a record each day of the leafage of plants, the appearance of weeds, and the appearance of blossoms of fruit trees and all common flowers. Record which appear first, leaves or blossoms. This work will be good preparation for the study of the "struggle for existence," which comes in the next grade. SEVENTH GRADE. The work for this year, both fall and spring, may be the study of the cross fertilization of flowers. Choose a few of the common flowers, and let the pupils study the means by which pollen is carried from flower to flower. In studying any flower fertilized by insects always ask: Where is the nectary? Where in relation to the nectary are the stigma and the anthers? What path must the insect follow in order to get the nectar? Do the flowers attract insects by color? By fragrance? What insects do you find visiting the flowers studied?

The cross fertilization of flowers is only one adaptation for succeeding in the struggle for existence. Study as many other ways of insuring the continuance of a plant as is possible.

It seems to be the experience of most teachers that pupils of the seventh and eighth grades are with difficulty kept interested in nature-study. This is probably due to the fact that the methods suited to earlier grades are not suited to these. Pupils of this age, now feeling "grown up," are attracted only by more mature work. They may be interested in some of the following subjects: _Horticulture and Gardening._--Cornell Teachers' Leaflets. Garden-Making; The Pruning-Book; The Principles of Fruit-Growing; The Principles of Vegetable-Gardening, all by Bailey. Plant Culture, by Goff. _Forestry._--Relations of forests to preservation of rain-fall and streams. Preservation of Forests. Use of Forests. Reforesting waste lands, etc. A Primer of Forestry by Pinchot, United States Department Agriculture. A First Book of Forestry, Roth.
