BIOLOGY SERIES: 
No. i f Biology of the Common Toad, 17 pages, \ illustration, 
1898 and 1899. 
No. 2, Biology of Our Common Birds, 35 pages, 13 illustra¬

This series of leaflets is written distinctively from the point of view of 
human interests in nature. It is prepared primarily for teachers, and also for 
parents and children, who wish to form permanent and mutually helpful 
relations with nature. The chief purpose is to teach in plain, untechnical 
language, the important human values connected with knowing and doing 
something about the common forms of life associated most closely with human 
life and interests. As indicated in the word, Biology , the series is designed to 
bring out life in its wholeness, the larger relations and interrelations between 
living things, the view of an animal or plant as a living force in nature, to 
know and utilize which is the ultimate goal of human knowledge. From this 
point of view, naturally, the things that possess the largest human interests 
will be treated, so far as practicable, in order of their relative importance. 
While each leaflet is complete in itself, in a measure, repetition is avoided 
and a higher unity embodied in the whole series, the plan of which is to give 
abundant material for a course in nature study for the grades and high school. 
Leaflets are prepared, or in course of preparation, on the biology of flowers, 
fruit, nut and forest trees, bacteria and moulds, insects and worms, fishes, bats 
and reptiles. As money returns from their sale, other leaflets will be printed 
as rapidly as possible. Addresses for future leaflets will be filed in order of 
receipt, and mailed as soon as published.
