By plotting the path of scientific educational progress from earliest times to the present we shall find its movement has been centripetal--from the orbit of the farthest planet to the work of the newest discovered microbe. Astronomy was an exact science long before chemistry had become distinguishable from charlatanry. Each progressive step is one by which some fact is developed affording us a clearer insight into our surroundings, giving us more exact knowledge of how we stand related to the soil, atmosphere, and plants. If we compare the few who now pursue astronomical study with the members who study matters closer at hand it will show us the mighty change in educational ideals from the past to the present. Manual training in the high school is here, agriculture even in the common school is coming. We say to ourselves at our clubs and conventions that "we teachers" have ac...
