from observations made on minerals, and it is in the study of the mineral kingdom that the laws of isomorphism and dimorphism find abundant demonstration. From the further investigation of the chemical nature of minerals we may hope for new light on the molecular constitution of substances which as yet the chemist has been unable to reproduce. We have already indicated the interdependence of geology and mineralogy. May we not claim the same interdependence of mineralogy, physics, and chemistry, letting each go on in its own sphere, contributing to the general progress, sure that every new fact observed and every new law discovered will be for the common advancement of all?

THERE is a growing feeling among the students of industrial problems that our whole conception of education in general, and of industrial training in particular, needs revision and enlargement. This feeling is based upon such easily observed facts as the following:

1. Paupers are on the increase.

2. Our schools too often educate their pupils out of harmony with their environment, thus justifying the charge that education (falsely so called) unfits its possessors for useful industry.

3. The simpler and less important positions in the world's work-shop are as a rule greatly overcrowded, while in the upper stories there is a vast amount of unoccupied space.

4. The work done in the lower stories is often exceedingly shabby.

5. Many who aspire to the upper stories fail to enter—or, if they apparently enter, soon end in failure.

6. The chosen few who truly enter, and build up magnificent industrial fabrics, with the splendid fortunes which such fabrics imply, fail to educate their children to carry on their good work, or to do work of similar value in some other department of useful industry.

7. A whole community of prosperous workmen may be well-nigh reduced to beggary by the incoming of some new invention, or by change in the fortunes or tastes of consumers.

8. When old industries are swept away, and new ones established on the wrecks, there is usually little power on the part of workmen to adapt themselves to the new conditions.

9. The relentless law of the survival of the shrewdest and most unscrupulous, instead of the Christian law of mutual consideration and
