bewildering, even an overwhelming, variety, without suggestion of order or meaning. While these facts are studied and classified, let the system of the tides be deduced in accordance with accepted physical laws. Let the tidal theory be followed far enough to discover consequences so numerous and so intricate that they cannot be imitated by chance. Neither the inductive nor the deductive work should have precedence. They should advance together, but without confusing one with the other. When both processes are well advanced, let the facts be reëxamined in the light of the theory, and summon a critical judgment to determine how far the reports of outsight and insight agree. Success in such study requires that the facts shall have been closely observed, clearly described, and fairly generalized; the inductive results thus gained being held apart by themselves. It requires, also, that the theory shall have been logically extended to its legitimate consequences; the deductive results thus secured being stored away in a special mental compartment. Then, in due order, bring forth the corresponding members of the two classes of results, and judge of the success of the theory by the agreements thus discovered.

Let the same method be applied in the study of geography. Set an abundant array of facts before the class in the laboratory. Let the facts be examined and classified as far as possible, simply according to their apparent features and without regard to explanation. At the same time, present an outline of a deductive geographical system in the lecture room. During the advance of the two lines of work, compare their results frequently, but do not confuse them. In a few months a large array of facts may be examined, an extended deductive system may be developed, and the two may be compared in the most thorough manner. Every comparison aids further advance in both parts of the work. Both outsight and insight are cultivated. A geographical understanding, based on a proper combination of many mental faculties, is aroused and strengthened. The real study of geography is well begun. The several steps involved in this plan of work may now be traced in some detail.
