It is a matter for great congratulation that, in the domain of Geomorphology, the scientific research in the true sense of the term concerning exogenic process has become active, especially with Prof. Hjulström's Brobdingnagian effort. Into the surface materials of the earth, however, so little investigation has been done by geomorphologists. In effect, the theory of rock control is not yet awakened from illusion in the prescientific state.
This article accentuates that geomorphologists should exert themselves with all their might to make scientific researches into the dynamic characteristics of the surface materials and into the problems which underlie these characteristics, on the basis of Quantum Theory of matter, Surface Chemistry, Colloid Science Chemistry, Colloid Science and so forth. Such scientific researches not only contribute to the remarkable development of rock control theory, but also they provide engineers with authentic informations and important data.
Finally, the writer advocates that we must give our students fundamental training of the said methods of research. Those professors and researchers who cannot and will not give this training ought to resign from their present positions. Leave their university voluntarily and that at once. That will be their most valuable contribution to the development of the theory of rock control.
