JOURNAL FREE ACCESSThe dispersed type of rural habitat is rather exceptional in Japanh, where most of the settlements are of the clustered habtat type. A rare example of the dispersed type is found on the alluvial fan of the Ooi-gawa, Sizuoka prefecture. The origin of the present scat-tered habitat is not very old, dating from the great inundations of 1604 and 1627, although the habitat-type of its predecessors on this, fan are unknown. Why did the immigrants who come from surround-ing regions, where the clustered type of habitat prevail, to this, devastated region, without exception prefer the scattered type of habitat? The authors presume that the difficulties of life in such desolate plains forced Them to adopt this type of habitat. Since then, even to this day, it has become the tradition in this region that every dispersed farmer shall cultivate the field around his house.
The authors analyse the minute adaptations of the inhabitants to their environment. The developments of economic and social life in the village commuity, after which they describe the methods of population control and discuss the future continuity of this dispersed type of habitat.View full abstractDownload PDF (2739K) -

JOURNAL FREE ACCESSThe method herein described is based on the principle of shading by oblique illumination. In working out this new method, however, the author investigated theoretically the intensity of light and shade or the configuration of brightness on a surface, and found a way of correctly representing on a map the brightness thus determined, justifying his view that the reasoning of the investigation should be based on realities, and that the method of drawing should be as scien-tific as possible, so that the resulting map may be exact and true to nature.
The process of drawing may be explained with the aid of Fig. 3. The ground is first tinted grey, the contours in the light are then drawn in white, and those in the shade in black. The breadth of the contours, however, varies with the cosine of the angle θ between the horizontal direction of the incident ray and the normal to the contour at the point under consideration. It is shown that the configuration of brightness of the two cases, namely, the actual surface and the map, will resemble each other very closely, if the maximum breadth of the contours may be determined theoretically in terms of the brightness of the ground and of the contours.
The advantages of the proposed method are:
1. The method gives a remarkable effect of relief.
2. The process of drawing is simple and scientific, and involves no ambiguity.
3. The maps afford at a glance a clear idea of the minor featuies, no matter how complicated, they may be, to say nothing of the general character of the country.View full abstractDownload PDF (5634K) -
