Meshes, each having a side 5mm long, are drawn on the map (1:25000), and the inclination and the area of the cultivated land measured. In this way the relation betwen the inclination and the cultivation was obtained for the western slope of Mt. Hakone and Mt. Asitaka. The former is about 20km SSE of Huzi-san (Mt. Fuji), and the latter about 30km SE of the same mountain. Both are slightly dissected extinct volcanic cones. The slopes are thickly covered with loam. On the western slope of Mt. Hakone the principal cultivation is wheat in winter and batata in summer (Fig. I ). On the southern slope of Mt. Asitaka these two cereals are also cultivated. The settlements are at the foot of the mountains (Fig. 5). We find in this vicinity no farms in terraces. The inclination of the ground and the rate of cultivation are measured on Hakone between the foot of the mountain and a height of 300m and on the slope of. Mt. Asitaka between the foot of the mountain and a line at a distance of 5km from the foot. The results are shown in Figs. 4 and 8. The abscissa and ordinate represent the inclination and rate of cultivation. The approximate curves are represented by probability curves (Formula 2. and 3.). From results we conclude that the rate of cultivation may change its value with the inclination, as both figures show. Further, the relations between the rate of cultivation, the distance, and the height are also here obtained (on the slope of Asitaka), the results being shown in Figs. 9 and 10. The rate of cultivation decreases as the distance from the mountain-foot and the height increases.
The writer drew a distribution map of towns under the guidance of Assistant Professor Tsujimura, using the topographical maps of the Military Survey, scale 1:50, 000. According to his method, each topographical map sheet is divided into 16 rectangles of 28sq. kms each, and the number of towns calculated in each rectangle. We find at once from the resulting map that the distribution of towns stands in close relation to the topographical features; that is to say, it is much denser on wide alluvial and beach plains than on upland areas. We find next that the highest density is in the neibourhood of great cities. Lastly, the writer divided the Kwanto. Plain into three parts in order to explain these relations precisely. (1) Northeastern Kwantô. There are no wide alluvial and beach plains, the whole is upland area, so that the distribution is not dense. It is discontinuous. (2) Southeastern Kwantô (Bôsô Peninsula). Wide alluvial plains do not exist, hence the distribution is zonal in th beach plains. (3) Western Kwantô. There are not a few wide alluvial and beach plains, there are large cities. The density is therefore highest, and the distribution very compact and continuous.
