We are already familiar with certain papers in which the division of geographical landscape has been treated more or, less fully. For example, those of S. de Geer (1928) in Baltoskandia and J. G. Granö (1929, 1931) in Estnia and Finland. But they, refered also to many other factors, such as the climatological, geological, historical, economical, etc., Lesides the morphological factor in landscape. In this paper the writer treats only of the mo phological factors and attempts a division on that basis of the districts of Mt. Aso and .Mt. Fuji, the two famous and widely known volcanoes of Japan, using a topographical map, scale 1:50, 000 (Fig. 4).
(1) Fig. 1 and Fig. 2 merely show the outlines of the two mountains.
(2) Each of the six figures of Fig. 5 shows respectively a factor on which the division of the landscape (Fig 4) is based; namely the settlements, the rice-fields, the vegetable-fields, the bamboo groves, the grass-lands, and the forests. Any factors of the same kind out of the six just-mentioned and 'variously distributed, are connected by lines in two different ways; at distances 0.5km apart and 1km apart, the first with broken lines and the second with full lines.
(3) In. Fig. 6 are shown the six different factors that have been connected with broken lines (right) and with full lines (left). Where the lines connecting the various factors approach each other in the map, and there are more than four such lines within a distance of 0.5km from each other, the areas are shaded, but when not less than two and not mare than three such' lines approach each other within 0.5km, the area is stippled.
(4) When the foregoing shaded areas are connected with a line, we obtain the boundary of what we may call a geographical province. When a line is drawn through the middle of the stippled area, we then have what we may call a geographical territory. When either the broken lines or the full lines (Fig. 16) intersect and bound-an area not more than 0.5km apart, we may regard the lines as bounding a geographial tract. Fig. 6 shows the region of Fig. 4 divided according to the three foregoing boundary lines.
(5) Fig. 8 shows in ottline the division of the whole atrio of Mt. Aso. Fig. 2 shows in outline the division of the whole district of Mt. Fuji. The same method as used in Fig. 4 to Fig. 7 was used for Figs. 2 and 8.
