ジャーナル フリーThe Southern Kyushu here described is that part between the Yatsushiro-Usuki fault line and the volcanic groups of Mt. Kirishima. The highest point is the top of Mt. Kunimidake 1793m in the central part of this region. Next is Mt. Ichibusa of 1722m. The names Baru or Bara common in this region refer to surfaces with low relief in the mountains. These are ‘Piedmontfläche’.
1) Horizontal distribution. Figs. 1-7 show the horizontal distribution of ‘piedmontfläche’ along the upper course of the rivers Kuma and Mimi. The remnants of the central parts of the mountains form ridges that are not well preserved. But the remnants of the marginal parts are better preserved than the preceding, retaining on the whole their roundforms. At present, the remnants of the ‘Piedmontfläche’ are being destroyed by the violent erosional process of the swift Kuma and Mimi rivers. The horizontal distribution of the remnants is generally symmetrical to the river courses.
2) Vertical distribution. Regarding the altitude of each remnant on the ‘Piedmontfläche’, there are several groups of remnants to be considered. Figs. 8-9 show the profiles along the ridges of the mountains. There are six groups of such surfaces, namely. 1480m, 1279m, 1200m, 1120m, 960m, 750m.
The uppermost parts of them are very flat surfaces, but the lower parts have some inclination. The former is probably Endrumpffläche and the latter ‘Primärerumpf’. These six groups form the ‘Piedmonttreppe’.抄録全体を表示PDF形式でダウンロード (2371K) -

ジャーナル フリーThe author, in connection with certain chorological investigations of the Tama-hill, had the opportunity of collecting data in regard to the frequency-distribution of the degree of surface inclination as well as certain cultural phenomena. In this paper he gives a short review of the superficial relation between the degree of the surface inclination and the cultural phenomena of this district and compares it with the same relation that obtains in the Yurugi-hill. In order to study these relationships from topographical maps, the present author adopted the so-called statistical mesh, a new method recently introduced in geography by Dr. T. Terada, and adopted by Mr. S: Yoshimura, especially in chorological interpretations. Some of the most interesting results obtained by this method in connection with the above-mentioned hills are as follows.
1) While the average inclination of the Yurugi-hill is steeper than that of the Tama-hill, conversely the extent of cultivation in the former is somewhat greater than in that of the latter.
2), The slope of the Yurugi-hill is cultivated more intensively than that of the Tama-hill.
3) The areal developement of paddy fields in the Tama-hill is greater than that of the Yurugi-hill.抄録全体を表示PDF形式でダウンロード (1115K) -

ジャーナル フリーThe districts in Japan where the cultivation of the cherry fruit may be carried on as an industry is limited, for the condition of the land surrounding the orchard have no little effect upon the result of the harvest. The places suitable for the cultivation of this fruit in Japan lie chiefly in the northern parts of the country, especially in basing in the Yamagata, Yonezawa, and Fukusima districts., In these places the amount of rainfall in April, the season of the cherry blossoms, is under 100cm. It is under 150cm in the season of the harvest, which begins from the last io days of July, when. the air is comparatively dry and the ground is exposed to the strong direct rays of the sun with the thermometer standing about 12°C.
The cherry tree thrives best in a soil that drains well, such as that of fans and consisting largely of sand and pebbles. Possibly all the fruits are now.produced, in the fan districts. It seems that the earlier the season of harvest the better the chances of successful cultivation. With improved methods of cultivation, the area of production is steadily increasing and extending to places that were once concidered unpromising, such as the Yamanasi fan. With the advent of the refrigerator car, the fruit from North-Eastern Japan will soon be obtainable throughout the Empire.抄録全体を表示PDF形式でダウンロード (2064K) -

ジャーナル フリーMany types of allottment are to be found on cadastral maps. From the cadastral maps of Tokyo and Yokohama the author has classified and described them as in the under-mentioned lists. (Excluding planned cities)
_??_
He next found a method of distinguishing a new road from an old one. The method starts from the principle that an old road harmonises with the forms of allottment, but not so with a new road. By this method he distinguished the older Tôkaidô main road from later ones. He also found the oldest Tôkaidô road that passed through Ômori before the Edo era.抄録全体を表示PDF形式でダウンロード (2676K) -
