There are many different nominations of mountains in Japan. The author picked up here only the last syllables of the mountain-name. He count, ed More than seventy sorts all in Japan. Among them, “-yama”, “-také”, “-mori”, “-miné”, these four sorts of calling are definitely more frequent than the others. Hence he took in this paper the distribution and meaning oof these four suffixes. This study consists of two parts, the one is title significance and history of these four sorts, and the other is the historical geography of their distribution and meanings. . They are described as follows.
“Yama” is the name that has existed from the ancient time throughout the history of the Yamato race. It distributes widely all over the country and are attached to the highest Mountains as Fujino-yama as well as to the lowest hills as are seen everywher. “-Miné” has long a history as “-yama”, since the earliest time of the Yamato race. Many of these names are found in the famous poetical works, such as Mannyo-shyû. But now “-mine” has become less common because it changed its conceptionn into the meaning of mountain-ridge or tower-shaped peak. It does not distribute so widely as “yama” in the whole country, but is found rather densely is the districts that indicate the past Yamato race's domain and decreases in the marginal areas. “Také” is later in its history of development than “-mine”, but its distribution covers the whole country. It may be remarked that “-také” has a linguistic influence from continent. This development of “-také” was taken in the period of Nara dynasty. Having no distribution within the district of “-miné” and “-sen” (“-sen was existed from ancient times as “-miné”), “-také” has a blank area in the district of “-mine” and “-sen”. (Fig. 4) This district coincides with the area of the earlier period of Yamato dynasty. (Fig. 10) And “-také” is found on the rocky mountain.
“-Mori” has its origin in Ainu and Korean languages, perhaps the former influence was more definite. These names are almost found on the round topped peaks, and its distribution, according to the Law of Baxter, is made up from three districts as no distribution area in the centre, “-mori-yama” region in the intermediary, and “-mori” region in the outer part of Japan.

The writer carried out some investigations on the relation between the amount of soil losses and some physico-chemical properties of soils in Tama. Upland. Soils in his field are classified as follows: Soils in St. 1, St. 2 and St. 3 are Kanto Loam, and those in St. 4 and St. 5 are soils from Pliocene, series.
Conclusions of this paper are as follows:-
(1) Soils derived from Pliocene series-especially St. 4-hav small degree of aggregates, therefore they cause severe runoff and erosion.
(2) Soils from. Pliocene series (St. 4, 5.) have small degree of base saturation, hence they have small degree of aggregates and are unstable to rain wash.
(3) Soils in which humus content is very small (especially St. 4) acarcely cause aggregation, and they have small absorption and permeability of water, so these soils are sucseptible to erosion.
(4) Lower liquid limit of soils derived from Pliocene series (St. 4 and, St. 5) is small (about 40%) and that of Kanto Loam soils is great (about 70%). sothe former soils are unstable to water erosion.
(5) The silica-sesquioxide ratio appears to be the most significant indexof erodibility obtainable by chemical analysis. It is an index of the degree of weathering, and, as a result, of erodibility. That is to say, the soils which have small ratio of silica-sesquioxide are resistible to dispersion and erosion. SiO₂/R₂O₃ of any Kantõ Loam soil is smaller than 2.0, so they resistible to erosion, and those of siols derived from Pliocene series are larger than 2.0, so they are susceptible to erosion.
(6) Generally speaking, physico-chemical properties of Kantõ Loam soils are more resistible to erosion than those derived from Pliocene series.

The fishery flourishes remakably in Ishikawa-ken along its long coast line. Many types of fishery is carried on, although it can by no means be called, a modernized management. We made the regional divisions along the, coast of Ishikawa-ken, using both marine productions and fishing methods, as the basis of division, and four divisions and nine subdivisions were found. They are:-_??_

This is a general report of landutilization in the clearings on the volcano Akagi, and is summarized as follows:- 1. The clearings on the southern slope are mainly cropped to rice and wheat, and, owing to the dry soil and the strong wind, their yields are rather poor, but the settlers, to cope with these disadvantages, have generally no other means than the selection of some suitable varieties of crops and the betterment of the m Method of cultivation. In some clearings, however, where there are many such settlers as were formerly engaged in some other buisinesses then farming, some social activities besides cultivation of commercial crops are being taken into consideration for the establishment of the prosperous settlements.
2. In the clearings on the southwestern slope, the settlers have also to make a choice between selfsupporting and commercial crops, and in this choice, the former crops, owing to the cold climate, are poor, especially in their transportation to markets, and so in either case, the life there is a hard one.
