    1. In a previous paper, the writer discussed statistically the emigration regions in SHIKOKU and determined the factors causing emigration from each regions. The geographical factors in any region should not be consi-dered individually, but as a whole; from the geographical point of view, they must be attributed to the structure of the regions be thought of in combination.
    The writer, as in the SHIKOKTJ, study listed (1) the ratio of farm, (2) that of subsidiary farmers and (3) that of small farmers as facors of emigration And tried to determine relationshipt between the factors.
    2. In this paper KANTO cosznprises, six prefectures of the KANTO District and four prefectures in SOUTHERN CHUBU, (Shizuoka, Aichi, Mie and Wakayama). The latter two generally belong to the KINKI District, but are included because of their similarity to the other two io several aspects.
    3. At first, simple correlation coefficients between the ratio of the emi-grants to all farmers and to each of the three factors were calculated. The correlation of the farm is very low, therefore it cannot be considered as a cause of emigration. In regard to Vie otter two, their correlations are all lineal (Table 1.) and the test by correlation covariance demonstrates that -the regression coefficients bi in the equation Y=b0+biXi are all significant.
    4. The multiple correlation coefficients between Y and X1, X2 and the multiple regression equation were determined as follows: ry.X1X2=0.62 in KANTO ry.XlX=0.74 in CHUBU _??_ The estimated values of the emigrants by the eq uation almost coincide with their actual values (Fig. 1, 2, 3, 4.), therefore, by the test of the partialre gression coefficients, the causes of emigration can be determined in each region.

    (1) 離村者は入村者よりは多く,自町村内移動は最も少ない. (2) 女子が主體である. (3) 自村村内移動は廣い町村や西部の山間村に多い傾向がある. (4) 縣内移動は縣外移動よりも著しく多い上に,離村が入村よりも多く,出婚圏と入婚圏とは類似するが前者は東部に,後者は西部に廣く,通婚圏は近距離地域で,各形とは關係なく西部に廣い. (5) 縣外移動が入村より著しく多いが,通婚圏は近距離地域と都市地域とで,本籍移動者を除けば,近くは出婚圏としての,遠くは入婚圏としての色彩が強く,移動方向は北や北東で,殊に北へがその逆流よりは著しく強い. (6) 人口比率からは自町村内,縣内,縣外の順に多い, (7) 男子は近距離移動が多い. (8) 移動年令は22才をピークとして巾が廣いが,男子はピークが少しおくれ且年令別變化が少なく,町村別では西部に若い傾向がある. (9) 移動年も巾が廣いが1年前のものがピークで5年前のものは少なく,男子や離婚者や小さい町村は届出が早く古いものは少ない.移動月は3つのピークと3つの谷とをもつて冬から春に多く,夏から秋に少ないが,離婚のみでは,又町村別では餘り變化がない.
    本研究は1952年度文部省科學研究費による四國山間村の縁組による人口移動の研究の一部であることを特記し謹しんで謝意を表する次第である.

    The bicycle plays as important a role as a means of communication in Japan as the motor-car does in the United States. The author investigated bicycle traffic in the Kujûkuri Plain of Chiba Prefecture in 1952 and arrived at the following conclusions:
    (1) The ratio of bicycles to the population of a town or village is propo-rtionate to the community's distance from the nearest railway station. (Fig. 1)
    (2) The sphere of influence of railway stations from which people com-mute to their offices by bicycles are shown in Fig. 2; their radii are found to be about 10 kilometers.
    (3) A map of distribution of residences of the students of Chosei High School in Mobara City is shown, in Fig. 3. From this map the limit of attendance by bicycle can be determined; the largest radius is 12 kilometers.
    (4) Market areas of fresh fish pedlers utilizing bicycles and starting from fishing villages along the Kujukuri beach are shown in Fig. 4. The maximum radius is 30 kilometers; the average radius is 20 kilometers.
    (5) In Fig. 6 the four (C, D, E1 and E2) bicycle traffic circles are, centered on AIobara City. The 6 circles obtained by adding two other circles (see Tab. 1) to the above four may be termed the circular structure of bicycle traffic of Mobara City.

    The writers carried out certain investigations in order to estimate the amount of groundwater discharge through the Watarase River valley near Kiriu City in Gumma Prefecture.
    They surveyed the geology of the flood plain by means of electric resisti-vity methods using apparatus of the Electro-Technical Laboratory type and check the results by test borings (Fig. 1).
    The Watarase River valley is underlain by Tertiary formations and dilu-vial and alluvial deposits. The alluvial deposit, with a maximum depth of 20 meters. is divided into an upper and a lower layer. The upper layer, composed of loose sand and gravel, is the most productive aquifer; the -diluvial deposit has some confining aquifers.
    From the groundwater contour map (Fig. 1), obtained from observation of 30 wells, it was found that groundwater generally furnishes the river water throughout the valley, but locally influent seepages occur in some places.
    The writers calculated the gradient of the groundwater flow and evaluated -the permeability coefficient by Tienis' method as modified by Muskat.
    Using the data arrived at by the above methods, they calculated the amount of groundwater discharge through a valley section at 1.253m)sec.
