    We retraced on a map several plans formerly allotted, based upon the “Jori” system in Kofu Basin and the results are as follows:
    The remnants of Jori plans still remain chiefly in the patterns of paddy fields along Fuefuki Riverr as well as on the fringes of many fans (Fig. 1. 2). We can distinguish three groups of Jori system from its distribution in this basin. In the first group, the lines N12°E divide each paddy field, while in the second its division is carried out according to N-S & E-W lines, and in the third. the lines incline N 6°E. The first group contain the oldest allotted type and its distribution covers the most extensive areas. We find the second group on the sites of “Kokofu” (the ancient administrative centerr of the province). Its allotment seems to be based upon the “Jobo” (ancient city planning) and was carried out after Taika Revolution (646 A. D.). The third group still remains in Koma-gun, and the distribution of latter two groupes is ratherr restricted. There are two types of land division 6×60 ken and 12×30 ken (nearly 12a.), of which the former type is older. than the latter.

    There are six “honden” or old villages founded before middle age, around the elevated delta of Hokura Riverr in Niigata Prefecture. In this paper the writerr is going to describe the Honden of Katatsu, as reports on the other five villages have been written in his other papers. Katatsu is an old village along a formerr lagoon, and at the beginning of modern age (1593) consisted of eight houses and 12 chobu of fields. The seats of rice fields of this village in those days seems to have been selected at the bottom of small valleys dissecting elevated delta. These valleys are about 50m. wide and 2-3m. deep. The surface of elevated delta in those days had no resources of irrigation water, while the valley bottoms could take advantage of rain and underground water, howeverr not abundant, hence the development of rice, fields. Like other five honden villages it used natural water for irrigation, and characteristics are seen in the way of land divisions etc.
    The surface of elevated delta was coloninzed in the early part of modern age, when long canals of irrigation were led into this region and many “Shinden” or newly colonized villages were established.

    The present paper deals especially with the cropping systems in upland fields where tobacco is not cultivated; the characteristics of which run as follows:
    (A) Summer Crops. (1) In each section the repetition of same crops is avoided as a rule, although crop-alternation are generally irreguler. (2) Though the kind of summer crops are same in each section, the dominant crops in acreage, which appear most frequently in the present cropping systems, are upland rice and barnyard millet in the upland field section α, and upland rice in β. No predominance would take place by such crop as upland rice or barnyard millet in the paddy field section.
    (B) Winter Crops. (1) In every section wheat acreage reaches approximately as much as two times that of barley, often resulting with the repetition. of the former, in the present systems. (2) Regarding the ratio between barley and wheat appearing in the systems, every section has a different value The contrast of the ratio is most striking between the paddy field section and that of upland field as a whole. This areal difference arises from the, characteristic combination of rice and tobacco with barley as preceding crop, because of the reason worked out in the foregoing paper. Although wheat plays dominant part as winterr crop throughout both the upland field and paddy field sections, barley replaces it rather frequently in the former. Concerning the latter section on the other hand, wheat is nearly an exclusive winter crop cultivated in. the present systems.
    The following are examples, where a, b and c signifie the upland field. sections α, β and paddy field section respectively.

    At the eastern foot of Kanto-Mountainland, there are two hills of Kusabana and Kaji near Ome, which are composed of the gravel beds more than 100m thick. As shown in, Fig. 3, in the west, these gravel beds are laterally in contact with hard Chichibu System (Palaeozoic), which occupies the widest area in Kanto-Mountainland, and vertically overlie unconforrably Busi Bed (uppermost Tertiary), which distributes into Kanto Basin together with cont-emporaneous formations.
    Judging from the sorts of gravels and the existence of obsequent tributary of Tama River (Fig. 1), the gravel beds are regarded as the deposits of Old Tame River, and from their distributions and their surface features, they are regarded as fanglomerates.
    From the facts above outlined, it is inferred that Busi Bed suffered more deepening of the extended rivers that had occurred in succession to the regression of sea, than Chichibu System, so that the knickpoints were formed near the boundary between them, hence the fanglomerates deposited in the vicinity of the knickpoints.
