During the Pacific war the Stock raising of farmer in Japan are declined remarkably. After the war, the heads of horses tend to decrease in number before the war, but on the other hand cattle increase rapidly and have amount to its head number before. These tendencies are the results of the fact that horse-raising farmers have changed into cattle-aising ones, and moreover, many farmers who bad not raised even a head of horse and cattle, have begun to raise cattle. in 1949 the ratio of the number of farm-houses breeding cattle to total farm-houses is 31% and that of breeding horse is is%.
The distribution of the cattle breeding ratio is shown Fig. 4 and Fig. 5 is for the horse. These two distributions are in keen contrast and these aspects suggest that the agricultural management of middle Japan is different from that of the north or south Japan, and that the farm economy of Japan is so Poor that the farmers can not raise two kind of live stock at the same time. The distribution of milk cow is shown in Fig. 6. It is some what interesting that the milk cows are few in the prominent cattle-breeding region and many on the cattle-breeding area within the Prominen horse-breeding region.

Niihama facing the Inland Sea on the north side of Shikoku and having the population of 50, 000, was a poor fishing- and agricultural-village before Meiji-era. The rapid increase of population is due to the development of the Besshi Copper Mine at the back, the smeltering industries including the chemical- and machinery-industries, have been attracted by it successively. This can be recognized as the reason why Niihama has become what it is.

On the Nagase River Delta in northern part of Inawashiro Basin, inhabitants take their drink from irrigation water. Three cases of use of stream for drink are known in our country, -that is, “Kakehi” or other type in mountain regions, artificial water courses in exploited fan or plateau, and drainage ditches in some low delta. The last case shows that irrigation water of rice field can be used for drinking. Such delta is not convenient to get good water by wells, and there is no other way to drink but to scoop the dirty water of drainage ditches. The use of running water on the Nagase River Delta is some-what similar to the last case, but we find in it some highly developed cbaracteristics to be reported here.
The irrigation water of this delta, supplied by Bandai Volcano and artificial waterways “Hanita-zeki” from the Nagase River, is plenty enough and relatively stable throughout the year.
Water Courses of irrigation system lead tne drinKing water to vlllages. But many of them are obviously used in the upper part of the villages only for leading water to the lower field. In other words as they are not concerncd to the minor irrigation systems of their surrounding area, People can get drinking water without affection of rice field (Fig. 6).
In each village an irrigation water course is divided into smaller ditches which lead the water to each house. These ditches form some systematic net-work of water supply, in which the water is supplied at a certain corner of the village, the supply and drainage for each house is carried by a fixed route, and often People effort to avoid the using waste water from another house ( Fig. 1-5 ).
In a house there is a device of getting water, “Idobune”, the drinking water tunk in the kitchen (Shetch). The running water in a ditch is always brought from the upper part of the stream into “Idobune”, and out into the lower Part by te help of a narrow ditch or a under-ground pipe. The device is very convenient especially in snow season.
The characters Written above would be favoured by the the topographic feature of this delta with some relief on it.

The vegetable supplying region for Sendai is divided into four circles by the distance, the variety of vegetable and the season and amount of supply. The first circle is closed by the city and is its oldest vegetable supply region (from “Tokugawa” era), the second circle, which chiefly supplies the vegetable in autumn, was added in “Meiji” era owing to the urban expansion. The third and fourth circles have been formed during the Pacific War, fourth circles suppling the vegetable in spring and the fourth circle being characterized, especially, by the joint shipment of the agricultural community of each viliage.
