At Takamatsu I had the opportunity of visiting a daimyo's castle. I was impressed by its strength not only because of the wide moats but because of the series of earthen fortifications faced with cyclopean stonework through which an invading force must wind its way. There was within the walls a surprisingly large drilling ground for troops and also an extensive drug garden. The present owner of the castle proposed to build here a library and a museum for the town. I was glad of the opportunity to ascend one of the high pagoda-like towers so familiar in Japanese paintings. I was disillusioned. Instead of finding myself in beautiful rooms for the enjoyment of marvellous views and sea breezes I had to clamber over the roughest cob-webbed timbers. One storey was connected with another by a stair of rude planking. Such pagodas were built only for their military value as lookouts and for their delightful appearance from the outside. The town now enjoyed as a park of more than ten acres the grounds of a subsidiary residence of the daimyo. The magnificent trees, with lakes, rivulets and hills fashioned with infinite art,[175] and the background of natural hill and woodland, made in all a possession which exhibited the delectable possibilities of Japanese gardening. An occasional electric light amid the trees gave an effect in the evening in which Japanese delight. Some of the old carp which dashed up to the bridges when they heard our footsteps seemed to be not far short of 3 ft. long. Except for a small patch of sugar cane in Shidzuoka--it is grown practically on the sea beach where it is visible from the express--the visitor to Japan may never see sugar cane until Shikoku is reached. The value of the crop in the whole island is about 800,000 yen. The tall cane is conspicuous alongside the more diminutive rice. In this prefecture an experiment is being made in growing olives. Kagawa is remarkable in having had until lately 30,000 pond reservoirs for the irrigation of rice fields. Under the new system of rice-field adjustment many of the ponds are joined together. Because in Shikoku flat tracts of land or tracts that can be made flat are limited in number the farmers have to be content with small pieces of land. The average area of farm in Kagawa outside the mountainous region is less than two acres. When the farms are near the sea, as they commonly are, the agriculturists may also be fishermen.
