The plants for this crop are started in nursery beds in February and transplanted in May, the first crop being cut the last of June or first of July, when the fields are again fertilized, the stubble throwing out new shoots and yielding a second cutting the last of August or early September. A crop of barley may have preceded one of indigo, or the indigo may be set following a crop of rice. Such practice, with the high fertilization for every crop, goes a long way toward supplying the necessary food. The dense population, too, has permitted the manufacture of the indigo as a home industry among the farmers, enabling them to exchange the spare labor of the family for cash. The manufactured product from the reduced planting in 1907 was worth $1,304,610, forty-five per cent of which was the output of the rural population of the prefecture of Tokushima, which they could exchange for rice and other necessaries. The land in rice in this prefecture in 1907 was 73,816 acres, yielding 114,380,000 pounds, or more than 161 pounds to each man, woman and child, and there were 65,665 acres bearing other crops. Besides this there are 874,208 acres of mountain and hill land in the prefecture which supply fuel, fuel ashes and green manure for fertilizer; run-off water for irrigation; lumber and remunerative employment for service not needed in the fields.
The journey was continued from Kyoto July 7th, taking the route leading northeastward, skirting lake Biwa which we came upon suddenly on emerging from a tunnel as the train left Otani. At many places we passed waterwheels such as that seen in Fig. 241, all similarly set, busily turning, and usually twelve to sixteen feet in diameter but oftenest only as many inches thick. Until we had reached Lake Biwa the valleys were narrow with only small areas in rice. Tea plantations were common on the higher cultivated slopes, and gardens on the terraced hillsides growing vegetables of many kinds were common, often with the ground heavily mulched with straw, while the wooded or grass-covered slopes still further up showed the usual systematic periodic cutting. After passing the west end of the lake, rice fields were nearly continuous and extensive. Before reaching Hachiman we crossed a stream leading into the lake but confined between levees more than twelve feet high, and we had already passed beneath two raised viaducts after leaving Kusatsu. Other crops were being grown side by side with the rice on similar lands and apparently in rotation with it, but on sharp, narrow close ridges twelve to fourteen inches high. As we passed eastward we entered one of the important mulberry districts where the fields are graded to two levels, the higher occupied with mulberry or other crops not requiring irrigation, while the lower was devoted to rice or crops grown in rotation with it.
On the Kisogawa, at the station of the same name, there were four anchored floating water-power mills propelled by two pair of large current wheels stationed fore and aft, each pair working on a common axle from opposite sides of the mill, driven by the force of the current flowing by.
