RETURN TO JAPAN
We had returned to Japan in the midst of the first rainy season, and all the day through, June 25th, and two nights, a gentle rain fell at Nagasaki, almost without interruption. Across the narrow street from Hotel Japan were two of its guest houses, standing near the front of a wall-faced terrace rising twenty-eight feet above the street and facing the beautiful harbor. They were accessible only by winding stone steps shifting on paved landings to continue the ascent between retaining walls overhung with a wealth of shrubbery clothed in the densest foliage, so green and liquid in the drip of the rain, that one almost felt like walking edgewise amid stairs lest the drip should leave a stain. Over such another series of steps, but longer and more winding, we found our way to the American Consulate where in the beautifully secluded quarters Consul-General Scidmore escaped many annoyances of settling the imagined petty grievances arising between American tourists and the ricksha boys.
Through the kind offices of the Imperial University of Sapporo and of the National Department of Agriculture and Commerce, Professor Tokito met us at Nagasaki, to act as escort through most of the journey in Japan. Our first visit was to the prefectural Agricultural Experiment Station at Nagasaki. There are four others in the four main islands, one to an average area of 4280 square miles, and to each 1,200,000 people. The island of Kyushu, whose latitude is that of middle Mississippi and north Louisiana, has two rice harvests, and gardeners at Nagasaki grow three crops, each year. The gardener and his family work about five tan, or a little less than one and one-quarter acres, realizing an annual return of some $250 per acre. To maintain these earnings fertilizers are applied rated worth $60 per acre, divided between the three crops, the materials used being largely the wastes of the city, animal manure, mud from the drains, fuel ashes and sod, all composted together. If this expenditure for fertilizers appears high it must be remembered that nearly the whole product is sold and that there are three crops each year. Such intense culture requires a heavy return if large yields are maintained. Good agricultural lands were here valued at 300 yen per tan, approximately $600 per acre.
When returning toward Moji to visit the Agricultural Experiment Station of Fukuoka prefecture, the rice along the first portion of the route was standing about eight inches above the water. Large lotus ponds along the way occupied areas not readily drained, and the fringing fields between the rice paddies and the untilled hill lands were bearing squash, maize, beans and Irish potatoes. Many small areas had been set to sweet potatoes on close narrow ridges, the tops of which were thinly strewn with green grass, or sometimes with straw or other litter, for shade and to prevent the soil from washing and baking in the hot sun after rains. At Kitsu we passed near Government salt works, for the manufacture of salt by the evaporation of sea water, this industry in Japan, as in China, being a Government monopoly.
Many bundles of grass and other green herbage were collected along the way, gathered for use in the rice fields. In other cases the green manure had already been spread over the flooded paddies and was being worked beneath the surface, as seen in Fig. 216. At this time the hill lands were clothed in the richest, deepest green but the tree growth was nowhere large except immediately about temples, and was usually in distinct small areas with sharp boundaries occasioned by differences in age. Some tracts had been very recently cut; others were in their second, third or fourth years; while others still carried a growth of perhaps seven to ten years. At one village many bundles of the brush fuel had been gathered from an adjacent area, recently cleared.
A few fields were still bearing their crop of soy beans planted in February between rows of grain, and the green herbage was being worked into the flooded soil, for the crop of rice. Much compost, brought to the fields, was stacked with layers of straw between, laid straight, the alternate courses at right angles, holding the piles in rectangular form with vertical sides, some of which were four to six feet high and the layers of compost about six inches thick.
Just before reaching Tanjiro, a region is passed where orchards of the candleberry tree occupy high leveled areas between rice paddies, after the manner described for the mulberry orchards in Chekiang, China. These trees, when seen from a distance, have quite the appearance of our apple orchards.
At the Fukuoka Experiment Station we learned that the usual depth of plowing for the rice fields is three and a half to four and a half inches, but that deeper plowing gives somewhat larger yields. As an average of five years trials, a depth of seven to eight inches increased the yield from seven to ten per cent over that of the usual depth. In this prefecture grass from the bordering hill lands is applied to the rice fields at rates ranging from 3300 to 16,520 pounds green weight per acre, and, according to analyses given, these amounts would carry to, the fields from 18 to 90 pounds of nitrogen; 12.4 to 63.2 pounds of potassium, and 2.1 to 10.6 pounds of phosphorus per acre.
Where bean cake is used as a fertilizer the applications may be at the rate of 496 pounds per acre, carrying 33.7 pounds of nitrogen, nearly 5 pounds of phosphorus and 7.4 pounds of potassium. The earth composts are chiefly applied to the dry land fields and then only after they are well rotted, the fermentation being carried through at least sixty days, during which the material is turned three times for aeration, the work being done at the home. When used on the rice fields where water is abundant the composts are applied in a less fermented condition.
The best yields of rice in this prefecture are some eighty bushels per acre, and crops of barley may even exceed this, the two crops being grown the same year, the rice following the barley. In most parts of Japan the grain food of the laboring people is about 70 per cent naked barley mixed with 30 per cent of rice, both cooked and used in the same manner. The barley has a lower market value and its use permits a larger share of the rice to be sold as a money crop.
