In connection with their farm duties these Japanese families manufactured, from a portion of their rice straw, at night and during the leisure hours of winter, 8,980,000 pieces of matting and netting of different kinds having a market value of $262,000; 4,838,000 bags worth $185,000; 8,742,000 slippers worth $34,000; 6,254,000 sandals worth $30,000; and miscellaneous articles worth $64,000. This is a gross earning of more than $21,000,000 from eleven and a half townships of farm land and the labor of the farmers' families, an average earning of, $80 per acre on nearly three-fourths of the farm land of this prefecture. At this rate three of the four forties of our 160-acre farms should bring a gross annual income of $9,600 and the fourth forty should pay the expenses.
At the Nara Experiment Station we were informed that the money value of a good crop of rice in that prefecture should be placed at ninety dollars per acre for the grain and eight dollars for the unmanufactured straw; thirty-six dollars per acre for the crop of naked barley and two dollars per acre for the straw. The farmers here practice a rotation of rice and barley covering four or five years, followed by a summer crop of melons, worth $320 per acre and some other vegetable instead of the rice on the fifth or sixth year, worth eighty yen per tan, or $160 per acre. To secure green manure for fertilizing, soy beans are planted each year in the space between the rows of barley, the barley being planted in November. One week after the barley is harvested the soy beans, which produce a yield of 160 kan per tan, or 5290 pounds per acre, are turned under and the ground fitted for rice, At these rates the Nara farmers are producing on four-fifths or five-sixths of their rice lands a gross earning of $136 per acre annually, and on the other fifth or sixth, an earning of $480 per acre, not counting the annual crop of soy beans used in maintaining the nitrogen and organic matter in their soils, and not counting their earnings from home manufactures. Can the farmers of our south Atlantic and Gulf Coast states, which are in the same latitude, sometime attain to this standard? We see no reason why they should not, but only with the best of irrigation, fertilization and proper rotation, with multiple cropping.

SILK CULTURE
Another of the great and in some ways one of the most remarkable industries of the Orient is that of silk production, and its manufacture into the most exquisite and beautiful fabrics in the world. Remarkable for its magnitude; for having had its birthplace apparently in oldest China, at least 2600 years B. C.; for having been founded on the domestication of a wild insect of the woods; and for having lived through more than four thousand years, expanding until a $1,000,000 cargo of the product has been laid down on our western coast at one time and rushed by special fast express to New York City for the Christmas trade.
Japan produced in 1907 26,072,000 pounds of raw silk from 17,154,000 bushels of cocoons, feeding the silkworms from mulberry leaves grown on 957,560 acres. At the export selling price of this silk in Japan the crop represents a money value of $124,000,000, or more than two dollars per capita for the entire population of the Empire; and engaged in the care of the silkworms, as seen in Figs. 184, 185, 186 and 187, there were, in 1906, 1,407,766 families or some 7,000,000 people.
Richard's geography of the Chinese Empire places the total export of raw silk to all countries, from China, in 1905, at 30,413,200 pounds, and this, at the Japanese export price, represents a value of $145,000,000. Richard also states that the value of the annual Chinese export of silk to France amounts to 10,000,000 pounds sterling and that this is but twelve per cent of the total, from which it appears that her total export alone reaches a value near $400,000,000.
The use of silk in wearing apparel is more general among the Chinese than among the Japanese, and with China's eightfold greater population, the home consumption of silk must be large indeed and her annual production must much exceed that of Japan. Hosie places the output of raw silk in Szechwan at 5,439,500 pounds, which is nearly a quarter of the total output of Japan, and silk is extensively grown in eight other provinces, which together have an area nearly fivefold that of Japan. It would appear, therefore, that a low estimate of China's annual production of raw silk must be some 120,000,000 pounds, and this, with the output of Japan and Korea, would make a product for the three countries probably exceeding 150,000,000 pounds annually, representing a total value of perhaps $700,000,000; quite equalling in value the wheat crop of the United States, but produced on less than one-eighth of the area.
According to the observations of Count Dandola, the worms which contribute to this vast earning are so small that some 700,000 of them weigh at hatching only one pound, but they grow very rapidly, shed their skins four times, weighing 15 pounds at the time of the first moult, 94 pounds at the second, 400 pounds at the third, 1628 pounds at the fourth moulting and when mature have come to weigh nearly five tons—9500 pounds. But in making this growth during about thirty-six days, according to Paton, the 700,000 worms have eaten 105 pounds by the time of the first moult; 315 pounds by the second; 1050 pounds by the third; 3150 pounds by the fourth, and in the final period, before spinning, 19,215 pounds, thus consuming in all nearly twelve tons of mulberry leaves in producing nearly five tons of live weight, or at the rate of two and a half pounds of green leaf to one pound of growth.
According to Paton, the cocoons from the 700,000 worms would weigh between 1400 and 2100 pounds and these, according to the observations of Hosie in the province of Szechwan, would yield about one-twelfth their weight of raw silk. On this basis the one pound of worms hatched from the eggs would yield between 116 and 175 pounds of raw silk, worth, at the Japanese export price for 1907, between $550 and $832, and 164 pounds of green mulberry leaves would be required to produce a pound of silk.
