In the Shantung province, in Chihli and in Manchuria, millet stems, especially those of the great kaoliang or sorghum, are extensively used for fuel and for building as well as for screens, fences and matting. At Mukden the kaoliang was selling as fuel at $2.70 to $3.00, Mexican, for a 100-bundle load of stalks, weighing seven catty to the bundle. The yield per acre of kaoliang fuel amounts to 5600 pounds and the stalks are eight to twelve feet long, so that when carried on the backs of mules or horses the animals are nearly hidden by the load. The price paid for plant stem fuel from agricultural crops, in different parts of China and Japan, ranged from $1.30 to $2.85, U. S. currency, per ton. The price of anthracite coal at Nanking was $7.76 per ton. Taking the weight of dry oak wood at 3500 pounds per cord, the plant stem fuel, for equal weight, was selling at $2.28 to $5.00.
Large amounts of wood are converted into charcoal in these countries and sent to market baled in rough matting or in basketwork cases woven from small brush and holding two to two and a half bushels. When such wood is not converted into charcoal it is sawed into one or two-foot lengths, split and marketed tied in bundles, as seen in Fig. 77.
Along the Mukden-Antung railway in Manchuria fuel was also being shipped in four-foot lengths, in the form of cordwood. In Korea cattle were provided with a peculiar saddle for carrying wood in four-foot sticks laid blanket-fashion over the animal, extending far down on their sides. Thus was it brought from the hills to the railway station. This wood, as in Manchuria, was cut from small trees. In Korea, as in most parts of China where we visited, the tree growth over the hills was generally scattering and thin on the ground wherever there was not individual ownership in small holdings. Under and among the scattering pine there were oak in many cases, but these were always small, evidently not more than two or three years standing, and appearing to have been repeatedly cut back. It was in Korea that we saw so many instances of young leafy oak boughs brought to the rice fields and used as green manure.
There was abundant evidence of periodic cutting between Mukden and Antung in Manchuria; between Wiju and Fusan in Korea; and throughout most of our journey in Japan; from Nagasaki to Moji and from Shimonoseki to Yokohama. In all of these countries afforestation takes place quickly and the cuttings on private holdings are made once in ten, twenty or twenty-five years. When the wood is sold to those coming for it the takers pay at the rate of 40 sen per one horse load of forty kan, or 330 pounds, such as is seen in Fig. 87. Director Ono, of the Akashi Experiment station, informed us that such fuel loads in that prefecture, where the wood is cut once in ten years, bring returns amounting to about $40 per acre for the ten-year crop. This land was worth $40 per acre but when they are suitable for orange groves they sell for $600 per acre. Mushroom culture is extensively practiced under the shade of some of these wooded areas, yielding under favorable conditions at the rate of $100 per acre.
