It was in the steep hills about Tsingtao that we first saw at close range serious soil erosion in China; and the returning of forest growth on hills nearly devoid of soil was here remarkable, in view of the long dry seasons which prevail from November to June, and Fig. 118 shows how destitute of soil the crests of granite hills may become and yet how the coming back of the forest growth may hasten as soon as it is no longer cut away. The rock going into decay, where this view was taken, is an extremely coarse crystalline granite, as may be seen in contrast with the watch, and it is falling into decay at a marvelous rate. Disintegration has penetrated the rock far below the surface and the large crystals are held together with but little more tenacity than prevails in a bed of gravel. Moisture and even roots penetrate it deeply and readily and the crystals fall apart with thrusts of the knife blade, the rock crumbling with the greatest freedom. Roadways have been extensively carved along the sides of the hills with the aid of only pick and shovel. Close examination of the rock shows that layers of sediment exist between the crystal faces, either washed down by percolating rain or formed through decomposition of the crystals in place. The next illustration, Fig. 119, shows how large the growth on such soils may be, and in Fig. 120 the vegetation and forest growth are seen coming back, closely covering just such soil surfaces and rock structure as are indicated in Figs. 118 and 119. These views are taken on the reforestation tract at Tsingtao but most of the growth is volunteer, standing now protected by the German government in their effort to see what may be possible under careful supervision. The loads of pine bough fuel represented in Fig. 80 were gathered from such hills and from such forest growth as are here represented, but on lands more distant from the city. But Tsingtao, with its forty thousand Chinese, and Kiaochow across the bay, with its one hundred and twenty thousand more, and other villages dotting the narrow plains, maintain a very great demand for such growth on the hill lands. The wonder is that forest growth has persisted at all and has contributed so much in the way of fuel.
