After these pits had been filled the clover which was in blossom beyond the pits would be cut and stacked upon them to a height of five to eight feet and this also saturated, layer by layer, with mud brought from the canal, and allowed to ferment twenty to thirty days until the juices set free had been absorbed by the winter compost beneath, helping to carry the ripening of that still further, and until the time had arrived for fitting the ground for the next crop. This organic matter, fermented with the canal mud, would then be distributed by the men over the field, carried a third time on their shoulders, notwithstanding its weight was many tons. This manure had been collected, loaded and carried fifteen miles by water; it had been unloaded upon the bank and saturated with canal mud; the field had been fitted for clover the previous fall and seeded; the pits had been dug in the fields; the winter compost had been carried and placed in the pits; the clover was to be cut, carried by the men on their shoulders, stacked layer by layer and saturated with mud dipped from the canal; the whole would later be distributed over the field and finally the earth removed from the pits would be returned to them, that the service of no ground upon which a crop might grow should be lost. Such are the tasks to which Chinese farmers hold themselves, because they are convinced desired results will follow, because their holdings are so small and their families so large. These practices are so extensive in China and so fundamental in the part they play in the maintenance of high productive power in their soils that we made special effort to follow them through different phases. In Fig. 101 we saw the preparation being made to build one of the clover compost stacks saturated with canal mud. On the left the thin mud had been dipped from the canal; way-farers in the center were crossing the foot-bridge of the country by-way; and beyond rises the conical thatch to shelter the water buffalo when pumping for irrigating the rice crop to be fed with this plant food in preparation. On the right were two large piles of green clover freshly cut and a woman of the family at one of them was spreading it to receive the mud, while the men-folk were coming from the field with more clover on their carrying poles. We came upon this scene just before the dinner hour and after the workers had left another photograph was taken at closer range and from a different side, giving the view seen in Fig. 102. The mud had been removed some days and become too stiff to spread, so water was being brought from the canal in the pails at the right for reducing its consistency to that of a thin porridge, permitting it to more completely smear and saturate the clover. The stack grew, layer by layer, each saturated with the mud, tramped solid with the bare feet, trousers rolled high. Provision had been made here for building four other stacks.
