This is widely practised in China in compliance with the national policy of an all-round development of a diversified economy (see also section ). It is interesting to note, as mentioned to the Mission, that 50 kg of fish produce enough pond humus to fertilize 6 m 2 (10 mu) of crop land. This is the practical reason for locating the.

The biology of the indigenous freshwater snails, Pila luzonica and Vivipara angularis, and the freshwater clam, Corbicula manillensis have been described in the literature. The recovered land itself looks like a series of islands ; about every quarter of a mile is a fresh-water canal, in which are dozens of chain-pumps, worked by treadles, buffaloes, and hand, for the purpose of irrigation; so valuable is land about here for this cause, and by reason of the facilities of transport, that it lets, merely' for the.
