The Huai River and the Hungtze I^akeThe Huai River and the Hungtze Lake will be considered as onein the general scheme of conservancy and reclamation. The Huai River rises in the mountains of Honan and dischargesinto the Hungtze Ivake. Its tributaries and catchment basin havebeen described. The two most important tributaries, the Sha andthe Ke have their sources near the Yellow River, the Sha to the westof Khaifeng-fu, the capital of Honan, and the Ke to the east of of these rivers have a navigable depth of about two feet to. A GRAND CANAL LOCK The grooves in which the timber baulks are placed to raise the -waterare here well shown within about thirty miles of Khaifeng-fu. From this point the landis one large marsh, traversed by many small indefinite waters of these rivers, even in extreme floods, carry but littlesilt, and aid but little in continent building. The Huai, itself coming*from the far off mountains of Honan, contains much more silt thanthese rivers, but still very little when compared with the Yang-tszeand the Yellow Rivers. 30 Discharge of the Huai River On the south-west side of HuaiTyuan there are two considerablemountains between which the Huai River passes. To the west ofthis pass is a long stretch of flat country with mountains and highlandsto the south, and very gentl>- rising land to the north. Across thisstretch of some six miles in length the river has a m
