River, lake and land conservancy in portions of the provinces of Anhui and Kiangsu, north of the Yangtsze River; . least three years out of five. In 1854 the Yellow River once more went north of Shantung,after 530 years of hard work in the south, but its enormous dyke andraised bed still present an unsurmountable barrier to the free passageof the Huai River to the sea, and the high floods still continue. 17 In 1854, when the Yellow River changed its course once more tothe south, the Tai-ping Rebellion was in full swing, and was layingwaste the Empire south of the Yang-tsze, and in many places to thenorth. The Imperial forces from the north were being hurriedtowards the south to stop the advance of the rebels. There were norailways. To meet the rebels the northern troops must come downthe Grand Canal or march overland. The north dyke of the YellowRiver to the west of Kaifengfu gave way, and the Yellow Riverpoured its torrent of mud and water into this north country from thebreak to the sea. The Grand Canal was thus rendered useless, andfrom the mountains on the west to the sea was a barrier through.

There was much written at that time to prove that eitherthe Taipings or Manchus cut the dyke in order to prevent themoving of troops either north or south, by land or canal. A searchthrough these documents proves nothing either way, but certainlythe dyke gave way, the country was inundated and no troops couldpass, and all at a most opportune time. 18 The Water Supply of the Grand Canal and the OutletsOF THE Hungtze Lake The main water supply of that section of the Grand Canal southof the border of Shantung and north of Thsing Kiang-pu comes fromthe Yi River.
