Tlle Chowhsien-Hofie Canal has been long ruined. It formerly connected the Yangtze and the Hl1a1110, and in certain periods, outdid the Elall-Gou Canal. The present paper deals only with its former course and navigation. Tlle Shih-shui and the Fei-shui ale originated in the same source ilea, but the Shih flows south eastward to the Lake Chow--lm, while tile Fei northward to the Huai. The constlvction of the canal took tile advantage of the closeness of the two rivers in their souzce area. According to Shiu-Cbiug-Chu, the two levels were connected, besides near the source, 11 (itller two navigable stretc}les; One connected the Fei and one of the northern branches of the Sliih which, then, turned to the west; the other con-nection was by way of Lake Yang-hu a,nd Heng Tang. It remains a question as to when, and by whom the egcavat.ion through the Huai-Yang hills was made, although evidences are for the people of the ancient Chu State. The Canal was closely belated to the regulation resel}}oir Sho-po. Tlle reservoir was large enough to receive the Pei and the Fei and there were 5locks to adjust the level of the Fei. It was them an inseparable part of the canal. Tlle late con-servancy work was concentrated to ilTigation v}itllout adeduate attention to the navigation of the Chowhsien-lIofei Canal. In the Shui Dynasty, the Han-Gou Canal was dhedged and in some way replaced the Chow hsien-Hofei Canal. The latter was further neglected by the gradually diminishing in volume of the reservoir Sho-Bo.
