Section along the Yangtse Kiang from the Pacific Coast to Pingshan (hien) in Western Sz'chuen.
The portion of the section lying between the coast and the coal-field of Kwei is based on the
observations of the author; the remainder is deduced from the observations of Capt. Blackiston, and from the study of the mineral productions of the province of Sz'chuen.
The horizontal distances are taken from the Admiralty charts of the river between the coast and the
Tungting lake; thence to Pingshan (hien), from Blackiston's chart of the Upper Yangtse.
The vertical distances east of the Tungting lake are from the Admiralty surveys; west of the
Tungting lake they are merely estimated.
