Note 71 — Chapter XXXVI
Reading edition
Dr. Smith makes particular mention of coal as being commonly seen in China during Lord Macartney's embassy. Pits of coal were found near the Poyang lake above Nankin. He says that the coal found in the province of Pechelee was a species of graphite; that which was seen near the Yangtze river was like Kennel coal, and that observed near the Poyang lake resembled covey coal. Other coal found at Chow-chow-foo contained much sulphur, and was used in the manufacture of sulphate of iron in the neighbourhood of that city.
