The Nan shan runs along the north, between it and Kiangsí and Hunan, in a northeasterly and southwesterly direction, presenting the same succession of short ridges, with bottom lands and clear streams between them, which are seen in Fuhkien. These ridges take scores of names as they follow one another from Kwangsí to Fuhkien, but no part is so well known as the road, twenty-four miles in length, which crosses the Mei ling (_i.e._ Plum ridge), between Nan-ngan and Nanhiung. The elevation here is about a thousand feet, none of the peaks in this part exceeding two thousand, but rising higher to the west. Their summits are limestone, with granite underlying; granite is also the prevailing rock along the coast. Lí-mu ridge in Hainan has some peaks reaching nearly to the snow-line. The bottoms of the rivers are wide, and their fertility amply repays the husbandman. Fruits, rice, silk, sugar, tobacco, and vegetables, constitute the greater part of the productions. Lead, iron, and coal, are abundant.
The Chu kiang, or Pearl River, which flows past Canton, takes this name only in that short portion of its course; it is however preferable to employ this as a distinctive name, comprehending the whole stream, rather than to confuse the reader by naming the numerous branches. It is formed by the union of three rivers, the West, North, and East, the two first of which unite at Sanshwui, west of the city, while the East River joins them at Whampoa. The Sí kiang, or West River, by far the largest, rises in the eastern part of Yunnan, and receives tributaries throughout the whole of Kwangsí, along the southern acclivities of the Nan shan, and after a course of 500 miles, passes out to sea through numerous mouths, the best known of which is the Bocca Tigris. The Peh kiang, or North River, joins it after a course of 200 miles, and the East River is nearly the same length; these two streams discharge the surplus waters of all the northern parts of Kwangtung. The country drained by the three cannot be much less than 150,000 square miles, and most of their channels are navigable for boats to all the large towns in this and the province of Kwangsí. The Han kiang is the only river of importance in the eastern end of Kwangtung; the large town of Chauchau lies near its mouth. There can hardly be less than three hundred islands scattered along the deeply indented coast line of this province between Namoh Island and Annam, of which nearly one-third belong to the department of Kwangchau.
