The rivers in Chehkiang rise in the province; and, as might be inferred from the position of the hills, their course is generally short and the currents rapid. Fourteen principal streams are enumerated, of which the Tsientang is the most important. The main branch of this river rises in the southern districts in two head-waters, which join at Küchau fu and run thence into Hangchau Bay. The bore which comes up into this river fifteen miles, as far as Hangchau, is the only one along the coast. As its wall of water approaches the city, the junks and boats prepare by turning their bows to meet it, and usually rise over its crest, 6 or 10 feet at times, without mishap. The basin of the Tsientang River measures nearly half of the province; by means of rafts and boats the people transport themselves and their produce for about 300 miles to its headwaters. The valley of Lanki is the largest of the bottom lands, 140 miles long and 5 to 15 wide, and passes north through a gorge 70 miles in length into the lower valley, where it receives the Sin-ngan River from the west in Nganhwui, and thus communicates with Hwuichau at times of high water. It is just fitted for the rafting navigation of the region, and by means of its tortuous channels each one of the 29 districts in its entire basin can be reached by water. The forest and fruit trees of Chehkiang comprise almost every valuable species known in the eastern provinces. The larch, elcococcus, camphor, tallow, fir, mulberry, varnish, and others, are common, and prove sources of wealth in their timber and products. The climate is most salubrious; the grains, vegetables, animals, and fishes, furnish food; while its beautiful manufactures of silk are unrivalled in the world, and have found their way to all lands. Hemp, lackered- and bamboo-wares, tea, crockery, paper, ink, and other articles, are also exported. The inhabitants emulate those in the neighboring regions for wealth, learning, and refinements, with the exception of the hilly districts in the south bordering on Kiangsí and Fuhkien. The dwellers of these upland valleys are shut out by position and inclination, so that they form a singularly clannish race. Their dialects are peculiar and very limited in range, and each group of villagers suspects and shuns the others. They are sometimes rather turbulent, and in some parts the cultivation of the mountain lands is interdicted, and a line of military posts extends around them in the three provinces, in order to prevent the people from settling in their limits; though the interdiction does not forbid cutting the timber growing there.[53] ~HANGCHAU AND ITS ENVIRONS.~ Hangchau, the capital of the province, lies in the northern part, less than a mile from the Tsientang. The velocity of this stream indicates a rapid descent of the country towards the ocean, but it discharges very little silt; the tide rises six or seven feet opposite the city, and nearly thirty at the mouth.
