The total length of this system as outlined above is about 6,700 miles. In addition there will be two connecting lines between Chengtu and Chungking; another from east of Tsunyi on line (b) southward to Wengan on line (c); another from Pingyueh on line (c) to Tuyun on line (d); another from the border of Kweichow on line (d) through Nantan and Noti to Tunglan on line (e), thence through Szecheng to Poseh on line (f). These connecting lines total about 600 miles. So the grand total will be about 7,300 miles. This system will be intersected by three lines. First, the existing French line from Laokay to Yunnanfu with a projected line from Yunnanfu to Chungking crosses line (f) at Amichow, line (e) at Weining, line (d) at Suifu, line (c) at Luchow, and meets lines (a) and (b) at Chungking. Second, the projected British line from Shasi to Sinyi crosses line (a) at Shenchow, line (b) at Chenyuen, line (c) at Pingyueh, line (d) at Kweiyang and a branch of line (e) at a point west of Yungning. Third, the projected American line from Chuchow to Yamchow crosses line (a) at Yungchow, line (b) at Chuanchow, line (c) at Kweilin, line (d) at Liuchow, line (e) at Tsienkiang, line (f) at Nanning, and meets line (g) at Yamchow. Thus, if this system and the three projected French, British, and American lines are completed, Southwestern China would be well provided with railway communications. All these lines will run through the length and breadth of a vast mineral country, in which most of the essential and valuable metals of the world are found. There is no place in the world which possesses as here so many varieties of rare metals, such as wolfram, tin, antimony, silver, gold, and platinum and at the same time so richly provided with the common but essential metals, such as copper, lead, and iron. Furthermore, almost every district in this region is abundantly provided with coal, so much so that there is a common saying: "Mu mei pu lih cheng," that is, "Nobody would build a city where there is no coal underneath." The idea was that in case of a siege those within the city might obtain fuel from under the ground. In Szechwan, petroleum and natural gas are also found in abundance. Thus, we see that this Southwestern Railway System for the development of mineral resources in the mountainous regions of Southwestern China is just as important as the Northwestern Railway System is for the development of agricultural resources in the vast prairies of Mongolia and Turkestan. These railway systems are a necessity to the Chinese people and a very profitable undertaking to foreign capitalists. They are of about equal length, viz.--about 7,000 miles. The cost per mile of the Southwestern System will be at least twice that of the Northwestern System, but the remuneration from the development of mineral resources will be many times that from the development of agricultural resources.
