i. The Sian-Chungking Line

This line starts from Sian almost directly southward, crosses the Tsingling Mountain into the Han Valley, passes through Ningshen, Shihchuan, and Tzeyang, ascends the Jenho Valley across the southern border of Shensi into the province of Szechwan at Tachuho. Then crossing the watershed of the Tapashan into the Tapingho Valley, it follows that valley down to Suiting and Chuhsien. Thence it turns to the left side of the valley to Linshui and follows the trade road to Kiangpeh and Chungking. The entire distance of this line is about 450 miles through a very productive region and rich timber land.

j. The Lanchow-Chungking Line

This line starts from Lanchow southwestward and follows the same route as line (a) as far as Titao. Thence, it branches off and ascends the Taoho Valley across the Minshan watershed into the Heishui Valley following it down to Kiaichow and Pikow. After Pikow, it crosses the Kansu border into Szechwan and proceeds to Chaohwa, where the Heishuiho joins the Kialing. From Chaohwa, it follows the course of the Kialing River down to Paoning, Shunking, Hochow, and Chungking. The line is about 600 miles long, running through a very productive and rich mineral land.

k. The Ansichow-Iden line

This line passes through the fertile belt of land between the Gobi Desert and the Altyntagh Mountain. Although this strip of land is well watered by numerous mountain streams yet it is very sparsely populated, owing to the lack of means of communication. When this line is completed, this strip of land will be most valuable to Chinese colonists. The line starts from Ansichow westward to Tunhwang, and skirts the southern edge of the Lobnor Swamp to Chochiang. From Chochiang, it proceeds in the same direction via Cherchen to Iden where it connects with the terminus of the Northwestern System. With this System, it forms a continuous and direct line from the Great Eastern Port to Kashgar at the extreme west end of China. This line from Ansichow to Iden is about 800 miles in length.
