The Northwestern Railway System covers the region of Mongolia, Sinkiang, and a part of Kansu, an area of 1,700,000 square miles. This territory exceeds the area of the Argentine Republic by 600,000 square miles. Argentina is now the greatest source of the world's meat supply, while the Mongolian pasture is not yet developed, owing to the lack of transportation facilities. As Argentina has superseded the United States in supplying the world with meat, so the Mongolian pasture will some day take the place of Argentina, when railways are developed and cattle raising is scientifically improved. Thus the construction of railroads in this vast food-producing region is an urgent necessity as a means of relieving the world from food shortage. In the first program of this International Development Scheme, I proposed 7,000 miles of railways for this vast and fertile region, for the purpose of developing the Great Northern Port, and relieving the congested population of southeastern China. But this 7,000 miles of railways form merely a pioneer line. In order to develop this virgin continent properly, more railways have to be constructed. Therefore in this plan, namely, the Extension of the Northwestern Railway System, I propose the following lines: a. The Dolon Nor-Kiakata line. b. The Kalgan-Urga-Tannu Ola line. c. The Suiyuan-Uliassutai-Kobdo line. d. The Tsingpien-Tannu Ola line. e. The Suchow-Kobdo line. f. The Northwestern Frontier line. g. The Tihwa or Urumochi-Ulankom line. h. The Gaskhiun-Tannu Ola line. i. The Uliassutai-Kiakata line. j. The Chensi or Barkul-Urga line. k. The Suchow-Urga line. l. The Desert Junction-Kerulen line. m. The Khobor-Kerulen-Chikatobo line. n. The Wuyuan-Taonan line. o. The Wuyuan-Dolon Nor line. p. The Yenki-Ili line. q. The Ili-Hotien line. r. The Chensi-Kashgar line and its branches. a. The Dolon Nor-Kiakata Line This line starts from Dolon Nor and proceeds in a northwesterly direction, following the caravan road across the vast pasture to Khorkho, Kuoto, and Suliehto. After Suliehto, it crosses the boundary line into Outer Mongolia by the same road to Khoshentun, Lukuchelu, and Yangto. Thence it crosses the Kerulen River to Otukunkholato, and enters the hilly region where it crosses the Kerulen watershed and the Chikoi watershed. The water from the Kerulen watershed flows into the Amur, and thence into the Pacific Ocean, while the water from the Chikoi watershed flows into Lake Baikal, and thence to the Arctic Ocean. After crossing the Chikoi watershed, it follows a branch of the Chikoi River to Kiakata. This line covers a distance of about 800 miles. b. The Kalgan-Urga-Tannu Ola Line
