m. The Khobor-Kerulen-Chikatobo Line

This line starts from Khobor, the crossing junction of the Dolon Nor-Urumochi, and the Kalgan-Urga-Tannu Ola lines, and proceeds northeastward across a vast pasture to Khoshentun, where it crosses the Dolon Nor-Kiakata line. After Khoshentun, it proceeds in the same direction across a similar pasture to Kerulen, where it crosses the Dolon Nor-Kerulen line. Then it proceeds first along the right bank of the Kerulen River, then crosses to the left side, and passes along the northwestern side of Hulan Lake. After Hulan Lake, the line crosses the Chinese Eastern Railway, and the Arguna River, then proceeds along the right bank of the river to Chikatobo, where the line ends by joining the Dolon Nor-Moho and the Chikatobo-Sansing lines. This line covers a distance of about 600 miles. The first half of it runs on dry land and the second half on watered land.

n. The Wuyuan-Taonan Line

This line starts from Wuyuan at the northwest bend of the Hoangho and proceeds northeastward across the Sheiten Ula Mountain and pasture to Tolibulyk, where it meets the crossing junction of three lines--the Peking-Hami line, the Suiyuan-Kobdo line, and the Great Eastern Port-Urga line. From Tolibulyk the line proceeds continuously in the same direction across a pasture to Khobor where it meets the crossing junction of the Dolon Nor-Urumochi and the Peking-Urga lines, and also the terminus of the Khobor-Kerulen line. After Khobor the line turns more eastward and runs across the Dolon Nor-Kiakata line midway to Khombukure, where it crosses the Dolon Nor-Kerulen and the Hulutao-Kerulen lines. From Khombukure the line proceeds to Dakmusuma, where it crosses the Dolon Nor-Moho line. Thence it goes eastward across the Great Khingan Mountain to Tuchuan, then turns southeastward to Taonan, where it ends. This line covers a distance of about 900 miles.

o. The Wuyuan-Dolon Nor Line

This line starts from Wuyuan and proceeds northeastward across the Sheiten Ula Mountain to Maomingan, where it crosses the Great Eastern Port-Urga line. Then it proceeds across the vast pasture and the Suiyuan-Kobdo line to Bombotu, where it passes over the Peking-Hami line. After Bombotu, the line turns eastward and proceeds across the Kalgan-Urga-Tannu Ola line, then goes to Dolon Nor, where it ends by joining the Dolon Nor-Mukden-Linkiang line, which forms a direct route from the upper Hoangho Valley to the rich Liaoho Valley. This line covers a distance of about 500 miles.

p. The Yenki-Ili Line

This line starts from Yenki or Karashar, and proceeds northwestward across the mountain pass into the Ili Valley. It then follows the Kunges River downward, in a westerly direction, traversing a most fertile valley, to Ining and Kuldja or Ili, the principal city of the Ili district near the Russian border, where it joins the Ili-Urumochi line. This line covers a distance of about 400 miles.

q. The Ili-Hotien Line

This line starts from Ili or Kuldja, proceeds southward across the Ili River, then eastward along the left side of the river and then southeastward and southward to Bordai. From here it turns southwestward into Tekes Valley and proceeding upward crosses the Tekes River to Tienchiao and then ascends the mountain pass. After the mountain pass the line turns southeastward, traverses a vast coal field and then turns southwestward to Shamudai, where it crosses the Turfan-Kashgar line. From Shamudai it turns southward across the fertile zone of the north side of the Tarim Valley, to Bastutakelak. Then it proceeds southwestward to Hotien passing by on the way many small settlements in the fertile zone of the Hotien River which flows across the desert. At Hotien the line meets the Kashgar-Iden line. After Hotien the line proceeds upward to the highland south of the city and ends at the frontier. This line covers a distance of about 700 miles.

r. The Chensi-Kashgar Line and Its Branches

This line starts from Chensi and proceeds southwestward along the Tienshan pasture through Yenanpoa, Shihkialoong, and Taolaitse to Chikoching, then along the Tienshan forest through Wutungkwo, Tungyenchi, Siyenchi, and Olong to Sensien, where it crosses the Central Trunk line. After Sensien it proceeds along the northern edge of the Tarim Desert through Lakesun City and Shehchuan to Hora, where it crosses the Cherchen-Koria line. From Hora the line proceeds along the course of the Tarim River, passing by many new settlements, fertile regions, and virgin forests, to Bastutakelak, where it crosses the Ili-Hotien line. Thence it goes through Pachu to Kashgar where it meets the Urumochi-Iden line. After Kashgar it proceeds northwestward to the frontier where it ends. Attached to this line are two branches. The first branch proceeds from Hora southwestward through many oases to Cherchen. The second proceeds from Pachu southwestward along the Yarkand River to Sache and then westward to Puli near the frontier. This line including the branches covers a distance of about 1,600 miles. The total length of this entire system is about 16,000 miles. See general map.
