The accompanying sketch map will give some idea ofthe line. The Menam is the great river of Siam and isnavigable for large vessels. The Pra-sak is navigable forsmall rice-boats to Saraburi ; the Muck-lek and the Lambaare in no sense navigable. The Lamba is a tributaryof the Mekong, the great river of Cambodia. On the mapat the point /4 is a secondary summit, and at B is the mainsummit; the rock-cutting and heavy jungle are between. Ayiitli the points marked Cand D. The maximum grade is cent., to be equated for curvature; 15 curves areallowed. The features which differentiate this work from ordinaryrailroad construction are : 1. Transport of machinery, tools, etc., 8,000 miles ; thisis by sea. as large vessels can land at Bangkok. 2. Extreme unhealthiness of the country, especially thedistrict known as the Fire Gods Jungle, where all theheavy rock-work is. 3. Scarcity of labor, which is increased by superstition,by occasional interference ot petty officials, and by the factthat the natives can get along with scarcely any money,and consequently do not feel the necessity of earningwages. 4. The surprising density of the jungle and the entireabsence of roads for wheeled vehicles. That work can be carried on in Siam is already proved,this Korat line having been surveyed and located at a costof not much over $200 per mile, including preliminarywork and office expenses. L
