Light Railways. By C. B. Salwey. (E. and. F. N.

Spon.)—Mr. Salwey, who is a practical engineer, shows how and at what cost light railways may be made for exploring and military purposes. The precise point at which it will pay to construct a railway of this kind cannot be determined, except by a knowledge of' particular circumstances ; but there can be little doubt that this method of locomotion has not been utilised as extensively as it might have been. Mr. Salwey estimates the cost at an average ranging between -21,200 and 41,000 per mile, and calculates that 400 miles might be made in a year. How vast would be the benefit if, by aid of this means of travelling, we could dispense with the precarious system of porters in Africa !
