ABSTRACT
The colonies and dependencies of the Crown offer a field of vast extent supporting a population of many millions of prospective buyers. Both roads and railways will be needed, and, in order that funds allocated for their construction may be spent to the best advantage, it is necessary to determine how each form of transport can best be utilized to provide the facilities required. In the African colonies most of the roads are of the ‘earth’ or ‘dirt’ type, and only a comparatively small mileage has been provided with a metal or gravel surface, while only a small proportion of the metalled roads have received tar treatment. A macadam road is difficult to maintain under tropical conditions for modern high-speed heavy traffic, as the binding material is sucked out and the heavy rains of the wet season disintegrate the surface.
