The cost of transiDortatiyn must in must cases be re-duced by increasing the size of the load. This increasein the size of the load can be brought about in Iwnways: by redncing the grades, and by improving thesurface. Steep hills necessitate a reducti:)n in tlie size of theload and so increase the cost of hauling.
