Earth roads, a pratical guide to earth road construction and maintenance.

The emphasis of the text is on proper control of water reaching the road, and on basic principles of soil conservation. Unorthodox methods such as the use of diversion banks, which are a major means of controlling erosion, are described, as well as lead-off drains, drifts, splashes, culverts, and precautions against silting. Low construction costs can be achieved by adopting low-speed natural alignments, using local labour-intensive building methods where possible, and minimising the cost of earth-moving by use of material along the line of the road. An appendix covers surveying techniques and equipment.
