ORIGIN, OCCURRENCE, AND CORRECT IDENTIFICATION OF LATERITE ROCK AND SOIL ARE BRIEFLY DISCUSSED. THE PECULIAR PROPERTIES OF LATERITE SOILS ARE OUTLINED AND SUGGESTED METHODS OF DEALING WITH THEM INDICATED. RESULTS ARE REPORTED OF EXPERIMENTAL STUDIES ON FOUR LATERITE SOILS AND ONE INTRAZONAL NON-LATERITE SOIL, WITH SPECIAL ATTENTION TO THEIR SUSCEPTIBILITY TO STABILIZATION. THE LATTER VARIED OVER A WIDE RANGE. OF THE STABILIZERS USED, PORTLAND CEMENT GAVE BEST RESULTS IN SOME CASES AND ANILINE-FURFURAL (2:1) IN OTHERS. THE PRESENCE OF ORGANIC MATTER SEEMS TO PLAY A DETRIMENTAL ROLE IN MANY CASES. THE POSSIBLE USE OF OILED EARTH PROPERLY FORTIFIED WITH ANTI-OXIDANTS AND BACTERICIDAL SUBSTANCES FOR LOW-COST ROADS IN LATERITE AREAS IS BRIEFLY DISCUSSED. /AUTHOR/
