A light, sandy soil, well drained, will retain but a portion of the alkali from the irrigating water; but a dense adobe, holding a large amount of water, bringing water by capillary ac- tion from greater depths to the surface where it is evaporated, and draining with difficulty, accumulates much larger quantities of salts.
