Accumulatioa of alkali. — The alkali salts, being readily soluble, are carried by the soil water where there is any lateral movement, as is often the case where land slopes to some one point. Low-lying lands adjacent to such slopes are thus likely to contain considerable alkali, and the " alkali spots '^ of semiarid regions and the large accumulations of alkali in many of the valley lands of arid regions are traceable to this cause. 309. Irrigation and alkali. — In irrigated regions, the injurious effect of alkali is in many cases discovered only.
