The capillary action goes on; and as the pure water is taken off in the atmosphere in vapour, other water impregnated with more salts comes up to supply its place; and the salts near the surface either accumulate or are supplied to the roots of the plants, shrubs, or trees, which require them.
[* Caused, possibly, by the Vendeya range once extending E.N.

E.up to the Himmalaya chain, which runs E.S.

E.It now extends up only to the right bank of the Ganges, at Chunar and Mirzapoor.] Rain-water,* which contains no such salts, falls after the dry season is over, and washes out of the upper surface a portion of the salts, which have thus been brought up from below and accumulated, and either takes them off in floods or carries them down again to the beds below.

Some of these salts, or their bases, may become superabundant, and render the lands oosur or unfit for ordinary tillage.

There may be a superabundance of those which are not required, or cannot be taken up by the plants, actually on the surface, or there may be a superabundance of the whole, from the plants and rain-water being insufficient to take away such as require to be removed.
