" A MINE OF WEALTH "

[To the Editor of the SPECTATOR.]

Sia,—Like others I have been deeply interested in the article on " A Mine of Wealth," in the current issue of the Spectator, outlining so clearly some of the general factors connected with the proposed exploitation of the mineral wealth of the Dead Sea. Those of us who were faced with the problem of finding new means of producing potash when the usual supplies were cut off can hardly fail to be impressed by the prospect that it may perhaps be found possible to secure a new and almost inexhaustible source of this commodity.

Provided that such new supplies can be marketed cheaply and independently, their importance to agriculture can hardly be overestimated. At the same time, problems of the first magnitude appear to be involved—technical, financial, political, &c.—and, since the exploitation of the Dead Sea salts has now been under discussion for quite a long time, the examination of some of these problems should have reached a stage at which a fuller presentation of the facts might interest the public. The writer of the article in the Spectator is apparently familiar with much of the inner history of the developments which have taken place during the last few years ; at any rate it would be most valuable if his general presentation of the problem could be 'supplemented in this direction.—I am, Sir, &c.,

SCIENTIST.
