AUTARKY AND " INSURANCE " SIR,—In her review of my

book, Light Out of Darkness, Honor Croome raises a point of fundamental importance upon which I should like to comment briefly.

Dealing with my contention that the interdependence of nations in trade is a source of instability, she states that this belief "is contrary to all the laws of probability in the mathe- matical sense, and, among other things, makes nonsense of the whole principle of insurance." Here, I feel, her criticism rests upon an unsound analogy. For a nation to increase its dependence upon other nations, instead of working towards economic self-sufficiency, is surely not strictly comparable with the insurance policy of "spreading the risk." If it were, the relative stability of the nations enjoying a high degree of self-sufficiency would be difficult to explain.—Yours faithfully,

CLARENCE C. HATRY.
