AIR RAID PRECAUTIONS [To the Editor of TICE SPECTATOR.]

SIR,—In one of its usually logical "News of the Week" para- graphs, The Spectator last week compares the efficacy of air-raid wardens, in adding to the possibility of future war, to the influence of umbrellas on rainfall.

The phenomenon of rainfall occurs as the result of conditions at present outside human control. Consequently an umbrella is incapable of causing the clouds either to retreat or burst. War, on the contrary, only afflicts (or peace blesses) a world which wills it. And it is a fact of psychological science that in the realm of things amenable to control by the human will, expectation of something happening greatly increases the likelihood that it will actually happen.—Yours faithfully,

H. W. CHENEY.
