RESTRICTED POPULATION [To the Editor of THE SPECTATOR.]

Sin,—In his last letter " Unemployed " writes : " One cannot tamper with the sexual and procreative instincts " : in other words, those instincts are sacrosanct.

Over-production of population is the most serious over-production from which we are suffering, and as long as men are at the mercy of an uncivilized reproductive instinct there is little hope for the future. Only by controlling the output of population, and by as far as possible safeguarding its quality, can the country be saved. Birth control alone offers salvation to the working classes, yet they are very slow in accepting it, largely owing to the attitude revealed in the letter of " Unemployed."—I dm, Sir, &c., Compton, Wolverhampton. - - MARGARET SPARROW.
