"whither are we tending," part of the answer will be that by such measures as this for the care of child life, which means in practice especially for the keeping alive of boys, we are tending toward the correction of one of the gravest, though least recognized, evils of the present day. Our business in the present volume is not with childhood. It is not possible to go fully into the statistical details of the comparative death-rate of the sexes, but the data can readily be obtained by any interested reader.[17] It may be argued that the questions now under consideration are foreign to a chapter entitled "The Conditions of Marriage," but the excess of women in a community is one of the most fundamental conditions of marriage therein, and the question is not the less necessary to be dealt with because, so far as one can ascertain, its consequences have escaped the notice of previous students. Having dealt with the waste of male life in infancy, in childhood and in war, we must pass on to a totally different factor of our problem, and that is the emigration to our colonies and elsewhere of a greatly disproportionate number of men. One does not assert for a moment that the men should not go, but merely that if they do, so should women also. As everyone knows they go for many reasons and purposes. These are largely industrial and imperial. The Civil Service claims a large number. These bachelors go in the cause of Empire, whether as actual servants of the State or in the interests of commerce. They are largely picked men, capable of discipline and initiative and of withstanding hardships; and also in large degree intellectually able. It is certainly not good for them to be alone, and it is worse for the women whom they leave behind. All this may seem right and the only practicable thing for the day, but it is fundamentally wrong because it is wrong for the morrow.
