In looking at the gradations of income among the working-classes, it must be borne in mind that as you go lower down in the standard of living, each drop in money income represents a far more than proportionate increase of the pressure of poverty. Halve the income of a rich man, you oblige him to retrench; he must give up his yacht, his carriage, or other luxuries; but such retrenchment, though it may wound his pride, will not cause him great personal discomfort. But halve the income of a well-paid mechanic, and you reduce him and his family at once to the verge of starvation. A drop from 25s. to 12s. 6d. a week involves a vastly greater sacrifice than a drop from £500 to £250 a year. A working-class family, however comfortably it may live with a full contingent of regular workers, is almost always liable, by sickness, death, or loss of employment, to be reduced in a few weeks to a position of penury. § 3. Measurement of East London Poverty.--This brief account of the inequality of incomes has brought us by successive steps down to the real object of our inquiry, the amount and the intensity of poverty. For it is not inequality of income, but actual suffering, which moves the heart of humanity. What do we know of the numbers and the life of those who lie below the average, and form the lower orders of the working- classes? Some years ago the civilized world was startled by the _Bitter Cry of Outcast London_, and much trouble has been taken of late to gauge the poverty of London. A host of active missionaries are now at work, engaged in religious, moral, and sanitary teaching, in charitable relief, or in industrial organization. But perhaps the most valuable work has been that which has had no such directly practical object in view, but has engaged itself in the collection of trustworthy information. Mr Charles Booth's book, _The Labour and Life of the People_, has an importance far in advance of that considerable attention which it has received. Its essential value is not merely that it supplies, for the first time, a large and carefully collected fund of facts for the formation of sound opinions and the explosion of fallacies, but that it lays down lines of a new branch of social study, in the pursuit of which the most delicate intellectual interests will be identified with a close and absorbing devotion to the practical issues of life. In the study of poverty, the work of Mr. Booth and his collaborators may truly rank as an epoch-making work.
