This is a book of adventures in and about London: not a sociological pamphlet; but I do seriously feel that if I am writing on the subject at all, I may as well write the complete truth. I have heard, often, in this macabre street, the most piercing of all sounds that the London night can hold: a child's scream. The sound of a voice in pain or terror is horrible enough anywhere at night; it is twenty times worse in this district, when the voice is a child's. I want, very badly, to tell the story I refrained from telling. I want to tell it because it is true, because it ought to be told, and because it might shake you into some kind of action, which newspaper reports would never do. Yet I know perfectly well that if I did tell it, this book would be condemned as unclean, and I as a pornographist, if not something worse. So let our fatuous charity-mongers continue to supply Flannel Underclothing for the Daughters of Christian Stevedores; let them continue to provide Good Wholesome Meals for the Wifes of God-Fearing Draymen, and let them connive by silence at those other unspeakable things.

That lamp is shining the whole night through. The door that it lights is never closed day or night; it dare not close. Through the leafy gloom of the Square it shines--a watchful eye regarding the foulest blot on the civilization of England. It is the lamp of the office of the National Society for the Prevention of Cruelty to Children. This Society keeps five hundred workers incessantly busy, day and night, preventing cruelty to little English children. Go in, and listen to some of the stories that the inspectors can tell you. They can tell you of appalling sufferings inflicted on children, of bruised bodies and lacerated limbs and poisoned minds, not only in the submerged quarters but in comfortable houses by English people of education and position. Buy a few numbers of the Society's official organ, _The Child's Guardian_, and read of the hundreds of cases which they attack every month, and of the bestialities to which children are submitted, and you will then see that light as the beacon-light of England's disgrace. I once showed it to a Spanish friend, and he looked at me with polite disgust. "And your countrymen, my friend," he said, "speak of the Spaniards as cruel. Your countrymen, who gather themselves in dozens, protected by horses and dogs, to hunt a timid fox, call us cruel because
