It is necessary to organise rescue expeditions to free the miserable wanderers from their captivity, and bring them out into the larger liberty and the fuller life. Talk about Stanley and Emin! There is not one of us but has an Emin somewhere or other in the heart of Darkest England, whom he ought to sally forth to rescue. Our Emins have the Devil for their Mahdi, and when we get to them we find that it is their friends and neighbours who hold them back, and they are, oh, so irresolute! It needs each of us to be as indomitable as Stanley, to burst through all obstacles, to force our way right to the centre of things, and then to labour with the poor prisoner of vice and crime with all our might. But had not the Expeditionary Committee furnished the financial means whereby a road was opened to the sea, both Stanley and Emin would probably have been in the heart of Darkest Africa to this day. This Scheme is our Stanley Expedition. The analogy is very close. I propose to make a road clear down to the sea. But alas our poor Emin! Even when the road is open, he halts and lingers and doubts. First he will, and then he won't, and nothing less than the irresistible pressure of a friendly and stronger purpose will constrain him to take the road which has been opened for him at such a cost of blood and treasure. I now, therefore, proceed to sketch some of the methods by which we shall attempt to save the lost and to rescue those who are perishing in the midst of "Darkest England." SECTION 1.--A SLUM CRUSADE.--OUR SLUM SISTERS. When Professor Huxley lived as a medical officer in the East of London he acquired a knowledge of the actual condition of the life of many of its populace which led him long afterwards to declare that the surroundings of the savages of New Guinea were much more conducive to the leading of a decent human existence than those in which many of the East-Enders live. Alas, it is not only in London that such lairs exist in which the savages of civilisation lurk and breed. All the great towns in both the Old World and the New have their slums, in which huddle together, in festering and verminous filth, men, women, and children. They correspond to the lepers who thronged the lazar houses of the Middle Ages.
