My task is perhaps too serious a one even for the light tone of these remarks. No man who has seen 'How the Poor Live' can return from the journey with aught but an aching heart. No man who recognises how serious is the social problem which lies before us can approach its consideration in any but the gravest mood. Let me, then, briefly place before the reader the serious purpose of these pages, and then I will ask him to set out with me on the journey and judge for himself whether there is no remedy for much that he will see. He will have to encounter misery that some good people think it best to leave undiscovered. He will be brought face to face with that dark side of life which the wearers of rose-coloured spectacles turn away from on principle. The worship of the beautiful is an excellent thing, but he who digs down deep in the mire to find the soul of goodness in things evil is a better man and a better Christian than he who shudders at the ugly and the unclean, and kicks it from his path, that it may not come between the wind and his nobility. But let not the reader be alarmed, and imagine that I am about to take advantage of his good-nature in order to plunge him neck-high into a mud bath. He may be pained before we part company, but he shall not be disgusted. He may occasionally feel a choking in his throat, but he shall smile now and again. Among the poor there is humour as well as pathos, there is food for laughter as well as for tears, and the rays of God's sunshine lose their way now and again, and bring light and gladness into the vilest of the London slums. His Royal Highness the Prince of Wales, in his speech at the opening of the Royal College of Music some years ago, said: 'The time has come when class can no longer stand aloof from class, and that man does his duty best who works most earnestly in bridging over the gulf between different classes which it is the tendency of increased wealth and increased civilization to widen.' It is to increased wealth and to increased civilization that we owe the wide gulf which to-day separates well-to-do citizens from the masses. It is the increased wealth of this mighty city which has driven the poor back inch by inch, until we find them to-day herding together, packed like herrings in a barrel, neglected and despised, and left to endure wrongs and hardships which, if they were related of a far-off savage tribe, would cause Exeter Hall to shudder till its bricks fell down. It is the increased civilization of this marvellous age which has made life a victory only for the strong, the gifted, and the specially blest, and left the weak, the poor, and the ignorant to work out in their proper persons the theory of the survival of the fittest to its bitter end.
