It is customary in the slums to leave the house door open perpetually, which is convenient for tramps, who creep into the hall-ways to sleep at night, thereby saving the few pence it costs to occupy a "spot" in the cheap lodging houses. Em and Mat keep the corridor without their room beautifully clean, and so it has become an especial favourite stamping ground for these vagrants. We were told this when Mattie locked and bolted the door and then tied the keys and the door-handle together. So we understand why there are shuffling steps along the corridor, bumping against the panels of the door, and heavily breathing without during the long hours of the night. All day Em and Mat have been toiling among their neighbours, and the night before last they sat up with a dying woman. They are worn out and sleep heavily. Liz and I lie awake and wait for the coming of the morning; we are too oppressed by what we have seen and heard to talk. In the morning Liz and I peep over into the rear houses where we heard those dreadful shrieks in the night. There is no sign of life, but we discover enough filth to breed diphtheria and typhoid throughout a large section. In the area below our window there are several inches of stagnant water, in which is heaped a mass of old shoes, cabbage heads, garbage, rotten wood, bones, rags and refuse, and a few dead rats. We understand now why Em keeps her room full of disinfectants. She tells us that she dare not make any appeal to the sanitary authorities, either on behalf of their own or any other dwelling, for fear of antagonizing the people, who consider such officials as their natural enemies.
