I found myself in a lodging-house, now pulled down and replaced by one of Lord Rowton's tenement houses.

I saw a hundred human beings more or less huddled together promiscuously, and the face of every one of them was like the face of a rat.

The old man dragged me from room to room, laughing all the time.

He showed me children herded together without distinction of sex or clothing, here and there he pointed to a face where some apprehension of the light was fighting a losing battle with the ghouls of disease, of vice, of foul air, of filth.

I was faint and giddy when we had looked over that one house, but the old man was not satisfied.
