Down below in the boiler the rats were stirring. The busy patter upstairs had made them curious. The footfalls of the children, light and quick, made them pause and look at one another. They began to quiver and gibber. Then on a signal from their captain they poured forth from the boiler and came slithering up the cellar stairs in a column to see what was going on. In the kitchen they met a horde of cockroaches who had emerged from their dark ruins, led by a big bull roach. They too had been disturbed by the new vibrations.
