That they will do so I regard as certain, seeing that the house is not built for purposes of defence, but has numerous broad windows on the ground-floor by which assuredly they will burst their way in.
"Wait a moment then, Ralph; let us run up to the top storey and see if there be any means of escape along the roofs." The house stood detached from the others, but on one side was separated from that next to it only by a narrow lane, and as the upper stories projected beyond those below, the windows were but six feet distant from those on the opposite side of the way.
"See," Water said, "there is a casement in the room to our left there which is open; let us see if it is tenanted." Going into the next room they went to the window and opened it.

It exactly faced the casement opposite, and so far as they could see the room was unoccupied.
"It were easy to put a plank across," Ralph said.
"We must not do that," Walter answered.

"The mob are thick in the lane below--what a roar comes up from their voices!--and a plank would be surely seen, and we should be killed there as well as here.

No, we must get on to the sill and spring across; the distance is not great, and the jump would be nothing were it not that the casements are so low.

It must be done as lightly and quickly as possible, and we may not then be seen from below.
