It was now quite dark, and we had great difficulty in making our way; there was a risk of finding ourselves at the edge of some chasm, down which we might fall.  The distance seemed very long, and I thought we must have missed the Coastguard station, which was situated at the edge of the cliffs.  At length, however, we saw a light gleaming from a window, and arrived at the wall which enclosed the house where the lieutenant and his men lived.  We found them on the alert.  Two had just gone off for some horses to drag the waggon in which the rocket apparatus was to be carried, as one of the men stationed to the southward had seen the brig and reported her danger.
