By Fred’s direction they landed a little way from the point, from which three of the rocks were distant but half a gun-shot, being, indeed, connected with the point at low water, the extremity of which was fringed with low bushes, through which they crawled in different directions, when they found that the rocks were as Fred had said--blue with birds. It was arranged that Fred should caw like a crow in succession; at the first summons they were to get ready; at the second, Charlie and John were to fire; but Fred was to fire as they rose.
