Morgan advanced a few steps farther, examined the wall, apparently in search of a familiar spot, then, having found it, inserted the tip of his boot in a cleft between two stones.

He sprang up like a man mounting a horse, seized the top of the wall with the left hand, and with a second spring seated himself astride the wall, from which, with the rapidity of lightning, he lowered himself on the other side.

All this was done with such rapidity, such dexterity and agility, that any one chancing to pass at that instant would have thought himself the puppet of a vision.
