Useless, of course, it was, bothering to destroy a bridge in such a state; so we drew off quietly (not to alarm the workmen) walking over loose stones which turned under our bare feet in a way imposing care if we would avoid risk of sprain. Once I put my foot on something moving, soft and cold; and stepped heavily, on chance it was a snake; but no harm followed. The brilliant stars cast about us a false light, not illumination, but rather a transparency of air lengthening slightly the shadow below each stone, and making a difficult greyness of the ground.
