“Impossible! A foolish risk, Sergeant, that I am unwilling you should take. Edinburgh is too full of pitfalls for a man to be going about on such a night. Our guests will sleep in the Castle, and it will be safer for the little dog to remain until morning.” Bobby did not quite understand this good English, but the excited talk and the delay made him uneasy. He whimpered piteously. He lay across the sergeant's feet, and through his boots the man could feel the little creature's heart beat. Then he rose and uttered his pleading cry. The sergeant stooped and patted the shaggy head consolingly, and tried to explain matters. “Be a gude doggie noo. Dinna fash yersel' aboot what canna be helped. I canna tak' ye to the kirkyaird the nicht.” “I'll take charge of Bobby, Sergeant.” The dog-loving guest ran out hastily, but, with a wild cry of reproach and despair, Bobby was gone. The group of soldiers who had been out on the cliff were standing in the postern a moment to look down at the opaque flood that was rising around the rock. They felt some flying thing sweep over their feet and caught a silvery flash of it across the promenade. The sergeant cried to them to stop the dog, and he and the guest were out in time to see Bobby go over the precipice. For a time the little dog lay in a clump of hazel above the fog, between two terrors. He could see the men and the lights moving along the top of the cliff, and he could hear the calls. Some one caught a glimpse of him, and the sergeant lay down on the edge of the precipice and talked to him, saying every kind and foolish thing he could think of to persuade Bobby to come back. Then a drummer boy was tied to a rope and let down to the ledge to fetch him up. But at that, without any sound at all, Bobby dropped out of sight. Through the smother came the loud moaning of fog-horns in the Firth. Although nothing could be seen, and sounds were muffled as if the ears of the world were stuffed with wool, odors were held captive and mingled in confusion. There was nothing to guide a little dog's nose, everything to make him distrust his most reliable sense. The smell of every plant on the crag was there; the odors of leather, of paint, of wood, of iron, from the crafts shops at the base. Smoke from chimneys in the valley was mixed with the strong scent of horses, hay and grain from the street of King's Stables. There was the smell of furry rodents, of nesting birds, of gushing springs, of the earth itself, and something more ancient still, as of burned-out fires in the Huge mass of trap-rock.
