This is a short story book. A long, green wave ran up, gleaming like curved glass in the sunlight, and broke in a million sparkles against a shelf of shingle. Above the shingle rose the soft cliffs, clothed with scrubby grass and crowned with gorse. Columbus wagged a cheery tail and expressed complete agreement. He was watching a small crab hurrying among the stones with a funny frown between his brows. He was not quite sure of the nature or capabilities of these creatures, and till he knew more he deemed it advisable to let them pass without interference. A canny Scot was Columbus, and it was very seldom indeed that anyone ever got the better of him. He was also a gentleman to the backbone, and no word his mistress uttered, however casual, ever passed unacknowledged by him. He always laughed when she laughed, however obscure the joke.
