"Of course," answered Lady Olivia, detaching from her belt the little leather bag in which she usually carried her handkerchief, scent-bottle, and other odds and ends. "_I_ think that several of them are quite good; but my husband declares that they are not worth the trouble of picking up." "And he is quite right, so far as this one, at least, is concerned," remarked the professor, as he drew forth a stone and held it up to the light for a moment. "This also," as he drew forth a second, looked at it, and threw it away. "Ah!" he exclaimed, as he produced a third, "this looks more promising." He examined the stone very carefully--it was about the size of a plover's egg--and presently said, as he handed it back-- "My dear lady, permit me to congratulate you. You have been fortunate enough to secure an exceptionally magnificent stone, without doubt. It is, of course, somewhat difficult to judge of the precise value of a gem in its rough, uncut state, but I should say that you have there a stone that will prove almost unique, not only as to size, but also for its perfect colour. Have you any more like it?" Further investigation proved that Lady Olivia had another that was almost, if not quite, the equal of the first, as well as three others of somewhat smaller size, but equal beauty of colour; and when, presently, the professor proceeded to examine Sir Reginald's find, it became at once apparent that the rubies to be found in this particular locality were likely to prove exceptionally valuable from their extreme richness of colour. "And these," exclaimed von Schalckenberg, enthusiastically, "are the results of but a few hours' search! Surely there must be a ruby mine of almost fabulous richness somewhere close at hand. Now is the time for me to acquire a little of that wealth of which I am in such urgent need." And, raising his hat to Lady Olivia, he turned away. But it was presently noticed that, instead of examining the pebbles on the beach, as the rest were doing, he went straight to the foot of the low cliff at the upper edge of the beach, scrutinising its face very closely, and foot by foot, as he passed slowly along it. When last particularly noticed, he was seen to be apparently digging into the soil of the cliff-face, here and there, with his pocket-knife.
