As he spoke he waved his hand in the direction of a rug which lay upon the floor.

On the rug stood a long, shallow fruit-basket of the light wicker-work which is used in the Campagna, and this was heaped with a litter of objects, inscribed tiles, broken inscriptions, cracked mosaics, torn papyri, rusty metal ornaments, which to the uninitiated might have seemed to have come straight from a dustman’s bin, but which a specialist would have speedily recognized as unique of their kind.

The pile of odds and ends in the flat wicker-work basket supplied exactly one of those missing links of social development which are of such interest to the student. It was the German who had brought them in, and the Englishman’s eyes were hungry as he looked at them.

“I won’t interfere with your treasure-trove, but I should very much like to hear about it,” he continued, while Burger very deliberately lit a cigar. “It is evidently a discovery of the first importance. These inscriptions will make a sensation throughout Europe.”

“For every one here there are a million there!” said the German. “There are so many that a dozen savants might spend a lifetime over them, and build up a reputation as solid as the Castle of St. Angelo.”

Kennedy was thinking with his fine forehead wrinkled and his fingers playing with his long, fair moustache.

“You have given yourself away, Burger!” said he at last. “Your words can only apply to one thing. You have discovered a new catacomb.”

“I had no doubt that you had already come to that conclusion from an examination of these objects.”

“Well, they certainly appeared to indicate it, but your last remarks make it certain. There is no place except a catacomb which could contain so vast a store of relics as you describe.”

“Quite so. There is no mystery about that. I have discovered a new catacomb.”
