The conversation threatened to be a long one. Spence saw that and proposed to go on to the Casino with Helena, leaving the two clergymen with Llwellyn. It was when they had gone that the trio settled down completely. It resolved itself at first into a duologue between the two elder men. Gortre's knowledge was too general and superficial on these purely antiquarian matters to allow him to take much part in it. He sat sipping his coffee and listening with keen attention and great enjoyment to this talk of experts. He had not liked Llwellyn from the first and could not do so even now, but he was forced to recognise the enormous intellectual activity and power of the big, purring creature before him. Step by step the two archæologists went over the new discoveries being made in the ground between the City Wall of Jerusalem and the Hill of "Jeremiah's Grotto." They talked of the blue and purple mosaics found on the Mount of Olives, of all that had been done by the English and German excavators during the past years. Gradually the discussion became more intimate and began to touch on great issues. Mr. Byars was in a state of extraordinary interest. His knowledge was wide, and Llwellyn early realised this, speaking to him as an equal, but beside the Professor's all-embracing achievements it was as nothing. The clergyman learnt something fresh, some sudden illuminating point of view, some irradiating fact, at every moment. "I suppose," Mr. Byars said at length, "that the true situation of the Holy Sepulchre is still a matter of considerable doubt, Professor. Your view would interest me extremely." "My view," said Llwellyn, with remarkable earnestness and with an emphasis which left no doubt about his convictions, "is that the Sepulchre has not yet been located." "And your view is authoritative of course," said Mr. Byars. The Professor bowed.
