Upon the whole it was very good fooling,--for awhile; and as soon as we were tired of it we arose from our seats, and began to stroll about the place. It was beginning to be a little dusk, and somewhat cool, but the evening air was pleasant, and the ladies, putting on their shawls, did not seem inclined at once to get into the carriages. At any rate, Mrs. Talboys was not so inclined, for she started down the hill towards the long low wall of the old Roman circus at the bottom; and O'Brien, close at her elbow, started with her. "Ida, my dear, you had better remain here," she said to her daughter; "you will be tired if you come as far as we are going." "Oh, no, mamma, I shall not," said Ida. "You get tired much quicker than I do." "Oh, yes, you will; besides I do not wish you to come." There was an end of it for Ida, and Mrs. Talboys and O'Brien walked off together, while we all looked into each other's faces. "It would be a charity to go with them," said Mackinnon. "Do you be charitable, then," said his wife. "It should be a lady," said he. "It is a pity that the mother of the spotless cherubim is not here for the occasion," said she. "I hardly think that any one less gifted will undertake such a self sacrifice." Any attempt of the kind would, however, now have been too late, for they were already at the bottom of the hill. O'Brien had certainly drunk freely of the pernicious contents of those long-necked bottles; and though no one could fairly accuse him of being tipsy, nevertheless that which might have made others drunk had made him bold, and he dared to do--perhaps more than might become a man. If under any circumstances he could be fool enough to make an avowal of love to Mrs. Talboys, he might be expected, as we all thought, to do it now. We watched them as they made for a gap in the wall which led through into the large enclosed space of the old circus. It had been an arena for chariot games, and they had gone down with the avowed purpose of searching where might have been the meta, and ascertaining how the drivers could have turned when at their full speed. For awhile we had heard their voices,--or rather her voice especially. "The heart of a man, O'Brien, should suffice for all emergencies," we had heard her say. She had assumed a strange habit of calling men by their simple names, as men address each other. When she did this to Mackinnon, who was much older than herself, we had been all amused by it, and, other ladies of our party had taken to call him "Mackinnon" when Mrs. Talboys was not by; but we had felt the comedy to be less safe with O'Brien, especially when, on one occasion, we heard him address her as Arabella. She did not seem to be in any way struck by his doing so, and we supposed, therefore, that it had become frequent between them. What reply he made at the moment about the heart of a man I do not know;--and then in a few minutes they disappeared through the gap in the wall.
