He did not witness the meeting between his little charge and her aunt. He bade farewell to a tearful, half-frightened little Madelon at the door of the parlour, he saw it close upon her, and it was with quite a heavy heart that he turned away, leaving behind him the little girl who had occupied so large a share of his thoughts and anxieties during the last ten days. He had nothing to detain him in Liege now, and he left it the next morning, with the intention of carrying out as much of his proposed tour as he should find practicable. His original intention had been to proceed from Paris to Strasbourg, and so into Switzerland, and over the Alps to the Italian lakes. So much of his holiday was already gone, however, that he gave up the idea of the lakes; but Switzerland might still be accomplished, and Strasbourg at any rate must be in his first point, as it was there that, on leaving England, he had directed his letters to be sent in the first instance, and he expected to find them lying awaiting them. He did find them, and their contents were such as to drive all thoughts of his tour out of his head. It was with a wild throb of excitement and exultation, such as he had never known before, that, on opening the first that came to hand, one that had been lying there for nearly a week, he read that the regiment to which he was attached was under immediate orders for the Crimea, and that he must return, without loss of time, to England. Even then, however, he did not forget little Madelon. He knew that she would be counting on his promised return, and could not bear the idea of going away without seeing her again, and wishing her good-bye. He calculated that he had still half a day to spare, and, notwithstanding his hurry, resolved to return by Brussels rather than Paris, choosing those trains that would allow him to spend a couple of hours in Liege, and pay a visit to the convent. It was only three days since he had last seen the white walls and grey roofs that were growing quite familiar to him now, and yet how life seemed to have changed its whole aspect to him--and not to him only, perhaps, but to somebody else too, who within those walls had been spending three of the saddest, dreariest days her small life had ever known. When Graham asked for Madelon, he was shown, not into the parlour, but into a corridor leading to it from the outer door; straw chairs were placed here also, on either side of the grating that divided it down the middle, and on the inner side was a window looking into another and smaller courtyard. As Graham sat there waiting, an inner door opened and a number of children came trooping out; they were the _externes_, children of the bourgeois class for the most part, who came to school twice a-day at the convent; indeed they were the only pupils, the building not being large enough to accommodate boarders.
