In doing this, however, it was pre-eminently a case of looking to virtue as its own reward. Certainly it brought him no nearer the realisation of his hopes; for so slender were his private means of existence, that only by the exercise of the most rigid economy could he get along at all, and the necessaries of life, be it remembered, were at famine prices. Decidedly, indeed, his prospects were looking blacker and yet more black. And what of Nidia herself? As the days went by she seemed to draw no nearer. Seldom now was he suffered to be alone with her, and then only for a minute or so, when an ever-present feeling of _gene_ and flurry would be there to mar the effect of any opportunity he might have had to improve the occasion, and, indeed, he was beginning to regard matters as hopeless. The persistent hostility of Mrs Bateman was ever on the watch to defeat his every move; and as to this, even, there were times when it seemed to him that Nidia was a trifle too acquiescent in the latter's objectionable and scarcely concealed efforts at railing him off. Then, too, Nidia was constantly surrounded by a knot of men, many of them fine gallant-looking fellows, already distinguished for some feat of intrepidity. There was the commander of the relief troop which had brought her in, for instance, and Carbutt and Tarrant and several others. He, John Ames, so far from being the one to bring her in, as he used to pride himself would be the case, had merely imperilled her the more by his own sheer incautious blundering. Sick at heart, he would fain be lying where he had fallen--a battered, lifeless heap at the base of the great _dwala_. From this his thoughts would wander to the mysterious rock-dwelling, and to him who inhabited it. Why, and with what object to serve, had the Umlimo spared and tended him? That he might deliver his message to the outside world? Well, he had done that. And then--and the very thought sent a thrill as of needles and pins throughout his whole system. He had delivered the one message, but what of the other enclosure, the one which in some mysterious way concerned himself, the packet marked "B"? He got it out and eyed it. The Umlimo's words were vividly imprinted in his memory. "The time may come when you will see everything dark around you, and there is no outlook, and life hardly worth prolonging. Then, and then only, open it."
