It had turned out that McKechnie was actually the nephew of Tietjens' very old intimate, Sir Vincent Macmaster, of the Department of Statistics, being the son of his sister who had married the assistant to the elder Macmaster, a small grocer in the Port of Leith in Scotland. . . . That indeed had been why Campion had been interested in him. Determined as he was to show his godson no unreasonable military favours, the general was perfectly ready to do a kindness that he thought would please Tietjens. All these pieces of information Tietjens had packed away in his mind for future consideration and, it being after four-thirty before McKechnie had calmed himself down, Tietjens had taken the opportunity to inspect the breakfasts of the various fatigues ordered for duty in the town, these being detailed for various hours from a quarter to five to seven. It was a matter of satisfaction to Tietjens to have seen to the breakfasts, and inspected his cook-houses, since he did not often manage to make the opportunity and he could by no means trust his orderly officers. At breakfast in the depot mess-hut he was detained by the colonel in command of the depot, the Anglican padre and McKechnie; the colonel, very old, so frail that you would have thought that a shudder or a cough would have shaken his bones one from another, had yet a passionate belief that the Greek Church should exchange communicants with the Anglican: the padre, a stout, militant Churchman, had a gloomy contempt for Orthodox theology. McKechnie from time to time essayed to define the communion according to the Presbyterian rite. They all listened to Tietjens whilst he dilated on the historic aspects of the various schisms of Christianity and accepted his rough definition to the effect that, in transubstantiation, the host actually became the divine presence, whereas in consubstantiation the substance of the host, as if miraculously become porous, was suffused with the presence as a sponge is with water. . . . They all agreed that the breakfast bacon supplied from store was uneatable and agreed to put up half a crown a week a piece to get better for their table.
