"Just shut down that throttle, Marsden," he called cheerily to the man operating the engine; and then to one of the sailors right for'ard: "You can let go that anchor, Clark. Now, boys, we'll pipe down to a meal and a smoke of tobacco, for there's no violent hurry. Glad to meet you two young officers. I'm Commander Houston, lately of H.M.S. ——, the ship the Admiralty authorities in Whitehall insisted on keeping in the Persian Gulf—a nasty sort of a place that Persian Gulf, I can tell you. Aboard-ship life in those parts is worse than any 'hole in Calcutta', and when the hot weather comes, phew! it's a wonder that a white man survives, and to me it's a miracle that I remain so robust and stout, when you'd expect me to get as thin as a lath, and waste away rapidly."

Waste away indeed! No one who cared to look at the jovial Commander Houston would ever imagine that to be possible, to have been probable even at any stage in his career. For the man was heavily built, as we have said, his bones well covered with muscle, and the latter clad with an amount of fat which made his figure rather rounder than was desirable. Geoff smiled back at him, while Philip unbent and let himself go in a moment. They couldn't help themselves, for the Commander made them feel at ease almost immediately. His smiling crew, the oil-stained individual who worked his engine, the Cox who sat right aft with the tiller, every one of them smiled, as if happy to be in his company.

"Looks jolly promising," Philip told his chum sotto voce, "It never occurred to me before that in joining this expedition we might have found ourselves under a high and mighty sort of fellow, who would order us about like dirt, just because we're junior subalterns. Ahem! Breakfast? Rather!"

"And to think that we had a meal just before we left our side of the river," said Geoff; "but I'm hungry enough, and ready for anything."

By now the Cox had gone for'ard, where the tall, raw-boned, grey-bearded native—whom Geoff had interviewed on the previous day, and who was said to have an intimate knowledge of the marshes—had now joined them. The Commander himself came aft from the central cabin, in which he had been stationed, and sat himself down near the two young infantry officers, and, opening a locker, pulled out a basket of provisions.

"The man who wants to get on in the world, and carry out a job successfully, must look after his health whatever happens," he smiled at them. "So, having started this expedition successfully, and slipped into the marshes with, I feel sure, no one being the wiser, we can look after the inner man before proceeding farther. Which one of you young officers happens to be known as Geoffrey Keith?"

"Guilty, sir!" Geoff told him, with a laugh. "I am the individual."

"Oh!"

At once our hero felt himself being surveyed with that same sort of polite, yet searching scrutiny which the General and his Staff Officers had directed upon him. Perhaps it is a habit of the Services; more likely it is a habit engendered in men placed in a position of command, who wish, in the space of a few seconds—seeing that often enough there is no longer for the purpose—to sum up those who are to serve with them, those upon whom they may have to call for action, and to assure themselves at the very commencement that they are to be fully relied upon.

"Oh!" he said at last, as he dived into his basket and produced a Thermos bottle, some cups, and a paper parcel. "Young enough, at any rate, Keith, but they tell me not too young to stand fire. Ah! Ah! Tales do spread, don't they? Never saw such people as the army for gossiping! I give you my word that, long before this expedition was mooted, I knew all about a fellow with a thundering fine Arab who had gone out and captured an Arab chief. That's you, eh, Keith?"
