"Don't you think it!" he told him, his face now serious. "The average fellow seems to have got hold of the idea that the Turk is a lazy, idle, good-for-nothing, easy-going beggar, who'll hold up his hands and go under immediately war is declared on him. Why, I was reading a paragraph in the paper last evening which told us that Turkey was committing suicide by joining forces with Germany, and that Russia and England between them would mop her up and sweep her out of Europe."

Philip looked puzzled. When he said he had no great affection for geography, and had no particularly good bump of locality, he told his chum only the bare truth. To be quite candid, and yet essentially friendly with reference to Geoff's friend, we have to say that not even Geoff could have described this young officer as brilliant. He was just a gay, light-hearted, and, when he liked, an energetic and useful officer. When he liked to apply himself to his profession, or indeed to any other work of not too exacting a character, Philip could do as well as any other, though, to be sure, he did not shine as a rule. As a soldier, he was no better and no worse than his fellows, only his gayness of heart and his natural dash and courage might easily, under circumstances of exceptional stress, bring him to the fore and make him conspicuous. But, to speak bluntly, Philip was a bit of a dunce, and had lived his short life so far without taking extraordinary notice of his immediate surroundings, and of the world in general.

"Half a mo'!" he said, blowing a cloud of smoke in Geoff's direction. "What's that? Turkey in Europe! But Mesopotamia's Asia, isn't it? Here's a pencil, my boy, and here's a copy of to-day's 'orders'. Just you sketch out on the back of it the outline of Mesopotamia. I'm not such a fool that I can't follow a sketch when it's made for me."

A brother "sub" joined them at that moment, and as Geoff sketched diligently and drew in the outline of the Persian Gulf, of the Afghan frontier, and of Persia, another and yet another subaltern strolled up, till, quite unknown to him, a little group of officers were looking on over his shoulder. Then he suddenly became aware of their presence, and, colouring furiously, for the young fellow was essentially modest, he crumpled the paper up and threw it into a corner.

"No you don't, my boy! No you don't!" said a well-known voice from behind his shoulder. "We are all of us keen on knowing something more about the place we are bound for, and you are the only one amongst us who has ever been there. Take it as an order, Geoff. I'll guarantee that there shall be no larking, and I'm sure that every one of your brother officers wishes you to give us just a short lecture on the country called Mesopotamia."

Under the circumstances it was not to be expected that a junior officer, so junior indeed as Geoff, could refuse the request—the order if you like to call it, though it was given so pleasantly—of one of his seniors. It was the senior captain, in fact, who was leaning over his shoulder, and who patted his arm encouragingly.

"Fire ahead, Geoff," he told him. "It's not showing off! There's no swank about it! I'd like awfully to know all about this Mesopotamia. I'll admit the fact, before you young officers, that I'm just about as ignorant as I can be. Up to now I never imagined that there were any Turks to speak of in the neighbourhood of the Persian Gulf, so why on earth they should send an Expeditionary Force there from India is more than I can guess at. The Colonel says it's so that we shall protect the oil-supply which comes down from Persian territory to somewhere near the Gulf. Know it, Geoff?"

"Yes, sir! And if you really won't think it's swank——"

"Of course not. Now, here's a piece of paper, and get on with it."
