Pulling his long boots off and his breeches higher up his legs, he was over the side in a twinkling, while the crew, enjoying the experience amazingly, followed him, Phil helping to set an example.

"Now, all together, boys!" shouted Geoff. "Pull her off! Pull her back! That's done it; she's moving!"

Not once, but half a dozen times, in the next two or three days, were they forced to extricate themselves from a similar sort of situation by similar methods. For, let us explain, there was no opportunity to take careful account of the obstacles before them, to steer a slow and cautious course, and to make a complete reconnaissance of the route they were to follow. Under ordinary conditions, with time at their disposal, Geoff would have steered his launch at a placid pace, and would have avoided enclosed waters where islands of mud abounded; but now, with this expedition, it was a case of each man for himself, of push ahead all the time. It was a race, in fact, a friendly race, between the army and the navy, each service vying with the other in its efforts to push onward, and each secretly determined to get to the goal before the other.

"If we don't look out we shall be running our heads into a hornets' nest," Geoff cried irritably, when, for the fifth time at least, he and his crew had had to leap into the shallow water and pull their vessel free of a mud-bank. "This sort of headlong course will not help us to beat the enemy, but will give them an enormous opportunity."

Whereat Phil grinned. He was one of those incautious, careless, happy-go-lucky sort of subalterns who never think of consequences, and who, perhaps for that very reason, so seldom come to grief. Perhaps it was a lucky star which always watched over Phil's progress, for, in any case, happy-go-lucky though he was, careless to an irritating degree, he yet had so far come through many a little adventure unscathed.

"Tremendous opportunity—yes!" he told Geoff. "But—but will they take it? Bet you they're already thinking of bolting; for don't forget, my boy, we've given them a pretty hard hammering. Besides, an expedition such as this is, spread out through the marshes, ain't so jolly easy to tackle. You could stop a portion, perhaps—say one flank, or the portion in the centre of the ground, or rather the water. What do you Head-quarters chaps call it? It would be called terrain if it was a question of land operations, and I don't happen to know the term under these conditions. But that's what might happen; one portion of our spread-out front might get stopped, but the others would push on like blazes! Cheer up, Geoff! It'll all come right, and you'll earn promotion yet."

It always ended like that with such a fellow as Phil, and Geoff, cautious and earnest young officer though he was, was forced to laugh uproariously, and join in Phil's merriment. And, after all, if caution had been thrown to the winds by all of them—which was far from being the case—caution on his part would hardly remedy the situation. Pushing on, therefore, and taking the most out of his steam-launch, thrashing her across every open strip of water till her bow waves washed almost aboard, and until the rope to which the bellums were attached was drawn like a bow-string, and the unfortunate individuals aboard those craft drenched with spray, he wriggled his way forward with other boats of the expedition, determined to be well in the van at the coming conflict. Then, as the dusk fell, and the boats tied up or anchored for the night, he selected a likely spot towards the edge of the marshes, and dropped anchor. Entering a bellum, he went off towards one of the bigger craft, aboard which the Staff conducting this extraordinary expedition were quartered.

"What's up?" asked Philip on his return, the inevitable question that young officer fired at his comrade. "Of course, everyone knows that we're jolly near this Nasiriyeh, so to-morrow there'll be something doing, eh?"

"Come over here," Geoff said, nodding towards the stern of the vessel.

"Secrets, eh?" grinned Philip, yet wonderfully eager to hear what Geoff had to say. "Now then, what's the business?"
