"Bless my soul, Manners!" exclaimed the colonel turning to the adjutant. "What does this mean?"
"Dunno, sir, I'm sure," answered the dum-founded officer.
"We can't let the affair drop," decided the C.O. "It's not fair on MacGregor to sit still. Tell off a section and follow the horse's tracks. Perhaps the man has been wounded—it looks very much like it—and may be lying out in the bush."
Promptly Bela Moshi and about a dozen men were dispatched to follow up the spoor. Good trackers all, they ought to experience but little difficulty, notwithstanding the fact that hundreds of men had been trampling the ground, for the Haussas vie with the Australian aborigines and the Red Indian in the act of tracing a man or an animal for miles with uncanny skill and persistence.
Hardly had the Haussas departed on their errand when a couple of British naval officers literally staggered into the bivouac. At first they were too utterly done up to speak. They were parched with thirst, their drill uniforms torn in their long trek through the scrub, and their boots were cut almost to pieces. One of them was limping badly as the result of a sprained ankle.
Under the care of Doctor Barclay the stragglers soon recovered sufficiently to give a coherent account of their misadventures. They were the observer and pilot of one of the seaplanes attached to the Rovuma column, their base being close to a large sheet of water formed by the inundation of the river. Out reconnoitring they had discovered a party of Huns and had bombed them very effectually. That was their version, although Wilmshurst had good reason to believe that they were quite under a misapprehension on that score. On the return flight the engine developed ignition troubles, and there was no help for it but to plane down. The airmen were lucky in being able to find a fairly open stretch of ground, but the unexpected happened. The floats of the seaplane skidded over the hard ground and caught against some obstruction, with the result that the machine was badly damaged, the pilot and observer being thrown violently.
Forty miles from their base the airmen realised that it was almost out of the question to make their way on foot through the scrub, especially as there were several small rivers to be negotiated. So they decided to find the bivouac of the Waffs which they had spotted on their outward flight. According to their estimate the distance was about eight miles, but in reality it was almost twice that distance.
Owing to the intense heat they were compelled to discard their overalls. Their foot gear was totally inadequate against the thorns and stony ground. Without water and with only a bar of chocolate between them they experienced terrible hardships before they sighted their temporary refuge.
Their chief anxiety was now the question whether the seaplane could be recovered. On this score their minds were set at rest, when the colonel promised to send out a fatigue party to dismantle the machine and transport it to the banks of the Runkoma, a small stream sufficiently wide to allow the seaplane to taxi provided the floats were still intact.
"You might take that job on, Mr. Wilmshurst," remarked his company commander. "Your platoon will be just about sufficient to provide the necessary labour, and also a covering party, although I don't contemplate any trouble from the Huns. We've just heard that Fritz has had a nasty smack at Motungba, which more than counterbalances his recent success against the Portuguese on the Rovuma."
