Hunter looked down. The machine was rapidly dropping towards the edge of the lake a little to the east of the Maritza River. Suddenly, while yet some distance from the ground, the aviatik’s descent was averted, possibly by an air pocket over the lake. For a moment it seemed poised without motion, then it turned a somersault. The observer fell out, and dropped into the lake at the same instant as the machine crashed on to the bank. Meanwhile Burton had circled round. His tank was nearly empty. He must either come down or fall down. There was no sign of life in the wrecked aeroplane; the observer had disappeared in the water; no one was in sight. Swinging round again Burton adjusted his elevator so as to descend on the lake, and in a few seconds the seaplane was resting on the surface within thirty yards of the spot where the aviatik lay, a mangled heap, on the bank. III "We can wade ashore," said Burton. "I can see the bottom." "Hadn’t we better mend the leak?" Hunter suggested. "But I want to see if the German has any spare petrol. We’ve lost a lot." They waded through a foot or two of water, and examined the wreck. One of the wings was crumpled up; otherwise the machine had suffered little injury. The pilot, a fair-haired German of Saxon type, was dead. There was plenty of petrol in the tank, and Hunter drew this off into a tin can while Burton returned to the seaplane, pulled it ashore, and set about discovering the leak. It turned out to be a long thin crack on the underside of the tank. "How on earth are we to mend this?" said Burton, looking at it ruefully. "Why not stuff it up with mud?" said Hunter. "This stuff at the edge of the lake seems to be clayey, and it will harden in no time." "Good! It may last for the few miles we have still to cover. Just keep a lookout while I work at it." Hunter went up the bank. A rough bridle-track skirted the lake and disappeared in a plantation that came down to within about a hundred yards of the water. To the south the view was shut in by a wooded knoll. There was neither man nor house in sight. Burton had just kneaded some clay for stopping up the crack when they heard shouts in the distance, apparently from a southward direction. He ran up and joined Hunter, and they went together to the knoll some hundred and twenty yards away, from which they expected to get a view of the southern shore and perhaps of the men from whom the cries came. They were careful to keep under cover, and, on arriving at the knoll, lay flat on the ground. As they had hoped, they could now see a large portion of the lake which had previously been hidden from them, and caught glimpses, on the western side, of the bridle-track here and there among the trees. At intervals it disappeared behind slight hillocks or denser stretches of the plantation.
