By their united efforts the wrecked seaplane was toppled over into the canal. The sudden contact of the cold water with the hot cylinders would, they knew, fracture the castings and make the motor useless until complicated and costly repairs had been executed--even if the Germans succeeded in fishing the debris out of the mud at the bottom of the canal. "Now we'll make tracks," decided Fuller. "Wonder there aren't soldiers on the spot already." "Yes, we'll make tracks," agreed Barcroft, "but not the ones you are keen on leaving behind." He pointed to the muddy tow-path and to the comparatively dry ground on the other side of the row of poplars. "We'll walk backwards as far as the field," he continued. "The Boches are bound to examine the footprints. If they see that they lead in the direction of the canal it may baffle 'em a bit. We must look sharp. I see the water falling an inch or so." "But the canal isn't tidal," remarked Kirkwood. "I agree," assented Billy. "The slight fall tells me that the nearest lock has been opened. That means a barge is on its way, and, much as I regret missing the sight of a Hun cargo boat bumping on the wreckage of the old bus, prudence demands that we sheer off." Having walked backwards until they reached hard ground the trio set off cautiously. The country consisted of tilled fields--the work of impressed Belgians, forced by their taskmasters to cultivate the ground to provide foodstuffs for the Huns. The absence of hedges gave the land an unfamiliar appearance as far as the three British officers were concerned. What was of more pressing significance there was a lack of efficient cover, the only means of securing shelter being by keeping close to the trees that bounded the fields. "There's a spinny of sorts in there," said Kirkwood, pointing to a circular cluster of bushes. "I vote we make for that and repair damages." "And find ourselves surrounded by dozens of Boches," added Fuller. "Naturally, once they found the wreckage of our machine they would search the nearest cover. We must make for those woods What say you, old bird?" "Yes, and remain till nightfall," added Barcroft. The wood was nearly a mile away, and presented an expanse of leafless trees extending nearly twice that distance. The depth of the wood the fugitives had no means of discovering. For the last four hundred yards the three officers crawled and crouched, for the ground was as flat and unbroken as a table-top. Away on the right could be discerned a red-tiled farmhouse, close to it a roofless barn, with the two charred gables standing up clearly against the sky. Further away was a village of considerable size, but in all directions there were no signs of human beings or of cattle.
