At Gournay they told him that some American engineers were repairing the bridge at Saumont, which had been damaged by floods, but that he might gain the north road to the coast by going back as far as Songeons and following the path along the upper Therain River, which would take him to Aumale, and bring him into the Neufchatel road. He lost perhaps two hours in doing this, partly by reason of the extra distance and partly by reason of the muddy, and in some places submerged, path along the Therain. The stream, ordinarily hardly more than a creek, was so swollen that he had to run his machine through a veritable swamp in places, and anything approaching speed was out of the question. So difficult was his progress, what with running off the flooded road and into the stream bed, and also from his wheels sticking in the mud, that he began to fear that he was losing too much time in this discouraging business. But there was nothing to do but go forward, and he struggled on, sometimes wheeling his machine, sometimes riding it, until at last it sank almost wheel deep in muddy water and he had to lose another half hour in cleaning out his carbureter. He feared that it might give trouble even then, but the machine labored along when the mud was not too deep, and at last, after almost superhuman effort, he and _Uncle Sam_ emerged, dirty and dripping, out of a region where he could almost have made as good progress with a boat, into Aumale, where he stopped long enough to clean the grit out of his engine parts. It was now nearly four o'clock in the morning, and his instructions were to reach Dieppe not later than five. He knew, from his own experience, that transports always discharge their thronging human cargoes early in the morning, and that every minute after five o'clock would increase the likelihood of his finding the soldiers already gone ashore and separated for the journeys to their various destinations. To reach Dieppe after the departure of the soldiers was simply unthinkable to Tom. Whatever excuse there might have been to the authorities for his failure, that also he could not allow to enter his thoughts. He had been trusted to do something and he was going to do it. Perhaps it was this dogged resolve which deterred him from doing something which he had thought of doing; that is, acquainting the authorities at Aumale with his plight and letting them wire on to Dieppe. Surely the wires between Aumale and the coast must be working, but suppose----
