The tunnel in question was a very deep burrow under some mile of hill that rose steeply above it, and its completion--or so close an approach to completion that it could be used--had been the great triumph of speed in the construction of the line. He found that the work remaining to be done was easily compassable within a week or two, if sufficient numbers of men could be brought to the spot, while there was also at the Wyfold end of the tunnel another unfinished piece of less extent, if anything, than this. The report of the engineer also put matters in rather a less serious light: the great beams and timber which supported the wooden arch over which the bricks had to be laid were at present absolutely secure; it would take weeks of rain before danger was even threatened, but would it not be well, if possible, to finish so small a job at once, and have it off their minds? Bilton was decidedly of this opinion, and gave orders that steps should be taken to get outside labour without delay. This concluded his morning's work. He looked at his watch; it was later than he had known, and to walk back a mile to Frampton, where he could get a trap, and then drive over the huge ridge of the tunnel down into Wyfold, might mean missing the train, which would stop for him there, but would assuredly not wait if he was not on the platform. But the engineer had an easy solution. Why not walk through the tunnel, which would take very little longer than going back to Frampton? He would thus find himself within a mile of the Wyfold Station? He could get there in very little over half an hour, going briskly, and would easily be in time to step into the stopped express. No train was due on either line for the next half-hour; in fact, the next train that would pass would be the Southampton to Liverpool express, in which at the moment he would himself be travelling. The engineer would provide him with a lantern, which he could leave at the signal-box at the other end of the tunnel.
