Yet he was fain to pause and wipe the sweat from his face when he found himself safely in the disused track, and knew by the silence that he was beyond the line of sentries. A rough road lay before him, but he traversed it rapidly, being anxious to get the worst of it over before the lingering light deserted the peaks. As he stood on the summit he was startled at the lurid look of the vast masses of cloud which, rolling up to his very feet, obscured all view beyond. They were in for a big storm, he thought, as he hurried down the slopes at a break-neck pace; with all his haste barely reaching the shanty in time, for a low growl of thunder greeted his arrival, and as he pulled the latch a faint gleam of light showed him the empty room. He called loudly; darkness and silence: again, as he struck a match; light, but still silence. Quick as thought, Dick was at the signaller, and the electric bell rang out incongruously. _Tink-a-tink-a-tink_ was echoed from the eastward. But westward? He waited breathlessly, while not a sound returned to him. Communication was broken; the wires had possibly been cut, and Dick stood up with a curiously personal sense of injury. His wires tampered with out of sheer mischief! Yet stay! Might it not be something more? Where the devil had the _bâbu_ hidden himself? After fruitless search an idea struck him, and he signalled eastward once more. "Repeat your last message, giving time at which sent." With ears attuned to tragedy Dick awaited the reply. "6 P.M. To north side. 'Will send cocoa-nut oil and curry stuff by next mail.'" The echo of Dick's laughter, as he realised that but an hour or so before the _bâbu_ had been putting the telegraph to commissariat uses, was the last human sound the shanty was to hear for many a long day. For the next moment's thought roused a sudden fear. The _bâbu_ had doubtless gone over the Pass with the troops for the sake of company; that was natural enough, but if he was still in the north shanty awaiting Dick's return, why had he not answered the signal sent westward? It could not be due to any break in the wire, unless the damage had been done after dark, for he had been able to telegraph eastward not so long ago. Was there more afoot than mere mischief? It was not a night for a dog to be out in, and as Dick stood at the door he could see nothing but masses of cloud hurrying past, softly, silently. Then suddenly a shudder of light zig-zagged hither and thither, revealing only more cloud pierced by a few pinnacles of rock.
