"Yes," said Jim. "I believe you've hit it."
"Well, now you know I don't like Davies and you have found out why he's here, you ought to be satisfied."
"But I haven't found out why he's here; that's the trouble," Jim rejoined, and was silent for a few moments. "However, perhaps you have put me on the track," he went on. "I was something of a fool when I wanted to leave you behind. You have helped us all the time. But you haven't enough wood for morning; I'll go and chop some."
He went off and Carrie sat quietly by the fire. There was faint amusement in her eyes, but they were soft. By and by the light began to fade and rousing herself she made some bannocks for breakfast. When Davies came back with a string of fish she had vanished and the light that had burned in her tent was out.
Next morning Davies left the camp and Jim sent three or four men to build a wall to protect the line, while he and some others put up the posts. Their progress was slow, because it was necessary to make the wall strong and Jim was occupied for a week before he was satisfied with the length he had built. He thought it ought to stand, but felt disturbed when he calculated what the extra work had cost. It was, however, a comfort to know he had covered the worst ground, and soon after supper one evening he went off in better spirits than usual to a little bark shelter he had built for himself.
He was tired and soon went to sleep, but after some hours awoke. He supposed he was rather highly strung after working hard, because he did not feel sleepy, and lifting his head he looked about. The end of the shelter was open and the pines outside rose like vague black spires, their tapered tops cutting against the sky. Although there was no moon, the first row of trunks stood out against the deeper gloom behind. One could smell the resin and the warm soil, damped by heavy dew. All was very quiet, but after a few moments Jim began to listen. He had lived in the wilds, his senses were keen, and sometimes he received unconsciously impressions of minute noises. Although the stillness was only broken by the turmoil of the river far down in the valley, he imagined it was not for nothing he had wakened.
Then he raised himself on his elbow as he heard another sound. It was very faint, but somehow definite, although he could not tell what it was. A few moments afterwards, he knew; a stone was rolling down hill and disturbing others as it went. Then there was a sharp crash and a rattle that began to swell into a roar, and Jim, leaping up, ran along the hill. The bank he had built had broken and the stones behind it were plunging down.
When he reached the line he struck his foot against a rock and stumbled. The ground was rough, the night was dark, but it was unthinkable that he should stop. He clenched his hands and ran, although he did not know what he could do. When trouble threatened he must be on the spot. In the meantime, the noise got louder. He heard great blocks strike the ledges down the slope and smash; trees broke and branches crashed, while behind the detached shocks there was a steady, dull roar of small gravel grinding across the rocks and tearing up the brush. The wall had obviously gone and its collapse had started a slide that might not stop until all the stones above the line had run down. If so, they might plane off a wide belt of hillside and carry the soil and broken timber into the valley. Then Jim would be forced to dig out another line.
He gasped as he labored on, but the uproar had begun to die away when he reached an opening in the thin forest. At sunset, straggling trees had dotted the slope, but they had gone and, so far as he could see, nothing but a few stumps broke the smooth surface of the hill. The wall had vanished with the line it was meant to protect. Now and then a big stone rolled by, but Jim did not think about the risk. He must try to find out if much of the surface was left and if there was rock beneath.
When he left the end of the line, small stones slipped away from his feet and plunged down into the dark. This was ominous, since gravel is awkward stuff to work among when it does not lie at rest. However, with plenty of stakes and some underpinning, he might be able to build up a new bank. By and by his foot struck something sharp and he looked up. He had kicked the edge of a large, ragged stone, and an indistinct, broken mass ran up the hill. The blocks had obviously come down from the bottom of the crags and, since they had gone no farther, the pitch was easy enough for them to lie. This would enable him to clear a line across the mass and build a fresh bank.
