moving, of whispering to ask the Boy what it meant, when the latter, divining his unrest, stealthily laid a restraining hand upon his arm. He guessed that the beavers were on the alert, hiding, and watching to see if any of their enemies should be attracted by the noise.
Not five seconds later, however, he forgot his aches. Appearing with uncanny and inexplicable suddenness, there was the big pioneer again, sitting up by the edge of the canal. As before, he sat absolutely motionless for a minute or two, sniffing and listening. Then, satisfied once more that all was well, he moved lazily up the slope to examine the tree; and in half a minute all were at work again, except that there was no more tree-felling. The great business of the hour was cutting brush.
For some time longer the watchers lay motionless, noting every detail of the work, till at last the Boy began to think it was time to release Jabe from his long and severe restraint and break up the beaver “chopping-bee.” Before he had quite made up his mind, however, his eyes chanced to wander a little way up the slope, and to rest, without any conscious purpose, on a short gray bit of log. Presently he began to wonder what a piece of log so short and thick–not much more than three feet long–would be doing there. No beavers would waste time cutting up a twelve-inch log into lengths like that. And there had been no lumberman in the neighbourhood. Then, in a flash, his eyes cleared themselves of their illusion. The log had moved, ever so slightly. It was no longer a log, but a big gray lynx, creeping slowly, inexorably, down upon the unsuspecting people of the pond.
For perhaps ten seconds the Boy stared in uncertainty. Then he saw the lynx gather his muscles for the final, fatal rush. Without a whisper or a warning to the astonished Jabe, he whipped up his rifle, and fired.
The sharp report seemed to shatter the whole scene. Its echoes were mixed with the scattering of the horrified beavers as they rushed for the water–with the short screech of the lynx, as it bounced into the air and fell back on its side, dead–with an exclamation of astonishment from Jabe–and with a crashing of branches just behind the thicket. The Boy looked around, triumphant–to see that Jabe’s exclamation was not at all the result of his clever shot. The woodsman was on his hands and knees, his back turned, and staring at the form of a big black bear as it lumbered off in a panic through the bushes. Like the unfortunate lynx, the bear had been stalking the beavers on his own account, and had almost stepped upon the silent watchers in the thicket.
CHAPTER V
Dam Repairing and Dam Building
AS the Boy trudged triumphantly back toward camp, over the crest of the moon-bright ridge, he carried the limp, furry body of the lynx slung by its hind legs over his shoulder. He felt that his prestige had gone up incalculably in the woodsman’s eyes. The woodsman was silent, however, as silent as the wilderness, till they descended the other slope and came in sight of the little solitary camp. Then he said: “That was a mighty slick shot of yourn, d’ye know it? Ye’re quicker’n chain lightnin’, an’ dead on!”
“Just luck, Jabe!” replied the Boy carelessly, trying to seem properly modest.
This different suggestion Jabe did not take the trouble to controvert. He knew the Boy did not mean it.
“But I thought as how ye wouldn’t kill anything?” he went on, teasingly.
“Had to!” retorted the Boy. “That was self-defence! Those beavers are my beavers. An’ I’ve always wanted a real good excuse for getting a good lynx skin, anyway!”
“I don’t blame ye a mite fer standin’ by them beaver!” continued Jabe. “They’re jest all right! It was better’n any circus; an’ I don’t know when I’ve enjoyed myself more.”
“Then the least you can do, Jabe, is promise not to trap any more beavers!” said the Boy quickly.
“Wa’al,” answered Jabe, as they entered camp and began spreading their blankets, “leastwise I’ll do my best to see that no harm comes to them beaver, nor to the pond.”
Next morning, as the woodsman was starting out for the day’s cruise, the Boy said to him:
“If you’re game for another night’s watching, Jabe, I’ll show you something altogether different up at the pond to-night.”
“Try me!” responded the woodsman.
“You’ll have to be back earlier than usual, then,” said the Boy. “We’ll have to get hidden earlier, and in a new place.”
“I’ll come back along a couple of hours afore sundown, then,” answered Jabe, swinging off on his long, mooselike stride. It was contrary to his backwoods etiquette to ask what was in store for him; but his curiosity was excited, and kept him company through the solitude all day.
When Jabe was gone, the Boy went straight up-stream to the dam, taking no special care to hide his coming. His plan was one in regard to which he felt some guilty qualms. But he consoled himself with the thought that whatever harm he might be doing to the little citizens of the pond would be more than compensated by the protection he was giving them. He was going to make a break in the dam, for the sake of seeing just how the beavers would mend it.
On reaching the dam, however, it occurred to him that if he made the break now the beavers might regard the matter as too urgent to be left till nightfall. They might steal a march on him by mending the damage little by little, surreptitiously, through the day. He had no way of knowing just how they would take so serious a danger as a break in their dam. He decided, therefore, to postpone his purpose till the afternoon, so that the beavers would not come to the rescue too early. In the meantime, he would explore the stream above the pond, and see if there were other communities to study.
Skirting the hither side of the pond to near its head, he crossed the little meadow and the canal, and reached the brook again about fifty yards beyond. Here he found it flowing swift and narrow, over a rocky bottom, between high banks; and this was its character for nearly half a mile, as he judged. Then, emerging once more upon lower ground, he came upon a small dam. This structure was not much over eighteen inches in height, and the pond above it, small and shallow, showed no signs of being occupied. There was no beaver house to be seen, either in the water or on shore; and the water did not seem to be anywhere more than a foot and a half in depth. As he puzzled over this–for he did not think the beavers were likely to build a dam for nothing–he observed a second and much larger dam far away across the head of the pond.
Hastening to investigate this upper dam, he found it fully three feet high, and very massive. Above it was a narrow but deep pond, between comparatively steep shores; and along these shores he counted three low-roofed houses. Out in the middle of the pond there was not one dwelling; and he came presently to the conclusion that here, between the narrow banks, the current would be heavy in time of freshet. The lower dam, pretty obviously, was intended to reinforce the upper, by backing a foot and a half of water against it and taking off just that much of the pressure. He decided that the reason for locating the three houses along the shore was that the steep bank afforded special facilities for shore burrows.
The explorer’s fever being now hot upon him, the Boy could not stay to examine this pond minutely. He pressed on up-stream with breathless eagerness, thrilling with expectation of what the next turn might reveal. As a matter of fact, the next turn revealed nothing–nor the next, nor yet the next. But as the stream was full of turns in this portion of its course, that was not greatly discouraging.
About a quarter of a mile, however, above the head of the narrow pond, the ardent explorer came upon a level of sparse alder swamp. Here he found the stream just beginning to spread over its low banks. The cause of this spreading was a partial obstruction in mid-channel–what looked, at first glance, like an accidental accumulation of brush and stones and mud. A second look, however, and his heart jumped with excitement and delight. Here was the beginning of a new pond, here were the foundations of a new dam. He would be able to see what few indeed of the students of the wilderness had had the opportunity to watch–the actual process by which these wilderness engineers achieved their great work.
All about the place the straightest and brushiest alders had been cut down, those usually selected being at least ten or twelve feet in height. Many of them were still lying where they fell; but a
