oting that would allow him to reach the watchful invader.
But between the solid wall of the dam and the bank there was a tangled
framework through which the water rushed with some violence. Three times
Kazan fought to work his way through that tangle, and three times his
efforts ended in sudden plunges into the water. All this time Broken
Tooth did not move. When at last Kazan gave up the attack the old
engineer slipped over the edge of the dam and disappeared under the
water. He had learned that Kazan, like the lynx, could not fight water
and he spread the news among the members of his colony.

Gray Wolf and Kazan returned to the windfall and lay down in the warm
sun. Half an hour later Broken Tooth drew himself out on the opposite
shore of the pond. He was followed by other beavers. Across the water
they resumed their work as if nothing had happened. The tree-cutters
returned to their trees. Half a dozen worked in the water, carrying
loads of cement and twigs. The middle of the pond was their dead-line.
Across this not one of them passed. A dozen times during the hour that
followed one of the beavers swam up to the dead-line, and rested there,
looking at the shining little bodies of the babies that Kazan had
killed. Perhaps it was the mother, and perhaps some finer instinct
unknown to Kazan told this to Gray Wolf. For Gray Wolf went down twice
to sniff at the dead bodies, and each time--without seeing--she went
when the mother beaver had come to the dead-line.

The first fierce animus had worn itself from Kazan's blood, and he now
watched the beavers closely. He had learned that they were not fighters.
They were many to one and yet they ran from him like a lot of rabbits.
Broken Tooth had not even struck at him, and slowly it grew upon him
that these invading creatures that used both the water and land would
have to be hunted as he stalked the rabbit and the partridge. Early in
the afternoon he slipped off into the bush, followed by Gray Wolf. He
had often begun the stalking of a rabbit by moving _away_ from it and he
employed this wolf trick now with the beavers. Beyond the windfall he
turned and began trotting up the creek, with the wind. For a quarter of
a mile the creek was deeper than it had ever been. One of their old
fording places was completely submerged, and at last Kazan plunged in
and swam across, leaving Gray Wolf to wait for him on the windfall side
of the stream.

Alone he made his way quickly in the
