like an army closing in upon the enemy, leaping over bushes or crawling

For a moment Bumper was startled. He had a vision of being attacked on all

his anxiety was of short duration. The rabbits reached the side of the
rock, and disappeared as if by magic.

Then Bumper understood. They had made a simultaneous rush for their
burrow, knowing that this was the safest place for them. When the last

entrance. There was certainly an entrance to the burrow, or his cousins
couldn't have disappeared so quickly.

Bumper searched on every side for over an hour, but so artfully concealed
was the entrance to the burrow that he was unsuccessful. There was no
noise under the rock--nothing to indicate that there were rabbits there.

Discouraged and down-hearted, he was nearly ready to give up when he
