He could not see any of them.
They were certainly beyond range of his bow, and it was difficult to make them seek the den without their rushing into it.

But he was equal to the occasion.

He raised one hand and made the query sign, and watching Rolf he got answer, "All well; they are there." (A level sweep of the flat hand and a finger pointing steadily.) Then he waited a few seconds and made exactly the same sign, getting the same answer.
He knew that the movement of the distant man would catch the eye of the old woodchuck; she would sit up high to see what it was, and when it came a second time she would, without being exactly alarmed, move toward the den and call the young ones to follow.
The hunter had not long to wait.

He heard her shrill, warning whistle, then the big chuck trotted and waddled into sight, stopping occasionally to nibble or look around.

Close behind her were the two fat cubs.
Arrived near the den their confidence was restored, and again they began to feed, the young ones close to the den.
