That night the trap remained unsprung; next morning as Rolf went at silent dawn to bring water from the lake, he noticed a long, dark line that proved to be ducks.

As he sat gazing he heard a sound in the tree beyond the cabin.

It was like the scratching of a squirrel climbing about.

Then he saw the creature, a large, dark squirrel, it seemed.

It darted up this tree and down that, over logs and under brush, with the lightning speed of a lightning squirrel, and from time to time it stopped still as a bump while it gazed at some far and suspicious object.
