CHAPTER THREE.
Of all the living creatures in this sleeping valley, Thor was the busiest.
He was a bear with individuality, you might say.

Like some people, he went to bed very early; he began to get sleepy in October, and turned in for his long nap in November.

He slept until April, and usually was a week or ten days behind other bears in waking.

He was a sound sleeper, and when awake he was very wide awake.

During April and May he permitted himself to doze considerably in the warmth of sunny rocks, but from the beginning of June until the middle of September he closed his eyes in real sleep just about four hours out of every twelve.
He was very busy as Langdon began his cautious climb up the gully.
