For a flash Nat felt like giving way to the wild, unreasoning panic that sometimes overwhelms those who suddenly discover they are hopelessly lost. His impulse was to dash into the wood and set off running in what he thought must be the right direction. But he checked himself by an effort of will, and forced his mind to accept the situation as calmly as possible.
"How foolish I was not to mark the trees as I came along!" he thought.
If only he had done that it would have been a simple matter to find his way back. A sudden idea flashed into his mind, and drawing out his watch the boy pointed the hour hand at the sun, which was, luckily, in full sight. He knew that a point between the hour hand thus directed, and noon, would indicate the north and south line.
As Nat had begun to think, this test showed him that he had been almost completely turned about, and had probably come miles in the wrong direction.
The east lay off to his right. Nat faced about, and was starting pluckily off in that direction when a sudden commotion in a clump of chaparral below attracted his attention. A flock of blue jays flew up, screaming and scolding hoarsely in their harsh notes.
Nat was woodsman enough to know that the blue jay is the watch-dog of the forests. Their harsh cries betoken the coming of anything for half a mile or more. Sometimes, however, they do not scream out their warning till whatever alarms them is quite close.
As the birds, uttering their grating notes, flew upward from the clump in the chaparral, Nat paused. So still did he keep that he could distinctly hear the pounding of his heart in the silence. But presently another sound became audible.
The trampling of horses coming in his direction!
