What is Rainsford's strategy? Where does Rainsford hide?

Rainsford's initial strategy was to give the General a trail to follow, hide, and get some rest.

I'll give him a trail to follow," muttered Rainsford, and he struck off from the rude path he had been following into the trackless wilderness. He executed a series of intricate loops; he doubled on his trail again, and again, recalling all the lore of the fox hunt, and all the dodges of the fox. Night found him leg-weary, with hands and face lashed by the branches, on a thickly wooded ridge. He knew it would be insane to blunder on through the dark, even if he had the strength. His need for rest was imperative and he thought, "I have played the fox, now I must play the cat of the fable."

Rainsford hid in a tree.

A big tree with a thick trunk and outspread branches was near by, and, taking care to leave not the slightest mark, he climbed up into the crotch, and, stretching out on one of the broad limbs, after a fashion, rested. Rest brought him new confidence and almost a feeling of security. Even so zealous a hunter as General Zaroff could not trace him there, he told himself; only the devil himself could follow that complicated trail through the jungle after dark. But perhaps the general was a devil--

Zaroff....... began to hunt.

"He made his way along with his eyes fixed in utmost concentration on the ground before him. He paused, almost beneath the tree, dropped to his knees and studied the ground. Rainsford's impulse was to hurl himself down like a panther, but he saw that the general's right hand held something metallic--a small automatic pistol.
