Urubu raised the gun butt to drive it down on Whitman’s head. Biff could see the savage look on Urubu’s face. Kamuka gripped Biff’s arm. The native boy’s voice was breathless:
“Somebody must help Mr. Whitman! Quick!”
CHAPTER V
The Spotted Terror
That jog from Kamuka’s hand gave Biff a sudden idea. Biff was holding the mirror so it threw a big spot of sunlight on the hut wall. The spot wavered when Kamuka jogged Biff’s arm, and Urubu was only a dozen feet from the corner of the hut.
Biff changed the mirror’s angle just a slight degree, spotting the light square in Urubu’s eyes. That reflected glint of the sun was enough. Urubu dropped back, flinging his arm upward to shield his vision. Mr. Whitman came to his feet and grappled for the shotgun. A few seconds later, Mr. Brewster had pitched into the struggle.
They disarmed Urubu, who stood by glaring sullenly. Biff and Kamuka approached the group, and Jacome, who had pulled the canoe on shore, came up behind them.
“You know what the name Urubu means, Biff?” Kamuka asked.
Biff shook his head.
“It means vulture,” the Indian boy said.
A chuckle came from Jacome. “A good name for Urubu. He is like one vulture!”
