"I guess he's all in," he called to Tom.
"Bless my horseradish! And so our friend seems to be," commented Mr. Damon. "Have you anything with which to revive him, Tom?"
"Yes. Some ammonia. See if you can find a little water."
"I have some in my flask."
Tom mixed a dose of the spirits which he carried with him, and this, forced between the pallid lips of the scientist, revived him.
"What happened?" he asked faintly as he opened his eyes. "Oh, yes, I remember," he added slowly. "The boa——"
"Don't try to talk," urged Tom. "You're all right. The snake is dead, or dying. Are you much hurt?"
Professor Bumper appeared to be considering. He moved first one limb, then another. He seemed to have the power over all his muscles.
"I see how it happened," he said, as he sat up, after taking a little more of the ammonia. "I was following the iguana, and when the big lizard came to a stop, in a little hollow place in the ground, at the foot of those two trees, I leaned over to slip a noose of rope about its neck. Then I felt myself caught, as if in the hands of a giant, and bound fast between the two trees."
"It was the big boa that whipped itself around you, as you leaned over," explained Tom, as Ned came up to announce that the snake was no longer dangerous. "But when it coiled around you it also coiled around the two trees, you, fortunately slipping between them. Had it not been that their trunks took off some of the pressure of the coils you wouldn't have lasted a minute."
