“Professor!” cried Bob. “Jerry’s hurt!”

The scientist had disappeared on the top of the mound. Hardly had the echoes of Bob’s voice died away than from the forest surrounding the mound there emerged a band of ugly-looking negroes. They started to run toward the boys just as Mr. Snodgrass, hearing the call of distress, began to descend the stone steps.

THE SEMINOLE CHIEF

Jerry’s faintness however, was of short duration. When Ned ceased trying to extract the stone the terrible pain subsided, for the time being, and Jerry opened his eyes.

“Let the professor take it out,” he murmured. “He can do it.” Then he caught sight of the advancing negroes. “Where’s the gun?” he asked.

Bob had secured it after Jerry’s fall, and at this, he raised it in readiness, though he did not point it at the black men. At the sight of it, however, they stopped. One of them, who seemed to be a leader, raised his hand and called out:

“What yo’ uns want heah?”

“We came to look at this curious mound,” replied the professor, speaking in conciliatory tones. “We were looking for relics. Why? What has happened?” he exclaimed as he saw the blood on Jerry’s foot. Evidently he had not heard Bob’s cry.
