"Radio for warships, eh?" he muttered. A wireless transmitter was one of many modern innovations that the Virginia did not boast. She had been gathering copra and shell among the islands long before such things came into common use, though Dan had invested his modest savings in her only a year before.
"What would anyone want with warships on Davis Island?" The name roused a vague memory. "Davis Island?" he repeated, staring in concentration at the black sea. "Of course!" It came to him suddenly. A newspaper article that he had read five years before, at about the time he had abandoned college in the middle of his junior year, to follow the call of adventure.
The account had dealt with an eclipse of the sun, visible only from certain points on the Pacific. One Dr. Hunter, under the auspices of a Western university, had sailed with his instruments and assistants to Davis Island, to study the solar corona during the few precious moments when the shadow covered the sun, and to observe the displacement of certain stars as a test of Einstein's theory of relativity.
The reporter had interviewed the party at San Francisco, on the eve of sailing. There had been photographs of the chartered vessel, of Dr. Hunter and his instruments, and of his daughter, Helen, who acted as his secretary. She looked not at all like a scientist, Dan recalled. In fact, her face had seemed rather pretty, even in the blurred newspaper half-tone.
But the memory cast no light upon the present puzzle. In the rambling years that had led him to this spot upon the old Virginia, he had lost touch with the science that had interested him during his college days. He had heard nothing of the results of the Hunter expedition. But this island had been its destination.
e turned decisively to the man at the wheel. "Larsen, we'll stand well offshore till daylight," he said. "Then, unless we see something unusual, we can sail in and land a boat to—"
The sentence was never finished. Through the corner of his eye, Dan saw a ray of green light darting toward them from the island. A line of green fire seemed to reach out and strike him a physical blow. Green flame flared around him; and somehow he was hurled from the bridge, clear of the rail and into the sea.
His impression of the incident was very confused. He seemed to have struck the water with such force that his breath was knocked out. He struggled back to the surface, strangling, and coughing the bitter brine from his lungs. It was several minutes before he was comfortably treading water, and able to see what had happened.
