DuQuesne started the Violet off in the direction of the solar system occupied by the warlike strangers, but he did not hurry. He and Loring practiced incessantly for days at the controls, darting here and there, putting on terrific acceleration until the indicators showed a velocity of hundreds of thousand of miles per second, then reversing the acceleration until the velocity was zero. They studied the controls and alarm system until each knew perfectly every instrument, every tiny light, and the tone of each bell. They practiced with the rays, singly and in combination, with the visiplates, and with the many levers and dials, until each was so familiar with the complex installation that his handling of every control had become automatic. Not until then did DuQuesne give the word to start out in earnest toward their goal, at an unthinkable distance.
They had not been under way long when an alarm bell sounded its warning and a brilliant green light began flashing upon the board.
"Hm ... m," DuQuesne frowned as he reversed the bar. "Outside intra-atomic energy detector. Somebody's using power out here. Direction, about dead ahead—straight down. Let's see if we can see anything."
He swung number six, the telescopic visiplate, into connection. After what seemed to them a long time they saw a sudden sharp flash, apparently an immense distance ahead, and simultaneously three more alarm bells rang and three colored lights flashed briefly.
"Somebody got quite a jolt then. Three rays in action at once for three or four seconds," reported DuQuesne, as he applied still more negative acceleration.
"I'd like to know what this is all about!" he exclaimed after a time, as they saw a subdued glow, which lasted a minute or two. As the warning light was flashing more and more slowly and with diminishing intensity, the Violet was once more put upon her course. As she proceeded, however, the warnings of the liberation of intra-atomic energy grew stronger and stronger, and both men scanned their path intensely for a sight of the source of the disturbance, while their velocity was cut to only a few hundred miles an hour. Suddenly the indicator swerved and pointed behind them, showing that they had passed the object, whatever it was. DuQuesne instantly applied power and snapped on a small searchlight.
"If it's so small that we couldn't see it when we passed it, it's nothing to be afraid of. We'll be able to find it with a light."
After some search, they saw an object floating in space-apparently a vacuum suit!
"Shall one of us get in the airlock, or shall we bring it in with an attractor?" asked Loring.
