Slowly at first, but gradually gaining momentum, it soared away across the wastes, and soon was lost to sight.
There was a moment after that when the room was dark, while horizontal streaks of light chased each other from bottom to top across the screen, and disappeared into the darkness from which they had come.
Another picture followed, taken from the same viewpoint as the last.
“Here she comes!” cried Edestone, seeming to forget for the moment where he was, as a small speck which represented the approaching airship disclosed itself. “This time in the upper right-hand corner of the picture. See! I am on board, and I am driving her at one hundred and ten miles.” And he followed with his pointer the swift course of the vessel, as it shot down the screen like a great comet, leaving a long tail of smoke behind it. To the overwrought nerves of the audience, the buzz and splutter of the moving-picture machine seemed to increase in volume, and thus lend a semblance of reality to the monster as it swept nearer and nearer.
Straight for the camera it was headed, grim, threatening, irresistible, as if it were preparing to rush out of the screen and destroy Buckingham Palace. The spectators with difficulty kept their seats, and when the formidable thing dashed by and disappeared at the side of the picture, they settled back in their chairs with an unmistakable sigh of relief.
It appeared again, after making a great circle, returning slowly now, and dropping lightly as a feather to the cradle, where it remained perfectly still, while the black smoke enveloped it in a veil of mystery.
The machine in the cabinet stopped, and some one was heard to say in a loud whisper, “Lights!” Admiral Brown was the first of the assembly to recover. He sprang to his feet and like a wounded old lion at bay stood glaring at Edestone. His rugged weather-beaten face convulsed with suppressed rage, which but for the presence of the King would have exploded upon Edestone after the manner of the old-fashioned sea-dog that he was, but holding himself in check he said loudly and challengingly:
“If there is no objection I will ask the young man to repeat the last picture, and I would also like to inquire with what material the framework of this ship is covered, and what is the calibre of those large guns—if they are guns?”
“Will you please be so kind as to answer the Admiral’s questions, Mr. Edestone?” said the King.
“The material which I used through her entire length of 907 feet, both top and bottom, is Harveyized steel, six feet thick; and the largest gun is sixteen inches,” replied Edestone slowly, enjoying the look of blank amazement which spread over the Admiral’s face as he dropped back into his chair gasping and mopping his brow.
