The servant reappeared, carrying in his arms a small dog. The doctor stepped to the control board of his strange machine.
"All right, George," he said.
The servant had evidently worked with the old man enough to know what was expected of him. He stepped close to the floor disk and waited. The dog whined softly, sensing that all was not exactly right.
The old scientist slowly shoved the lever toward the right, and as he did so a faint hum filled the room, rising to a stupendous roar as he advanced the lever. From both floor disk and upper disk leaped strange cones of blue light, which met midway to form an hour-glass shape of brilliance.
The light did not waver or sparkle. It did not glow. It seemed hard and brittle, like straight bars of force. The newspaperman, gazing with awe upon it, felt that terrific force was there. What had the old man said? Warp a third-dimensional being into another dimension! That would take force!
As he watched, petrified by the spectacle, the servant stepped forward and, with a flip, tossed the little dog into the blue light. The animal could be discerned for a moment through the light and then it disappeared.
"Look in the globe!" shouted the old man; and Henry jerked his eyes from the column of light to the half-globe atop the machine.
He gasped. In the globe, deep within its milky center, glowed a picture that made his brain reel as he looked upon it. It was a scene such as no man could have imagined unaided. It was a horribly distorted projection of an eccentric landscape, a landscape hardly analogous to anything on Earth.
"That's the fourth dimension, sir," said the servant.
