In a few hours he had a complete laboratory set up around the meteorite. He worked feverishly in the hot sunshine, reading the various instruments he had set up, and arranging more. He contrived to keep the stone cold by packing it in a box of dry ice.

The mechanics stopped for dinner, and I tried to get him to take time to eat.

"No, Hammond," he said. "This is something big! We were talking about Einstein. This rock seems energized with a new kind of force: all meteors are probably the same way, when they first plunge out of space. I think this will be to relativity what the falling apple is to gravity. This is a big thing."

He looked up at me, brown eyes flashing.

"This is my chance to make a name, Hammond. If I do something big enough—Virginia might reconsider her opinion."

Charlie worked steadily through the long hot afternoon. I spent most of the time helping him, or gazing in fascination at the curious haze of luminous blue mist that clung like a sphere of azure fog about the meteoric stone. I did not completely understand what he did; the reader who wants the details may consult the monograph he is preparing for the scientific press.

He had the men string up a line from our direct current generator in the shops, to supply power for his electrical instruments. He mounted a powerful electromagnet just below the meteorite, and set up an X-ray tube to bombard it with rays.

Light came, and the fire of the white sun faded from the sky. In the darkness, the curious haze about the stone became luminescent, distinct, a dim, motionless sphere of blue light. I fancied that I saw grotesque shapes flashing through it. A ball of blue fire, shimmering and ghost-like, shrouded the instruments.

Charlie's induction coil buzzed wickedly, with purple fire playing about the terminals. The X-ray tube flickered with a greenish glow. He manipulated the rheostat that controlled the current through the electromagnet, and continued to read his instruments.

"Look at that!" he cried.

The bluish haze about the stone grew brighter; it became a ball of sapphire flame, five feet thick, bright and motionless. A great sphere of shimmering azure fire! Wisps of pale, sparkling bluish mist ringed it. The stone in its box, the X-ray bulb and other apparatus were hidden. The end of the table stuck oddly from the ball of light.

I heard Charlie move a switch. The hum of the coils changed a note.

The ball of blue fire vanished abruptly. It became a hole, a window in space!
