"Sure," said Fenwick, grinning broadly. "Sam Atkins said good afternoon to you. It would be polite if you answered him back."
The image of Sam Atkins was still before them. He, too, was grinning broadly. The grins infuriated Baker.
"Mr. Atkins," said Baker.
"Yes, Dr. Baker," said Sam Atkins.
"If you hear me, wave your hands. I will observe you through the field glasses."
"The field glasses won't be necessary."
Both the image before them, and the distant figure on the knoll were seen to wave arms and gyrate simultaneously. For good measure, Sam Atkins turned a cartwheel.
Baker seemed to have partly recovered. "There seems to be a very remarkable effect present here," he said cautiously.
"Dr. Baker," Jim Ellerbee spoke earnestly, "I know you're skeptical. You don't think the crystals do what I say they do. Even though you see it with your own eyes you doubt that it is happening. I will do anything possible to test this device to your satisfaction. Name the test that will dispel your doubts and we will perform it!"
"It's not entirely a question of demonstration, Mr. Ellerbee," said Baker. "There are the theoretical considerations as well. The mathematics you have submitted in support of your claim are not, to put it mildly, sound."
