"The crescent earth!" she breathed, in wonder.
"The crescent earth!" echoed Bennie. "How marvelous—like the new moon! I suppose we should call it 'the new earth.' See, there is the whole Atlantic coast line from Cape Horn to Hudson Bay—Florida and the Gulf of Mexico, Greenland and the Arctic ice-cap! Look at the cloud-banks over the Atlantic Ocean and along the west coast of South America. Quick—get your camera and put in a telephoto lens!"
The camera was still hanging by its strap from Rhoda's shoulder, and it took but a moment to exchange the lenses. Then she threw a puzzled glance at her comrade.
"How shall I do it? I don't understand," she hesitated.
"You will have to take the picture through the deadlight," he answered.
"But how long an exposure shall I make?" she inquired.
"Oh—a tenth of a second," he suggested, "or a fifth, perhaps."
Rhoda was having a hard time to preserve her equilibrium and handle the camera.
"Oh dear," she complained; "I can't keep still. This weighing nothing is very awkward—you slip around so."
With Bennie's assistance, however, she managed to hold the lens firmly against the deadlight.
