It was about three o’clock when Bob held up his hand as Jack was talking.
“Listen.”
“She’s coming, sure as guns.”
Faintly they could hear the distant purring of a motor. Bob parted the bushes and looked out “Can’t see anything yet,” he announced a moment later. “But Pierre has just touched a match to a pile of brush and it’s sending up a big cloud of smoke. Must be a signal for him either to land or not to.” The sound of the approaching motor was rapidly growing louder and soon Jack, who was at the peep hole, announced that he could see it.
“And it looks like it was a whopper.”
“Sounds like a Liberty motor.”
“That’s what it is all right,” Jack agreed. “And she’s making some time, too.”
In a short time they could see the machine without making use of the peep hole, as it circled about far up in the sky.
“He’s coming down and he’s planning to hit the ground right out in front of us.”
“That’s so,” Bob agreed. “Hope he don’t happen to glance down and see us,” he added somewhat anxiously.
