"By all means; orderly, instruct the workers to follow the direction of the young men," said the captain.
CHAPTER IV
A LESSON IN OBSERVATION
The strenuous work was completed before night covered the scene. The flying machines had acted as a screen, and the guns, now in position, were effectually covered from the eyes of a prying foe. As they were about to leave the captain said:
"For the present you may find room in the vans, but tomorrow the regular quarters will be prepared near the guns."
The steaming hot supper, which was brought up in the kitchen vans, was relished as never before. After the meal they sat around and talked over the incidents of the day, and learned each other's histories, for there is a comradeship in the field that obtains nowhere else in any other occupation.
"And so you have been flying?" said the sergeant. "That has always had a fascination for me, but, strange as it may seem, I have never yet been up in the air, although I have had many opportunities. I have often wondered how things look from a height of two kilometers."
"Well, the first time I went up I couldn't distinguish a thing," said Ralph. "I could tell what trees were, and could make out rivers, and houses, of course, but outside of that everything else looked like a blurred picture."
"Couldn't you make out people walking, or troops marching, and the like?" asked one of the men.
