“No, I’m not, boy.”

“Yes, you are. I order you to,” said Chris.

“Are you boss of this expedition?”

“You know I’m not.”

“Who is, then?”

“Don’t ask stupid questions,” said Chris irritably. “You know: father.”

“That’s right, and he gave the orders of the night—that I was to watch four hours before calling him, and I was to see that all was right in the camp. Now then, you’re kicking up a disturbance instead of going to sleep and resting yourself so that you may be useful in the morning.”

“But, Griggs—”

“You obey orders, sir,” said the man sternly. “Do you want to wreck the expedition by breaking rules?”

“No.”
