The lieutenant and the doctor had been gazing at the peak; it fascinated them, like it fascinated the men, and Stub. That night they talked together until late, planning for to-morrow. The lieutenant had decided to climb the mountain.

He sent for Sergeant Meek. The sergeant stood before him and saluted.

“I intend to take Doctor Robinson and two of the men, and this boy, to-morrow, and set out for the big mountain,” the lieutenant said. “The camp will be left in your charge.”

“Yes, sir,” replied Sergeant Meek.

“These reports of the journey to date I also leave, with my personal baggage. The mountain is only a short day’s march, but I have to consider that we may be cut off or meet with other accident. To-morrow morning I will lay out a stockade, here, for the protection of your party. You are to wait here one week, with due caution against surprises by the savages and the Spanish. Admit nobody except your own command into the stockade. If we do not return or you do not hear from us within the seven days, you are to take my papers and such baggage as may be necessary, and march down river by the safest direct course for the nearest American settlement or military post, as may be. At the American frontier you will leave your men under instructions to report at St. Louis, and you will press ahead at best speed and deliver my papers to General Wilkinson, the head of the Army, wherever he may be. In event of your disability, you will entrust the papers to Corporal Jackson—acquainting him in advance with what is expected of him. In the meantime, here or on the march, keep your men alert and together, and do not forget that our Country depends upon our performing our duty without regard to our own interests.”

“Yes, sir,” replied the sergeant. He gulped—the ragged, weather-worn soldier. “Excuse me, sir—’tis only a day’s march yonder, you say? You’ll be coming back, sir?”

“If within human possibility, sergeant. But I must climb that mountain to its highest point, in order to make certain of our position and ascertain the trend of the various streams. We are near the sources of the Arkansaw, as is evident. Our instructions are to find the heads of the Arkansaw and the Red River, on our way to the Comanches.”

“Yes, sir,” replied the sergeant.

“That is all. Good-night.”

“Good-night, sir. I make bold to wish you good luck, sir. I wish I might be going with you, sir.”
