Instinctively Frank and Harry reached for their revolvers, as soon as they recovered their senses.

“The señors will not move if they value their lives;” said a voice in excellent English, which proceeded from an officer; evidently in charge of the force of men which had surprised them.

“What?” gasped the boys angrily.

“Because,” went on the soft-voiced officer, not noticing their indignant exclamation, “I shall then be under the painful necessity of shooting down the two Señors Chester without the formality of a court-martial.”

CHAPTER XXVI.

THE FLOWER OF FLAME.

Ben Stubbs and Billy had stood straining their eyes after the Golden Eagle, when the air-craft flew from Plateau Camp, for as long as they could detect against the dark sky, the darker shadow of its outline; then they turned to the camp-fire and Ben Stubbs, whistling loudly, almost defiantly, set about the task of getting supper. Both occupants of the camp felt singularly disinclined for talk and it was not until after supper was finished and Ben’s pipe fairly going, that either uttered more than a few perfunctory words.

By that time the storm, into which the Golden Eagle had soared on what proved a fatal voyage, was upon them. It came with the same sharp puff of wind and far-off flash of lightning that had first alarmed the boys.

“I’m going to double-lash that tent,” remarked Ben Stubbs, briefly, after he had washed the tin plates. “This is goin’ to be a hummer and no mistake.”

As for Billy the apprehension he felt would not put itself into words. As the storm increased, though, and he helped Ben Stubbs to what the old sailor called “double-gasket” the waterproof tent, his heart sank.
