CHAPTER XX

THE SMOKE READER

And now we must leave the floating canoe with its occupants and turn to the River Camp, where we left the Boy Aviators overcome with anxiety as to the fate of their young comrades. The situation was indeed one calculated to try the stoutest heart. There was only one drop of sweet in their cup of bitter.

Harry, poking about among the ruins of the deserted camp, had discovered several cans of gasoline that the raiders had overlooked. They formed sufficient fuel with the picric cakes that Frank still had a supply of, to drive the big aeroplane for several hundred miles if the wind conditions were favorable.

But leave the river camp the boys dare not, for they realized that if Billy and Lathrop did manage to make their escape, they would, if possible, come back there. True, it was a chance so remote as to appear almost impossible, but under the circumstances even the shadow of a hope seemed to assume substance. And so they waited, and had been waiting, while the stirring events we have related had been happening to their missing chums.

As if to add to their oppression, old Sikaso mooned about the camp, his eyes rooted to the ground in moody absorption and muttering to himself, "five go—three come back," till Frank angrily ordered him to stop. The realization that his gloomy prophecy seemed only too likely to be fulfilled, however, did not tend to relieve the situation.

"If we do not hear from them to-morrow, we shall be compelled to take to the air and fly to the coast," said Frank as they sat that evening round a camp-fire which had been lighted to keep away marauding lions, whose roars ever and anon shook the forest. At such times old Sikaso's eyes wandered longingly to his great war-axe. There is little doubt that he would have liked to work off his gloomy feelings by tackling a lion single-handed with his weapon.

"You think, then, it isn't worth while waiting if we have heard no news by then?" asked Harry.

"It isn't that," said Frank in reply, "but we have not provisions left to more than tide us over another day. What the Arabs didn't destroy they spoiled."
