In the morning Henry saw that the larger column of smoke was gone, but that the smaller remained, and the fact aroused his curiosity.

"What do you make of it?" he asked Shif'less Sol.

"I draws from it the opinion that the main band with the cannon hez started off into the south, but that part o' the warriors hev stayed behind fur some purpose or other."

"My opinion, too. But why has the big force gone and the small one remained?"

"I can't say. It's too much fur me."

Henry had an idea, but hoping that he was mistaken he did not utter it just then.

"If the big band has started south again," he said, "and the absence of the column of smoke indicates it, then all the Indians in this part of the forest have been drawn off. They've long since lost us, and they wouldn't linger here in the hope of running across us by chance, when the great expedition was already on its way."

"That's sound argument, an' so we'll leave our islan' an' make fur the boys."

They picked a path across the mud flats, recrossed the creek and entered the deep forest, where the two felt as if they had come back to their true home. The wonderful breeze, fresh with a thousand odors of spring in the wilderness, was blowing. It did not come across mud flats, but it came through a thousand miles of dark green foliage, the leaves rippling like the waters of the sea.

"The woods fur me," said Shif'less Sol, speaking in a whisper, with instinctive caution. "I like 'em, even when they're full o' warriors lookin' fur my scalp."

The forest here was very dense, and also was heavy with undergrowth which suited their purpose, as they would be able to approach the hollow, unseen and unheard. Henry still did not like the presence of the smaller column of smoke, and when he reached the crest of their first hill he saw that it was yet rising.

"You had a sign last night, and it was a good one," he said to Shif'less Sol, "but I see one now, and I think it is a bad one."

"We'll go on an' find it."

They approached the hollow rapidly, the forest everywhere being extremely dense, but when they were within less than a mile of it both stopped short and looked at each other.

"You heard it?" said Henry.

"Yes, I heard it."

"It wasn't much louder than the dropping of an acorn, but it was a rifle shot."

"O' course it wuz a rifle shot. Neither you nor I could be mistook about that."

"And you noticed where it came from?"

"Straight from the place where Paul and Tom and Long Jim Hart are."

"Which may mean that their presence has been discovered and that they are besieged."

"That's the way I look at it."

"And we must make a rescue."

"That's true, an' we've got to be so mighty keerful about it that we ain't took an' scalped and burned by the savages, afore we've had a single chance at makin' a rescue."

The thought in the minds of the two was the same. They were sure now from the absence of the larger smoke column that the main force had gone south, but that the smaller had remained to take their comrades, whose presence, by some chance, they had discovered. They lay closely hidden for a while, and they heard the report of a second shot, followed by a mere shred of sound which they took to be an Indian yell, although they were not sure.

"Ef the boys are besieged, an' we think they are," said the shiftless one, "they kin hold out quite a while even without our help. So I think, Henry, we'd better go an' see whether the main camp has broke up an' the cannon gone south. It won't be so hard to find out that, an' then we kin tell better what we want to do."

"You're right, of course," replied Henry. "We'll have to leave our comrades for the time and go to the big camp."

They curved again toward the south and west, keeping to the thickest part of the forest and using every possible device to hide their trail, knowing its full necessity, as the day was brilliant and one, unless under cover, could be seen from afar. Game started up in their path and Henry took it as new proof that the main body of the Indians had gone.

Deer, scared away by the hunters, were so plentiful that they would return soon after the danger for them departed. Nevertheless both he and the shiftless one were apprehensive of wandering warriors who might see them from some covert, and their progress, of necessity, was slow.

They came to several gra.s.sy openings, in one of which the buffalo were feeding, but Henry and his comrade always pa.s.sed around such exposed places, even at the cost of greatly lengthening their journey. At one point they heard a slight sound in the forest, and being uncertain whether it was made by an enemy they remained crouched in the thicket at least a half-hour. Then they heard another faint report in the north and their keen ears told them it came from a point near the rocky hollow.

"I can't make anything of it," whispered Henry, "except that the boys are besieged as we feared. I've tried to believe that the shots were fired by Indians at game, but I can't force my belief. The reports all come from the same place, and they mean exactly what we wish they didn't mean."

"But they mean too," said the shiftless one, courageously, "that so long as we hear 'em the boys are holdin' out. The warriors wouldn't be shootin' off their guns fur nothin'."

"That's true. Now, we haven't heard that sound again. It must have been made by a wildcat or a wolf or something of the kind. So let's press on."

The great curve through the forest took them late in the afternoon to the site of the big camp. They were sure, long before they reached it that it had been abandoned. They approached very carefully through the dense woods, and they heard no sound whatever. It was true that a little smoke floated about among the dense leaves, but both were certain that it came from dying fires, abandoned many hours ago.

"You don't hear anything, do you?" asked Henry.

"Not a sound."

"Then they're gone."

Rising from the undergrowth they boldly entered the camp, where perhaps a thousand warriors had danced and sung and feasted and slept for days.

Now the last man was gone, but they had left ample trace of their presence. In the wide open s.p.a.ce lay the charred coals of many fires, and everywhere were heaps of bones of buffalo, bear, dear and wild turkey. Feathers and an occasional paint box were scattered about.

"The feast before the fight," said the shiftless one. "I've a good appet.i.te myself, but it won't hold a candle to that of a hungry warrior."

A low snarling and a pattering of many feet came from the surrounding forest.

"The wolves," said Henry. "They've been here to glean, and they ran away at our approach."

"An' they'll be back the moment we leave."

"Like as not, but we don't care. Here are the wheel tracks, Sol, and there is the road they've cut through the forest. A blind boy could follow the trail of the cannon, and do you know, Sol, I'm bothered terribly."

"Yes, I know, Henry. We've got to turn back, an' save the boys while them warriors, with the English an' the cannon, are goin' on into the south to attack our people."

"And time is often the most precious of all things."

"So it is, Henry."

Henry sat down on one of the logs and cupped his chin in his hands. The problem presented to him was a terrible one, and he was thinking with all his powers of concentration. Should he and Shif'less Sol follow and continue his efforts to destroy the cannon, or return and help their comrades who might be besieged for a week, or even longer? But it was likely that Paul, Long Jim and Silent Tom, with all their resources of skill and courage, would hold out. In the face of a defence such as they could make it would be almost impossible to force the cleft in the cliff, and they had some food and of course unlimited water.

They could be left to themselves, while Shif'less Sol and he hurried on the trail of the Indian army and made their great attempt. Shif'less Sol watched him, as he sat, his chin sunk in his hand, the deep eyes very thoughtful. Presently both looked at the column of smoke not more than a mile away that marked the presence of the smaller camp, the one that had remained and which was undoubtedly conducting the siege. As they looked they heard once more the faint report of a shot, or its echo coming down the wind. Henry stood up, and there was no longer a look of doubt in his eyes.

"Sol," he said, "those three have been with us in a thousand dangers, haven't they?"

"Nigher ten thousand, Henry."
