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.
