"Now if there is anything in the woods which always or nearly always points in any one direction, I can find it by looking. Then I can find out which way it points, by remembering how the woods look around home, where I know the points of the compass."
This was an excellent beginning, and Sam straightway began looking for something which should guide him. A patch of sunflowers grew by the creek, and he had heard that they always turn their heads to the sun, but upon examining them, he found some of them turned one way and some another, so that they were of no use whatever. Presently he observed some beautiful green moss growing at the root and for a good many feet up the trunk of a tree, and looking around he saw that the moss at the roots of all the trees grew only or chiefly on one side, and that the covered side was the same with all of them. Here was a uniform habit of vegetation, and Sam knew enough to know that such a habit was not likely to be confined to one particular locality. He began thinking of the woods around home, and especially of a clump of trees in the yard at his father's house, the moss-covered roots of which were Judie's favorite playing place. This moss, he remembered, was nearly all on the north side of the trees, whose southern roots were bare. All the other mossy trees he could remember taught the same lesson, namely, that the green moss which grows around the bases of trees, grows chiefly on the north side. He had no doubt that the law was a general, if not a universal one, and as the mossy trees were very numerous, he had a guide easily followed. Striking out northwardly, therefore, he travelled several miles before stopping, coming then to a suitable resting-place he lay down to gather strength for the night's journey. When night came, however, it had been raining for some hours, and in addition to the darkness of a rainy night in a swamp, Sam found the soft alluvial soil so saturated with water that he sank almost to his knees at every step. Finding it impossible to go on he stopped again on the highest and dryest piece of ground he could find, and prepared to spend the night there. Cutting down a number of thick-leaved bushes he arranged them against a fallen tree, as a shelter.
