It rained so hard that he could not see more than fifty yards away, and in the ravine before his ledge the water ran in a cold stream. The forest looked desolate and mournful, and he would have been desolate and mournful himself if it had not been for the single fact that he was able to keep dry. That made all the difference in the world, and the contrast between his own warm and sheltered lair and the chill and dripping woods and thickets merely heightened his sense of comfort.

When the rain stopped it was followed by an extremely cold night that froze everything tight. Every tree, bush and the earth itself was covered with glittering ice, a vast and intricate network, a wilderness in white and silver. It was alike beautiful and majestic, and it made its full appeal to Henry, but at the same time he knew that his difficulties had been increased. He would have to walk over ice, and, as he passed through the thickets, fragments of ice brushed from the twigs would fall about him. For a while, at least, the Ice Age had returned. It was sure, too, to make game very scarce, as all the animals would stay in their coverts as long as they could at such a time, and he must replenish his supplies of food soon. But that was a difficulty to which he gave only a passing thought. Others pressed upon him with more immediate force.

His moccasins had become worn from long use and they slipped on the ice as if it were glass. He met this difficulty by cutting pieces from one of the blankets and tying them tightly over his feet with thin strips from his buckskin garments. He was then able to walk without slipping, and he made good progress again through the forest, the exertion of travel keeping him warm. Meanwhile he watched everywhere for a sign, a sign from the four, keeping an especial eye for the trees, for it was upon them that the forest runners wrote their letters to one another. In his soul he craved such a letter and he did not really know how intensely he craved it. The bonds of friendship that united the five were the ties of countless hardships and dangers shared, and not one of them would have hesitated an instant to risk his life for any one of the others.

It was characteristic of Henry’s patience and thoroughness that, though he found nothing, he kept on looking. He wanted a letter, and he wanted it so long and with so much concentration that he began to believe he would find it. It was only a short letter that he wished, merely a word from his friends saying they had passed that way. A straight, tall figure, with eager, questing eyes, he went on through the silver forest. When the light wind blew, fragments of the ice that sheathed every bough and twig fell about him and rattled like silver coins as they struck the ice below, but mostly the air was quiet, and the glow from a mighty setting sun began to shoot such deep tints through the silver that it was luminous with red gold. Thinking little now of its beauty and majesty, the hunter pressed on, not the hunter of men nor even a hunter of game, but a hunter for a word.

The mighty sun sank farther. Most of the gold in its rays was gone, and it burned with an intense red fire, lighting up the icy forest with the glow of an old, old world. Henry still looked. The dark would come soon, when he must abandon the search for the word and seek shelter instead. But his hope was still high that he would find it before night closed down.

When the red glow was at its deepest he saw in the very core and heart of it that for which he was looking. Eye-high on the stalwart trunk of an oak were four parallel slashes from the keen blade of a tomahawk. They could not have been put there by chance. A powerful hand had wielded the weapon and the four cuts were precisely horizontal and close together. He had found his word. It was as plain as day. The four had passed there and they had left for him a letter telling him all about it. This was only the first paragraph in the letter, and he would find others farther on, but he devoted a little time to the examination of the first.

He studied minutely the cuts and the cloven edges of the bark, and he decided that they were at least two weeks old. So the letter had been posted some time since, and doubtless its writers had gone on to another region. But if they posted one letter they would post others, and he felt now that communication had been established. True, the chain connecting them was long, but it could be shortened inch by inch.

He made a series of widening circles about the tree, looking for the second paragraph of the letter, and he found it about a hundred yards to the eastward, exactly like the first, four parallel slashes of a tomahawk, eye-high, deep into the trunk of a stalwart oak. He found a third paragraph precisely like the first and the second, a hundred yards farther on, and then no more. But three were enough. They indicated clearly the course of the four which was into the northeast. In the morning he would change his own direction to conform with theirs.

The letter gave him a great surge of the heart, but the night came down quickly, dark and cold, the bitter wind blew again, and the ice fell about him in a rain of chill crystals. He knew that the temperature was falling fast, and that it would be his hardest night so far. He must have a fire, risk or no risk, and it was a full three hours before he was able to coax one from dead wood that he dragged from sheltered recesses. Then it felt so good that he built a second, intending to sleep between them. His supply of food was low, but knowing how needful it was to preserve his strength and the full fresh flow of his blood, he ate of it heartily, and, then when the ground, wet between the fires from the melted ice, had been dried by the heat, he made his bed and slept well, although he awoke once in the night and finding the cold intense put fresh wood on the fires.

The next morning was one of the coldest he had felt, and he was reluctant to leave the beds of coals, but his comrades had given him a sign, and he would not dream of ignoring it. He threw ice upon the fires, and with a sigh felt their heat disappear. Then he followed the trail to the northeast, hunting at intervals for a renewal of the sign lest he go wrong. Three times he found it, always the four cuts, eye-high, always in the trunk of a stalwart oak, and always they led in the direction in which he was going. The cuts were very deep, and he was quite sure that they had been made by Shif’less Sol, who added to remarkable strength wonderful cunning and mastery in the use of a tomahawk.
