Jon’s desire to explore the road leading to the northward grew so strong, that he at last yielded to it. But first he made every arrangement for the safety of the sheep during his absence. He secured the ram Thor by a long tether and an abundance of cut grass, concealed the rest of his diminishing supply of provisions; climbed the nearest heights and overlooked the country on all sides without discovering a sign of life, and then, after a rest which was more like a waking dream than a slumber, began his strange and solitary journey.
The sun had just become visible again, low in the northeast, when he reached the level of the table-land. There were few clouds in the sky, and but little wind blowing; yet a singular brownish haze filled the air, and spots of strong light soon appeared on either side of the sun. Jon had often seen these “mock suns” before; they are frequent in northern latitudes, and are supposed to denote a change in the weather. The phenomenon, and the feeling of heaviness in the air, led him to study the landmarks very keenly and cautiously as he advanced. In two or three hours he had passed the limits of his former excursions; and now, if a storm should arise, his very life might depend on his being able to find the way back.
During the day, however, there was no change in the weather. The lonely, rugged mountains, the dark little lakes of melted snow lying at their feet, the stony plain, with its great, irregular fissures where the lava had cracked in cooling,—all these features of the great central desert of Iceland lay hard and clear before his eyes. Like all persons who are obliged to measure time without a watch or clock, he had a very correct sense of the hours of the day, and of the distances he walked from point to point. Where there was no large or striking object near at hand, he took the trouble to arrange several stones in a line pointing to the next landmark behind him, as a guide in case of fog.
It was an exciting, a wonderful day in his life, and Jon never forgot it. He never once thought of the certain danger which he incurred. Instead of fear, he was full of a joyous, inspiring courage; he sang and shouted aloud, as some new peak or ridge of hills arose far in front, or some other peak, already familiar, went out of sight far behind him. He scarcely paused to eat or rest, until nearly twelve hours had passed, and he had walked fully thirty miles. By that time the sun was low in the west, and barely visible through the gathering haze. The wind moaned around the rocks with a dreary, melancholy sound, and only the cry of a wild swan was heard in the distance. To the north the mountains seemed higher, but they were divided by deep gaps which indicated the commencement of valleys. There, perhaps, there might be running streams, pastures, and the dwellings of men!
