He promised a rich reward to the first man who should discover land ahead. This somewhat renewed their courage, and day and night watches were set and the western horizon before them was scanned at all hours. Time and again they thought they saw land ahead, only to find they had mistaken a cloud upon the horizon for the longed-for shore. Flocks of birds flying westward began to be seen. This gave some ground for hope. For surely the birds must be flying toward some land where they could find food, and trees in which to build their nests. Still fear was great in the hearts of all, and Columbus knew that he could not keep the men much longer in suspense, and that if land did not appear soon they would compel him to turn around and retrace his steps whether he wished to or not. Then he thought of all the benighted heathen who had never heard of God's message of love to man through Christ, and he prayed almost incessantly that courage might be given him to go on. Hour after hour he looked across the blue water, day and night, longing for the sight of land. In fact, he watched so incessantly that his eyesight became injured and he could scarcely see at all. At last one night as he sat upon the deck of the ship he was quite sure that a faint light glimmered for a few moments in the distant darkness ahead. Where there is a light there must be land, he thought. Still he was not sure, as his eyesight had become so dim. So he called one of the more faithful sailors to him and asked him what he saw. The sailor exclaimed: "A light, a light!" Another sailor was called, but by this time the light had disappeared and the sailor saw nothing, and Columbus' hopes again sank. Still he felt they must be nearing land. About two o'clock that night the commander of one of the other boats started the cry: "Land! land ahead!" You can well imagine how the shout was taken up, and how the sailors, one and all, rushed to the edge of their ships, leaning far over, no doubt, and straining their eyes for the almost unhoped-for sight. Early the next morning some one of the sailors picked up a branch of a strange tree, lodged in the midst of which was a tiny bird's nest. This was sure evidence that they were indeed near land; for branches of trees do not grow in water, Little by little the land came in sight. First it looked like a dim ghost of a shore, but gradually it grew distinct and clear. About noon the next day the keel of Columbus' boat grounded upon the sand of the newly discovered country. No white man had ever before set eyes upon it. No ship had ever before touched this coast. At last after a long life of working and studying, of hoping and planning, of trying and failing, and trying yet again, he had realized his dream.
