The boy looked up wonderingly. He understood Gaelic as well as English, but he did not comprehend his father's words. He had no idea they were prophetic, and that away on the other side of the world, in a land his geography lessons had not yet touched, there stood a great rock, ugly and hard and grim, which he was one day to be called upon to break. CHAPTER II. A VOYAGE OF DISCOVERY The steamship America, bound for Hongkong, was leaving the dock at San Francisco. All was bustle and noise and stir. Friends called a last farewell from the deck, handkerchiefs waved, many of them wet with tears. The long boom of a gun roared out over the harbor, a bell rang, and the signal was given. Up came the anchor, and slowly and with dignity the great vessel moved out through the Golden Gate into the wide Pacific. Crowds stood on the deck to get a last glimpse of home and loved ones, and to wave to friends as long as they could be distinguished. There was one young man who stood apart from the crowd, and who did not wave farewell to any one. He had come on board with a couple of men, but they had gone back to the dock, and were lost in the crowd. He seemed entirely alone. He leaned against the deck-railing and gazed intently over the widening strip of tumbling waters to the city on the shore. But he did not see it. Instead, he saw a Canadian farmhouse, a garden and orchard, and gently sloping meadows hedged in by forest. And up behind the barn he saw a stony field, where long ago he and his brother and the neighbor boys had broken the stones for the new house. His quick movements, his slim, straight figure, and his bright, piercing eyes showed he was the same boy who had broken the big rock in the pasture-field long before. Just the same boy, only bigger, and more man than boy now, for he wore an air of command and his thin keen face bore a beard, a deep black, like his hair. And now he was going away, as he had longed to go, when he was a boy, and ahead of him lay the big frowning rock, which he must either break or be broken upon.
