Alec MacKenzie was a man of considerable means. He belonged to an old Scotch family, and had a fine place in the Highlands, but his income depended chiefly upon a colliery in Lancashire. His parents died during his childhood, and his wealth was much increased by a long minority. Having inherited from an uncle a ranch in the West, his desire to see this occasioned his first voyage from England in the interval between leaving Eton and going up to Oxford; and it was then he made acquaintance with Richard Lomas, who had remained his most intimate friend. The unlikeness of the two men caused perhaps the strength of the tie between them, the strenuous vehemence of the one finding a relief in the gaiety of the other. Soon after leaving Oxford, MacKenzie made a brief expedition into Algeria to shoot, and the mystery of the great continent seized him. As sometimes a man comes upon a new place which seems extraordinarily familiar, so that he is almost convinced that in a past state he has known it intimately, Alec suddenly found himself at home in the immense distances of Africa. He felt a singular exhilaration when the desert was spread out before his eyes, and capacities which he had not suspected in himself awoke in him. He had never thought himself an ambitious man, but ambition seized him. He had never imagined himself subject to poetic emotion, but all at once a feeling of the poetry of an adventurous life welled up within him. And though he had looked upon romance with the scorn of his Scottish common sense, an irresistible desire of the romantic surged upon him, like the waves of some unknown, mystical sea. When he returned to England a peculiar restlessness took hold of him. He was indifferent to the magnificence of the bag, which was the pride of his companions. He felt himself cribbed and confined. He could not breathe the air of cities. He began to read the marvellous records of African exploration, and his blood tingled at the magic of those pages. Mungo Park, a Scot like himself, had started the roll. His aim had been to find the source and trace the seaward course of the Niger. He took his life in his hands, facing boldly the perils of climate, savage pagans, and jealous Mohammedans, and discovered the upper portions of that great river. On a second expedition he undertook to follow it to the sea. Of his party some died of disease, and some were slain by the natives. Not one returned; and the only trace of Mungo Park was a book, known to have been in his possession, found by British explorers in the hut of a native chief.
