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.
Then Alec MacKenzie read of the efforts to reach Timbuktu, which was the great object of ambition to the explorers of the nineteenth century. It exercised the same fascination over their minds as did El Dorado, with its golden city of Monoa, to the adventurers in the days of Queen Elizabeth. It was thought to be the capital of a powerful and wealthy state; and those ardent minds promised themselves all kinds of wonders when they should at last come upon it. But it was not the desire for gold that urged them on, rather an irresistible curiosity, and a pride in their own courage. One after another desperate attempts were made, and it was reached at last by another Scot, Alexander Gordon Laing. And his success was a symbol of all earthly endeavours, for the golden city of his dreams was no more than a poverty-stricken village.
One by one Alec studied the careers of these great men; and he saw that the best of them had not gone with half an army at their backs, but almost alone, sometimes with not a single companion, and had depended for their success not upon the strength of their arms, but upon the strength of their character. Major Durham, an old Peninsular officer, was the first European to cross the Sahara. Captain Clapperton, with his servant, Richard Lander, was the first who traversed Africa from the Mediterranean to the Guinea Coast. And he died at his journey's end. And there was something fine in the devotion of Richard Lander, the faithful servant, who went on with his master's work and cleared up at last the great mystery of the Niger. And he, too, had no sooner done his work than he died, near the mouth of the river he had so long travelled on, of wounds inflicted by the natives. There was not one of those early voyagers who escaped with his life. It was the work of desperate men that they undertook, but there was no recklessness in them. They counted the cost and took the risk; the fascination of the unknown was too great for them, and they reckoned death as nothing if they could accomplish that on which they had set out.
Two men above all attracted Alec Mackenzie's interest. One was Richard Burton, that mighty, enigmatic man, more admirable for what he was than for what he did; and the other was Livingstone, the greatest of African explorers. There was something very touching in the character of that gentle Scot. MacKenzie's enthusiasm was seldom very strong, but here was a man whom he would willingly have known; and he was strangely affected by the thought of his lonely death, and his grave in the midst of the Dark Continent he loved so well. On that, too, might have been written the epitaph which is on the tomb of Sir Christopher Wren.
Finally he studied the works of Henry M. Stanley. Here the man excited neither admiration nor affection, but a cold respect. No one could help recognising the greatness of his powers. He was a man of Napoleonic instinct, who suited his means to his end, and ruthlessly fought his way until he had achieved it. His books were full of interest, and they were practical. From them much could be learned, and Alec studied them with a thoroughness which was in his nature.
When he arose from this long perusal, his mind was made up. He had found his vocation.
He did not disclose his plans to any of his friends till they were mature, and meanwhile set about seeing the people who could give him information. At last he sailed for Zanzibar, and started on a journey which was to try his powers. In a month he fell ill, and it was thought at the mission to which his bearers brought him that he could not live. For ten weeks he was at death's door, but he would not give in to the enemy. He insisted in the end on being taken back to the coast, and here, as if by a personal effort of will, he recovered. The season had passed for his expedition, and he was obliged to return to England. Most men would have been utterly discouraged, but Alec was only strengthened in his determination. He personified in a way that deadly climate and would not allow himself to be beaten by it. His short experience had shown him what he needed, and as soon as he was back in England he proceeded to acquire a smattering of medical knowledge, and some acquaintance with the sciences which were wanted by a traveller. He had immense powers of concentration, and in a year of tremendous labour acquired a working knowledge of botany and geology, and the elements of surveying; he learnt how to treat the maladies which were likely to attack people in tropical districts, and enough surgery to set a broken limb or to conduct a simple operation. He felt himself ready now for a considerable undertaking; but this time he meant to start from Mombassa.
So far Lucy was able to go, partly from her own imaginings, and partly from what Dick had told her. He had given her the proceedings of the Royal Geographical Society, and here she found Alec MacKenzie's account of his wanderings during the five years that followed. The countries which he explored then, became afterwards British East Africa.
But the bell rang for dinner, and so interrupted her meditations.

They played bridge immediately afterwards. Mrs. Crowley looked upon conversation as a fine art, which could not be pursued while the body was engaged in the process of digestion; and she was of opinion that a game of cards agreeably diverted the mind and prepared the intellect for the quips and cranks which might follow when the claims of the body were satisfied. Lucy drew Alec MacKenzie as her partner, and so was able to watch his play when her cards were on the table. He did not play lightly as did Dick, who kept up a running commentary the whole time, but threw his whole soul into the game and never for a moment relaxed his attention. He took no notice of Dick's facetious observations. Presently Lucy grew more interested in his playing than in the game; she was struck, not only by his great gift of concentration, but by his boldness. He had a curious faculty for knowing almost from the beginning of a hand where each card lay. She saw, also, that he was plainly most absorbed when he was playing both hands himself; he was a man who liked to take everything on his own shoulders, and the division of responsibility irritated him.
At the end of the rubber Dick flung himself back in his chair irritably.
'I can't make it out,' he cried. 'I play much better than you, and I hold better hands, and yet you get the tricks.'
Dick was known to be an excellent player, and his annoyance was excusable.
'We didn't make a single mistake,' he assured his partner, 'and we actually had the odd in our hands, but not one of our finesses came off, and all his did.' He turned to Alec. 'How the dickens did you guess I had those two queens?'
'Because I've known you for twenty
