When Livingstone gave up his purely missionary labors and turned his life channel into the stream of scientific investigation, the same thoroughness of preparation is shown. He did not work for immediate results, attained by shallow touching of the surface, or for hasty conclusions. His was the close observation and careful and accurate deductions of the mind trained by science to be patient and await results. Rather than be inaccurate, he would wait until he knew he was correct. A quarter of a century after Livingstone died a compatriot of his, Robert Louis Stevenson, said that among the hardest tasks that life sets for a man is "to await occasions, and hurry never." Livingstone learned this thoroughly.

In keeping with the quietness, simplicity, and thoroughness of this truly great man was the meeting between him and Stanley when that redoubtable youth found him in the heart of the Dark Continent. Life is essentially a dramatic thing, for as Carlyle says, "Is not every deathbed the fifth act of a tragedy?" But I sometimes think that we miss the drama and poetry of every-day life because it seems so commonplace. We look abroad and afar for great moments, and great moments pass unheeded each hour. So to those two—the toil-worn and weary explorer and the youthful Stanley, full of enthusiasm, albeit dimmed by the hardships and disappointments of his long search, that moment of first meeting must have seemed essentially commonplace. There was a wonder in the encounter, but like all great emotions and great occasions there was a simplicity, so that the greetings were as commonplace as if occurring in a crowded street. Thirty years had passed since the explorer had dedicated himself to the task of making the world know Africa, and he was an old man, worn-out, bent, frail, and sorrow-stricken. But courage was unfaltering, faith undimmed, power unabated. Had Stanley been a few months later, much of his work would have been lost, and his death even more pitiful than it was—yet he could smile and be patient and unhurried.

As Stanley phrases it, "Suppose Livingstone, following the custom of other travellers, had hurried to the coast, after he had discovered Lake Bangweolo, to tell the news to the geographical world; then had returned to discover Moero, and run away again, then come back once more to discover Kamolondo, and to race back again. But no, he not only discovers the Chambezi, Lake Bangweolo, Luapula River, Lake Moero, Lualaba River, and Lake Kamolondo, but he still tirelessly urges his steps forward to put the final completion to the map of the grand lacustrine river system. Had he followed the example of ordinary explorers, he would have been running backwards and forwards to tell the news, instead of exploring, and he might have been able to write a volume upon the discovery of each lake and earn much money thereby."

This was no negative exploration. It was the hard, earnest labor of years, self-abnegation, enduring patience, and exalted fortitude, such as ordinary men fail to exhibit. And he had achieved a wonderful deed. The finding of the poles, north and south, is no greater feat than his. For, after all, what is it to humanity that the magnetic pole, north or south, is a few degrees east or west of a certain point in the frozen seas and barren ice mountains? What can humanity offer as a reward to those whose bodies lie under cairns of ice save a barren recognition of their heroism? What have their lives served, beyond that of examples of heroism and determination? Bronze tablets will record their deeds, but no races will arise in future years to call them blessed. Cold marble will enshrine their memory; but there will be no fair commerce, nor civilization, nor the thankful prayers of those who have been led to know God.

In his earlier years of exploration, Livingstone became convinced that the success of the white missionary in a field like Africa is not to be reckoned by the tale of doubtful conversions he can send home each year, that the proper work of such men was that of pioneering, opening up, starting new ground, leaving native agents to work it out in detail. The whole of his subsequent career was a carrying out of this idea. It was the idea of commerce, bringing the virgin country within the reach of the world, putting the natives in that relation to the rest of humanity which would most nearly make for their efficiency, if not in their own generation, at least in the next. Shall we not say that this is the truest ideal of social service—to plan, not for the present, but for the future; to be content, not with the barren achievement of exploration, the satisfaction that comes with the saying, "I am the first who has trod this soil!" but to be able to say, "Through me, generations may be helped?"

Says a biographer of Dr. Livingstone, "His work in exploration is marked by rare precision and by a breadth of observation which will make it forever a monument to the name of one of the most intrepid travellers of the nineteenth century. His activity embraced the field of the geographer, naturalist, benefactor of mankind, and it can justly be said that his labors were the first to lift the veil from the 'Dark Continent.'"

During the thirty years of his work he explored alone over one-third of the vast continent; a feat which no single explorer has ever equalled. But it must be remembered that even though he had severed his connection with the missionary society that he regarded himself to the last as a "Pioneer Missionary."

One of the most fascinating subjects of controversy since the time of Herodotus was the problem of the source of the Nile. Poetry, from the description of the Garden of Eden and the writings of Ptolemy to the Kubla Kahn of Coleridge, ran rife over the four fountains out of which flowed the wonderful river. To Livingstone was reserved the supreme honor of settling for all time the secret of this most poetic river of mystery. Long ere this he had been honored with a gold medal from the Royal Geographical Society. How futile must the bit of metal have seemed to this dark, silent man, whose mind had grown away from bauble and tinsel, and who had learned in the silences the real value of the trinkets of the world.

When he had discovered the Victoria Falls, he had completed in two years and a half the most remarkable and most fruitful journey on record, reconstructed the map of Africa, and given the world some of the most valuable land it ever could possess. The vast commercial fields of ivory were opened up to trade; the magnificent power of the Victoria Falls laid bare to the sight of civilized man. We can imagine him standing on the brink of the thunderous cataract of the Victoria gazing at its waters as they dashed and roared over the brink of the precipice,

"—Like stout Cortez—when with eagle eyes
He stared at the Pacific, and all his men
Look'd at each other with a wild surmise,
Silent, upon a peak in Darien."
