But after leaving Mount Linde, naught else remained to do than to go ahead continually eastward. Linde indeed had said that this journey was beyond the strength of an experienced and energetic traveler, but Stas had already acquired a great deal of experience, and as to energy, why, as Nell was concerned, he determined to use as much of it as might be necessary. In the meantime it was essential to spare the strength of the little girl; so he decided to travel only from six until ten o'clock in the forenoon, and to make the second march from three to six in the afternoon only in case that at the first stopping place there was no water.

But in the meantime, as the rain fell during the massica quite copiously, they found water everywhere. The little lakes, formed by the downpours in the valleys, were still well filled, and from the mountains flowed here and there streams, pouring crystalline, cool water in which bathing was excellent and at the same time absolutely safe, for crocodiles live only in the greater waters in which fish, which form their usual food, are to be found.

Stas, however, did not permit the little girl to drink crude water as he had inherited from Linde a filter whose action always filled Kali and Mea with amazement. Both seeing how the filter, immerged in a turbid, whitish liquid, admitted to the reservoir only pure and translucent water, lay down with laughter and slapped their knees with the palms of their hands in sign of surprise and joy.

On the whole, the journey at the beginning progressed easily. They had from Linde considerable supplies of coffee, tea, sugar, bouillon, various preserves, and all kinds of medicine. Stas did not have to save his packs for there were more of them than they could take along; they did not lack also various implements, weapons of all calibers, and sky-rockets, which on encountering negroes might prove very useful. The country was fertile; game, therefore fresh meat, was everywhere in abundance, likewise fruit. Here and there in the low lands they chanced upon marshes, but still covered with water, therefore not infecting the air with their noxious exhalations. On the table-land there were none of the mosquitoes which inoculate the blood with fever. The heat from ten o'clock in the morning became unbearable but the little travelers stopped during the so-called "white hours" in the deep shade of great trees, through the dense foliage of which not a ray of the sun could penetrate. Perfect health also favored Nell, Stas, and the negroes.

On the fifth day Stas rode with Nell on the King, for they had chanced upon a wide belt of acacias, growing so densely that the horses could move only on a path beaten down by the elephant. The hour was early, the morning radiant and dewy. The children conversed about the journey and the fact that each day brought them nearer to the ocean and to their fathers, for whom both continually longed. This, from the moment of their abduction from Fayûm, was the inexhaustible subject of all their conversations, which always moved them to tears. And they incessantly repeated in a circle that their papas thought that they already were dead and both were grieving and in spite of hope were despatching Arabs to Khartûm for news while they were now far away, not only from Khartûm but from Fashoda, and after five days would be still farther until finally they would reach the ocean, or perhaps before that time, some kind of place from which they could send despatches. The only person in the whole caravan who knew what still awaited them was Stas;—Nell, on the other hand, was most profoundly convinced that there was nothing in the world which "Stes" could not accomplish and she was quite certain that he would conduct her to the coast. So many times, anticipating events, she pictured to herself in her little head what would happen when the first news of them arrived and, chirping like a little bird, related it to Stas. "Our papas are sitting," she said, "in Port Said and weeping, when in comes a boy with a despatch. What is it? My papa or your papa opens it and looks at the signatures and reads 'Stas and Nell.' Then they will rejoice! Then they will start up to prepare to meet us! Then there will be joy in the whole house and our papas will rejoice and everybody will rejoice and they will praise you and they will come and I shall hug tightly papa's neck, and after that we shall always be—together and—"

And it ended in this: that her chin commenced to quiver, the beautiful eyes changed into two fountains, and in the end she leaned her head on Stas' arm and wept from sorrow, longing, and joy at the thought of the future meeting. And Stas, allowing his imagination to roam into the future, divined that his father would be proud of him; that he would say to him: "You behaved as became a Pole;" and intense emotion possessed him and in his heart was bred a longing, ardor, and courage as inflexible as steel. "I must," he said to himself, "rescue Nell. I must live to see that moment." And at such moments it seemed to him that there were no dangers which he was not able to overcome nor obstacles which he could not surmount.

But it was yet far to the final victory. In the meantime they were making their way through the acacia grove. The long thorns of these trees even made white marks upon the King's hide. Finally the grove became thinner and across the branches of the scattered trees could be seen in the distance a green jungle. Stas, notwithstanding that the heat was very oppressive, slipped out of the palanquin and sat on the elephant's neck to see whether there were any herds of antelopes or zebras within view, for he wished to replenish his supply of meat.

In fact, on the right side he espied a herd of ariels, composed of a few head, and among them two ostriches, but when they passed the last clump of trees and the elephant turned to the left, a different sight struck the eyes of the boy. At the distance of about a third of a mile he observed a large manioc field and at the border of the field between ten and twenty black forms apparently engaged at work in the field.

"Negroes!" he exclaimed, turning to Nell.
