In the meantime the two friends conferred over the return journey to Mombasa. They had, as it was, penetrated farther and explored more territory than they were commissioned to; they decided, therefore, to return without delay. The captain indeed was lured very much by that lake unknown to geography, but a regard for the health of the children and a desire to return them as quickly as possible to their afflicted fathers prevailed. The doctor insisted, however, that it would be necessary to rest on the cool heights of Kenia Mountain or Mount Kilima-Njaro. From there they also decided to send news to the parents and summon them to come to Mombasa.
The return journey began, after due rest and baths in the warm springs, on the third day. It was at the same time a day of parting from Kali. Stas persuaded the little one that to take him farther with them—to the ocean or to Egypt—would be selfishness on their part. He said to her that in Egypt, and even in England, Kali would be nothing more than a servant, while when he assumed the government of his nation, he, as king, could spread and establish Christianity, soften the savage customs of the Wahimas, and make of them not only a civilized but a good people. The same thing he repeated in substance to Kali.
At the leave-taking, however, a multitude of tears were shed of which even Stas was not ashamed, for he and Nell had passed with Kali through many evil and good moments and not only had learned to appreciate his honest heart, but had conceived a sincere affection for him. The young negro lay long at the feet of his "Bwana kubwa" and the "Good Mzimu." Twice he returned to look at them for a while, but finally the moment of separation came and the two caravans started in opposite directions.
