After attending to last-minute preparations, the explorers got on their dromedaries and turned the animals toward the north. It was slow traveling through the Ahaggars, with the numerous jagged rocks and peaks standing in their way. They were glad indeed when finally they reached the end of the mountain range and rode over a rocky plain. "Now let's make time," said Mr. Holton. "We'll have it comparatively easy from now on and should get to Wargla inside of a few weeks." "And we're likely to have many more adventures before we again see civilization," remarked Joe. Notwithstanding this, the journey back to Wargla was made without important incident, except that in a region of deep ravines Mr. Lewis's camel missed its footing and came near plunging down a twenty-foot crevice. At Wargla the explorers remained for several days, boxing and crating their specimens and antiquities. Here Fekmah divided the treasure among himself and his friends. They begged him to take much the largest share, but he firmly refused. "If it had not been for you Americans, I would not have had any of the hidden riches," he told them, as they sat in the station awaiting the train to take them to the coast. "It was Bob who did it," said Dr. Kirshner loyally. "It was he who got us out of captivity and brought about the success of the expedition!"
