They found that their rivals had arrived just after daylight, and had departed for Colombo, Ceylon, less than twenty minutes before their own appearance. This was cheering news. They had gained a lot on them in crossing the African continent. CHAPTER XXII ABOVE THE CLOUDS Mr. Griggs, the American consul at Aden, proved an affable, pleasant entertainer. His little wife was also very genial and painstaking for their comforts, declaring at their protests that she was doing no more for them than she had done for the other flyers when they came through, a short time before. The couple had two children, a boy and a girl, and both of these plied the boys with innumerable questions about their journey, expressing the greatest interest and excitement when they worked out of Paul the story of the adventure with the gorilla and python. After the meal, which was very appetizing and refreshing, they spent a short time preparing their reports to the _Daily Independent_, and then accompanied their host to the post-office, where the letter and roll of films were mailed. At the telegraph office they received a pleasant surprise in the shape of a message from Mr. Giddings, which stated their reports were coming in to the newspaper all right, and that the greatest interest was being manifested in them by the world in general and by New York people in particular. "Whatever you do, don't let the other crew beat you," were his concluding words. "I have ordered the helium shipped to Nukahiva by fast steamer." "That's good news," said John, with satisfaction, referring to the helium, and the others accorded with him. They dispatched a telegram to Mr. Giddings, and then started out to buy some fruit and other foods. As they went along the narrow, crooking street upon which they had been walking they met so many Arabs with small sprays of dark-green leaves which they put in their mouths and chewed, that their curiosity was aroused, and Bob asked Mr. Griggs what the leaves were. "Those are the leaves of the khat bush," was the response. "You must have passed numerous plantations of such bushes up on the hillsides as you flew over into the basin here. The Yemen Arabs like to chew the leaves so well that they have all of the passion for them that a toper has for whiskey, and they will spend their last rupee for a small bundle." "Does this chewing of the leaves intoxicate them?" asked John. "Oh, no; the leaves are quite harmless. But they do produce a strangely exhilarating effect upon those who chew them. If you ask a Yemen Arab what he chews the leaves for, he will invariably look at you with astonishment and tell you that he forgets all his troubles, sees the most beautiful of fairies and the richest rose-gardens of Allah, and lives in a new world." "Do they go to the fields after it themselves?" inquired Tom.
