“After having inspected the site of the proposed canal I have been piloted by a French aviator over the mysterious deserts. Contrary to my own and most people’s ideas, I found to my delight, that the desert is not all sand. “The story my father once told me, when I was a small boy, came to my mind. He said that the easiest way to catch the lions of Africa was to sift the sands of the deserts, and what did not go through the mesh of the sieve were the lions. “We flew over depressions and mountains, ranging from 100 feet below sea level to 6,000 feet above. In isolated instances, the mountains rose up to a height of 8,000 feet or more. A few of the mountains were of volcanic origin as could be seen from the craters and cones. “It is said that some of these mountainous regions, never actually explored, are the dwelling places of the descendants of pre-historic cave men. Whether this is true or not I cannot say. I kept a sharp lookout for them, but did not succeed in seeing them. “We passed over valleys through which, at one time, water must have flowed. Vast tracts of loose stones and pebbles were to be seen, their surfaces highly polished by the sand winds passing over them. “On every hand there was sand. Sand and more sand. The sand dunes seemed to be without end. These dunes, or sand waves, for that is what they really are, vary in length and height and run diagonally to the prevailing winds. Shifting under the force of the wind, they travel slowly in different directions, filling old depressions and leaving new ones in their wake. Oases have been literally swallowed up by these sand waves, which, in their irresistible march, passed over them and on, leaving no trace of what was previously a garden spot in the desert. “Most curious are the inland mountains, known as the ‘Witness of the Arabs.’ These are the remains of a one-time widely distributed mountain terrace. The sand winds and storms passing over them through the years have robbed them of most of their bulk, leaving only the solid hard cores, which now form a group of flat-topped pyramidal mountains. “While flying over these mountains, a band of savages began shooting at us. They had become frightened at our aeroplane. Luckily we were high enough to be beyond range of their rifles and no damage resulted. “A great many oases were to be seen. Some cover great areas, while here and there are smaller ones. Some of the smaller ones are grouped together. “Most of these oases are rich in vegetation, especially in fruits, such as apples, peaches, oranges, citrons, figs, grapes and pomegranates. The date, however, predominates. The oases are the home of the date palm and these trees play a most important part in desert life. Staple foods, such as corn, wheat, rice, barley, durra and dukhn, are also grown. Besides these a few other tropical products are cultivated.
