We had come through hilly and broken country, over low passes and narrow gorges flanking dry river-beds. Then we had entered another immense flat stretch of lut, quite level except an occasional solitary hillock breaking the monotonous line of the horizon here and there. From one of these hillocks (4,300 feet) near our camp of November 21st one got quite an interesting panorama all round.
The highest mountain in sight was still the Naiband peak to the south-west of us. A range which seemed about 50 miles off spread to the north-west, and before it—about 20 miles distant from us—a very long low hill range. In an arc from our west to our north were distinguishable several high pointed peaks. A blackish brown, handsomely cut hill stood prominent a mile or so from us in the middle of the plain.
To the north the country was much broken up and low. There was a stream of salt water running from east to west with thick salt deposits on each side of the water edge. To the north-east the hills showed no peculiar characteristics but to the east and south-east could be observed two short hill-ranges, much indented, of broken up and corroded rock, similar to the many we had already found across the desert. To the north and to the south of the hill range which stood to the east of us there were low passes, and behind them again the flat lut.
The only thing of real interest in the absolutely bare parts of the desert is the geological formation of the soil and the only amusement is to examine the different beautifully coloured stones that can be picked up, such as handsome agates, bits of malachite, crystals, beautiful marbles, and flints. These are all the more interesting when one thinks that most of them may have travelled hundreds, some, thousands of miles to get there, either brought by the water when the country was submerged or shifted on and on by the wind. They all bear marks of travel, and even the hardest are polished smooth, the original natural angles of crystals being in many cases actually worn down and quite rounded. Sand-polished pebbles of red jasper, jasper-conglomerates, chalcedony, quartz and agatescent quartz, pink and brown corroded limestone, and calcite were the most frequently met with.
A desert is, in England, always associated with glorious sunsets. Why this should be so is rather difficult to be understood by anybody reasoning in the right way, because the magnificent tints of a sunset are caused by moisture in the air and not by abnormal dryness. All the time that I was in the desert itself I never saw a sunset that really had half the picturesqueness of one of our most modest sunsets in Europe. The sun disappeared very fast, leaving a slightly yellow glow above the horizon, which soon became greenish by blending with the blue sky and then black with night. The twilight was extremely short.
We seldom saw clouds at all in the desert and when we did they were scrubby, little, patchy, angular lumps at enormous heights above the earth's surface. They were generally white or light grey. Occasionally they were of the fish-bone pattern, in long successive ridges, resembling the waves formed on the sand surface when shifted by wind. Soon after the sun had disappeared behind the horizon, these clouds generally changed their colour from white into black and made long lines stretching for great distances across the sky, but adding no beauty to it.
Naturally, the play of shifting lights and shadows upon the desert when the sun shone above the clouds was quite weird, especially when the last formation of clouds referred to cast long bluish shadows slowly moving upon the brilliantly-lighted, whitish tint of the ground. Lower upon the horizon line a curtain of a dirty brownish tint was generally to be seen, due to particles of sand in the air, otherwise in almost all cases that came under my observation the clouds formed well-defined, thin, clean, horizontal lines, or else when very high up patchy small skiffs.
One missed greatly the fat, rolling, globular clouds which are so common to Europe, and which fill the sky with fantastic forms. There is such a thing as getting tired of an everlasting spread of blue sky and the glow of a roasting sun.
A strong westerly gale swept low over the surface of the desert. It was very cold after sunset, but fortunately we had plenty of tamarisk shrubs at hand and camel dung with which to make big fires.
The river bed below our camp was very wide, but the salt stream itself not more than three to four feet across. It eventually lost itself to the north-west in the desert. The camels had been let loose to graze and had a good feed of tamarisk, which they seemed to enjoy much after their long diet on reduced rations of straw and cotton seeds.
