The bells ring slowly again as the camels wade one after the other through a trench full of salt water. I tighten my knees when my turn comes. I cannot see the water, but I hear it spurting and splashing round the legs of the camels in front of me. Now my camel slides down a nasty mud bank. He slithers and wriggles about to keep himself up, and then he, too, tramps through the water and scrambles up the other side. "Tamarisks," I hear some one shout. Welcome sound! It means that we are safe, for nothing grows in the salt desert. When we come to the first tamarisks we are again on sandy ground. Then all danger is past, and what does it matter if we are dead tired? Two more hours and we reach a village. There Gulam Hussein makes ready a chicken and some eggs, and then I lie down in a hut and sleep as I have never slept before. [Illustration: PLATE VI. TEBBES. The tree in the foreground is a huge tamarisk.] THE OASIS OF TEBBES Any one who has not travelled himself for weeks together through the desert can scarcely conceive what it is to come at length to an oasis. An oasis is to the desert wanderer what a peaceful island with its sheltered anchorage is to mariners. Oases are like stars in the dark vault of heaven, like moments of happiness and prosperity in a man's life. If you had roamed for two months in the wilderness, like myself and my Persians, you would be able to understand our feelings when we at last saw the date-palms of Tebbes beckoning to us in the distance (see map, p. 73). A lofty minaret rises above the little town, which is surrounded by a wall (Plate VI.). Within are old buildings, mosques, and a fort with towers. Outside the town are tilled fields and palm groves. Spring had come when we pitched our tents on a meadow in the shade of thick dark-green palms. There was a rustle and pleasant whisper among the hard fronds when the spring storms swept over the country. We were tired of the everlasting dull yellow tint of the desert and were delighted with the fresh verdure. Outside my tent purled a brook of fine cool water, all the more agreeable after the intense drought of the desert. A nightingale sang in the crown of the palm above my tent. He plays an important part in Persian poetry under the name of _bulbul_. If you were in some mysterious manner transferred to Tebbes, you would on the very first evening wonder what was the curious serenade which you heard from the desert. If you sat at the fall of day reading at the door of your tent, you would look up from your book and listen. You would have an uneasy feeling and be uncomfortable at being alone in the tent. But after the same serenade had been repeated every evening as regular as the sunset, you would become accustomed to it, and at length trouble yourself no more about it.
