To a lover of the desert a journey across its boundless tracts is always full of interest and delight. It is strange what an attraction the desert has for some people, and stranger still is the fact that this magnetic power increases as time passes, and instead of wearying of the wilderness, they love it more and more. And any one who has once heard the call of the desert is always longing to answer that call, and to fly once more, as a needle to its magnet, to that great, wondrous world. For it is a world of its own, this great, boundless ocean of sand--a world altogether different from any other part of God's earth. I once heard an address on "The Desert," and the speaker said that he did not think it possible for any one with an uneasy conscience to bear the solitariness of the desert. Be this as it may, one thing is sure: no one can live and travel in the desert without feeling the majestic Presence of God. Everything speaks of Him, the great sea of sand, the flowers springing into blossom at His word, the tiny lizard darting across your path, and other countless creatures, all finding life and sustenance in the desert, each telling of the wonderful Creator who watches over and cares for all. The songs of the desert, too, are fascinating; songs which, heard elsewhere, would seem incongruous and lacking in harmony. The camel or mule bells, booming out in the silence of the night, remind one of home and loved ones. Often have I been awakened in the night by the sound of the caravan bells, and for a moment thought they were the bells of the dear old church in Devonshire. Then, again, the crooning songs of the muleteer, as he trudges along hour after hour, have a peculiar charm, which grows on one wondrously after a while. And what can be said of the marvellous mirages--visions which come as messengers of hope and leave us victims of despair? For who has not experienced relief and joy at the sight of some beautiful mirage, resembling the welcome sight of a village with trees and water, all apparently within easy reach of the weary traveller, but which in a moment of time vanish, leaving blank disappointment behind. And where can be seen such glorious sunset effects as in the desert? especially when, as is so often the case in Persia, the desert is surrounded by mountains and hills, which catch the after glow, and reflect all those indescribable shades of crimson, gold, and blue, all merging into a beatific and not easily forgotten vision.
