LETTER xvi THE PLATEAU OF GOKAB 15 of gypsiferous rock, topped with pure white gypsum, resting on high, steep elevations of red and fawn coloured earths, with outcrops of gravel conglomerate. Yesterday was spent in a very severe expedition of twenty-four miles from Mowaz to the lofty plateau of Gorab, mostly through oak forest, crossing great canons 800 feet deep and more, with almost precipitous sides, descending upon the awful gorge through which the Bazuft passes before it turns round the base of the Kuh- i-Gerra, the monarch of this mass of mountains. The ascents and descents were endless and severe as- we crossed the mountain spurs. It was a simple scramble up and down rock ledges, among great boulders, or up or down smooth slippery surfaces. Even my trusty mule slipped and fell several times. Often the animals had to jump up or down ledges nearly as high as their chests, and through rifts so narrow as only just to admit the riders. In some places it was absolutely necessary to walk, and in attempting to get down one bad place on my own feet I fell and hurt my knee badly—a serious misfortune just at present. After twelve miles of a toilsome march th'e guide led us up among the boulders of a deep ravine to the treeless plateau of Gorab, an altitude of 8000 feet, where the air was fresh and cool. The scenery is on a gigantic scale, and the highly picturesque Bazuft is seen passing through magnificent canons of nearly perpendicular rock, and mak- ing sharp turn's round the bases of lofty spurs, till after a course of singular beauty it joins the Karun at Shalil. It is glorious scenery, full of magnificence and mystery. This beautiful Ab-i-Bazuft, which for a long distance runs parallel with the Karun within fifteen or eighteen miles of it, is utterly unlike it, for the Karun is the most tortuous of streams and the Bazuft keeps a geographically straight course for a hundred miles.
