20 PERSONAL NARRATIVE. 



great height on each side. The road from Malkatto to 

 Hadoda passed, as already mentioned, through this 

 gorge ; the beds intersected appear to be horizontal ; 

 farther south, at the extreme end of the spur, they dip 

 east at about 20°, but the dip is not constant, and 

 there has been much disturbance. One stratum, a little 

 north of the road from ZuUa to Komayli, consists of 

 soft lapillse ; it is stratified, and presents the appearance 

 of having been deposited from water, as it contains flakes 

 of mica and fragments, rounded apparently, of volcanic 

 ash. None of these hills present the appearance of 

 having been parts of a distinct cone. 



The plain formed by the alluvial deposits of the 

 Had das, the Komayli stream, and another torrent further 

 south, extends along the coast for about eight mUes 

 south of Zulla, as far as the hot spring of Atf^ or 

 Atzfut, which rises at the edge of a dense cluster of man- 

 grove trees, close to the seashore. The water is brackish, 

 but not sufficiently so to prevent its being drunk' by 

 animals. The rocks which here approach the shore are 

 volcanic, and similar beds skirt the hills for some dis- 

 tance to the west. Farther inland, gneissic rocks crop 

 out, and the range along the edge of the bay to the 

 southward, as far as the Turkish outpost at Arafil^, is 

 composed of metamorphics. On one hill, south of Atzfut, 

 trap rests upon the gneiss at some height above the base 

 of the hill. At Arafil^ trap comes in again^ a small 

 alluvial plain intervening near the sea, on which, at the 

 time of my visit, there was an immense herd, 400 or 

 500 in number, of the fine antelope Gazella Scemmer-
