Lieutenant Amir was despatched (January 27th) to seek for basalt, with a small dromedary-caravan, under the lead of Shaykh Furayj. After winding for about two hours along the shore, which is cut by the broad mouths of many a Wady; and whose corallines, grits, and limestones are weathered into the strangest shapes; he left to the right (east) the light-coloured Jebel Sukk. On the southern side of the Wady (Sukk) which drains it to the sea, a hill of the porous stone which the Arabs call "Hajar el-Harrah" appeared. The specimens brought home, si vera sunt exposita, if they be really taken from an outcrop, prove that volcanic centres, detached, sporadic, and unexpected, like those found further north, occur even along the shore. As will afterwards appear, another little "Harrah" was remarked by Burckhardt ("Syria," p. 522), about one hour and a quarter north of Sinaitic Sherm. He says, "Here for the first and only time, I saw volcanic rocks," and he considers that their extension towards Ras Abú(?) Mohammed may have given rise to the name <Greek>. Wellsted,[EN#105] who apparently had not read Burckhardt, makes the same remark. The many eruptive centres in the limestones of Syria and Palestine were discovered chiefly by my late friend, the loved and lamented Charles F. Tyrwhitt-Drake. It would be interesting to ascertain the relation which they bear to tile great lines of vulcanism in the far interior, the Haura'n and the Harrah, subtending the coast mountains. And Dr. Beke, another friend now no more, would have been delighted to know that his "True Mount Sinai" was not unconnected with a volcanic outbreak.
