We now stand upon the westernmost edge of the great central Arabian plateau, known as El-Nejd ("the Highlands"), opposed to El-Tihámah, the lowland regions. In Africa we should call it the "true" subtending the "false" coast; delightful Dahome compared with leprous Lagos. This upland, running parallel with the "Lip"-range and with the maritime Gháts, is the far-famed Hismá. It probably represents a remnant of the old terrace which, like the Secondary gypseous formation, has been torn to pieces by the volcanic region to the east, and by the plutonic upheavals to the west. The length may be 170 miles; the northern limit is either close to or a little south of Fort Ma'án; and we shall see its southern terminus sharply defined on a parallel with the central Shárr, not including "El-Jaww."[155] An inaccessible fortress to the south, it is approached on the south-west by difficult passes, easily defended against man and beast. Further north, however, the Wadys ‘Afál near El-Sharaf, El-Hakl (Hagul), and El-Yitm at El-‘Akabah, are easy lines without Wa'r ("stony ground") or Nakb ("ravines").

The Hismá material is a loose modern sandstone, showing every hue between blood-red, rose pink, and dead, dull white: again and again fragments had been pointed out to us near the coast, in ruined buildings and in the remains of handmills and rub-stones. Possibly the true coal-measures may underlie it, especially if the rocks east of Petra be, as some travellers state, a region of the Old, not the New Red. According to my informants, the Hismá has no hills of quartz, a rock which appears everywhere except here; nor should I expect the region to be metalliferous.

We ascended the Jebel el-Khuraytah, a trap hillock some 120 feet high, the southern jamb of the Khuraytah gate: the summit, where stands a ruined Burj measuring fourteen metres in diameter, gives a striking and suggestive view. After hard dry living on grisly mountain and unlovely Wady, this fine open plain, slightly concave in the centre, was a delightful change of diet to the eye—the first enjoyable sensation of the kind, since we had gazed lovingly upon the broad bosom of the Wady el-‘Arabah. The general appearance is that of Eastern Syria, especially the Haurán: at the present season all is a sheet of pinkish red, which in later March will turn to lively green. On this parallel the diameter does not exceed a day's march, but we see it broadening to the north. Looking in that direction over the gloomy-metalled porphyritic slopes upon which we stand, the glance extends to a manner of sea-horizon; while the several planes below it are dotted with hills and hill-ranges, white, red, and black, all dwarfed by distance to the size of thimbles and pincushions. The guides especially pointed out the ridge El-Mukaykam, a red block upon red sands, and a far-famed rendezvous for raid and razzia. Nearer, the dark lumps of El-Khayráni rise from a similar surface; nearer still lie the two white dots, El-Rakhamatayn; and nearest is the ruddy ridge Jebel and Jils el-Rawiyán, containing, they say, ruins and inscriptions of which Wallin did not even hear.

The eastern versant of the Hismá is marked by long chaplets of tree and shrub, disposed along the selvage of the watercourses; and the latter are pitted with wells sunk after the fashion of the Bedawin. In this rhumb the horizon is bounded by El-Harrah, the volcanic region whose black porous lavas and honey-combed basalts, often charged with white zeolite, are still brought down even to the coast to serve as mortars and handmills. The profile is a long straight and regular line, as if formed under water, capped here and there by a tiny head like the Syrian Kulayb Haurán: its peculiar dorsum makes it distinguishable from afar, and we could easily trace it from the upper heights of the Shárr. It is evidently a section of the mighty plutonic outburst which has done so much to change the aspect of the parallel Midian seaboard. Wallin's account of it (p. 307) is confined to the place where he crossed the lava-flood; and he rendered El-Harrah, which in Arabic always applies to a burnt region, by "red-coloured sandstone."

The Bedawin far more reasonably declare that this Harrah is not a mere patch as it appears in Wallin's map, a narrow oblong not exceeding sixty miles (north lat. 27°—28°), disposed diagonally from north-west to south-east. According to them, it is a region at least as large as the Hismá; and it extends southwards not only to the parallel of El-Medínah, but to the neighbourhood of Yambú'. The upper region has two great divisions: the Harrat-Hismá or the Harrah par excellence, which belongs to the Ma'ázah, and which extends southwards through El-Sulaysilah as far as the Jaww. The latter region, a tract of yellow sand, dotted with ruddy hills, apparently a prolongation of the Hismá, separates it from the Harrat el-‘Awayraz, in which the Jebel el-Muharrak lies.[156] This line of volcanism is continued south by the Harrat el-Mushrif (P.N. of a man); by the Harrat Sutúh Jaydá; and, finally, by the Harrat el-Buhayri. the latter shows close behind the shore at El-Haurá, in nearly the same latitude as El-Medínah, where we shall presently sight it. There is great interest and a general importance in this large coast-subtending eruptive range, whose eastern counterslope demands long and careful study.

Sweeping the glance round to south, we see the southern of the two Jilsayn, tall mounds of horizontal strata, with ironstone in harder lines and finial blocks. This is the Jils el-Dáim, so distinguished from the northern Jils el-Rawiyán. The lower edge of the Hismá swells up in red and quoin-like masses, the Jibál el-Záwiyah, and then falls suddenly, with a succession of great breaks, into the sub-maritime levels. During our next ten days' travel we shall be almost in continuous sight of its southern ramparts and buttresses. Far over the precipices lie the low yellow sands of the Rahabah, alias the Wady Dámah; and behind it rises the sky-blue mountain block, which takes a name from the ruins of Shaghab and Shuwák.

We breakfasted upon the Khuraytah crest; and Mr. Clarke set out to shoot the fine red-legged "Greek" partridges (caccabis) that haunt the hilltops, whilst the rest of us marched with the caravan to the nearest camping-ground. About a mile from the Col, and lying to the west of the Jils el-Rawiyán, it is supplied with excellent drinking-water by the Miyáh el-Jedayd, lying nine hundred to a thousand metres to the south-east. On the other hand, fuel, here a necessary of life, was wanting; nor could the camels find forage. Thus we were camped upon the western edge of the Hismá. The Ma'ázah Shaykhs, who vainly urged us forwards, showed a suspicious disappointment at our not reaching their quarters on the far side, where, they said, a camel was awaiting to be slaughtered for our reception.

Meanwhile, we were enjoying the reverse of hospitality. The Bedawin evidently now held that all which was ours had become theirs. Their excessive greed made them imprudent. Not satisfied with "eating us up," with a coffee-pot ever on the fire, with demanding endless tobacco, and with making their two garrons devour more barley than our eight mules, they began to debate, aloud as usual, how much ready money they should demand. This was at last settled at four hundred dollars; and the talk was reported to me by the Básh-Buzúk Husayn, whom they had compelled to cook for them. At the same time unpleasant discussions were beginning: "This man stole my camel!" "That man killed my father," already took the form of threats; in fact, I almost repented having brought the Huwaytát and their camels into the trap. Still they all respected Furayj, as might be seen by their rising and making room for him whenever he approached the fire.

At last an evil rumour arose that the Ma'ázah had determined to supply us with transport, and had sent messengers in all directions to collect the animals. This step looked uncommonly like a gathering of war-men. I was sorely disappointed, for more reasons than one. The state of affairs rendered a distant march to the east highly unadvisable. The principal object of this journey had been to investigate the inland depth of the metalliferous deposits; in fact, their extent from west to east. Their north-south length would be easily ascertained, but the width would still remain unknown. The "Land of Midian," through which we have been travelling, has evidently been worked, and in places well worked; thus the only chance of finding a virgin California would be in the unknown tracts lying to the east of the "Harrahs." Too bad to be thwarted in such a project by the exorbitant demands of a handful of thieves!

The disappointment was aggravated by other considerations. From all that I had heard, the Hismá is a region full of archæological interest. Already we were almost in sight of the ruins of Ruáfá, lying to the north between the two white dots El-Rakhamatayn. Further eastward, and north of the pilgrim-station Zát-Hajj, are the remains of Karáyyá, still unvisited by Europeans. Finally, I had been shown, when too late to inspect the place, a fragment of a Nabathæan inscription, finely cut in soft white sandstone:[157] it had been barbarously broken, and two other pieces were en route. The stone is said to be ten feet long (?), all covered with "writings," from which annalistic information might be expected: it lies, or is said to lie, about two hours' ride north of our camp, and beyond the Jils el-Rawiyán famed for Hawáwít. At first I thought of having it cut to portable size; but second thoughts determined me to leave it for another visit or for some more fortunate visitor. Lastly, we were informed, a few weeks afterwards, that the Ma'ázah Shaykhs had carried it off to their tents—I fear piecemeal.
