On the quay in the far distance we could just discern a portly white figure gazing steadfastly out to sea to catch the first glimpse of the steamer which had been awaited so patiently for so long.

IV.
THE IMPERIAL PORPHYRY QUARRIES.

Those who have travelled in Italy, and, in the museums and in the ruins there, have studied the sculpture and the architectural accessories of the Roman Imperial age, will be familiar with that magnificent purple stone known as Imperial Porphyry. It was one of the most highly prized of the ornamental stones employed by the great artists and architects of that age of luxury; and the great distance which it had to be brought, over parched deserts and perilous seas, must have sent its price up beyond the reach of all save the rulers of the earth.

The quarries from which this porphyry was obtained are situated in the region known as Gebel Dukhân, “the Hills of Smoke,” in the Eastern Egyptian Desert, some twenty-seven miles from the Red Sea, opposite the southern end of the Peninsula of Sinai. Two or three travellers during the last century have visited them, and recently the Survey Department of the Egyptian Government has published a technical report on the whole district; but with the exception of this and an article by the German explorer Schweinfurth, the literature on the subject, such as it is, seems to be more or less untraceable. In 1887 a gentleman of the name of Brindley obtained a concession there for the re-working of the quarries, but the project fell through owing to the difficulties of transporting the stone. In 1907 Mr John Wells, the Director of the now defunct Department of Mines, decided to make an expedition to Gebel Dukhân to report on the possibilities of reopening the old works; and it was with considerable pleasure that I received, and found myself able to accept, his invitation to accompany him, in order to see how far the Department of Antiquities could concur in the projects of modern engineers.

Pl. xv.

We set out from Keneh, a town on the Nile some 400 miles above Cairo, in the middle of March: a time of year when one cannot be sure of good weather in Egypt, for the winter and the summer together fight for the mastery, and the hot south winds vie with the cold north winds in ferocity. Sand-storms are frequent in the desert in this month, and these, though seldom dangerous, can be extremely disagreeable. We were, however, most fortunate in this respect; and, in spite of the fact that the winds were strong, I do not recall any particular discomfort experienced from them, though memory brings back the not rare vision of men struggling with flapping tents and flying ropes. Our caravan consisted of some fifty camels, of which about thirty-five carried the baggage and water; a dozen were ridden by ourselves, Mr Wells’ police, our native assistants, and others; and two or three belonged to the Shêkh and the guides.
