About 2 P.M. we reached Iminteli, the poor village which served as our head-quarters for the next two days. The weather being now settled, our observations for altitude above the sea give nearly the same results when compared with Mogador or with Amsmiz, and that adopted was 4,418 feet (1,346·5 m.). The house of a Jew had been cleared out for our reception. It was of rather more solid construction than that in which we lodged at Arround, in the Aït Mesan valley, but similar in plan. It appeared to be tolerably clean, though on closer scrutiny a few bugs were detected, but in far less numbers than we have seen in Sicily and some other places in Europe. In pursuance of the sheik’s order, the Shelluh inhabitants of this place kept carefully aloof from all communication with us; but there were several Jew families who were clearly well disposed towards the Christian strangers. When we sallied forth, soon after our arrival, to examine the vegetation of the rocky slopes above the village, one of these Jews volunteered to accompany us. Conversation either in Hebrew or Shelluh being unfortunately out of the question, our intercourse was necessarily of the most limited character; but we could not fail to be struck with the man’s air of intelligence and friendliness. The character of the rocks throughout this valley is altogether different from that of the more lofty range which we had previously visited. The red sandstones, there so prevalent, are here absent, and the strata are, without exception, schistose, though seemingly varying much in mineral composition. In some places, and especially on the ridge above Amsmiz, mica is present to an appreciable extent; in others, and notably in the mass of Djebel Tezah, the rock would pass under the old designation of clayslate; while in this part of the valley calcareous schists prevail. Intrusive dykes and bosses of porphyry and other igneous rocks were seen in many places, but not to such an extent as to affect much the general aspect of the surface. The stratification appeared to be very irregular, but in general the beds are inclined at a high angle to the horizon. We were led by the difference in geological structure to anticipate a considerable change in the flora, as compared with that with which we had already made acquaintance; and this expectation was confirmed by what we had seen during our morning’s ride, and still more by our afternoon herborisation on the rocks and slopes above Iminteli.
