No space may be found to enumerate all the varieties, but I must mention the Seyleb (_Sanseviera_), whose fleshy tender leaves provided the Nubian nomad with the ordinary material for the cords with which he binds their burdens on his camels. These leaves in shape are not unlike the Nile whips, and on that account may readily recall and stir up painful memories to the poor Nubian of the kurbatch of the Turks, whenever he may chance to see them. So richly burdened are the hanging rocks with the varieties of rarest plants; so large and multiform is the exhibition of scarce and novel succulents—that the greatest enthusiast could hardly fail to be bewildered. As a most interesting development of structural peculiarity, the Lassav, one of the Capparids, demands some notice. It produces flowers which take a form quite unique. A drawing taken from nature shows the strange deformity of the petals, a double cluster of which is attached to the one broad sepal, so as to produce the effect of two handkerchiefs in one pocket. [Illustration: The Lassav (_Capparis galeata_). (Illustration two-thirds of natural size.)] This rich covering of vegetation is, however, confined to the side of the mountains towards the sea; on the other side, as soon as the second pass is left behind, the rocks are bare, and only the lowest part of the valley is covered with anything of luxuriant verdure. Acacias, growing so closely as almost to form a hedge, and gigantic clumps of the grass-green Salvadora, shoot up like great dishes of green salad from the cheerless space around. The moistening vapour of the sea does not reach here to clothe the parched and naked rock. Such were the valleys through which on the morning of the third day we passed on to complete the first stage of our wanderings. Towards midday, after marching for nineteen hours, we had reached Singat, the summer retreat of the town Bedouins of Suakin. The valley of Singat is about a league in breadth. It is enclosed by two lofty mountain chains running parallel to the coast, apparently joined by a number of projecting spurs. On the broad sandy bed of the valley were erected scarcely less than 500 of those Bedouin tents, of which the shape, in their drooping folds, may be compared to what we see in the breast of a roasted fowl. Here, at least a quarter of the population of the town, which reckons 3000 souls, passes the season of refreshing rains. Later, when the mountain valleys are again dry and destitute of pasture, these transient habitations are carried back again; and the camels and goats must find their pasturage on the slopes in the vicinity of the town, which are exposed to the action of the damp sea air.
