Both animal and plant life is mainly confined to the drainage lines. Of wild animals suitable for human food, gazelles can be shot fairly frequently in the south part of the area, but are very scarce in the north. Sand grouse and partridges can occasionally be obtained round Abu Saafa, while doves are very abundant in the groves near Bir Akwamtra, at the foot of Gebel Elba. Ibex were never seen with certainty, though their horns and lairs were often found on the mountains. Conies inhabit the rocks near Bir Abraq and Bir Madi. The wild ass has disappeared from the area, as also has the ostrich, though fragments of ostrich eggs picked up here and there, and drawings of this bird on the rocks, attest its presence here in recent times. Vultures, kites, and ravens are everywhere in evidence, and several kinds of smaller birds, such as swallows and wagtails, are often seen about the greener wadis. Lizards of many kinds are to be seen. Scorpions and snakes are seldom met with. Of butterflies and moths, especially the latter, many varieties occur. The common fly occurs in such numbers as to be a great pest, but mosquitoes and sand-flies are practically absent. Camel ticks infest the ground under all trees used as shade by travelling Arabs. Earwigs are in some places very abundant, and a great variety of beetles and bugs occur. Near the sea, whole armies of crabs are to be seen marching on the shore, and hermit crabs are very numerous in all sorts of gasteropod dwellings. Of plant life the district contains a great variety. The north and central parts of the area contain the same trees and bushes as abound further north in Egypt,[42] and camel food is moderately abundant. As Elba is approached, many beautiful flowering plants not found further north are met with, while in the clefts of the slopes of Elba itself is a far richer vegetation than occurs wild in any other part of Egypt. I found the approach to Elba was stopped for baggage camels some four kilometres from the summit owing to the closeness of the trees, and the ascent on foot up the clefts of the mountain-face for the remainder of the way was more like going through an English wood than up a desert mountain. Many varieties of sweet-smelling flowers and some fruit-bearing trees unfamiliar in Egypt were seen, while mosses and lichens covered the tumbled masses of granite in many places. Schweinfurth, who examined the botany of this region in 1864, found that of 300 species of plants collected in the Elba district, the vast majority were of Abyssinian types; scarcely 100 were living in other more northerly parts of the Eastern Desert of Egypt, while still fewer are indigenous to the Nile Valley, and only fifteen species were of those found wild in Europe.[43] =Water Supplies.[44]=
