Note 200 — INTRODUCTION (continued 2)

Elim has been identified with Wadi Gharandel. It is reached in two hours from the bitter spring in the Wadi Hawara, believed to be the Marah of the Bible. Burckhardt conjectures that the juice of the berry of the gharkad, a shrub growing in the neighbourhood, may have the property, like the juice of the pomegranate, of improving brackish water; see p. 475, Baedecker's Egypt, 1879 edition. Professor Lepsius was responsible for the chapter on the Sinai routes.
