morning of Thursday, 27th December, saw our deliverance from the enforced captivity of The Ghôr.

Having halted for a litte, we commenced to examine the cliffs of Jebel Usdum, and to penetrate some of the caves which open into their sides. These caves give egress to the torrents which issue forth after rain, and along their walls the rock salt is constantly melting.

Mr. Hart informs me that the upper surface is composed of shales and marls with gypsum and selenite, much broken, and not consolidated. They do not at all resemble the limestone strata of the Cretaceo-nummulitic formation, of which the adjoining table-land is
