the course of the Euphrates; then restoring it to its ancient channel as soon as the vaulted passage had been completed. The investigations of Mr. A. H. Layard, M.P., from 1846 to 1851, show that the process of making underground connections was fully understood from the earliest period of Assyrian history. The ancient Egyptians were undoubtedly masters of the art of tunnelling. In a very interesting letter received from our much valued friend George Groves, Esq., the secretary of the Palestine Exploration Fund, enclosing the recent reports of Lieutenant Warren, R.E., the writer says, “you will see by Warren’s papers that there is no lack of tunnels at Jerusalem; in fact, the whole of the rock upon which the city is built, appears to be honeycombed with them, but of what exact age they are, it is impossible for us as yet to tell.” The further reports of Lieutenant Warren cannot fail to be looked for and read with an all-absorbing interest by every lover of biblical literature and history. Already his researches and discoveries show that he is a man with whom his countrymen may well be satisfied. True type of the Englishman, he is earnest, indefatigable, and enduring; incapable of fatigue, he never knows what it is to be beaten. His ordinary work extends not only throughout the day with a temperature varying from 100 to 107, but also far on towards midnight. But at that period of the 24 hours, the Lieutenant says, “the temperature is much cooler.” That is, the thermometer falls to about 80! Recently when having “an attack of incipient fever and not being able to shake it quite off,” he with his faithful assistant and humble companion in all his labours and anxieties, Sergeant Birtles, “who was also very unwell,” went for a three days’ ride through Faghur, &c. “We returned on Saturday quite recovered!” Twelve or thirteen hours a day in the saddle for three successive days, is rather a rough remedy for the cure of fever. We limit ourselves to two extracts from the reports; the first relates to a discovery made as recently as the 1st of September last, which may be truly described as one of very great importance.
