its work only just begun, and the publication of results confined to one or two small pamphlets. We now have at least enough reports to make a thick octavo volume, and these so packed with technical details that they will have to be spread out into three volumes more before their information can be grasped by the ordinary reader. We have, moreover, now before us the book called the 'Recovery of Jerusalem,' which is partly such an expansion and partly a comment on the work, with a trifle of new material. The active work of the Society commenced in December, 1865, when Captain Wilson, E.E., and Lieutenant Anderson, E.E., with Corporal Phillips, as photographer, landed at Beyrout, to probe the country from north to south. Captain Wilson was the intelligent officer who had surveyed Jerusalem the previous year, and given us a map of that city, as accurate and reliable in every particular as any map to be had to-day of the city of London. This first expedition, in the course of six months, traversed Palestine from Damascus to Hebron, constructing a series of maps of the entire backbone of the country, excavating at Tel Salhiyeh (near Damascus), at Kedes (Kadesh Naphtali), and Mount Gerizim; examining remains of ancient synagogues, copying old inscriptions, collecting materials for about fifty plans, with detailed drawings of churches, synagogues, mosques, temples, and tombs, and tracing the ancient system of irrigation of the Plain of Gennesareth. The report of this tentative expedition was in favour of Jerusalem as the headquarters of any future exploring party, since that city promised to prove the greatest mine of discoveries, and to yield the quickest results. Accordingly, in November, 1866, we find Lieutenant Warren, R.E., at work in Palestine, at first with only Sergeant Birtles for his assistant, but afterwards with several corporals as well, and with permission to engage a number of native labourers, according to the amount of excavation going on. Lieutenant Warren spent two months in survey-work east and west of Jordan, and then concentrated his energies on Jerusalem, where he laboured at shafts and galleries almost incessantly, till he was invalided home, in May of the year 1870.
