has lately been visible for several nights in succession.' Other plagues of Egypt are described by Lepsius:-- 'Suddenly the storm grew to a tremendous hurricane, such as I have never seen in Europe, and hail fell upon us in such masses as almost to turn day into night.... Our tents lie in a valley, whither the plateau of the pyramids inclines, and are sheltered from the worst winds from the north and west. Presently I saw a dashing mountain flood hurrying down upon our prostrate and sand-covered tents, like a giant serpent upon its certain prey. The principal stream rolled on to the great tent; another arm threatened mine without reaching it. But everything that had been washed from our tents by the shower was torn away by the two streams, which joined behind the tents, and carried into a pool behind the Sphinx, where a great lake immediately formed, which fortunately had no outlet. Just picture this scene to yourself! Our tents, dashed down by the storm and heavy rain, lying between two mountain torrents, thrusting themselves in several places to the depth of six feet in the sand, and depositing our books, drawings, sketches, shirts, and instruments--yes, even our levers and iron crow-bars; in short, everything they could seize, in the dark foaming mud-ocean. Besides this, ourselves wet to the skin, without hats, fastening up the weightier things, rushing after the lighter ones, wading into the lake to the waist to fish out what the sand had not yet swallowed; and all this was the work of a quarter of an hour, at the end of which the sun shone radiantly again, and announced the end of this flood by a bright and glorious rainbow. 'Now comes the plague of mice, with which we were not formerly acquainted; in my tent they grow, play, and whistle, as if they had been at home here all their lives, and quite regardless of my presence. At night they have already run across my bed and face, and yesterday I started terrified from my slumbers, as I suddenly felt the sharp tooth of such a daring guest at my foot. 'Above me a canopy of gauze is spread, in order to keep off the flies, these most shameless of the plagues of Egypt, during the day, and the mosquitos at night.... Scorpions and serpents have not bitten us yet, but there are very malicious wasps, which have often stung us.
