We left on March the twenty-sixth, while Sir Archibald Murray was attacking Gaza; and rode down Wadi Ais; but after three hours the heat proved too much for me, and we stopped by a great sidr tree (lote or jujube, but the fruit was scarce) and rested under it the midday hours. Sidr trees cast heavy shade: there was a cool east wind, and few flies. Wadi Ais was luxuriant with thorn trees and grass, and its air full of white butterflies and scents of wild flowers; so that we did not remount till late in the afternoon, and then did only a short march, leaving Wadi Ais by the right, after passing in an angle of the valley a ruined terrace and cistern. Once there had been villages in this part, with the underground waters carefully employed in their frequent gardens; but now it was waste.
