But meal-times were among the minor evils; it was in the tents, during the hours when we could do no work, that we suffered most. Rest was impossible. The mere touch of clothing was almost unbearable in the heat, but it was better to swathe the head in a fly-net and roll a blanket round the outlying portions of the body, than to strip to the buff and lie exposed to the attacks of those damnable flies. It is no light thing that sends a strong man into hysterics or drives one sobbing from his tent, to rush about the camp in a frenzy of wild rage. Yet the flies did this--and more; they were carriers of disease. Behind the clouds of flies lurked always the grim spectre of dysentery; and of all our troubles perhaps this is the best known to the people at home. The Mesopotamian Commission ventilated it so thoroughly that there is no need to pile on the agony here. One may say, however, that the sufferings of the men in Egypt from this terrible disease were, certainly in somewhat less degree, those of their comrades farther east. And we will let it go at that. Meanwhile, what of the Turks? During the six weeks we spent putting the camp into a state of defence they kindly refrained from annoying us, and beyond an occasional encounter with our patrols and a false alarm or two, nothing occurred to disturb the even tenor of our digging. When we had finished this strenuous pursuit, every ten days or so flying columns were organised to look for them and, if possible, drive them out of their rocky fastnesses thirty miles away. One of the few vulnerable points in these hills was the Raha Pass and incredibly difficult it was even to approach. The joys of trekking over the sandy desert we knew, the desert in the rainy season we knew, but they were as nothing compared with the rocky desert of Sinai. Not only was there the deep sand to contend with but one had to climb hills and descend valleys covered with huge boulders. It was a creditable feat merely to get over the ground at all; manoeuvring was out of the question. An eight-horse team could with difficulty pull a gun and its limber over fairly level ground; frequently twelve horses were required and sometimes as many as sixteen! And it was really wonderful to see them intelligently thrusting all their weight on the breast-collars, heaving and straining to get their load over a nasty place. These were the days, too, when the heat whipped off the rocks in waves and the sun's rays beat upon the back like strokes from a flail; when it was impossible to march during the noontide hours and one crawled under the limbers for shelter; and when a man looked longingly at his water-bottle, even though the water therein was almost boiling.
