To assist in the preservation of health everyone was encouraged to lie down during the heat of the day, to keep the hair of the head cut short, make frequent use of the shower baths, and consume no liquor, except such as could be obtained within the camp. Undoubtedly the root cause of many of the ailments was the pollution of the desert soil. One had only to observe the habits of the natives to become aware that the earth of Cairo and its environs was saturated with the filth of ages. This was stirred up by the feet of the infantrymen in training and by the horses going to exercise or water. Horses were numerous about this time. The brigades of Light Horse on Gallipoli had left their mounts behind. These, augmented in August by the 2nd Mounted Division, totalled nearly 10,000, and were cared for in a large Remount Depot established not far from Abbasia Camp. The dust caused by them was at times almost intolerable and the subject of frequent protests by those who soldiered on foot. [Illustration: MAJOR J. KENNY, A.A.M.C. The Regimental Medical Officer.] [Illustration: CAPTAIN J. J. S. SCOULER. Signalling Officer, 1915-16.] The method of dealing with the sick was as follows: A "sick parade" was held daily at the medical officer's tent at 5.30 a.m. and again at 2.30 p.m. All men feeling unwell attended this parade, were examined, and were prescribed for according to their condition. If their symptoms were those of a complaint likely to lay them up, or render them unfit for duty for several days, they would be "evacuated" to a neighbouring hospital and detained there for treatment. Once a man was evacuated he ceased, for all practical purposes, to be a member of the Battalion and came under the control of the medical administration. If he was quickly cured of his complaint he was sent back to his unit. If, on the other hand, his recovery was retarded, he remained for some time in hospital, or in a convalescent depot, and, perhaps, finally returned to Australia either for a change or discharge. Through sickness, transfers, and one or two other causes, the wastage in the Battalion was considerable. This was partly replaced on the 17th August by a first draft from the reinforcements camped at Zeitun. Lieut. J. Quilty brought over 84 and 54, respectively, from the 1st and 2nd Reinforcements. These were also first class men and were quickly absorbed into the companies.
