The climate on the western side was a great element no doubt both in the general healthiness of the men and in the general good results seen in the healing of wounds. The days were often hot; thus even in November at Orange River the thermometer registered 115 deg.F. in the single bell tents, but on the other hand the nights were cool and refreshing. The air was very pure and exceedingly dry, while the constant sunshine not only kept up the spirits, but also proved the most efficient disinfector of any ground fouled to less than a serious extent. Dust was our principal bugbear; and when a camp had been settled for a few days, flies; both of these evils increasing rapidly as the stay on any one spot was prolonged. My personal experience of rain was small, but I was twice in camp, once at Orange River and once at Bloemfontein, when very heavy rain fell, and this was sufficient to make the camps terribly uncomfortable for a few days. Under these conditions, as might be expected, until the outbreak of enteric fever the health of the men was remarkably good, minor ailments alone prevailing. One of the most troublesome of these was diarrhoea, which gained the appellation of 'the Modders,' already a classical name as far as South Africa is concerned. This most frequently, I think, depended on errors of diet, combined with the swallowing of a large amount of sand with the food as dust, and in the water drunk. Cases of severe dysentery, however, were also not very uncommon. Rheumatic pains were a common ailment, which, considering the dryness of the atmosphere, would hardly have been expected. Continued fever of a somewhat special type was not uncommon, and was sometimes spoken of under the name of the district, sometimes as veldt fever--of this I will say nothing, as others better fitted to point out its peculiarities will no doubt deal with it. Enteric fever, our chief scourge, I will pass over for the same reason. I might, however, remark from the point of view of one not very experienced in this disease, that in a large number of the fatal cases I happened to see, the actual cause of death seemed to me to be septicaemia from absorption from the mouth. The mouths were unusually bad, even allowing for the often insufficient cleansing that was able to be carried out, and I was inclined to attribute these in some degree to the dryness of the atmosphere, which very quickly and effectively dried up the mucous membrane of the mouth in patients not breathing through the nose, and encouraged the formation of large cracks. Pneumonia was rare, and this was rendered the more striking from the comparatively large number of men who contracted the disease on board ship on the voyage out from England.
