As to the broad question of canvas _v._ buildings, experience amply showed that in a climate such as is possessed by South Africa, canvas affords the greater advantages. The hospitals are more mobile, more readily extended, and the more healthy. Except under unusual conditions of rain and dust, the patients did excellently in the tents. Rain and dust were occasionally most troublesome, especially when combined with wind. I once saw a whole hospital, fortunately unoccupied, levelled to the ground in the course of some twenty minutes. Under such circumstances iron huts present advantages, and were on many occasions utilised with much success. They are readily erected, and it would have been a considerable improvement if a number of them had been ready for use at the earliest part of the campaign. Except in the matter of weight, they possess in a considerable degree the advantage of mobility possessed by canvas, and in addition they offer much more protection from the weather. On the other hand, they are more liable to become unhealthy from prolonged use. Churches and public institutions were mainly troublesome from the necessity of having to improvise sanitary arrangements, and sometimes the disadvantage of the collection of a large number of men in one chamber could not be avoided. None the less I cannot look back without admiration on the temporary hospitals established in the Raadzaal at Bloemfontein, and the Irish hospital in the Palace of Justice in Pretoria. The State schools in the smaller towns of the Orange River Colony also afforded excellent accommodation as small temporary hospitals. Private houses, possessing the disadvantages of ill-adapted construction and the necessity of a considerably increased staff to work them, were on the whole little used as hospitals. The scattered farmhouses occasionally afforded shelter to very severely wounded men. In most of the country I traversed, however, the farms were so wide apart as to be of little use in this respect; and again, under the special circumstances, patients left in them might have to be abandoned to the enemy. The chief interest during the campaign centred in the working of the Field and General hospitals. Two types of Field hospital were employed, one the Home, the other the Indian. The latter differs from the Home in that in it the bearer company is attached and consists of Indian natives, and that the hospital is separable into four sections in place of two only.
