The heat in the tropics was very oppressive, and the horses suffered considerably. One day all the ships carrying horses were turned about and steamed for twenty minutes in the opposite direction in order to obtain a breath of air for the poor animals. In the holds the temperature was 90 deg. and steamy at that. The sight of horses down a ship's hold is a novel one. Each is in a stall of such dimensions that the animal cannot be knocked about. All heads are inwards, and each horse has his own trough. At a certain time in the day lucerne hay is issued. This is the signal for a prodigious amount of stamping and noise on the part of the animals. They throw their heads about, snort and neigh, and seem as if they would jump over the barriers in their frantic effort to get a good feed. Horses on land are nice beasts, but on board ship they are a totally different proposition. One intelligent neddy stabled just outside my cabin spent the night in stamping on an adjacent steam pipe; consequently my sleep was of a disturbed nature, and not so restful as one might look for on a sea voyage. When he became tired, the brute on the opposite side took up the refrain, so that it seemed like Morse signalling on a large scale. We reached Colombo on the 13th January, and found a number of ships of various nationalities in the harbour. Our convoy almost filled it. We were soon surrounded by boats offering for sale all sorts of things, mostly edibles. Of course no one was allowed on board. After arranging for Major Stewart's accommodation at the hospital, we transferred from the ---- to the ----. The voyage was resumed on the 15th. When a few days out, one of the ships flagged that there were two cases of appendicitis on board. The convoy was stopped; the ship drew near ours, and lowered a boat with the two cases, which was soon alongside. Meanwhile a large box which had been made by our carpenter was lowered over the side by a winch on the boat deck; the cases were placed in it and hoisted aboard, where the stretcher-bearers conveyed them to the hospital. Examination showed that operation was necessary in both cases, and the necessary preparations were made. The day was a glorious one--not a cloud in the sky, and the sea almost oily in its smoothness. As the hospital was full of cases of measles, it was decided to operate on deck a little aft of the hospital. A guard was placed to keep inquisitive onlookers at a distance, and the two operations were carried out successfully. It was a novel experience to operate under these conditions. When one looked up from the work, instead of the usual tiled walls of a hospital theatre, one saw nothing but the sea and the transports. After all, they were ideal conditions; for the air was absolutely pure and free from any kind of germ.
