At Johanna, or possibly at St. Augustine's, some of our officers and men, moved by that queer propensity of mankind to acquire strange objects, however useless, had bought animals of the kind called mongoos. There were perhaps a half-dozen of these in all. The result was that most of them, one way or another, escaped and took refuge aloft in the rigging, where it was as hopeless to attempt recapture as for a man to pursue a gray squirrel in a tree. The poor beggars had achieved their liberty, however, without the proverbial crust of bread or cup of water; and in consequence, after fasting all day, gave themselves to predatory nocturnal forays, which were rather startling when unexpectedly aroused by them from sleep. The ward-room pantry was near my berth, and I remember being awaked by a great commotion and scuffling, as one or more utensils were upset and knocked about in the unhappy beast's attempt to get at water kept there in a little cask. No reconcilement between them and man was effected, and one by one they dropped overboard, the victims of accident or suicide, noted or unnoted, to their deliverance and our relief. While they lasted it was pathetic to watch their furtive movements and unrelaxed vigilance, jealously guarding the freedom which was held under such hopeless surroundings and must cost them so dear at last. When the ship had rounded Cape Guardafui and fairly entered the Strait of Bab-el-Mandeb, the alteration of weather conditions was immediate and startling. The heat became all at once intense and dry. From the latter circumstance the relief was great. I remember that many years afterwards, having spent a month or more determining a site for a navy-yard in Puget Sound, where the temperature is delightful but the atmosphere saturated, I experienced a similar sense of bodily comfort, when we reached Arizona, returning by the Southern Pacific Railroad. One morning I got up from the sleeper and walked out into the rare, crisp air of a way station, delighted to find myself literally as dry as a bone, and a very old bone, too; tertiary period, let us say. The sudden change in the strait proved fatal to one of our officers. He had been ailing for a few days, but on the night after we doubled the cape woke up from a calm sleep in wild delirium, and in a brief period died from the bursting of an aneurism; an effect which the surgeon attributed to the abrupt increase of heat. I may add that, though dry, the air was felt by us to be debilitating. During the ten days passed in the gulf, young as I then was, I was indisposed to any unusual bodily or mental effort. What breeze reached us, coming over desert from every direction, was like the blast of a furnace, although the height of the thermometer was not excessive.
