While in West Africa you should always keep an eye lifting for Drivers. You can start doing it as soon as you land, which will postpone the catastrophe, not avoid it; for the song of the West Coaster to his enemy is truly, “Some day, some day, some day I shall meet you; Love, I know not when nor how.” Perhaps, therefore, this being so, and watchfulness a strain when done deliberately, and worrying one of the worst things you can do in West Africa, it may be just as well for you to let things slide down the time-stream until Fate sends a column of the wretches up your legs. This experience will remain “indelibly limned on the tablets of your mind when a yesterday has faded from its page,” or, as the modern school of psychologists would have it, “The affair will be brought to the notice of your sublimated consciousness, and that part of your mind will watch for Drivers without worrying you, and an automatic habit will be induced that will cause you never to let more than one eye roam spell-bound over the beauties of the African landscape; the other will keep fixed, turned to the soil at your feet.”
The Driver is of the species Ponera, and is generally referred to the species anomma arcens. The females and workers of these ants are provided with stings as well as well-developed jaws. They work both for all they are worth, driving the latter into your flesh, enthusiastically up to the hilt; they then remain therein, keeping up irritation when you have hastily torn their owner off in response to a sensation that is like that of red hot pinchers. The full-grown worker is about half an inch long, and without ocelli even. Yet one of the most remarkable among his many crimes is that he will always first attack the eyes of any victim. These creatures seem to have no settled home; no man has seen the beginning or end, as far as I know, of one of their long trains. As you are watching the ground you see a ribbon of glistening black, one portion of it lost in one clump of vegetation, the other in another, and on looking closer you see that it is an acies instituta of Driver ants. If you stir the column up with a stick they make a peculiar fizzing noise, and open out in all directions in search of the enemy, which you take care they don’t find.
These ants are sometimes also called “visiting ants,” from their habit of calling in quantities at inconvenient hours on humanity. They are fond of marching at night, and drop in on your house usually after you have gone to bed. I fancy, however, they are about in the daytime as well, even in the brightest weather; but it is certain that it is in dull, wet weather, and after dusk, that you come across them most on paths and open spaces. At other times and hours they make their way among the tangled ground vegetation.
Their migrations are infinite, and they create some of the most brilliant sensations that occur in West Africa, replacing to the English exile there his lost burst water pipes of winter, and such like things, while they enforce healthy and brisk exercise upon the African.
I will not enter into particulars about the customary white man’s method of receiving a visit of Drivers, those methods being alike ineffective and accompanied by dreadful language. Barricading the house with a rim of red hot ashes, or a river of burning paraffin, merely adds to the inconvenience and endangers the establishment.
The native method with the Driver ant is different: one minute there will be peace in the simple African home, the heavy-scented hot night air broken only by the rhythmic snores and automatic side slaps of the family, accompanied outside by a chorus of cicadas and bull frogs. Enter the Driver—the next moment that night is thick with hurrying black forms, little and big, for the family, accompanied by rats, cockroaches, snakes, scorpions, centipedes, and huge spiders animated by the one desire to get out of the visitors’ way, fall helter skelter into the street, where they are joined by the rest of the inhabitants of the village, for the ants when they once start on a village usually make a regular house-to-house visitation. I mixed myself up once in a delightful knockabout farce near Kabinda, and possibly made the biggest fool of myself I ever did. I was in a little village, and out of a hut came the owner and his family and all the household parasites pell mell, leaving the Drivers in possession; but the mother and father of the family, when they recovered from this unwonted burst of activity, showed such a lively concern, and such unmistakable signs of anguish at having left something behind them in the hut, that I thought it must be the baby. Although not a family man myself, the idea of that innocent infant perishing in such an appalling manner roused me to action, and I joined the frenzied group, crying, “Where him live?” “In him far corner for floor!” shrieked the distracted parents, and into that hut I charged. Too true! There in the corner lay the poor little thing, a mere inert black mass, with hundreds of cruel Drivers already swarming upon it. To seize it and give it to the distracted mother was, as the reporter would say, “the work of an instant.” She gave a cry of joy and dropped it instantly into a water barrel, where her husband held it down with a hoe, chuckling contentedly. Shiver not, my friend, at the callousness of the Ethiopian; that there thing wasn’t an infant—it was a ham!
These ants clear a house completely of all its owner’s afflictions in the way of vermin, killing and eating all they can get hold of. They will also make short work of any meat they come across, but don’t care about flour or biscuits. Like their patron Mephistopheles, however, they do not care for carrion, nor do they destroy furniture or stuffs. Indeed they are typically West African, namely, good and bad mixed. In a few hours they leave the house again on their march through the Ewigkeit, which they enliven with criminal proceedings. Yet in spite of the advantage they confer on humanity, I believe if the matter were put to the human vote, Africa would decide to do without the Driver ant. Mankind has never been sufficiently grateful to its charwomen, like these insect equivalents, who do their tidying up at supremely inconvenient times. I remember an incident at one place in the Lower Congo where I had been informed that “cork fever” was epidemic in a severe form among the white population. I was returning to quarters from a beetle hunt, in pouring rain; it was as it often is, “the wet season,” &c., when I saw a European gentleman about twenty yards from his comfortable-looking house seated on a chair, clad in a white cotton suit, umbrellaless, and with the water running off him as if he was in a douche bath. I had never seen a case of cork fever, but I had heard such marvellous and quaint tales of its symptoms that I thought—well, perhaps, anyhow, I would not open up conversation. To my remorse he said, as I passed him, “Drivers.” Inwardly apologising, I outwardly commiserated him, and we discoursed. It was on this occasion that I saw a mantis, who is by way of being a very pretty pirate on his own account, surrounded by a mob of the blind hurrying Drivers who, I may remark, always attack like Red Indians in open order. That mantis perfectly well knew his danger, but was as cool as a cucumber, keeping quite quiet and lifting his legs out of the way of the blind enemies around him. But the chances of keeping six legs going clear, for long, among such brutes without any of them happening on one, were small, even though he only kept three on the ground at one time. So, being a devotee of personal courage, I rescued him—whereupon he bit me for my pains. Why didn’t he fly? How can you fly, I should like to know, unless you have a jumping off place?
Drivers are indeed dreadful. I was at one place where there had been a white gentleman and a birthday party in the evening; he stumbled on his way home and went to sleep by the path side, and in the morning there was only a white gentleman’s skeleton and clothes.
However, I will dwell no more on them now. Wretches that they are, they have even in spirit pursued me to England, causing a critic to observe that brevi spatio interjecto is my only Latin, whereas the matter is this. I was once in distinguished society in West Africa that included other ladies. We had a distinguished native gentleman, who had had an European education, come to tea with us. The conversation turned on Drivers, for one of the ladies had the previous evening had her house invaded by them at midnight. She snatched up a blanket, wrapped herself round with it, unfortunately allowed one corner thereof to trail, whereby it swept up Drivers, and awful scenes followed. Then our visitor gave us many reminiscences of his own, winding up with one wherein he observed “brevi spatio interjecto, ladies; off came my breeches.” After this we ladies all naturally used this phrase to describe rapid action.
There is another ant, which is commonly called the red Driver, but it is quite distinct from the above-mentioned black species. It is an unwholesome-looking, watery-red thing with long legs, and it abides among trees and bushes. An easy way of obtaining specimens of this ant is to go under a mango or other fruit tree and throw your cap at the fruit. You promptly get as many of these insects as the most ardent naturalist could desire, its bite being every bit as bad as that of the black Driver.
