Least in size, but in its capacity for annoyance greatest, perhaps, of all, is the sand fly. Almost microscopic, but with delicate grey wings, of a shape that Titania's self might wear, they slip through the holes of mosquito gauze and torment our feet by night and day. The three-day fever they leave behind is yet as nothing compared to the itching fury that persists for days.
Finally there is the bott-fly, by no means the least unpleasant of the tribe. Red-headed and with an iridescent blue body, he is very similar to the bluebottle, and lives in huts and dwellings. But his ways are different, for he bites a hole into one's skin, usually the back or arms, and lays an egg therein. In about ten days this egg develops into a fully grown larva, in other words a white maggot with a black head. It looks for all the world like a boil until one squeezes it and pushes the squirming head outside. But woe to him who having squeezed lets go to get the necessary forceps; for the larva leaps back within, promptly dies and forms an abscess. Often I have taken as many as thirty or forty from one man. It is a melancholy comfort to find that this fly is no respecter of persons, for the Staff themselves have been known to become affected by this pest.
With the flies may be mentioned as one of the minor horrors of war in East Africa, one of the little plagues that are sent to mortify our already over-tortured flesh, the jigger flea. As if there were not already sufficient trials for us to undergo, an unkind Providence has sent this pest to rob us of what little enjoyment or elegant leisure this country might afford. True to her sex, it is the female of the species that causes all the trouble; the male is comparatively harmless. Lurking in the dust and grass of camps, she burrows beneath the skin of our toes, choosing with a calculated ferocity the tender junction of the nails with the protesting flesh. No sooner is she well ensconced therein than she commences the supreme business of life, she lays her eggs, by the million, all enclosed in a little sack. What little measure of sleep the mosquitoes, the sand flies and the stifling nights have left us, this relentless parasite destroys. For her presence is disclosed to us by itching intolerable. Then the skill of the native boys is called upon, and dusky fingers, well scrubbed in lysol, are armed with a safety pin, to pick the little interloper out intact. Curses in many languages descend upon the head of the unlucky boy who fails to remove the sack entire. For the egg-envelope once broken, abscesses and blood poisoning may result, and one's toes become an offence to surgery.
All is well, if a drop of iodine be ready to complete the well-conducted operation; but the poor soldier, whose feet, perforce, are dirty and who only has the one pair of socks, pays a heavy penalty to this little flea, that dying still has power to hurt. Dirt and the death of this tiny visitor result in painful feet that make of marching a very torture. So great a pest is this that at least five per cent. of our army, both white and native, are constantly incapacitated. Hundreds of toenails have I removed for this cause alone. Nor do the jiggers come singly, but in battalions, and often as many as fifty have to be removed from one wretched soldier's feet and legs. So we hang our socks upon our mosquito nets and take our boots to bed with us, nor do we venture to put bare feet upon the ground.
A yell in the sleeping camp at night, "Some damn thing's bit me;" and matches are struck, while a sleepy warrior hunts through his blankets for the soldier ant whose great pincers draw blood, or lurking centipede or scorpion. For in these dry, hot, dusty countries these nightly visitors come to share the warm softness of the army blanket. Next morning, sick and shivering, they come to show to me the hot red flesh or swollen limb with which the night wanderer has rewarded his involuntary host.
NIGHT IN MOROGORO
There's nothing quite so wideawake as a tropical night in Africa. At dawn the African dove commences with his long-drawn note like a boy blowing over the top of a bottle, one bird calling to another from the palms and mango trees. Then the early morning songsters wake.
There is no libel more grossly unfair than that which says the birds of Africa have no song. The yellow weaver birds sing most beautifully, as they fly from the feathery tops of the avenue of coconut palms that line the road to the clump of bamboos behind the hospital.
