My first job, when we at last reached home, was to prepare a deep tin to house the frogs; this I filled with fresh water, and placed a number of stones at the bottom to act as cover for them. I put two of them into this tin, but the third I placed in a large jam jar. While I had my breakfast, the jam jar rested on the table, and between mouthfuls I contemplated my capture with adoring eyes.
My Hairy Frog was, as frogs go, quite large: with his legs tucked neatly in he would have fitted on to a saucer without very much room left over. His head was broad and rather flat, with very protuberant eyes and a mouth with an extraordinarily wide gape. The ground colour of the upper parts was a deep chocolate brown, mottled dimly in places with darker brown, almost black markings; the underside was white, flushed with pink on the lower belly and the inside of the thighs. The eyes were very large, jet black netted with a fine filigree of golden marks. The most astonishing thing about the creature — the hair was confined to the sides of the body and the thighs, where it grew thick and black, about a quarter of an inch long. This adornment is not really hair at all, but consists of fine, elongated filaments of skin, which on close examination resemble the tentacles of a sea anemone. Until you examine the creature closely, however, the illusion that its hindquarters are clothed in a thick layer of fur is complete. In the water the hair stands out, floating like weed, and so is seen to the best advantage; when the frog is out of water the hair takes on a tangled, jelly-like look.
There has been much controversy, ever since the frog was first discovered, over the exact use of this curious hirsute decoration, but it is now believed that the filaments act as an aid to respiration. All frogs breathe, to a certain extent, through their skins: that is to say, the skin absorbs oxygen from the moisture on the creature's body. In this way a frog has, so to speak, two breathing apparatuses – the skin and the lungs. Thus, by breathing through the skin a frog can stay submerged in the water for quite considerable periods. In the case of the Hairy Frog, the great number of filaments give it a much increased skin area, and so must aid its respiration a good deal. There was considerable doubt originally as to the precise function of the Hairy Frog's hairs, owing to the fact that only the male is hairy; the female is smooth-skinned like any ordinary frog. Thus it appeared as though the hairs were purely ornamental rather than useful, for it seemed ridiculous to suppose that the male was so short-winded that he needed hair to enable him to breathe properly, while the female pursued a hairless and well-aerated existence. This unusual discrepapcy was, however, soon explained: it was found that the male spent his life submerged in water, whereas the female led a purely terrestrial existence for the greater part of the year, only going to water during the mating season. So was the mystery explained – the female on land, using her lungs to breathe with for the most part; whereas her husband in his watery lair found the hairs a very useful addition, for much of his time was spent beneath the water.
Next to its hairiness, the most curious thing about this frog is that it possesses, in the fleshy toes of each hind foot, a set of long, semi-transparent white claws; these claws, like those of a cat, are retractile, and when not in use disappear back into the sheaths in the toes. That these claws are sharp and useful had been proved to me by the scratches on my hand. I should imagine that the use of these weapons is twofold: first as a means of defence, and secondly as a useful tool which enables the amphibian to cling to the slippery rocks in the fast-running streams which it inhabits. Whenever the frogs were picked up they would kick out frantically with their hind legs, and the claws would appear from their sheaths; they would at the same time utter their curious screaming grunts, a cross between the cries of a contented pig and tortured mouse, a sound astonishingly loud and inclined to be very startling when you were not expecting it.
My Hairy Frogs settled down very nicely in their large tin, and, after numerous night hunts, I added to their number until I had seven of them, all males with the most luxuriant backsides. For many weeks I searched high and low to try to find some females to go with them, but without success. Then, one day, a dear old lady who looked about ninety-five appeared on the veranda, carrying two calabashes: in one was a pair of shrews, and in the other was a large female Hairy Frog. This was the only female of the species that I ever obtained, and she was accordingly given special care and attention. She was similar to the males in appearance, except that her skin was drier and slightly rougher, and her colouring was a bright brick-red with chocolate flecks. She settled down quite happily with her seven suitors, and even adopted their habits. During the day they all lay in the water, almost completely submerged, ready to dive to the bottom of the tin should anyone approach; at night, however, they grew braver, and climbed out on to the rocks I had put in there for them, where they would sit gulping at each other with vacant expressions. During all the time I had them in Africa, and on the long voyage back to England, the frogs stubbornly refused to eat any of the tempting delicacies I put before them. But as they were extremely fat, this long fast did not unduly worry me, for most reptiles can go for long periods without food and be none the worse for it.
When the time came for me to leave Bafut and travel down to the base camp, and then on to the coast, I packed the frogs in a shallow wooden box filled with wet banana leaves. The box had to be shallow, for otherwise the frogs when scared would jump wildly into the air and bang their delicate noses on the wooden top; in a shallow box, however, they got no chance of doing this. They caused me considerable trouble on the way down from Bafut, and many anxious moments: in the highlands the climate is cool and pleasant, but as you descend into the forested lowlands it is like entering a Turkish bath, and the frogs did not like this change at all. When I opened the box, during one of our halts on the way down, I was horrified to find all my Hairy Frogs lying in the bottom, limp and apparently lifeless. I rushed frantically down into a nearby ravine and plunged the box into a stream. The cool waters gradually revived four of the frogs, but three were too far gone and soon died. This left me with three males and the female. I had to stop the lorry every two or three miles for the rest of the journey while I ducked the frog box into a stream to revive its inmates; and it was only in this fashion that I managed to get them to base camp alive. On arrival, however, I discovered another problem: the Hairy Frogs had not been able to jump and damage their noses, but they had tried to burrow into the corners of the box, and had thus managed to rub all the skin on their noses and upper lips. This was most serious, for once the delicate skin on a frog's nose is damaged it very soon develops a nasty sore on the spot, which spreads like a rodent ulcer, and can eventually eat away the whole nose and lip. Hastily, I had to create a new box for the frogs to live in; this one was also shallow, but it was completely padded inside, top, bottom, and sides, with soft cloth stuffed with cotton wool. The box resembled a small padded cell. In this the Hairy Frogs did very well, since, whether they jumped or burrowed, they could not injure themselves on the soft surface. By keeping them drier than usual I managed to heal up their scraped noses, but they always had faint white scars on the skin afterwards.
