From my brood of Short-tailed Blacks, a half-dozen tadpoles wandered off now and then, each scum-mumbling by himself. Shortly his positivism asserted itself and back he wriggled, twisting in and out of the mass of his fellows, or at the approach of danger nuzzling into the dead leaves at the bottom, content only with the feeling of something pressing against his sides and tail. His physical make-up, simple as it is, has proved perfectly adapted to this touch system of life: flat-bottomed, with rather narrow, paddle-shaped tail-fins which, beginning well back of the body, interfere in no way with the pollywog's instincts, he can thigmotact to his heart's content. His eyes are also adapted to looking upward, discerning dimly dangers from above, and whatever else catches the attention of a bottom-loving pollywog. His mouth is well below, as best suits bottom mumbling. Compared with these _polloi_ pollywogs, Redfins were as hummingbirds to quail. Their very origin was unique; for while the toad tadpoles wriggled their way free from egg gelatine deposited in the water itself, the Redfins were literally rained down. Within a folded leaf the parents left the eggs--a leaf carefully chosen as overhanging a suitable ditch, or pit, or puddle. If all signs of weather and season failed and a sudden drought set in, sap would dry, leaf would shrivel, and the pitiful gamble for life of the little jungle frogs would be lost; the spoonful of froth would collapse bubble by bubble, and, finally, a thin dry film on the brown leaf would in turn vanish, and Guinevere and her companions would never have been. But untold centuries of unconscious necessity have made these tree-frogs infallible weather prophets, and the liberating rain soon sifted through the jungle foliage. In the streaming drops which funneled from the curled leaf, tadpole after tadpole hurtled downward and splashed headlong into the water; their parents and the rain and gravitation had performed their part, and from now on fate lay with the super-tads themselves--except when a passing naturalist brought new complications, new demands of Karma, as strange and unpredictable as if from another planet or universe. Only close examination showed that these were tadpoles, not fish, judged by the staring eyes, and broad fins stained above and below with orange-scarlet--colors doomed to oblivion in the native, milky waters, but glowing brilliantly in my aquarium. Although they were provided with such an expanse of fin, the only part used for ordinary progression was the extreme tip, a mere threadlike streamer, which whipped in never-ending spirals, lashing forward, backward, and sideways. So rapid was this motion, and so short the flagellum, that the tadpole did not even tremble or vibrate as it moved, but forged steadily onward, without a tremor.
