"The soft tongue struck one of his trailing legs"
Once I saw him stalk a grasshopper, a big lively green fellow that, in a particularly long jump, had come out of the protecting grass and landed on the brown earth directly in front of where K'dunk was catching the flies that were coming in a steady stream to a bait that I had put out for them. Instantly K'dunk turned his attention from the flies to the larger game. Just as his tongue shot out the grasshopper, growing suspicious, jumped for cover. The soft tongue missed him by a hair, but struck one of his trailing legs and knocked him aside. In an instantK'dunk was after him again, his legs scrambling desperately, his eyes blazing, and his tongue shooting in and out like a streak of flame. Just as the grasshopper rose in a hard jump the tongue hit him, and I saw no more. But K'dunk's gulp was bigger and his eyes were closed for a longer period than usual, and there was a loud protesting rustle in his throat as the grasshopper's long legs went kicking down the road that has no turning.
A big caterpillar that I found and brought to K'dunk one day afforded us all another field for rare observation. The caterpillar was a hairy fellow, bristling with stiff spines, and I doubted that the tongue had enough mucilage on it to stick to him. But K'dunk had no such doubts. His tongue flew out and his eyes closed solemnly. At the same time I saw the caterpillar shrink himself together and stick his spines out stiffer than ever. Then a curious thing came out, namely, that K'dunk's mouth is so big and his game is usually so small that he cannot taste his morsel; he just swallows mechanically, as if he were so used to catching his game that it never occurred to him that he could miss. When he opened his eyes and saw the caterpillar in the same place, he thought, evidently, that it was another one which had come in mysteriously on wings, as the flies were coming to my bait. Again his tongue shot out, and his eyes closed in a swallow of delight. But there in front of him, as his eyes opened, was another caterpillar. Such perfect harmony of supply and demand was never known to a toad before.
Again and again his tongue shot out, and each shot was followed by a blink and a gulp. All the while that he kept up this rapid shooting he thought he was getting fresh caterpillars; and all the while the hairy fellow was shrinking closer and closer together and sticking his spines out like a porcupine. But he was getting more mucilage on him at every shot. "That caterpillar is getting too stuck-up to live," presently said little Johnnie, who was watching the game with me; and at the word a hairy ball shot into the wide mouth that was yawning for him, and K'dunk went back to his fly-catching.
It is probably this lack of taste on K'dunk's part that accounts for the astonishing variety in his food. Nothing in the shape of an insect seemed to come amiss to him. Flies, wasps, crickets, caterpillars, doodle-bugs, and beetles of every description were all treated alike to the same red flash of his tongue and the blinking gulp. A half-dozen boys and girls, who were watching the queer pet with me, were put to their wits' end to find something that he would not eat. One boy, who picked huckleberries, brought in three or four of the disagreeable little bugs, known without a name by every country boy, that have the skunk habit of emitting overpowering odors when disturbed, thinking that he had found a poser for our pet; but K'dunk gobbled them up as if they had been set before him as a relish to tickle his appetite. Another brought potato bugs; but these too were fish for K'dunk's net. Then a third boy, who had charge of a kitchen garden, went away wagging his head and saying that he had just picked something that no living thing would eat. When he came back he had a horse-radish bottle that swarmed with squash-bugs, twenty or thirty of the vile-smelling things, which he dumped out on the ground and stirred up with a stick.
Somebody ran and brought K'dunk from one of his hiding-places and set him down on the ground in front of the squirming mess. For a moment he seemed to be eying his proposition with astonishment. Then he crouched down and the swift red tongue-play began. In four minutes, by my watch, every squash-bug that stirred had disappeared, and K'dunk finished the others as fast as we could wiggle them with a straw to make them seem alive.
We gave up trying to beat him on variety after that, and settled down to the apparently simple task of trying to find out how many insects he could eat before calling halt. But even here K'dunk was too much for us; we never, singly or all together, reached the limit of his appetite. Once we fed him ninety rose-bugs without stopping. Another afternoon, when three boys appeared at the same hour, we put our catch together, a varied assortment of flies, bugs, and creeping things, a hundred and sixty-four head all told. Before dark K'dunk had eaten them all, and went hopping off to the garden on his night's hunting—as if he had not already done enough to prove himself our friend for the entire summer.
Later we adopted a different plan and made the game come to K'dunk on its own wings, instead of running all over creation ourselves to catch it for him. Near the barn was a neglected drain where the flies were numerous enough to warn us to look after our sanitation more zealously. Here I built a little cage of wire netting, in which I placed a dead rat and some scraps from the table. When the midday sun found them and made them odorous, big flies began to pour in, with the loud buzzing which seems to be a signal to their fellows; for in ordinary flight the same flies are almost noiseless. Once, however, they find a bit of carrion fit for their eggs, they buzz about loudly every few minutes, and other flies hear them; whereupon their quiet flight changes to a loud buzzing. So the news spreads—at least this seems to help the matter—and flies pour in from every direction.
