And he saw another sight too that is not given to every one to see. While he was watching the tumbling water and wondering where it all came from and where it was going, he thought he saw swift-moving shadows flitting from the water below up and into the mill pond above. He never would have been able to discover just what the shadows were if one of them had not paused a moment while halfway to the top of the falling water. It poised itself for one brief instant, as a humming-bird poises over a flower, but during that fraction of time the little boy was able to see that what he thought was a shadow was really a fish going from the water below to the mill pond above. The child could hardly believe his eyes, and for a little while it seemed that the whole world was turned topsy-turvy, especially as the shadows continued to flit from the water below to the mill pond above. And he was still more puzzled when he reported the strange fact to Uncle Remus, for the old negro took the information as a matter of course. With him the phenomenon was almost as old as his experience. The only explanation that he could give of it was that the fish--or some kinds of fish, and he didn't know rightly what kind it was--had a habit of falling from the bottom of the falls to the top. The most that he knew was that it was a fact, and that it was occurring every day in the year when the fish were running. It was certainly wonderful, as in fact everything would be wonderful if it were not so familiar. "We ain't got but one way er lookin' at things," remarked Uncle Remus, "an' ef you'll b'lieve me, honey, it's a mighty one-sided way. Ef you could git on a perch some'rs an' see things like dey reely is, an' not like dey seem ter us, I be boun' you'd hol' yo' breff an' shet yo' eyes." The old man, without intending it, was going too deep into a deep subject for the child to follow him, and so the latter told him about the bull-frog and the butterfly. The statement seemed to call up pleasing reminiscences, for Uncle Remus laughed in a hearty way. And when his laughing had subsided, he continued to chuckle until the little boy wondered what the source of his amusement could be. Finally he asked the old negro point blank what had caused him to laugh at such a rate. "Yo' pa would 'a' know'd," Uncle Remus replied, and then he grew solemn again and sighed heavily. For a little while he seemed to be listening to the clatter of the mill, but, finally, he turned to the little boy. "An' so you done made de 'quaintance er ol' Brer Bull-Frog? Is you take notice whedder he had a tail er no?" "Why, of course he didn't have a tail!" exclaimed the child. "Neither toad-frogs nor bull-frogs have tails. I thought everybody knew that."
