“The one good thing Shadow the Weasel does is to kill Robber the Rat whenever they meet. Robber, as you know, is big and savage and always ready for a fight when cornered. But all the fight goes out of him when Shadow appears. Perhaps it is because he knows how hopeless it is. When Shadow finds a barn overrun with Rats he will sometimes stay until he has killed or driven out the last one. Then perhaps he spoils it all by killing a dozen Chickens in a night. “It is a sad thing not to be able to speak well of any one, but Shadow the Weasel, like Robber the Rat, has by his ways made himself hated by all the little people of the Green Forest and the Green Meadows and by man. There is not one to say a good word for him. Now to-morrow we will meet on the bank of the Smiling Pool instead of here.” CHAPTER XXV Two Famous Swimmers The bank of the Smiling Pool was a lovely place to hold school at that hour of the day, which you know was just after sun-up. Everybody who could get there was on hand, and there were several who had not been to school before. One of these was Grandfather Frog, who was sitting on his big, green, lily pad. Another was Jerry Muskrat, whose house was out in the Smiling Pool. Spotty the Turtle was also there, not to mention Longlegs the Heron. You see, they hadn't come to school but the school had come to them, for that is where they live or spend most of their time. “Good morning, Jerry Muskrat,” said Old Mother Nature pleasantly, as Jerry's brown head appeared in the Smiling Pool. “Have you seen anything of Billy Mink or Little Joe Otter?” “Little Joe went down to the Big River last night,” replied Jerry Muskrat. “I don't know when he is coming back, but I wouldn't be surprised to see him any minute. Billy Mink was here last evening and said he was going up the Laughing Brook fishing. He is likely to be back any time. One never can tell when that fellow will appear. He comes and goes continually. I don't believe he can keep still five minutes.” “Who is that can't keep still five minutes?” demanded a new voice, and there was Billy Mink himself just climbing out on the Big Rock. “Jerry was speaking of you,” replied Old Mother Nature. “This will be a good chance for you to show him that he is mistaken. I want you to stay here for a while and to stay right on the Big Rock. I may want to ask you a few questions.” Just then Billy Mink dived into the Smiling Pool, and a second later his brown head popped out of the water and in his mouth was a fat fish. He scrambled back on the Big Rock and looked at Old Mother Nature a bit fearfully as he laid the fish down. “I--I didn't mean to disobey,” he mumbled. “I saw that fish and dived for him before I thought. I hope you will forgive me, Mother Nature. I won't do it again.”
