But catching frogs gets tiresome after a while, and, after a bit, Bunny and Sue were ready to stop. They looked about for something else to do. Not far from the pond was a high bank of clay, partly dug away. It was like a little hill, and sloped down to the edge of the pond.
"Oh, Sue, I know what let's do!" cried Bunny.
"What?"
"Let's go up to the top of the clay-hill and roll stones down into the water."
"All right—let's!"
Sue set down her can of frogs, and Bunny laid aside his net. The clay-hill was too slippery to climb, so the children went around to the side, on a part where the grass grew. Soon Bunny and Sue stood at the top of the hill. It was not very high, nor very steep, and at the top were a number of stones.
"We'll roll 'em down, and watch 'em splash in the water," said Bunny.
Down the slippery clay slide the children rolled the stones, watching them splash into the little pond at the bottom of the hill.
All of a sudden, as Sue rolled one stone, larger than any of the others she had yet played with, she gave a cry.
"Oh, Bunny! Bunny! I'm slipping! I'm falling!" she called.
