The windmill

16. When its broad sails were set in motion by the wind, he watched the process by which the millstones were made to turn and crush the grain that was put into the hopper. After gaining a thorough knowledge of its construction, he was observed to be unusually busy with his tools.

17. It was not long before his grandmother and all the neighborhood knew what Isaac had been about. He had constructed a model of the windmill. Though not so large, I suppose, as one of the box traps which boys set to catch squirrels, yet every part of the mill and its machinery was complete.

18. Its little sails were neatly made of linen, and whirled round very swiftly when the mill was placed in a draught of air. Even a puff of wind from Isaac's mouth or from a pair of bellows was sufficient to set the sails in motion. And, what was most curious, if a handful of grains of wheat was put into the little hopper, they would soon be converted into snow-white flour.

19. Isaac's playmates were enchanted with his new windmill. They thought that nothing so pretty and so wonderful had ever been seen in the whole world.

"But, Isaac," said one of them, "you have forgotten one thing that belongs to a mill."

20. "What is that?" asked Isaac; for he supposed that, from the roof of the mill to its foundation, he had forgotten nothing.

"Why, where is the miller?" said his friend.

"That is true; I must look out for one," said Isaac; and he set himself to consider how the deficiency should be supplied.

21. He might easily have made a little figure like a man; but then it would not have been able to move about and perform the duties of a miller. It so happened, however, that a mouse had just been caught in the trap; and, as no other miller could be found, Mr. Mouse was appointed to that important office.
