After Farmer Green put the lid with the holes in it over the top of the feeding trough, Grunty Pig began to grow. At last he was getting as much to eat as his brothers and sisters. And the bigger he grew, the more food he wanted. He was always on the watch for some extra tidbit—always rooting about to find some dainty that others had overlooked. Many a delicious piece of carrot, or , or potato-paring rewarded him for his eager searching.  
Still, Grunty Pig was far from satisfied. He had a great to get outside the pen where he lived with the rest of Mrs. Pig's seven children.
 
"Out in the wide world there must be many good things to eat," he thought. "I'd like to find the place where the potato-parings grow."
 
But of all this, Grunty Pig said nothing to anyone. If the chance ever came to slip out of the pen, he intended to take nobody with him. He had not yet caught up with his brothers and sisters in size, even if he had them in the matter of brains. And he feared that any one of them would crowd him away from the good things that he meant to find beyond the walls of the .
 
Little did Mrs. Pig dream what plans filled the head of her son Grunty. When she saw him around the walls of the pen she never once guessed that he could be looking for anything except something to eat. How could she know that Grunty—the littlest of the family—was searching for a place to escape?
 
Now, it happened that there was one loose board in a corner of the pigpen. The nails that once held it had away. Nobody but Grunty Pig had discovered that by pressing against an end of this board one could bend it outward.
 
It was too bad—for him—that he had grown so rapidly. Had he been just a bit smaller he could have squeezed through the opening.
 
Here Grunty met the first real problem of his life. For some days he puzzled over it. One thing was certain: he couldn't make himself smaller, unless he stopped eating. And that was out of the question. In the end he made up his mind that there was only one thing to do: he must make the opening bigger.
 
Day after day Grunty Pig crowded against the loose board. And at last came his reward. Two more nails gave way all at once. Under Grunty's weight the board opened wide. And as he slipped through the space, to freedom, the board snapped back into place again.
 
There he was, with the wide world before him. And there was the pen, with no opening anywhere to be seen.
 
With a of delight Grunty Pig out of the low building and found himself on the edge of Farmer Green's .
 
He noticed that there was a smell of apples in the air.
