Suddenly hundreds of moles came scampering along, and began to burrow down through the earth, making many holes for air to go in; for they know how to build galleries through the ground better than men can. Every one was so surprised they stopped to look on; for the dirt flew like rain as the busy little fellows scratched and bored as if making an underground railway.

"What does it mean?" said the men. "They work faster than we can, and better; but who sent them? Is this strange little girl a fairy?"

Before Rosy could speak, all heard a shrill, small voice singing,--

"They come at my call;
And though they are small,
They'll dig the passage clear:
I never forget;
We'll save them yet,
For love of Rosy dear."

Then all saw a little gray mouse sitting on a stone, waving her tail about, and pointing with her tiny paw to show the moles where to dig.

The men laughed; and Rosy was telling them who she was, when a cry came from the pit, and they saw that the way was clear so they could pull the buried men up. In a minute they got ropes, and soon had ten poor fellows safe on the ground; pale and dirty, but all alive, and all shouting as if they were crazy,--

"Tom's got it! Tom's got it! Hooray for Tom!"

"What is it?" cried the others; and then they saw Tom come up with the biggest lump of gold ever found in the mountains.

Every one was glad of Tom's luck; for he was a good man, and had worked a long time, and been sick, and couldn't go back to his wife and child. When he saw Rosy, he dropped the lump, and caught her up, saying,--

"My little girl! she's better than a million pounds of gold."
