In the 19the century people from all over the country came here to find gold. Many people bee very rich now. They bought all the ground near the bank of the river. They dug big holes in it, trying to find more gold.
Mike Judeson was one of those who came to find gold. He bought nearly the last piece of the ground. It was a long way from the river, so no one else wanted to buy it. But Mike paid all his money for it. He worked hard month after month, but didn’t find any gold.
Then one night, just before he was going to give it up, it began to rain. It rained for several days and nights. When the rain stopped at last, Mike came out of his small wooden house to see his piece of ground. It didn’t look the same. The holes were not there any more, and a lot of small plants grew everywhere.
“Perhaps there is no gold here.” Mike said. “But this ground is rich. I can grow flowers and sell them for money. The women in this town are rich now. They have beautiful houses and they will put flowers in their houses. If I can grow good flowers here, I can make money, too.” So he did. And soon his piece of ground was covered with beautiful flowers. Later he was able to buy more fields until he owned all the ground near the river.
“I was the only man who found true gold here.” he often said. “The others took their gold out of the ground and went away. But my gold is still here.”
