When New York City was not very big, there was a market on the East River. On market day all the farmers came there to sell their vegetable, butter and eggs, and fruit. They laughed and talked together, so no one could hear the river that ran beside them.

But Hans ,the butterman , sat without a smile. He sold pounds of butter from a table beside him. Many people said that his butter wasn’t the right weight. They said that his rolls of butter didn’t weigh as much as a pound.

Once the weighmaster came walking down the road. He was looking for people who did not sell the full weight. Someone told him, ”Watch Hans, the butterman.”

Hans had good eyes. He saw the weighmaster and quickly put the piece of gold into the first roll of butter, between the butter and its cover.

A captain was standing beside Hans’s table, and he had seen Hans put the piece of gold into the roll. He stood at Hans’s side when the weighmaster came up to him.

“Good morning,” said the weighmaster.

“Good morning,” said Hans. “I think that you are looking for farmers who trick the people of our town.

“I’m,” said the weighmaster. “Someone told me that your rolls of butter don’t weigh a full pound.”

“Oh yes, they do. Here, Weighmaster. Here is a roll of butter. Weigh it yourself,” said Hans.

Hans took the first roll of butter and gave it to the weighmaster.

The weighmaster took his scales and put the butter onto it. The roll weighed more than a pound.

“I’ve made a mistake,” said the weighmaster. “You are an honest man. There is enough butter in this roll.”

Then the captain stood in front of Hans’s table. “You are an honest man, so I want to buy some of your butter,” he said. Before Hans could speak, the captain picked up the roll of butter with the piece of gold in it. “I’ll take this one.”

Hans’s heart began beating more quickly. “No, not that one. I’ve sold that one to a friend of mine. Take another one.”

“No, I want this one,” said the captain.

“I won’t sell it to you. I told you that I’ve sold it to a friend,” said Hans.

“Don’t make me angry. The weighmaster weighed this roll. Give your friend another one.”

“But I want to give him this one,” said Hans, who was now very uncomfortable.

“I ask you, good Weighmaster,” said the captain angrily, “don’t I have the right to choose the piece of butter that I want? I will pay good money for it.”

“Of course you have the right, Captain,” said the weighmaster. “What are you afraid of, Hans? Aren’t all the rolls of butter alike? Perhaps I have to weigh all of them.”

What could Hans say? What could he do? He had to smile and sell the butter to the captain. The captain gave Hans three cents for the butter.

The captain and the weighmaster walked away together.

“You punished the thief,” said the weighmaster.

“No, he punished himself,” said the captain, smile.
