     Mr. Seidman treated all his servants (仆人) kindly. Among his servants were two men, named John

and Joseph. John received four dollars a week, and Joseph ten dollars.John's work was always hard.

Joseph's work was much easier. John didn't know why Joseph received more money while doing easier

work. So he decided to ask Mr.Seidman.

     Mr.Seidman listened and said, "I will tell you the reason. But first, do you see that wagon (马车) in

the streets? Please ask the driver what is in his wagon."

     John went out to the street and returned quickly, saying that the wagon was full of wheat (小麦).

     "Where is the wheat going?" asked Mr.Seidman. Again John went out to the wagon.

     "The wheat is to be taken to Brod," he said. Then Mr.Seidan wished to know from where the wheat

came and how much wheat there was in the wagon. Therefore, John made four trips in order to answer

all the questions.

     Then Mr.Seidan called Joseph. "Joseph," he said, "ask the driver what is in his wagon." Joseph quickly

ran out to the street and came back quickly.

     "The driver comes from the town of Sinyava," said Joseph, "but the wheat comes from Svod, and he

is taking it to Brod. Since early morning he has been on the road, and wants to reach Brod before night.

He tells me the wheat crop has been large this year, and we may expect a lower price soon. Is that all, sir?"

     At that moment, John understood, "Joseph thinks while he works."
