That fall，as usual，Benjamin rode to the nearby town for supplies．He couldn’t wait to get to the end of the road and buy the things his mother wanted．Then he could have a good talk with the folks in town．The truth was，as much as Benjamin loved his mother and father and three sisters，what he really enjoyed was talking about books or math problems or what was happening in other parts of the colonies(殖民地)．

It was about l0 o’clock by the sun when Benjamin arrived at a store．He ordered a bolt(一卷)of white cloth for his mother and looked around for someone to taik to．Benjamin’s heart jumped like a rabbit when he saw a friend holding a gold watch．Benjamin had always wanted to figure out how clocks and watches worked．The friend saw Benjamin and let him sit down for a good talk．

Late that afternoon，Benjamin rode home，slowly．He didn’t want to harm the watch that his friend had let him borrow．That nigh after supper，Benjamin carefully laid the watch on the table and pulled the candle closer．“This is a watch，”he said．“A man in fown lent it to me，and now I’m going to take it apart and draw the pieces．Then 1’11 put it back together again．Benjamin held his breath and gently took the back off the watch．
