Benjamin Banneker was a farmer，inventor，astronomer writer and antislavery supporter．He created the first American—built striking clock．
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．
Every evening for a week，Benjamin sat at the table with the watch．He copied eaeh tiny
wheel and pin．When the week was up，he put the pieces back togelher and returned the watch to its owner．Then Benjamin got a good night’s sleep．
The next day when the farm work was done，Benjamin went into the woods to 1ook for just the right pieces of wood．Not too old，not too dry，not too green，not too soft．
For two years，Benjamin farmed all day and worked on his wood pieces at night．In1753，two years after he had borrowed the watch，Benjamin put all the pieces together．Benjamin had made his own clock．
