Jack's sled was named "Racer," and Jill called hers "Lady Bird."
Their father had to paint the names on the sleds, for the sleds were twins, too.
After school and on Saturday you could often find Jack and Jill, with "Racer" and "Lady Bird," coasting down the hill together.
But this story is not about coasting in the winter.
It is about a slide Jack and Jill took one day in summer.
Mary and Tommy Tucker went to Jack's house one morning to play with the twins.
Jill saw them coming and ran out to meet them.
"Come down to the sand-bank," she cried. "We've got something new down there. Papa gave it to us."
So they all took hold of hands and ran down the hill.
"Be careful, Jack," said Tommy.
