"If you were to bring a pail of water from the spring," said Uncle
Robert, "would you say you had so many inches of water?"
"No," said Frank, "it would be quarts, or gallons, or something like that."
"Do you know how much a quart or gallon is, Susie?" asked Uncle Robert.
"Mother has a quart cup in the pantry," said Susie, "that she measures the milk in sometimes, but I don't know how much a gallon is."
"My new milk pail," said Mrs. Leonard, who sat beside the window sewing, "holds just two gallons."
"Let's see how many quarts it takes to fill it," said Susie.
So they went into the kitchen, and Susie dipped the water with the quart cup into the tin pail.
"Eight," she said, when the pail would hold no more.
"If the pail holds two gallons, Susie." said Uncle Robert, "how many quarts are there in one gallon?"
"Four." said Susie, counting on her fingers.
