There were big ones, and little ones, but there were more of the small kind, with little red flags in front, than any other.
"Those are called taxicabs," Aunt Lu told Bunny. "They are like the old cabs, drawn by horses. If a person wants to ride in a taxicab he just waves his hand to the men at the steering wheel."
"And does he stop?" asked Bunny.
"Yes," answered Aunt Lu. "The taxicab man stops."
"And gives 'em a ride?" Sue wanted to know.
"Yes, he takes them wherever they want to go."
Bunny and Sue looked at each other. Their eyes sparkled, and it is too bad Aunt Lu did not see them just then, or she might have said something that would have saved much trouble. But she was busy sewing, and she did not notice Bunny and Sue.
The next day the two children slipped out into the hall, and went down to the street in the elevator.
Once out in the street Bunny and Sue watched until they saw, coming along, one of the little taxicabs, with the red flag up, which meant that no one was having a ride in it just then.
"Hi there!" called Bunny, holding up his hand to the man at the steering wheel.
