"All right," agreed Russ. "We'll have some fun."
Down the street they went, to a corner, where a big apartment house stood close to the sidewalk. There the pavement was smooth, just the place for spinning tops.
"There, mine's spinning first!" cried Tom, as he flung his top down, quickly pulling the string away, and thus making the top whirl around very fast. "Let's see if either of you can hit my top with yours."
"I can!" said Russ, and he threw his top at Tom's with all his might.
Russ didn't hit his playmate's top, but he did hit something else. Up into the air bounced Russ's top, and, the next moment, there was a crash of glass.
"Oh!" cried Tom. "You've broken a window!"
CHAPTER XIX
FLYING A KITE
That was just what had happened. When Russ threw his top down so hard, it had bounced up again from the sidewalk, and had gone sailing through the air against one of the lower windows of the apartment house which stood so close to the pavement. And the top went right through the glass.
