"Up the street," answered Randy. "Come on after him." 

"Who's the man you are after?" questioned one of the men who had been interviewing Andy and Fred. 

"He's a young fellow who once went to a military academy with us. He's a regular bully and did something for which he ought to be locked up," was Fred's reply, and then he rushed down into the street, following his three cousins.

What kind of top did the building have?
