Fifth Avenue: 1. The widow's chance. 2. A rabbit-warren. 3. The underworld of the upper world. (Fifth Avenue begins at the Washington Arch and really ends at Fifty-ninth Street. Above Fifty-ninth Street one goes into the sacred precincts of monasteries and nunneries. In this district the inhabitants are divided into two classes: those who barely live and those who live barely.)
Fly: A sententious, epigrammatic stylist who puts a period after each utterance.
