Wabash almost to the river, those thunderous tracks make a complete
circle, or loop. Within it lie the retail shops, the commercial hotels,
the theatres, the restaurants. It is the Fifth Avenue (diluted) and the
Broadway (deleted) of Chicago. And he who frequents it by night in
search of amusement and cheer is known, vulgarly, as a Loop-hound.

Jo Hertz was a Loop-hound. On the occasion of those sparse first nights
granted the metropolis of the Middle West he was always present, third
row, aisle, left. When a new loop café was opened Jo's table always
commanded an unobstructed view of anything worth viewing. On entering
he was wont to say, "Hello, Gus," with careless cordiality to the head
waiter, the while his eye roved expertly from table to table as he
removed his gloves. He ordered things under glass, so that his table, at
midnight or thereabouts, resembled a hot-bed that favours the bell
system. The waiters fought for him. He was the kind of man who mixes his
own salad dressing. He liked to call for a bowl, some cracked ice,
lemon, garlic, paprika, salt, pepper, vinegar, and oil and make a rite
of it. People at near-by tables would lay down their knives and forks to
watch, fascinated. The secret of it seemed to lie in using all the oil
in sight and calling for more.

That was Jo--a plump and lonely bachelor of fifty. A plethoric,
roving-eyed and kindly man, clutching vainly at the garments of a youth
that had long slipped past him. Jo Hertz, in one of those pinch-waist
belted suits and a trench coat and a little green hat, walking up
Michigan Avenue of a bright winter's afternoon, trying to take the curb
with a jaunty youthfulness against which every one of his fat-encased
muscles rebelled, was a sight for mirth or pity, depending on one's
vision.
