"I'll write the address for you, anyway," rejoined Kerns, scribbling it and handing the card to his friend. Then he went down the stairs, several at a time, eased in conscience, satisfied that he had done his duty by a friend he cared enough for to breakfast with. "Of course," he ruminated as he crawled into a hansom and lay back buried in meditation--"of course there may be nothing in this Keen & Co. business. But it will stir him up and set him thinking; and the longer Keen & Co. take to hunt up an imaginary lady that doesn't exist, the more anxious and impatient poor old Jack Gatewood will become, until he'll catch the fever and go cantering about with that one fixed idea in his head. And," added Kerns softly, "no New Yorker in his right mind can go galloping through these five boroughs very long before he's roped, tied, and marked by the 'only girl in the world'--the _only_ girl--if you don't care to turn around and look at another million girls precisely like her.

First, he went to his hatters, looked at straw hats, didn't like them, protested, and bought one, wishing he had strength of mind enough to wear it home. But he hadn't.

Every day for years he had had glimpses of girls whose hair, hands, figures, eyes, hats, carriage, resembled the features required by his ideal; there always was something wrong somewhere. And, as he strolled moodily, a curious feeling of despair seized him--something that, even in his most sentimental moments, even amid the most unexpected disappointment, he had never before experienced. "I do want to love _somebody_!" he found himself saying half aloud; "I want to marry; I--" He turned to look after three pretty children with their maids--"I want several like those--several!--seven--ten--I don't care how many! I want a house to worry me, just as Tommy described it; I want to see the same girl across the breakfast table--or she can sip her cocoa in bed if she desires--" A slow, modest blush stole over his features; it was one of the nicest things he ever did. Glancing up, he beheld across the way a white sign, ornamented with strenuous crimson lettering: KEEN & CO. TRACERS OF LOST PERSONS
