The extract which is devoted to the connection between love and money in people's relations is very instructive and thought - provoking. The tone of this piece of  literature is agitated and ironical. O Henry's individual style of writing and rich language becomes obvious due to using of the following stylictic phenomena:

- simile;
  "She had listened to the promulgated wisdom of the 2.999 other girls and had stored it in a brain that was  as secretive and wary as that of a Maltese cat"
   "Masie confronted him behind her counter with a questioning look in eyes as coldly, beautifully, warmly blue as the glint of summer sunshine on an iceberg in Southern seas"
   "She curved an arm, showing like Psyche's through her shirt - waist sleeve..."

- antithesis;

   " Perhaps nature, foreseeing that she would lack wise counsellors, had mingled the saving ingredient of shrewdness along with her beauty..."
   "And a warm glow visited her cool cheeks."
   "... and we will go away from this ugly city to beautiful ones."

- antonomasia;

   "... and as you closed your band over the tape - line for your glovemeasure you thought of Hebe; and as you looked again you wondered she had come by Minerva's  eyes."

   "That is the shopgirl smile, and I enjoin you to shut it unless you are well fortified with callosity of the heart, caramels and a congeniality for the capers of Cupid" 

   "He is the Shylock of the stores"

- periphrasis;

"a floorwalker" - an owner of the store 

"electric runabout" - a car

- repetition;
   "When he comes nosing around, the bridge of his nose is a toll - bridge.", "I want you and I must have you."

   "Masie knew men, especially men who buy gloves"

  "But I've got to be back home by eleven. Ma never lets me stay out after eleven."

- irony;

  "Of course not all floorwalkers are thus. Only a few days ago the papers printed news of one over eighty years of age"

  "Fillial duty took him by the collar and dragged him inside..."

  "I ain't as green as I look"
 "If I could meet a man that got stuck on me the third time he' d seen me I think I'd get   mashed on him."

- epithets;

"glove - counter flirtations", "cheap fellows", "vivacious seconds", "strident string of coquetry", "questioning look", warmly blue eyes", "aristocratically pale face", "intellectual blush", "virginal being", "bright - idea look", "friendly leer", "swell things", "tree-shadowed bench", "golden - bronze head", "amused laugh", "lovely bosom", "eternal summer", etc.

- aposiopesis;
  " If you would allow me to call at your home, I - ... "

  "The streets of the city are water, and one travels about in ..."

- exclamations;
"Oh, gee, no! If you could see our flat once!"
"Permission to call!" 
"Oh, cheese it!"

"Oh, ain't you a kidder!"

- colloquial coinages;
"ma" - mother, "gee" - God, "gent" - gentleman, "kidder" - liar

- rhetorical questions;

"Did you make a hit with his nobs, Masie?", 

"Why did not you ever think of that before?"

"How many other girls did you ever tell that?"

- enumeration;
"The street - corner is her parlor, the park is her drawing - room, the avenue is her garden walk..."

"One day Irving Carter, painter. millionaire, traveller, poet, automobilist happened to enter the Biggest Store."

- metonymy;
  "Tremblingly, awfully her moth wings closed and she seemed about to settle upon the flower of love."
 " Perhaps nature, foreseeing that she would lack wise counsellors, had mingled the saving ingredient of shrewdness along with her beauty, as she has endowed the silver fox of the priceless fur above the other animals with cunning"
 "His mind struggled to recall the nature and habits of shopgirls as he had read or heard of them."

- polysyndeton;
"After the European cities we will visit India and the ancient cities there, and ride on elephants, and see the wonderful temples of the Hindoos and Brahmins..."

- anaphora;

"He didnt know the shopgirl. He didnt know that her home is often either scarsely habitable tiny room or a domicile filled to overflowing with kith and kin."
