Passage adapted from The Iron Woman by Margaret Deland (1911). 

Elizabeth's long braids had been always attractive to the masculine eye; they had suggested jokes about pigtails, and much of that peculiar humor so pleasing to the young male; but the summer that she "put up her hair," the puppies, so to speak, got their eyes open. When the boys saw those soft plaits, no longer hanging within easy reach of a rude and teasing hand, but folded around her head behind her little ears; when they saw the small curls breaking over and through the brown braids that were flecked with gilt, and the stray locks, like feathers of spun silk, clustering in the nape of her neck; when David and Blair saw these things—it was about the time their voices were showing amazing and ludicrous register—something below the artless brutalities of the boys' sense of humor was touched. They took abruptly their first perilous step out of boyhood. Of course they did not know it…. The significant moment came one afternoon when they all  (10)went out to the toll-house for ice-cream.

There was a little delay at the gate, while the boys wrangled as to who should stand treat. "I'll pull straws with you," said Blair; Blair's pleasant, indolent mind found the appeal to chance the easiest way to settle things, but he was always good-natured when, as now, the verdict was against him. "Come on," he commanded, gayly, "I'll shell out!" Mrs. Todd, who had begun to dispense pink and brown ice-cream, for them when they were very little children, winked and nodded as they all came in together, and made a jocose remark about "handsome couples"; then she trundled off to get the ice-cream, leaving them in the saloon. This "saloon" was an ell of the toll-house; it opened on a little garden, from which a flight of rickety steps led down to a float where half a dozen skiffs were tied up, waiting to be hired. In warm weather, when the garden was blazing with fragrant color, Mrs. Todd would permit favored patrons to put their small tables out among the  (20)marigolds and zinnias and sit and eat and talk.

The saloon itself had Nottingham-lace window-curtains, and crewel texts enjoining remembrance of the Creator, and calling upon Him to "bless our home." The tables, with marble tops translucent from years of spilled ice cream, had each a worsted mat, on which was a glass vase full of blue paper roses; on the ceiling there was a wonderful star of scalloped blue tissue-paper—ostensibly to allure flies, but hanging there winter and summer, year in and year out. Between the windows that looked out on the river stood a piano, draped with a festooning scarf of bandanna handkerchiefs. These things seemed to Blair, at this stage of his esthetic development, very satisfying, and part of his pleasure in "treating" came from his surroundings; he used to look about him enviously, thinking of the terrible dining-room at home; and on sunny days he used to look, with even keener pleasure, at the reflected ripple of light, striking up from the river below, and moving  (30)endlessly across the fly-specked ceiling.

Watching the play of moving light, he would put his tin spoon into his tumbler of ice-cream and taste the snowy mixture with a slow prolongation of pleasure, while the two girls chattered like sparrows, and David listened, saying very little and always ready to let Elizabeth finish his ice-cream after she had devoured her own.

Why does the author most likely include the information about the saloon's appearance (lines 21-26)?
