Chrysanthemums are the central symbol of life, vital energies, sexuality in the story. Just like Elisa herself, they need nurturing and attendance. She lives a boring and unfulfilled life in a dull, loveless marriage, and she has never had a chance of finding her true self, except in the garden. That is why she commits to gardening so eagerly: because she couldn't bear to see those flowers withered. At the end of the story, she sees her chrysanthemums on the road, thrown away, "a dark speck" as Steinbeck says. They are wasted, just like Elisa's life, love, and happiness.
Foreshadowing is when an author uses symbolism, an event, a small detail, or even a part of dialogue to be a warning or indication of a future event. An author might use this because they want to give the reader knowledge about a future event or to tease them.
In the section "Pathology Indicates Manner of Communication," Snow explains the nature of cholera and argues that the study of the disease will help scientists understand how it spreads and how it can be averted. He combines his knowledge of the characteristics of the disease with his clinical experiences to build his argument.
He continues to build his case through other sections of the essay. For example, in "Cases Proving Person to Person Transmission," he provides evidence from other cases to support his theory that cholera is spread between people. Then, in another section, he maps an outbreak that occurred on Broad Street, connecting the affected individuals to a single water pump. After making these supporting arguments, he arrives at his main argument that cholera spreads through contaminated water.
In sum, Snow discusses a different concept in each section; these sections complement one another to build a complete, effective argument. The section labels help the reader follow Snow's line of thinking by mapping the main points.
The fist book written in American was "The Whole Booke of Psalmes" edited by Richard Mathew, John Eliot, and others.
