What is an example of imagery in the novel, The Witches of New York?

Imagery:

“New York had become a city of astonishments. Wonders and marvels came so frequent and fast, a day without spectacle was cause for concern. Men involved themselves with the business of making miracles. Men in starched collars and suits, men in wool caps and dirty boots. From courtrooms to boardrooms to the newsrooms of Park Row; from dockyards to scaffolds to Mr. Roebling’s Great Bridge—every man to a one had a head full of schemes: to erect a monument to genius, to become a wizard of invention, to discover the unknown. They set their sights on greatness while setting their watches to the noontime drop of the Western Union Time Ball. Their dreams no longer came to them via stardust and angels’ wings, but by tug, train, and telegraph. Sleep lost all meaning now that Time was in man’s grasp” (3).
