Chapter 3 of The Great Gatsby is particularly filled with symbols of wealth, opulence and wastefulness. Some of these symbols are very subtle in their suggestiveness. Gatsby has a Rolls-Royce, perhaps the most famous luxury brand of car in the world, but also an English car rather than an American limousine. Gatsby fetishes England, partly because its antiquity trumps the old money of East Egg, but also because it is safely distant. Oxford is a lot older than Yale, but Gatsby can also pretend to have been educated at Oxford with impunity: if he claimed to have gone to Yale, Nick and Tom would both know he was lying. The Rolls-Royce symbolizes not only Gatsby's wealth, but his aspirations.
The crates of oranges and lemons are equally symbolic. To have five crates of them delivered from New York every Friday is an extravagant gesture, and the bright orange and yellow fruits must be as beautiful as flowers. On Monday, they are nothing but pith and skin, as empty and lifeless as the hungover party guests probably feel. In the meantime, they have had all the juice squeezed out of them, rather as Gatsby's false friends have bled him dry. The fact that the party, like all parties, never lives up to the anticipation is symbolized by the tedious repetitiveness of the butler having to operate the juicing machine two hundred times in half an hour.
The same care is taken with many other symbols in the chapter. Gatsby's library, for instance, is like him: a fake, but a thorough and partly convincing fake, the type of fake, in fact, which makes one question the genuineness of the real thing. The library is panelled with carved English oak, which may come from a real English library, but was "probably transported complete from some ruin overseas." The books are real books, not merely leather spines glued onto shelves. That sort of cheap sham would be beneath Gatsby. On the other hand, Gatsby has never read the books, as the pages remain uncut. In any case, they are the type of books no one ever reads: Stoddard's Lectures. Gatsby has purchased rows of worthy, classic, leather-bound books to fill the shelves of his faux gothic library, creating an approximate simulation of the type of library old families and colleges build up over centuries. This, like his gigantic new house, is a symbol of Gatsby and his approach to life.
