Cannery Row The Pearl of Cannery Row A pearl is created when a tiny speck of intruding dust enters and irritates an oyster shell. The reaction of the oyster is to make a beautiful pearl out of the particle of dust. Some pearls are perfect and others are imperfect, but all are a unique and wondrous creation of nature. In Cannery Row, John Steinbeck imitates nature’s process with Cannery Row as the oyster and Mack as the speck of dust. Steinbeck shows Mack as the irritant which causes Cannery Row to veer from a precarious course and make a change for the better.
