<P>During the nineteenth century, tens of thousands of Chinese men and women crossed the Pacific to work, trade, and settle in California. Drawn by the gold rush, they brought with them skills and goods and a view of the world that, though still Chinese, was transformed by their long journeys back and forth. They in turn transformed Hong Kong, their main point of embarkation, from a struggling, infant colony into a prosperous, international port and the cultural center of a far-ranging Chinese diaspora.</P><P>Making use of extensive research in archives around the world, <i>Pacific Crossing</i> charts the rise of Chinese Gold Mountain firms engaged in all kinds of trans-Pacific trade, especially the lucrative export of prepared opium and other luxury goods. Challenging the traditional view that this migration was primarily a "coolie trade," Elizabeth Sinn uncovers leadership and agency among the many Chinese who made the crossing. In presenting Hong Kong as an "in-between place" of repeated journeys and continuous movement, Sinn also offers a fresh view of the British colony and a new paradigm for migration studies.</P>
