According to the professional reviews, the major strength of this publication by Brian Rouleau is that the author has not limited the scope of his research to either Atlantic or Pacific. He rather sets out to perform the examination of the global maritime empire. This new volume forces the readers to reconsider the ways in which the foreign relations are working. The author of the book has professionally crafted a truly impressive reimagining of the working-class seamen placing them at the centre of the American relationship with the other world in the early and mid-XIX century. The straightforward arguments and imaginative research conducted by the author has made this publication an uncommonly pleasant reading. The efforts made by Rouleau has eventually resulted in this groundbreaking study of the American sailors abroad; in this volume, he has rewritten the whole history of the foreign relations of the United States in the antebellum are. One of the point revealed by the author was that the Manifest Density was the global process extending quite far beyond the terrestrial borders of America, and he has done this through a very keen analysis and impressively thorough research. The content of the volume is illustrating a very wide range of the inter-cultural encounters between the seafarers and the people who they met all around the globe.
