This book presents studies of ten great commodities which occupy an important place in the economic life of the United States and in the international trade of the world. Originally appearing in Commerce Monthly, a journal of commerce and finance published by the National Bank of Commerce in New York, these studies occasioned so much interest that they have been made the subject of more elaborate investigations which are now presented here in permanent form..... Many of the earliest books, particularly those dating back to the 1900's and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.
