Established by Freeman Hunt, this well-known general commerce magazine was an encyclopedia of commercial subjects, remarkable for its orderly arrangement of masses of material.  It promised to discuss every subject interesting or useful to the merchant.  The chief subjects were commercial statistics, commercial regulations and treaties, statistics of population, railroads, canals, and roads, mercantile law, and mercantile libraries and associations, the currency, insurance, banking, navigation, U.S and foreign commerce, and biographies of successful merchants.  Francis Wharton, George Tucker, James H. Lanman, J.W. Scott, and George S. Boutwell were among the most valued contributors to the earlier volumes.  The troubles of the United States Bank occupied some space in the early volumes and a series on "The Morals of Trade" by J.N. Bellows ran through the years 1842-43.
