The register of outstanding tonnage of steam vessels exhibits a much 

 larger amount than is given above; but many of the vessels still re- 

 tained on the register are known to be lost or out of service. The ac- 

 tual existing tonnage in service is given in the above table.

Lake trade of the United States (from the Patent Office Report 

 1850-1— M^recw?." p. 531.) 



The following table affords a good idea of the magnitude of a por- 

 tion of the internal trade of the United States. The aggregate valua- 

 tion of our lake trade for the year 1850 (imports and exports) amounts 

 to the large sum of $186,484,905; or more, by $40,000,000, than the 

 whole foreign export trade of the country. The aggregate tonnage 

 employed on the lakes of the United States is equal to 203,041 

 tons, of which 167,137 tons is American, and 35,904 tons British. 



The commerce of Lakes Erie, Huron, Michigan, Ontario, Cham- 

 plain, and St. Clair, is as follows :
