 year, commencing January 1, 1804, and ending December 31, 1876, with gross valuation

 ported which is not credited to any port. Assuming the exportation of whale-oil for that period at 

 one-third of the importation, and the exportation of bone at two-thirds of the importation, it is neces- 

 sary to add to the former 9,226,834 gallons, and to the htter 206,551 pounds.
