amount of the average trade to China at near 4,000,000 

 Roubles. 



By taking therefore the medlutn between that fum and 481,460, the 

 amount of the duties in 1777, the average fum of the duties will be 

 515,730; and, as the duties in 1777 make nearly a fixth of the whole 

 fum of exportation and importation, by multiplying 515,730 by 6, we 

 have the grofs amount of the average exports and imports at 3,094,380. 

 But as feveral goods pay no duty, and as the contraband trade according 

 to the loweft valuation is eftimated at the fifth part of the exports and 

 imports ; the grofs amount of the average trade to China may be fairly 

 computed at near ^,000,000. the fum ftated above.
