LETTER from an officer on board 
the Congress , United States Frigate , 
dated Bay of Canton , Bee. 26, 1819, 
on the restraints laid on Foreigners 
in their Commercial transactions with 
the Chinese. 
E arrived in this country on the 
1st of Nov. I have now seen 
Canton, the great entrepot of oriental 
commerce, and, like other voyagers who 
give the reins to imagination rather 
than reason, I find the reality inade¬ 
quate to the ideas I had formed of the 
archetype. Nor, indeed, has our recep¬ 
tion been attended with very flattering 
circumstances. The Chinese regard with 
singular aversion, every appearance of 
military. They beheld, with alarm 
and jealousy, the arrival of a ship of 
war. To us they have manifested the 
most marked animosity. They ordered 
us to move to a distance, refused us the 
services of a compreclor , a person de¬ 
puted to supply the ship with provi¬ 
sions. When our commander, Capt. 
Henley, repaired to Canton, he received 
an order to depart, but when they 
found we treated their conduct with 
the contempt it merited, and that Capt. 
Henley persisted in his demand of a 
compredor , they began,after many weeks 
delay, to grant us, with a good grace, 
the authorization required. Without 
particularising all the details of tlieir 
absurd and ridiculous conduct, in every 
thing relative to the vessel, suffice it to 
say, that nothing was left unattempted 
to thwart our views, and make our stay 
here insupportable. 
Foreign commerce is managed, at 
Canton, by eleven persons, who form 
what is called the Hong or the counting- 
house
