At Tumai is a burial-ground for the citizens of the United States, where their graves and tombs shall not be molested.

The government of Loo-Choo shall appoint skilful pilots, who shall be on the lookout for ships appearing off the island, and if one is seen coming toward Napa, they shall go out in good boats beyond the reefs to conduct her into a secure anchorage, for which service the captain shall pay the pilot, five dollars; and the same for going out of the harbor beyond the reefs.

Whenever ships anchor at Napa, the local authorities shall furnish them with wood at the rate of three thousand six hundred copper cash per thousand catties; and with water at the rate of six hundred copper cash (forty-three cents) for one thousand catties, or six barrels full, each containing thirty American gallons.
