The Pereseverance proceeded on her voyage towards Canton, and arrived at the Sandwich Islands on the 8th of September, where we took in fresh provisions and water, and sailed again on the 30th. There are several islets and rock, which lie directly in the track of vessels bound from the Sandwich Islands to Canton, that are very dangerous if fallen in with in the night ; two of which were discovered by captain Wake, and are called Wake's Island and Rocks. I did not fail in with them, but having received their latitude and longitude from a friend, I will here insert it for the information of those who may be bound on this voyage, although I do not accountable for its being correct. The latitude of Wake's Island is 19° 00' north, and the longitude 193° 12' west. Wake's Rocks are in latitude 17° 48' north, and in longitude 186° 12' west.
