«At five in the afternoon we described two small islands, at the distance of four leagues to the westward; one was called Hoonga Hapaee, and the other Hoonga [Page 187] Tonga. They are situated in the latitude of 20° 36′ south, about ten leagues from the western point of Annamooka. According to the information of two islanders who had been sent on board by Feenou as pilots, only five men resided on Hoonga Hapaee, and Hoonga Tonga had no inhabitants.»
