High & Mountainous & forms several Bays & inlets. SW½S.14 Leagues from the Cape of good Success & 2 or 3 Leagues from the Shore lies New Island it is 2 Leagues in length NE & SW. the NE end is terminated by a remarkable Hillick. SW 7 Leagues from New Island lies the Isle Evouts. & South a little Westerly from this Island lies Barnevalt two small flatt Island close to Each other, they are partly Environ'd with rocks of Diff.t height above water & lay SW 24 Leagues
from Strait Le Mair, from Barnevalt Island to the SEt point of Hermites Island is SW b S distce. 3 Leagues, these Islands lay Et & NW, & are Pretty high and will from most Points of View betaken for one Island, or a Part of the Main. from the SEt Hermites Isles to Cape Horn the Course is SW B S dist 3 Leagues - The Appearance of this Cape & Hermites Islands is represented in the last View in the Chart which I have drawn of this Coast from our First making the land unto Cape Horn in which is included Strait Le Mair & Part of Staten Land, in this chart I have laid down no land nor figured out any Shore but what I saw myself.& thus for the Chart may be depended upon the Bay & inlets are left voide, the openings of which we only see from the Ship it cannot be doubted but what there is Anchorage ,Wod, & Water in those Bays & it must have been in some of them that the Dutch Squadron commanded by Hermites put into in the Year 1624 it was the Vice Admiral chapar.... of this Squadron who first discover'd that the land of Cape Horn was consisted of a Number of Islands. but the account they have given of these parts is very short & imperfect & that of Sch..ton & Le Maire still worse. that it is no wonder that the Charts hither to Published should be found incorrect not only in laying down the Sand but in the Latitude. & Longitude of the Places they contain. but I can now venture to Assert that the Longitude of few parts of the World are better Assertained than that of Strait Le Maire & Cape Horn be determd.by several Observations of the Sun & Moon, made both by my self & by Mr Green the Astronomer-
We found the Variation of the Compass on this Coast to be from 23º to 25º East, except near Barnevalts Islands and Cape Horn where we found it less and unsettled, it is likely that it is here disturbed by the land. as the Dutch Squadron before mentioned found in this very place all their Compasses to differ from each other. The declination of the South point of the Dipping Needle when set up ashore in Success Bay was below the Horizon, between Strait Le Maire and Cape Horn we found a Current setting generally pretty strong to the NEt when we were in with the Shore, but when 15 or 20 Leagues off we were, not Sensible of any.
Remarkable Occurrences in January 1769 South Seas-

PM the weather clearing up a little saw Cape Horn bearing WSW dist.ce about 6 Lg's & from which I take my departure, its Latitude & Longitude have before been taken notice of -
