We fell in with this Coast 21 Leagues to the Westward of Straits Le Mair, and ranged the coast from thence to the Strait within 2 or 3 Leagues of the Land, and had soundings all the way from 40 to 20 fathoms, a Gravelly and Sandy Bottom. The land near the Shore is in general low but hilly, the face of the Country appears Green and Woody, but in land are Craggy Mountains; they appeared to be of no great height, nor were they Covered with Snow. The most remarkable land on Terra Del Fuego is a high Mountain in form of a Sugar Loaf, situated not far from the sea on the South-West side of the Land, and 3 hills called the 3 Brothers. They lay near the Shore and nine Miles to the Westward of Cape St. Diego, which is a low point that forms the North-West Entrance of Strait Le Mair, and are Contiguous to Each other. The Sugar Loaf lies from these Hills South-South-West, and when it was in this situation the Appearances of the Land is represented in the first View in the Chart, but it must be observed that from this point of View the Three Brothers appear far more Conspicuous than from any other; these land Marks are by some Voyagers thought very necessary to know Strait Le Mair by, but whoever coasts Terra Del Fuego within sight of land cannot possibly miss the Strait, it being of itself so very Conspicuous; and Staten Land, which forms the East side, is still more so from its very rugged appearance. One League and a half to the Westward of Cape St. Diego lies Cape St. Vincent, between these two Capes lies Vincent's Bay,* (* Now called Thetis Bay, it is a very poor anchorage.) a Small Cove wherein is Wood and Water, and before which a Ship might Anchor with a Southerly or South-West wind, but the ground is none of the best, unless you go into the very Mouth of the Cove, which is on the East side of the first Bluff point from Cape St. Vincent, where there is Anchorage in 4 fathoms, a Sandy Bottom. In going in keep clear of the Sea Weed, and send a Boat Ahead to sound, and at best this is but a bad place for Shipping, and only recommended to such as are in want of Wood and Water, and have no Opportunity to put into the Strait, which in Prudence ought not to be attempted but with a fair wind or Moderate weather, and upon the very first of the Tide of Flood, which hapens here at the full and Change of the Moon about 1 or 2 o'clock, and then to keep as near to Terra Del Fuego Shore as the winds will permit. By using these Precautions you will be sure of either getting quite through the Straits in one Tide or to the Southward of Success Bay; and it may be more Prudent to put in there should the wind be Southerly, than to attempt to weather Staten Land with a Lee Wind and Current, for I believe this to be the Chief reason why Ships have run a Risk of being drove on that Island.
