Saturday, 29th. Fresh Breezes and pleasant weather. Variation of the Compass 2 degrees 25 minutes West. Wind East-South-East; course South by West; distance 101 miles; latitude 5 degrees 25 minutes South, longitude 32 degrees 48" West.
Sunday, 30th. A Steady breeze, and for the most part close cloudy weather. Variation by several Azimuths 1 degree 31 minutes West. At noon the observed latitude 7 miles southward of account. Wind East-South-East; course South ¾ West; distance 107 miles; latitude 7 degrees 8 minutes South, longitude 33 degrees 4 minutes West.
Monday, 31st. A Fresh breeze and Clear weather. Variation 0 degrees 15 minutes West. Observed Latitude again to the Southward of the Log. Wind East to East-South-East; course, South ½ West; distance 114 miles; latitude 9 degrees 1 minute South, longitude 33 degrees 16 minutes West.
[November 1768. Between Equator and Rio.]
Tuesday, November 1st. Moderate breezes, for the most part Cloudy. Variation by the mean of Several Azimuths 0 degrees 58 minutes West in the Evening, and in the Morning found it to be 0 degrees 18 minutes West. Wind East-South-East; course South ¾ West; distance 98 miles; latitude 10 degrees 38 minutes South.
Wednesday, 2nd. A Steady breeze and fine pleasant weather. This Afternoon, by the mean of Several Azimuths and the Amplitude, found the Variation to be 0 degrees 34 minutes East, from which it appears that about the aforegoing Noon we have Crossed the Line of no Variation in the Latitude of 10 degrees 38 minutes South, and, according to the following Observations, in 32 degrees 0 minutes West longitude from Greenwich. At 5 hours 5 minutes 0 seconds Apparent time a.m. the longitude of the Ship and the Observation of the moon and the star Aldebaran was found to be 32 degrees 0 minutes 45 seconds; at 8 hours 17 minutes 0 seconds, per sun and moon, 32 degrees 25 minutes 0 seconds; and at 9 hours 0 minutes 16 seconds, 32 degrees 19 minutes 0 seconds. The mean of the three is 32 degrees 14 minutes 55 seconds. And again at 7 hours 12 minutes 52 seconds, per sun and moon, 32 degrees 10 minutes 4 seconds; and at 7 hours 19 minutes 42 seconds, per sun and moon, 32 degrees 15 minutes 20 seconds. The mean of these two is 32 degrees 12 minutes 42 seconds, and the mean of the whole is 32 degrees 13 minutes 43 seconds West from Greenwich, which is less by a whole Degree than that by account, which is a Considerable Error to be made in 5 Days in these low Latitudes. One would think from this that we must have had a Current setting to the Eastward, which is not likely that it should set against the settled trade wind. The 3 first of these Observations were made by Mr. Green, and the 2 last by myself. Wind East-South-East, South; course South by West; distance 132 miles; latitude 12 degrees 48 minutes South, longitude 32 degrees 20 minutes West per Observation.
Thursday, 3rd. A Fresh Trade wind and fair weather. Variation per Azimuth this Evening 0 degrees 47 minutes East, and at a little past 9 a.m. longitude in per sun and moon 33 degrees 0 minutes West of Greenwich. Wind East by South-East; course South 15 degrees West; distance 128 miles; latitude 14 degrees 51 minutes South, longitude 33 degrees 7 minutes West.
Friday, 4th. A Steady Gale and fair weather. P.M. Variation per Azimuth 1 degree 29 minutes West, ditto 1 degree 28 minutes West, and by the Amplitude 1 degree 12 minutes West; mean 1 degree 23 minutes West, by which it appears that we have again Crossed the Line of no Variation. At ½ past 9 a.m. the longitude of the Ship, per Observation of the sun and moon, 33 degrees 26 minutes 30 seconds. Wind East by South; course South 19 degrees 30 minutes West; distance 125 miles; latitude 16 degrees 49 minutes South, longitude 33 degrees 37 minutes West.
Saturday, 5th. Fine pleasant weather. Variation per Azimuth this morning 3 degrees 21 minutes East, which makes me Doubtful of the Variation found yesterday, tho' at the time I had not the least room to doubt of the Accuracy of the Observations. Longitude per Observation 34 degrees 43 minutes 30 seconds West. Wind East to North-East; course South 30 degrees 35 minutes West; distance 109 miles; latitude 18 degrees 22 minutes South, longitude 34 degrees 50 minutes West.
Sunday, 6th. First and Latter part squally, with heavy Showers of rain; middle moderate and fair. I now determined to put into Rio de Janeiro in preferance to any other port in Brazil or Falkland Islands, for at this place I knew we could recruit our Stock of Provisions, several Articles of which I found we should in time be in want of, and at the same time procure Live Stock and refreshment for the People; and from the reception former Ships had met with here I doubted not but we should be well received. Wind North-North-East, variable, South; course South 55 degrees West; distance 74 miles; latitude 19 degrees 3 minutes South, longitude 35 degrees 50 minutes West.
Monday, 7th. Moderate breezes and Clear weather. P.M. found the Variation to be 4 degrees 49 minutes East. At 6 Sounded and had 32 fathoms Water; the Bottom Coral Rocks, fine Sand and Shells, which Soundings we carried upon a South-West ½ West Course 9 or 10 leagues, and then had no ground with 100 fathom. We were by our account and per run afterwards 54 Leagues East from the Coast of Brazil and to the Southward of the Shoals called Abrollos, as they are laid down in Most Charts. Wind South-East to North-East; course South 58 degrees West; distance 68 miles; latitude 19 degrees 46 minutes South, longitude 36 degrees 50 minutes West.
Tuesday, 8th. Fresh breezes and Cloudy weather. P.M. variation by the Mean of 12 Azimuths 5 degrees 26 minutes East, and by an Amplitude in the Morning 7 degrees 52 minutes. At 6 a.m. saw the Land of Brazil bearing North-West ½ North, distance 8 or 10 leagues. At 8 Sounded, had 37 fathoms, Coarse Sand, broken Shells, and Coral Rocks. At 9 brought too and Spoke with a Fishing Boat, who informed us that the land in sight lay to the Southward of Santo Espiritu. It appears high and Mountainous; the drawing Number (3) exhibits a View of this Land as it appeared from the Ship (A), being near to Santo Espiritu, and a remarkable hill (B) bore North-West ½ North, distance 7 or 8 leagues. Made Sail in Shore, the wind being Southerly. Had from the above Depth to 14 fathoms the same sort of Bottom. Found the Ship at Noon by Observation 10 Miles to the Southward of account, which I suppose to be occasioned by a Current setting between the South and West. Wind North-North-East, North by West, South-South-West to South by West; course South 50 degrees West; distance 140 miles; latitude 21 degrees 16 minutes South, longitude 37 degrees 35 minutes West.
Wednesday, 9th. First and Latter part Hazey, with a Moderate Breeze; Middle, fresh Gales, with Thunder, Lightning, and rain. At 3 p.m. tack't in 16 fathoms, distance from the Shore 5 Leagues, the land Extending from the North-West by West to North-East. At 5 took the 2nd Reef in the Topsails and got down Topgallant Yards, stood to the South-East until Midnight, then tack'd, Sounding from 16 to 55 fathoms. At 8 a.m. Loosed the Reefs out of the Topsails and got Topgallant Yards a Cross; unstowed the Anchors and bent the Cables. At Noon Latitude Observed 21 degrees 29 minutes South, the Land Extending from South-West by South to North-North-West, distance 4 leagues, Soundings from 55 to 10 fathoms. Wind South-South-East, South-South-West, South; course South 62 degrees 15 minutes West; distance 28 miles; latitude 21 degrees 29 minutes South.
[Nearing Rio Janeiro.]
Thursday, 10th. Moderate breezes and Hazey upon the Land. Stood in for the Shore South-West ½ West. Depth of water from 10 to 9 fathoms and from 9 to 16 fathoms, being then 4 Leagues from the Land. From 16 fathoms it shoalded gradually to 5 fathoms; then we tacked, being about 1½ Leagues from the Shore. The extreams of the Land to the Southward, which we took for Cape St. Thomas, bore South ¾ West, distance 4 leagues. The Land from Cape St. Thomas to the Northward lies North by East ½ East. Along the Shore is low land covered with Wood and Sandy Beaches, but inland are very high Mountains, the greatest part of them being hid in the Clouds. Stood off until 5 in the Morning East and East by South. Depth of Water 10, 20, 16, 23, and 30 fathoms. At Noon Latitude Observed 21 degrees 30 minutes; Depth of Water 14 fathoms; Grey sand with black Specks. Extreams of the Land from South-West by West to North-North-West; distance 12 or 14 leagues. Wind South-South-East, South-East by South, South by East; course East ¼ South; distance 17 miles; latitude 21 degrees 30 minutes South, longitude 37 degrees 43 minutes West per account.
