In the course of this 24 Hours we have had 4 men died of the Flux, viz., John Thompson, Ship's Cook; Benjamin Jordan, Carpenter's Mate; James Nickolson and Archibald Wolf, Seamen; a melancholy proof of the calamitieous situation we are at present in, having hardly well men enough to tend the Sails and look after the Sick, many of whom are so ill that we have not the least hopes of their recovery.

Had it calm all P.M., which at 5 o'clock obliged us to Anchor under the South Point of Princes Island, the said Point bearing South-West by West, distance 2 miles. At 8 o'clock in the A.M. a light breeze sprung up at North, with which we weigh'd and stood out to Sea. At noon Java Head bore South-East by South, distance 2 Leagues, and the West Point of Princes Island North-North-West, distance 5 Leagues; Latitude Observed 6 degrees 45 minutes South. Java Head, from which I take my departure, lies in the Latitude of 6 degrees 49 minutes South, and Longitude 255 degrees 12 minutes West from the Meridian of Greenwich, deduced from several Astronomical Observations made at Batavia by the Reverend Mr. Mohr.*

* The true longitude of Java Head is 254 degrees 49 minutes West.

Tuesday, 15th, January 1771

Batavia to Capetown.

Had variable light airs of wind, with which we could not get under sail until the morning, when we weighed with a light breeze at North-East, which was soon succeeded by a calm.

Monday 7th to Monday 14th, January 1771

 From this day till Monday 14th we were employ'd wooding and watering, being frequently interrupted by heavy rains. Having now compleated both we hoisted in the Long boat, and made ready to put to Sea, having on board a pretty good stock of refreshments, which we purchased of the natives, such as Turtle, Fowls, Fish, two species of Deer, one about as big as a small sheep, the other no bigger than a Rabbit; both sorts eat very well, but are only for present use, as they seldom lived above 24 hours in our possession. We likewise got fruit of several sorts, such as Cocoa Nutts, plantains, Limes, etc. The Trade on our part was carried on chiefly with money (Spanish Dollars); the natives set but little value upon any thing else. Such of our people as had not this Article traded with Old Shirts, etc., at a great disadvantage.

Sunday, 6th, January 1771

[At Anchor. Princes Island, Sunda Strait.]

At 3 o'clock in the P.M. anchor'd under the South-East side of Princes Island in 18 fathoms water, in order to recruite our wood and water, and to procure refreshments for the people, which are now in a much worse state of health than when we left Batavia. After coming to an anchor I went on shore to look at the watering place, and to speak with the Natives, some of whom were upon the Beach. I found the watering place convenient, and the water to all appearance good, Provided proper care is taken in the filling of it. The Natives seemed inclined to supply us with Turtle, Fowls, etc.; Articles that I intended laying in as great a stock as possible for the benefit of the Sick, and to suffer every one to purchase what they pleased for themselves, as I found these people as easy to traffick with as Europeans. In the morning sent the Gunner ashore with some hands to fill water, while others were empboy'd putting the whole to rights, sending on shore Empty Casks, etc. Served Turtle to the Ship's Company. Yesterday was the only Salt meat day they have had since our arrival at Java, which is now near 4 months.

Saturday, 5th, January 1771

Had fresh breezes at South-West, with squally, rainy weather until the evening, when it clear up, and the wind veer'd to South and South-East, with which we stood to the South-West all night. In the morning the wind veer'd to North-East, which was still in our favour; at noon Princes Island bore West 1/2 South, distant 3 Leagues.

Friday, 4th, January 1771

Most part of these 24 hours squally, rainy weather, winds variable between the North-North-West and South-South-West; at 5 p.m. anchor'd in 28 fathoms water, Cracatoa West, distant 3 miles. Some time after the wind veer'd to North-West, with which we got under sail, but the wind dying away we advanced but little to the South-West before noon, at which time Princes Island bore South-West, distance 8 or 9 Leagues.

Thursday, 3rd, January 1771

In the P.M. had it very squally, with heavy showers of rain; at 1/2 past 7 anchor'd in 19 fathoms, Cracatoa Island South-West, distance 3 Leagues. In the morning came to sail, having very squally variable weather; at Noon Cracatoa West 2 Leagues.

Wednesday, 2nd January, 1771

First and middle parts fresh breezes at South-West, and fair the remainder, squally with rain; plying to windward between Cracatoa and the Java shore without gaining anything.

Tuesday, 1st, JANUARY, 1771.

In the P.M. stood over for the Sumatra Shore, having the wind at South-South-West, a fresh breeze, and the current in our favour; but this last shifted and set to the Eastward in the Evening, and obliged us to Anchor in 30 fathoms, under the Islands which lay off Verekens point, which point constitutes the narrowest part of the Straits of Sunda. Here we found the current set to the South-West the most part of the night; at 5 a.m. weigh'd with the wind at North-West, and stood to the South-West between the Island Thwart-the-way and Sumatra; the wind soon after coming to the westward we stood over for the Java Shore. At noon the South point of Peper Bay bore South-West by South, and Anger Point North-East 1/2 East, distant 2 Leagues; tacked and stood to the North-West.
