when circumstances will admit of it on many accounts; and am persuaded that unbroken rest not only contributes much towards the health of a ship's company but enables them more readily to exert themselves in cases of sudden emergency.
As it was my wish to proceed to Otaheite without stopping I ordered everybody to be at two-thirds allowance of bread: I also directed the water for drinking to be filtered though dripstones that I had bought at Tenerife for that purpose.
In the evening we passed the south end of Tenerife which is a round lump of land that, from the lowness of the contiguous land, has at a distance the appearance of a separate island. By our run from the bay of Santa Cruz I make the latitude of the south end of Tenerife to be 28 degrees 6 minutes north.
We ran all night towards the south-south-west having the wind at south-east. The next morning we could see nothing of the land. I now made the ship's company acquainted with the intent of the voyage and, having been permitted to hold out this encouragement to them, I gave assurances of the certainty of promotion to everyone whose endeavours should merit it.
The winds for some days after leaving Tenerife were mostly from the southward. Fishing-lines and tackle were distributed amongst the people and some dolphins were caught.
Thursday 17.
On the 17th the wind came round to the north-east and continued steady in that quarter till the 25th on which day at noon we were in 3 degrees 54 minutes north. As the cloudiness of the sky gave us reason to expect much rain we prepared the awnings with hoses for the convenience of saving water, in which we were not disappointed. From this time to our meeting with the south-east tradewind we had much wet weather, the air close and sultry with calms, and light variable winds generally from the southward.
Tuesday 29.
On the 29th there was so heavy a fall of rain that we caught seven hundred gallons of water.
Thursday 31.
On the 31st, latitude at noon 2 degrees 5 minutes north, found a current setting to the north-east at the rate of fourteen miles in the twenty-four hours. The thermometer was at 82 degrees in the shade, and 81½ degrees at the surface of the sea, so that the air and the water were within half a degree of the same temperature. At eight o'clock in the evening we observed a violent rippling in the sea about half a mile to the north-west of us which had very much the appearance of breakers. This I imagine to have been occasioned by a large school (or multitude) of fish as it was exactly in the track the ship had passed, so that if any real shoal had been there we must have seen it at the close of the evening when a careful lookout was always kept. However if it had appeared ahead of us instead of astern I should certainly have tacked to avoid it. To such appearances I attribute the accounts of many shoals within the tropics which cannot be found anywhere but in maps. Our latitude at this time was 2 degrees 8 minutes north and longitude 19 degrees 43 minutes west. The next day we had more of these appearances from the number of schools of fish by which the ship was surrounded.
February. Saturday 2.
This morning we saw a sail to the north-north-west but at too great a distance to distinguish what she was.
Monday 4.
Had very heavy rain during which we nearly filled all our empty water casks. So much wet weather, with the closeness of the air, covered everything with mildew. The ship was aired below with fires and frequently sprinkled with vinegar; and every little interval of dry weather was taken advantage of to open all the hatchways, and clean the ship, and to have all the people's wet things washed and dried.
With this weather and light unsteady winds we advanced but 2½ degrees in twelve days; at the end of which time we were relieved by the south-east tradewind which we fell in with on the 6th at noon in latitude 1 degree 21 minutes north and longitude 20 degrees 42 minutes west.
Thursday 7.
The next afternoon we crossed the equinoctial line in longitude 21 degrees 50 minutes west. The weather became fine and the south-east tradewind was fresh and steady, with which we kept a point free from the wind and got to the southward at a good rate.
The weather continuing dry we put some of our bread in casks, properly prepared for its reception, to preserve it from vermin: this experiment we afterwards found answered exceedingly well.
Saturday 16.
On the 16th at daylight we saw a sail to the southward. The next day we came up with her and found her to be the British Queen, Simon Paul, master, from London, bound to the Cape of Good Hope on the whale-fishery. She sailed from Falmouth the 5th of December, eighteen days before I left Spithead. By this ship I wrote to England. At sunset she was almost out of sight astern.
Monday 18.
In the course of this day's run the variation changed from west to east. According to our observations the true and magnetic meridians coincided in latitude 20 degrees 0 minutes south and longitude 31 degrees 15 minutes west. At noon we were in latitude 20 degrees 44 minutes south and longitude 31 degrees 23 minutes west. In our advances towards the south the wind had gradually veered round to the east and was at this time at east-north-east. The weather after crossing the Line had been fine and clear, but the air so sultry as to occasion great faintness, the quicksilver in the thermometer in the daytime standing at between 81 and 83 degrees, and one time at 85 degrees. In our passage through the northern tropic the air was temperate, the sun having then high south declination and the weather being generally fine till we lost the north-east tradewind; but such a thick haze surrounded the horizon that no object could be seen except at a very small distance. The haze commonly cleared away at sunset and gathered again at sunrise. Between the north-east and south-east tradewinds the calms and rains, if of long continuance, are very liable to produce sickness unless great attention is paid to keeping the ship clean and wholesome by giving all the air possible, drying between decks with fires, and drying and airing the people's clothes and bedding. Besides these precautions we frequently wetted with vinegar, and every evening the pumps were used as ventilators. With these endeavours to secure health we passed the low latitudes without a single complaint.
The currents we met with were by no means regular, nor have I ever found them so in the middle of the ocean. However from the channel to the southward as far as Madeira there is generally a current setting to the south-south-east.
Thursday 21.
On the evening of the 21st a ship was seen in the north-east but at too great a distance to distinguish of what country.
Friday 22.
The next day the wind came round to the north and north-west so that we could no longer consider ourselves in the tradewind. Our latitude at noon was 25 degrees 55 minutes south, longitude 36 degrees 29 minutes west. Variation of the compass three degrees east.
Saturday 23.
Towards night the wind died away and we had some heavy showers of rain of which we profited by saving a ton of good water. The next day we caught a shark and five dolphins.
Tuesday 26.
We bent new sails and made other necessary preparations for encountering the weather that was to be expected in a high latitude. Our latitude at noon was 29 degrees 38 minutes south, longitude 41 degrees 44 minutes west. Variation 7 degrees 13 minutes east. In the afternoon, the wind being westerly and blowing strong in squalls, some butterflies and other insects like what we call horseflies were blown on board of us. No birds were seen except shearwaters. Our distance from the coast of Brazil at
