A Voyage Towards the South pole and Around the World/Volume II/Chapter 10
Passage from St Helena to the Western Islands, with a Description of the Island of Ascension and Fernando Noronha.
1775 May
On the 21st in the evening, I took leave of the governor, and repaired on board. Upon my leaving the shore, I was saluted with thirteen guns; and upon my getting under sail, with the Dutton in company, I was saluted with thirteen more; both of which I returned.
After leaving St Helena, the Dutton was ordered to steer N.W. by W. or N.W. by compass, in order to avoid falling in with Ascension; at which island, it was said, an illicit trade was carried on between the officers of the India Company's ships, and some vessels from North America, who, of late years, had frequented the island on pretence of fishing whales or catching turtle, when their real design was to wait the coming of the India ships. In order to prevent their homeward-bound ships from falling in with these smugglers, and to put a stop to this illicit trade, the Dutton was ordered to steer the course above-mentioned, till to the northward of Ascension. I kept company with this ship till the 24th, when, after putting a packet on board her for the Admiralty, we parted: She continuing her course to the N.W., and I steering for Ascension.
In the morning of the 28th I made the island; and the same evening anchored in Cross Bay on the N.W. side, in ten fathoms water, the bottom a fine sand, and half a mile from the shore. The Cross Hill, so called on account of a cross, or flag-staff erected upon it, bore by compass S. 38° E.; and the two extreme points of the bay extended from N.E. to S.W. We remained here till the evening of the 31st, and notwithstanding we had several parties out every night, we got but twenty-four turtle, it being rather too late in the season; however, as they weighed between four or five hundred pounds each, we thought ourselves not ill off. We might have had a plentiful supply of fish in general, especially of that sort called Old Wives, of which I have no where seen such abundance. There were also cavalies, conger eels, and various other sorts; but the catching of any of these was not attended to, the object being turtle. There are abundance of goats, and aquatic birds, such as men-of-war and tropic birds, boobies, etc.
The island of Ascension is about ten miles in length, in the direction of N.W. and S.E., and about five or six in breadth. It shews a surface composed of barren hills and vallies, on the most of which not a shrub or plant is to be seen for several miles, and where we found nothing but stones and sand, or rather flags and ashes; an indubitable sign that the isle, at some remote time, has been destroyed by a volcano, which has thrown up vast heaps of stones, and even hills. Between these heaps of stones we found a smooth even surface, composed of ashes and sand, and very good travelling upon it; but one may as easily walk over broken glass bottles as over the stones. If the foot deceives you, you are sure to be cut or lamed, which happened to some of our people. A high mountain at the S.E. end of the isle seems to be left in its original state, and to have escaped the general destruction. Its soil is a kind of white marl, which yet retains its vegetative qualities, and produceth a kind of purslain, spurge, and one or two grasses. On these the goats subsist, and it is at this part of the isle where they are to be found, as also land-crabs, which are said to be very good.
I was told, that about this part of the isle is some very good land on which might be raised many necessary articles; and some have been at the trouble of sowing turnips and other useful vegetables. I was also told there is a fine spring in a valley which disjoins two hills on the top of the mountain above-mentioned; besides great quantities of fresh water in holes in the rocks, which the person who gave me this information, believed was collected from rains. But these supplies of water can only be of use to the traveller; or to those who may be so unfortunate as to be shipwrecked on the island; which seems to have been the fate of some not long ago, as appeared by the remains of a wreck we found on the N.E. side. By what we could judge, she seemed to have been a vessel of about one hundred and fifty tons burthen.
While we lay in the road, a sloop of about seventy tons burthen came to an anchor by us. She belonged to New York, which place she left in February, and having been to the coast of Guinea with a cargo of goods, was come here to take in turtle to carry to Barbadoes. This was the story which the master, whose name was Greves, was pleased to tell, and which may, in part, be true. But I believe the chief view of his coming here, was the expectation of meeting with some of the India ships. He had been in the island near a week, and had got on board twenty turtle. A sloop, belonging to Bermuda, had sailed but a few days before with one hundred and five on board, which was as many as she could take in; but having turned several more on the different sandy beaches, they had ripped open their bellies, taken out the eggs, and left their carcasses to putrify; an act as inhuman as injurious to those who came after them. Part of the account I have given of the interior parts of this island I received from Captain Greves, who seemed to be a sensible intelligent man, and had been all over it. He sailed in the morning of the same day we did.
Turtle, I am told, are to be found at this isle from January to June. The method of catching them is to have people upon the several sandy bays, to watch their coming on shore to lay their eggs, which is always in the night, and then to turn them on their backs, till there be an opportunity to take them off the next day. It was recommended to us to send a good many men to each beach, where they were to lie quiet till the turtle were ashore, and then rise and turn them at once. This method may be the best when the turtle are numerous; but when there are but few, three or four men are sufficient for the largest beach; and if they keep patroling it, close to the wash of the surf, during the night, by this method they will see all that come ashore, and cause less noise than if there were more of them. It was by this method we caught the most we got; and this is the method by which the Americans take them. Nothing is more certain, than that all the turtle which are found about this island, come here for the sole purpose of laying their eggs; for we met with none but females; and of all those which we caught, not one had any food worth mentioning in its stomach; a sure sign, in my opinion, that they must have been a long time without any; and this may be the reason why the flesh of them is not so good as some I have eat on the coast of New South Wales, which were caught on the spot where they fed.
The watch made 8° 45' difference of longitude between St Helena and Ascension; which, added to 5° 49' the longitude of James Fort in St Helena, gives 14° 34' for the longitude of the Road of Ascension, or 14° 30' for the middle of the island, the latitude of which is 8° S. The lunar observations made by Mr Wales, and reduced to the same point of the island by the watch, gave 14° 28' 30" west longitude.
On the 31st of May, we left Ascension, and steered to the northward with a fine gale at S.E. by E. I had a great desire to visit the island of St Matthew, to settle its situation; but as I found the wind would not let me fetch it, I steered for the island of Fernando de Noronha on the coast of Brazil, in order to determine its longitude, as I could not find this had yet been done. Perhaps I should have performed a more acceptable service to navigation, if I had gone in search of the island of St Paul, and those shoals which are said to lie near the equator, and about the meridian of 20° W.; as neither their situation nor existence are well known. The truth is, I was unwilling to prolong the passage in searching for what I was not sure to find; nor was I willing to give up every object, which might tend to the improvement of navigation or geography, for the sake of getting home a week or a fortnight sooner. It is but seldom that opportunities of this kind offer; and when they do, they are too often neglected.
In our passage to Fernando de Noronha, we had steady fresh gales between the S.E. and E.S.E., attended with fair and clear weather; and as we had the advantage of the moon, a day or night did not pass without making lunar observations for determining our longitude. In this run, the variation of the compass gradually decreased from 11° W., which it was at Ascension., to 1° W., which we found off Fernando de Noronha. This was the mean result of two compasses, one of which gave 1° 37', and the other 23' W.
1775 June
On the 9th of June at noon we made the island of Fernando de Noronha, bearing S.W. by W. 1/2 W., distant six or seven leagues, as we afterwards found by the log. It appeared in detached and peaked hills, the largest of which looked like a church tower or steeple. As we drew near the S.E. part of the isle, we perceived several unconnected sunken rocks lying near a league from the shore, on which the sea broke in a great surf. After standing very near these rocks, we hoisted our colours, and then bore up round the north end of the isle, or rather round a group of little islets; for we could see that the land was divided by narrow channels. There is a strong fort on the one next the main island, where there are several others; all of which seemed to have every advantage that nature can give them, and they are so disposed, as wholly to command all the anchoring and landing-places about the island. We continued to steer round the northern point, till the sandy beaches (before which is the road for shipping) began to appear, and the forts and the peaked hills were open to the westward of the said point. At this time, on a gun being fired from one of the forts, the Portuguese colours were displayed, and the example was followed by all the other forts. As the purpose for which I made the island was now answered, I had no intention to anchor; and therefore, after firing a gun to leeward, we made sail and stood away to the northward with a fine fresh gale at E.S.E. The peaked hill or church tower bore S., 27° W., distant about four or five miles; and from this point of view it leans, or overhangs, to the east. This hill is nearly in the middle of the island, which no where exceeds two leagues in extent, and shews a hilly unequal surface, mostly covered with wood and herbage.
Ulloa says, "This island hath two harbours capable of receiving ships of the greatest burden; one is on the north side, and the other is on the N.W. The former is, in every respect, the principal, both for shelter and capacity, and the goodness of its bottom; but both are exposed to the north and west, though these winds, particularly the north, are periodical, and of no long continuance." He further says, that you anchor in the north harbour (which is no more than what I would call a road) to thirteen fathoms water, one-third of a league from shore, bottom of fine sand; the peaked hill above-mentioned bearing S.W. 2° southerly.*
[* See Don Antonio d'Ulloa's Book, vol. ii. chap. 3. page 95 to 102, where there is a very particular account of this island.]
This road seems to be well sheltered from the south and east winds. One of my seamen had been on board a Dutch India ship, who put in at this isle in her way out in 1770. They were very sickly, and in want of refreshments and water. The Portuguese supplied them with some buffaloes and fowls; and they watered behind one of the beaches in a little pool, which was hardly big enough to dip a bucket in. By reducing the observed latitude at noon to the peaked hill, its latitude will be 3° 53' S.; and its longitude, by the watch, carried on from St Helena, is 32° 34' W.; and by observations of the sun and moon, made before and after we made the Isle, and reduced to it by the watch, 32° 44' 30" W. This was the mean result of my observations. The results of those made by Mr Wales, which were more numerous, gave 32° 23'. The mean of the two will be pretty near the watch, and probably nearest the truth. By knowing the longitude of this isle, we are able to determine that of the adjacent east coast of Brazil; which, according to the modern charts, lies about sixty or seventy leagues more to the west. We might very safely have trusted to these charts, especially the variation chart for 1744, and Mr Dalrymple's of the southern Atlantic ocean*.
[* Ulloa says, that the chart places this island sixty leagues from the coast of Brazil; and that the Portuguese pilots, who often make the voyage, judge it to be eighty leagues; but, by taking the mean between the two opinions, the distance may be fixed at seventy leagues.]
On the 11th, at three o'clock in the afternoon, we crossed the equator in the longitude of 32° 14' W. We had fresh gales at E.S.E., blowing in squalls, attended by showers of rain, that continued at certain intervals, till noon the next day, after which we had twenty-four hours fair weather.
At noon on the 13th, being in the latitude of 3° 49' N., longitude 31° 47' W., the wind became variable, between the N.E. and S.; and we had light airs and squalls by turns, attended by hard showers of rain, and for the most part dark gloomy weather, which continued till the evening of the 15th, when, in the latitude of 5° 47' N., longitude 31° W., we had three calm days, in which time we did not advance above ten or twelve leagues to the north. We had fair weather and rain by turns; the sky, for the most part, being obscured, and sometimes by heavy dense clouds which broke in excessive hard showers.
At seven o'clock in the evening on the 18th, the calm was succeeded by a breeze at east, which the next day increasing and veering to and fixing at N.E., we stretched to N.W. with our tacks on board. We made no doubt that we had now got the N.E. trade-wind, as it was attended with fair weather, except now and then some light showers of rain; and as we advanced to the north the wind increased, and blew a fresh top-gallant gale.
On the 21st, I ordered the still to be fitted to the largest copper, which held about sixty-four gallons. The fire was lighted at four o'clock in the morning, and at six the still began to run. It was continued till six o'clock in the evening; in which time we obtained thirty-two gallons of fresh water, at the expence of one bushel and a half of coals; which was about three-fourths of a bushel more than was necessary to have boiled the ship's company's victuals only; but the expence of fuel was no object with me. The victuals were dressed in the small copper, the other being applied wholly to the still; and every method was made use of to obtain from it the greatest quantity of fresh water possible; as this was my sole motive for setting it to work. The mercury in the thermometer at noon was eighty-four and a half, and higher it is seldom found at sea. Had it been lower, more water, under the same circumstances, would undoubtedly have been produced; for the colder the air is, the cooler you can keep the still, which will condense the steam the faster. Upon the whole, this is an useful invention; but I would advise no man to trust wholly to it. For although you may, provided you have plenty of fuel and good coppers, obtain as much water as will support life, you cannot, with all your efforts, obtain sufficient to support health, in hot climates especially, where it is the most wanting: For I am well convinced, that nothing contributes more to the health of seamen, than having plenty of water.
The wind now remained invariably fixed at N.E. and E.N.E., and blew fresh with squalls, attended with showers of rain, and the sky for the most part cloudy. On the 25th, in the latitude of 16° 12' N., longitude 37° 20' W., seeing a ship to windward steering down upon us, we shortened sail in order to speak with her; but finding she was Dutch by her colours, we made sail again and left her to pursue her course, which we supposed was to some of the Dutch settlements in the West Indies. In the latitude of 20° N., longitude 39° 45' W., the wind began to veer to E. by N. and E.; but the weather remained the same; that is, we continued to have it clear and cloudy by turns, with light squalls and showers. Our track was between N.W. by N. and N.N.W., till noon on the 28th, after which our course made good was N. by W., being at this time in the latitude of 21° 21' N., longitude 40° 6' W. Afterwards, the wind began to blow a little more steady, and was attended with fair and clear weather. At two o'clock in the morning of the 30th, being in the latitude of 24° 20' N., longitude 40° 47' W., a ship, steering to the westward, passed us within hail. We judged her to be English, as they answered us in that language; but we could not understand what they said, and they were presently out of sight.
In the latitude of 29° 30', longitude 41° 30', the wind slackened and veered more to the S.E. We now began to see some of that sea-plant, which is commonly called gulph-weed, from a supposition that it comes from the Gulph of Florida. Indeed, for aught I know to the contrary, it may be a fact; but it seems not necessary, as it is certainly a plant which vegetates at sea. We continued to see it, but always in small pieces, till we reached the latitude 36°, longitude 39° W., beyond which situation no more appeared.
1775 July
On the 5th of July, in the latitude of 22° 31' 30" N., longitude 40° 29' W., the wind veered to the east, and blew very faint: The next day it was calm; the two following days we had variable light airs and calms by turns; and, at length, on the 9th, having fixed at S.S.W., it increased to a fresh gale, with which we steered first N.E. and then E.N.E., with a view of making some of the Azores, or Western Isles. On the 11th, in the latitude of 36° 45' N., longitude 36° 45' W., we saw a sail which was steering to the west; and the next day we saw three more.
