Halley’s third logbook

I said at the start of this Channel voyage that I wouldn’t be live-tweeting the logbook as I’d done for Halley’s two Atlantic voyages, as I felt the high proportion of technical data would be of little interest to the general reader. That was a pity as the third logbook is the only one handwritten by Halley, and so from that point of view it’s an interesting document.

In fact I did tweet a few entries at the start of the voyage and I’m doing so again now at the end as these entries contain more general information – but to give you a flavour of the main substance of the log, here’s a typical entry in which Halley records soundings and the times and lunar positions of the tides:

[Sat, June 21] about 9h in the Morn I weighd and stood off to Sea, with a gentle gale of ENE wind, and about One after noon came to an anker in 18 fath. the Ness Light baring NNW; and Calis cliff ENE. here the westward tide was done at 5h.35′, or three hours and half before the Moons Southing. whence I concluded the course of the Tides here the same as at the Ness. viz that a II½ Moon ends the Eastern Tide. at 6h I weighd and stood to the eastward with a small gale of SSW wind, and about 9h fell with the West end of the Riprapps which is a narrow rigd of soft sand. I crost it severall times in 9, 8 and 7 fath and the Eastern tide being near done, I came to an anker in that depth the Ness light baring WNW and that of the South Foreland NbE p[er] Compass. here I rode two tides and found the Eastern tide done on a SW or NE Moon nearest. that it flowed about three fath. that it runs half tide here as by the Shore and that the Sett of the Stream is nearest NE and SW.

We’ll consider the purpose of this data when we look at the results of the voyage, but in this post I want to focus on what I like to call The Mystery of Halley’s Clerks.

Now that remark may excite expectations that this post will struggle to satisfy for this is not a tale of clerks going to sea and mysteriously disappearing, but rather a puzzle about what exactly the clerks did on the voyages – why, for example, was the third logbook written up by Halley and not by his clerk?

The clerk on the third voyage was one Richard Pinfold, who was the only person besides Halley to sail on all three voyages. On the two Atlantic voyages Pinfold was listed as captain’s servant, but on the third voyage he was said to have been captain’s clerk, and so I wondered whether he might have been a servant in Halley’s own household and been promoted to clerk as a ‘reward’ for going on the first two voyages, with Halley effectively covering the job himself. However, the manuscript pay and muster books show that Pinfold was actually entered as gunner’s mate and that the post of captain’s clerk was later interposed in the pay book beneath gunner’s mate. Pinfold was paid a salary as both gunner’s mate (£5 8s 6d) and captain’s clerk (£1 12s 11d), and the small wage paid to him as clerk suggests he performed that job for only a short time, and we know he wrote neither the logbook nor Halley’s letters.

The logs of the two Atlantic voyages weren’t written up by Halley, so they must’ve been written up by his clerks… well, possibly, but possibly not. There’s no immediate reason to doubt that the log of the first voyage was written by the clerk, Caleb Harmon, but the log of the second voyage is more of a puzzle. Halley wrote all his own letters to the Admiralty on both voyages, except for two on the second, and you might expect these to have been written by the clerk, William Curtiss, but they are in a different hand from that of the logbook. My first thought was that Curtiss perhaps fell ill with the “Barbadoes desease” at the same time as Halley, and so another crew member wrote them – but the two rogue letters (which are in the same hand) were written on 30 March and 8 July, either side of the period of sickness in late May, and the July letter states specifically that “we are a very healthy ship” at present. Why then did someone else write the letters, more than three months apart, and why did that person not receive extra pay as Pinfold did on the third voyage? Or why did Curtiss write the letters but not then the logbook?

The person who wrote the first logbook isn’t straightforward either. From the start of this project I’d been surprised at how neat and uniform the logs were and wondered whether they’d actually been written during the voyage or after the ship’s return to London, but then found that other logbooks were similarly neat and so thought that clerks might make draft notes and then write them up neatly while at anchor or in calm seas.

The idea of draft notes fits with a comment made by Alexander Dalrymple in an advertisement for his 1773 publication of Halley’s two Atlantic logs that

The Journal of Dr. Halley’s first Voyage is written on sundry scraps of paper, and some parts repeated in different places, and so blended that it was a very difficult matter to make it out intelligibly…

Dalrymple, who borrowed (and seemingly failed to return) these “scraps of paper” from the Board of Longitude, doesn’t mention whether the handwriting on the scraps was Halley’s or someone else’s, which is a pity as that might tell us something about how that logbook was compiled. A further curiosity is that Dalrymple seems to have been unaware of the existence of fair copies of the two logbooks (now in the British Library), and his published version of the second log was evidently compiled from another source, as there are discrepancies between the two. So what was the source for the second log used by Dalrymple, and who wrote it? And when were the fair copies of the two journals written?

These “sundry scraps of paper” also suggest a new spin on the warning given to Halley by Josiah Burchett at the end of the second voyage. Burchett wrote to Halley in Deptford, giving him permission to leave his ship to call on their lordships in London, “only lett mee give you this Caution, To have ye Books in readinesse”. Now I’d previously assumed this warning was intended to help Halley overcome the misgivings felt by some of their lordships about his handling of the prematurely-terminated first voyage* by making sure he was properly prepared when he met them, but now I wonder if it instead implies that Halley had previously displeased their lordships by returning from that voyage with only “scraps of paper” for his journal, and only had it written up on his return.

So while I think the mysteries surrounding Halley’s clerks might not rival And Then There Were None for excitement, they certainly seem to form a Problem at Sea.

Halley writes from Dartmouth

On 23 August, Halley followed up his 29 July letter informing Burchett of his activities in the eastern part of the Channel with a report of his work in the western section. We learn that Halley continued to be hampered by the weather, but what I particularly like is that the letter provides another instance of Halley showing concern for his men by noting that the continual weighing of anchor was hard physical labour for an under-manned crew.

Honoured Sr

By my last of July 29 from Spitthead I gave you an account that I had carefully observed the Course of the Tides in the Eastern part of the Channell of England; Since then I have lost no opportunity, in order to do the like for the Western part, and I have ankered all along the English Coast in the Offing as far as the Lizard, and from thence inn the midd Channell, and over to Ushant, where I was the last week. The frequent weighing ankers in so deep water has been very hard service to my small company, but the greatest difficulty I find, is from the frequent gales of Wind, which, (especially without the Start) raise the Sea to that degree that there is no riding, and which, in this month of August, have forced me four severall times into Harbour. I waite here for an opportunity of smooth weather, to anker in severall places between the Start and the Sept Isles; wherby I shall be able to compleat the Sett of observations necessary to the description of the Tides in the Offing; of which I cannot find any of our books to give a tollerable account. When I return from the French coast, I entend to putt in to Spitthead, to receive any farther orders their Lopps may think proper for me. With my humble duty to their Lopps I remain

Halley writes from the Downs

As we saw in my last post, Halley had a lot of trouble recruiting his complement of 25 men and by the morning of 14 June his crew numbered just 15 men, and it was only the arrival of a further four that enabled him to sail from Deptford that afternoon.

He arrived in the Downs on 16 June and two days later he sent a short letter to Josiah Burchett, Secretary to the Admiralty, advising him of his arrival and that he expected to receive the four men that their lordships had ordered to be discharged to him during that night.

This brought his crew to 23 men, which included Halley, his surgeon (a man Halley had specifically requested), his clerk*, a cook (one Thomas Cook, natch), and five servants. Let’s hope that the cook – the only time someone was so-designated on any of Halley’s voyages – kept the regular seamen well-fed!

Halley refers to his sailing instructions in his letter, and we’ll take a look at those in my next post.

Able seamen wanted!

When Halley’s first voyage ended prematurely with his return to England to court martial his lieutenant, he had to use all his diplomatic skills to persuade the Lords of the Admiralty to allow him a second attempt. That second voyage, however, was deemed so successful that their lordships lost no time in approving his next proposal for an expedition to survey the tides of the Channel.

This proposal was dated 23 April 1701 and it was evidently approved almost immediately, as on the 26th Halley wrote again to “humbly entreat my Commission to be dispatcht, in order to gett the Paramore Pink mann’d with such Compliment [sic] as their Lopps shall think fitting”, and his commission as master and commander of the Paramore was issued that day.[1] At the same time, the Admiralty sent an order to the Navy Board to clean and fit out the Paramore for “Channell Service”, and they agreed to all the requests for “Extraordinarys” that Halley had made in his letter, including his suggestion that the crew “cannot be well less than it was last time viz: 25 Men.”[2]

Halley wanted his commission quickly so he could begin recruiting his crew, as he was concerned that seamen were scarce as “no men [were] now offering themselves as usuall at other times.” Halley’s problem was that Royal Navy wages were then lower than those offered by merchant ships: Peter Earle tells us that wages in both the royal and merchant navies were broadly similar during peacetime (about 25 shillings a month for an able seaman), but that merchant wages rose dramatically during war when the competition for men became intense.[3]

In 1701, Europe was gearing up for what we know as the War of the Spanish Succession, and so merchant wages were presumably rising in anticipation of its outbreak. In a letter dated 4 June 1701, Halley complained that “I find my self disappointed in my Mate, who for great wages has been tempted to break his promise to me”, and expressed his concern that “for 40 sh[illings] p[er] month I fear I cannot have a man capable to take charge of my shipp, Marchants [sic] giving now so much to any able Seaman” – so merchant ships were already paying able seamen at a 15 shilling premium.

Halley had great difficulty obtaining his crew, and from the date his project was approved until he set sail nearly two months later, he wrote a series of increasingly desperate letters on the subject to Josiah Burchett, Secretary to the Admiralty.

On 31 May, he asked if “their Lopps shall thinking fitting to spare me but two able Seamen out of four or five of the Ships of Warr”, promising “I will take care to return them where I had them in case the breaking out of a war oblige me to desist from my undertaking.” And in an undated letter (endorsed June), Halley wrote that the Paramore was ready to sail if only he had his complement of men, and so “I beseech you to lay before their Lopps the great difficulty I find to gett them”. On 4 June he requested “leave to have out of the Shipps of Warr, under such restriction as their Lopps please, such men as shall be willing to serve on board me”, and this prompted their lordships to order that “3 Prest Men” on ships in the Downs should be discharged into the Paramore on her arrival, which they amended a few days later to “so many Men as he Shall have occasion of”. Halley sailed from Deptford on June 14 and received four men from ships in the Downs, when he anchored there a few days later.

It’s interesting that Halley writes of men “as shall be willing to serve on board me”, as I’m not sure whether this is simply a piece of naval phraseology or a precaution against the trouble he had on his first voyage with recalcitrant officers – although I am sure that if I were a “prest” seaman, I’d rather be on a scientific cruise in the English Channel with Halley, than part of a crew in the war fleet!

Finally, just to let you know that I’m not intending to tweet the log of his third voyage, as even I can see that a report of his continual anchoring around the Channel doesn’t provide a compelling read (to anyone but myself), although I will tweet the occasional entry.

I’m also in the latter stages of my MA and, alas, have little free time for this blog, but I will not neglect Captain Halley entirely and expect to publish a few short posts during his four month voyage (as well as writing my dissertation about him!).

Return to sea

Welcome back to Halley’s Log!

We left Captain Halley last September, newly returned to London and working on his Atlantic chart of magnetic variation, which he formally presented to the Royal Society on 4 June 1701.

But while Edmond had quickly resumed his old habits of attending Royal Society meetings and discoursing endlessly in coffeehouses, the sea was never far from his mind, and on 23 April 1701 he sent this proposal to the Lords of the Admiralty (remember “Lopps” is Halley’s abbreviation for “Lordshipps”):

It is humbly proposed

That if their Lopps shall think fitting to have an exact account of the Course of the Tides on and about the Coast of England, so taken as at one View to represent the whole; (which will be a work of generall Use to all Shipping, especially such as have occasion to turn to Windward, and wch is wanting towards the compleating the Art of Navigation) there be provided a small Vessell such as their Lopps shall think proper, with all convenient speed, on board of which such an account of the Tides may be taken, as their Lopps shall direct; for which service their Lopps most obedient servant humbly offers himself.

Edm. Halley [1]

Their Lopps did think it fitting to have the course of the tides around the southern coast of England observed and gave the order for a vessel – yes, the Paramore Pink – to be prepared for Halley’s third expedition.

So Captain Halley expects to put back to sea very very soon – there’s just the one small matter of a crew to recruit…

Halley’s Atlantic Chart, part 2: his results

Halley undertook his Atlantic voyages to measure the magnetic variation at sea. Magnetic variation (or declination) is the angle between magnetic and geographic north in a horizontal plane. Halley thought that if a pattern could be observed in the variation, it might offer a way to determine a ship’s longitude at sea. He measured the variation regularly throughout his two voyages and began preparing the presentation of his data as soon as he arrived back in Deptford in September 1700.

Halley is noted for his ability to draw general conclusions from complex data and for his appreciation of visual representation of those conclusions, and he demonstrated both these traits in presenting his data in the form of a sea chart.

The chart – known as his Atlantic Chart – holds an important place in the history of cartography, as it is regarded as the first published chart to represent magnetic declination using what became known as isogonic lines. It was not the first time such lines had been thought of, but the earlier examples were never published and Halley is thought unlikely to have known about them. [1]

We’ll look at the chart and its data in a moment, but first I’d like to highlight some of its decorative features.

IMG_0122 copy - Version 4

To the east of the mysterious birds, we find The Icey Sea with the black-streaked “Mountains of Ice” that Halley and his crew had encountered in February (notice their track passing through it). Neither Halley nor his crew had seen icebergs before and Halley was unsure whether they were floating or grounded.

IMG_0122 copy - Version 8

The track of Halley’s second voyage is shown on the chart and indicated by representations of the Paramore pursuing her figure-of-eight course.

IMG_0122 copy - Version 5

There are three cartouches on the chart: the one on South America is formed by a native family reclining beneath two fruit-laden palm trees. The adults wear feathered headdresses and skirts, the woman clutches a small child and the man holds a spear, has a bow at his feet and a quiver of arrows on his back. Behind them, hanging between the trees, is a sheet bearing the chart’s title:

A New and Correct CHART Shewing the Variations of the COMPASs in the WESTERN & SOUTHERN OCEANS as Observed in ye Year 1700 by his Ma:ties Command by Edm. Halley.

IMG_0122 copy - Version 6

A second cartouche appears on the landmass of Africa and carries the chart’s dedication to William III and is topped by personifications of astronomy (holding a telescope and armillary sphere), navigation (a backstaff and ship) and mathematics (dividers and triangle).

The third cartouche is found on North America and explains the information depicted in the chart:

The Curve Lines which are drawn over the Seas in this Chart, do shew at one View all the places where the Variation of the Compass is the same; The Numbers to them, shew how many degrees the Needle declines either Eastwards or Westwards from the true North; and the Double Line passing near Bermudas and the Cape de Virde Isles is that where the Needle stands true, without Variation.

And here’s the full chart, shown with the permission of the Royal Geographical Society:

Halley's Atlantic Chart (© Royal Geographical Society (with IBG), Image S)

You can see that it has two compass roses, the one in the mid-Atlantic radiating lines that somewhat obscure Halley’s “Curve Lines” of equal magnetic declination. (Halley himself realised this was a problem and omitted this feature on the World Chart he published around a year later.) It is on a Mercator projection, with lines of latitude and longitude, and the meridian of London, the equator and tropics identified, but no indication of scale.

This version of the chart includes text that was written subsequently by Halley and printed in two strips that could be stuck to the sides of the original chart. It describes how to consult the chart by way of examples, and explains that it has two uses:

  • to enable the mariner to know by how much he needs to adjust his course to take account of the magnetic variation, and
  • to estimate a ship’s longitude at sea, the curve lines running nearly north-south (as off the west cost of Africa) giving “a very good Indication of the Distance of the Land” from the ship

This useful knowledge is obtained by reference to the isogonic lines. They are a little difficult to pick out but you can easily see the double curved line to the right of the central compass, which Halley has named The Line of No Variation (the agonic line) and the curved lines above and right show the degree to which the compass varies west of geographic north, and to the left, east of geographic north (the number of degrees of variation is shown on the horizontal line above The Icey Sea).

As mentioned above, the chart was (and is) regarded as the first (extant) published use of isolines (contour lines), and until the nineteenth century these lines were known as Halleyan lines.

So the chart is impressive and historically important, but how accurate was it? Alan Cook observed that it was “an improvement on anything that had gone before”, [2] but as I wrote in a previous post, the problem with longitude is knowing both where you are and where the place is that you’re heading. Halley’s recorded longitude was often inaccurate and sometimes considerably so: when he was sailing towards St Helena from the east, the longitude value he reported is actually west of the island – and so the degree of variation he thought applied to the east of the island in fact applied to the west.

Similarly the coordinates of islands and land weren’t then accurately known: Cape Horn, for example, is roughly 10° further west on Halley’s chart than we now know it to be, so his lines of variation near that coast must be likewise misplaced. [3] It seems to me that the moral of this exercise is that to devise a chart that helps estimate a ship’s longitude at sea, the deviser needs to have a fairly accurate knowledge of longitude in the first place.

But Halley was alert to the likelihood of error in his chart and in his final paragraph he wrote that:

…all knowing Mariners are desired to lend their Assistance and Informations, towards the perfecting of this useful Work. And if by undoubted Observations it be found in any Part defective, the Notes of it will be received with all grateful Acknowledgment, and the Chart corrected accordingly.

And I think that’s how Halley’s chart was most useful: it was a cartographic innovation from which better and more accurate maps might evolve.

Halley’s Atlantic Chart, part 1: fish or fowl revisited

Over the next two posts we’ll look at the results of Halley’s voyage, which he published in the form of a sea chart. But before we consider his chart in full, I want to pick out one detail which may help to settle the identity of those mysterious creatures that Halley saw in the South Atlantic.

In a previous post we looked at Halley’s descriptions of three animals – two birds and something akin to a whale – that he’d seen in the seas to the north-west of South Georgia, and I summarised his descriptions as follows:

  1. a bird he takes to be a penguin with a black head and back, white breast, and a bill like that of a crow; it swims deep, dives on the ship’s approach, doesn’t appear to fly, and has a neck like a swan
  2. a second bird he also takes to be a penguin, larger than the first, and the colour and size of a “young Cygnett”, it has a bill that hooks downwards, cries like a bittern, and also swims deep, dives on the ship’s approach, doesn’t seem to fly, and has a neck like a swan
  3. an animal thought by the crew to be a seal but which Halley asserts is not. It bends its tail into a bow, has large fins like a shark and a head like a turtle

While researching that post, I wondered if the second bird might have been a petrel (because of the beak) and some readers suggested that too, but the main objection is that almost every image of petrels shows them flying, which Halley says they don’t do (“either not having wings, or else not commonly useing them”).

Another reader suggested they might have been shags and I think these seem more likely as they resemble penguins and have long necks (I’m looking at the Imperial and South Georgia varieties). They do fly, but the proportion of images of them flying is far lower than it is for petrels.

In that earlier post I mentioned there was another piece of information about these birds that appears at the end of the voyage, and it appears in Halley’s chart. There, Halley gives a description of the birds and provides a little more detail:

The Sea in these parts abounds with two sorts of Animalls of a Middle Species between a Bird and a Fish, having necks like Swans and Swimming with their whole Bodyes always under water only putting up their long Necks for Air.

Now it seems to me that “a Middle Species between a Bird and a Fish” is a good way to describe penguins – but happily Halley doesn’t just describe his birds, he depicts them too! Here they are:

IMG_0122 copy - Version 3

Er… oh, well, perhaps they’re not quite my idea of penguins after all. But before I scoff too much at Halley’s illustration, it’s worth remembering that he was trying to describe something he’d never seen before and to people who likewise had never seen such animals before, and so he has to use vocabulary and comparative imagery that were familiar to him and his readers. Additionally, he wasn’t near land when he saw the birds and he hadn’t mentioned seeing any floating ice, so he may only have seen them swimming in the sea, which would have made it very difficult for him to see them properly (have a look at this 36 second film of penguins at sea and you’ll appreciate his difficulty).

If you look closely at the birds, you can see that their beaks are slightly different, and the one on the right has a few tufts on the back of its head, so I wondered if that might have been a type of crested penguin, such as a southern rockhopper?

As to the animal the crew thought was a seal and Halley says is not, what’s curious about that is that he doesn’t call it a whale or whale-like, an animal he would have known – perhaps he was even among the crowd that went to gawp at this poor cetacean stranded in the Thames around 1690. [1]


Broadside, c1690 (© British Museum, Image Z,1.163)

I don’t have any more information about this animal, which Halley’s biographers have suggested might have been a bottlenose whale, a killer whale or a dolphin, although there are problems with each of these identifications – but I have been wondering whether it might have been a Risso’s dolphin? They have a more turtle-like head, a large dorsal fin, and unlike the bottlenose and killer whale are not remarkable in size, something which Halley fails to comment on. An unfamiliar type of dolphin might also explain why Halley doesn’t use the word whale and why the crew think it’s a seal.

But there are three objections to this suggestion: there don’t seem to be many images of them “twisting [their] tayl into a bow” as Halley describes them doing, he may have been outside their range when he saw them, and the sea temperature may have been too cold.

So we haven’t resolved for certain what these creatures were but we have added some new ideas to the list of possibilities. One thing is certain, though, and that’s that no further clues are likely to come from Halley: five months after his return to England, his recollection of these animals was even more confused as we find it minuted that at the Royal Society meeting of 5 February 1701:

Mr Halley said that he saw a kind of Tortoises in the S. of Brazile, having Necks like Swans, and all their bodies under Water. [2]

And for that creature, I think we may need to search among the monsters of medieval cartography, not the seas of the South Atlantic!
