Captain Cook in Google Earth: Fevers and Fluxes

leave a comment »

His Majesty’s Bark Endeavour arrived in Batavia, Java, on 10th October, 1771. At this point in the voyage, more than 3 years after setting sail from Plymouth, the ship was in a very poor state and in need of a major refit. John Satterly, the ship’s carpenter provided Lieutenant Cook with a description of her defects, the majority of the damage being inflicted when Endeavour ran aground on a reef off Australia:

The ship very leaky (as she makes from 12 to 6 inches water per hour) occasioned by her main Kiel being wounded in many places and the Scarfe of her Stem being very open. The false Kiel gone beyond the Midships from Forward and perhaps further, as I had no opportunity of seeing for the water when hauled ashore for repair. Wounded on her Starboard side under the Main Chains, where I imagine is the greatest leaks (but could not come at it for the water).

By contrast, the men in were in good condition. The diet of his crew was constantly on Cook’s mind and he made every effort to procure fresh produce whenever possible. His journal entry for 15Oct1771 reads:

Monday, 15th. Fresh Sea and land breezes and fair weather. I had forgot to mention that upon our arrival here I had not one man upon the sick list; Lieut. Hicks, Mr. Green, and Tupia were the only people that had any complaints occasioned by a long continuance at Sea.

This was a great success considering the hardships, both physical and psychological, the men had endured. However, a mere 3 weeks after returning to ‘civilisation’ from the privations that attended their voyage of discovery the picture was very different. On Wednesday, 07Oct1771 Cook wrote:

Wednesday, 7th. Employ’d getting ready to heave down in the P.M. We had the misfortune to lose Mr. Monkhouse, the Surgeon, who died at Batavia of a Fever after a short illness, of which disease, and others, several of our people are daily taken ill, which will make his loss be the more severely felt; he was succeeded by Mr. Perry, his mate, who is equally as well skilled in his profession.

And another 3 weeks after this:

Wednesday, 26th. The number of Sick on board at this time amounts to 40 or upwards, and the rest of the Ship’s Company are in a weakly condition, having been every one sick except the Sailmaker, and old Man about 70 or 80 years of age. But notwithstanding this general sickness, we lost but 7 men in the whole: the Surgeon, 3 Seamen, Mr. Green’s servant, and Tupia and his servant, both of which fell a sacrifice to this unwholesome climate before they had reached the object of their wishes.

You have to feel for these men; they had rounded Cape Horn against wind and tide; they had taken their ship across the Pacific to Tahiti to observe the transit of Venus, then turned south to face more violent storms in search of a suspected southern continent; they had circumnavigated both North Island and South Island of New Zealand again with heavy swells and storm force winds; they sailed the whole of the east coast of Australia, sounding with a lead most of the way; they survived the grounding of the ship on the Great Barrier Reef when only their efforts at pump and windlass saved them; they proved there was a passage between Australia and New Guinea; and with a ship that was battered and worm-eaten they had limped to Batavia.

These giants of adventure were laid low by the microscopic organisms of dysentery: viruses, bacteria, protozoans, and parasites of various types. Too little was known of the mechanisms of dysentery and the preventive measures against it and they paid the price. The illness had no respect for rank; Mr. Monkhouse, the ship’s surgeon, Charles Green, the astronomer from the Royal Society, and Sydney Parkinson, natural history painter in the retinue of Joseph Banks, all eventually succumbed to the ‘flux’; and the disease ran through all other ranks including: the boatswain, the carpenter, the sailmaker, and a whole swathe of marines and seamen.

Cook completed his description of Batavia with the following text:

Batavia is certainly a place that Europeans need not covet to go to; but if necessity obliges them, they will do well to make their stay as short as possible, otherwise they will soon feel the effects of the unwholesome air of Batavia, which I firmly believe is the Death of more Europeans than any other place upon the Globe of the same extent. Such, at least, is my opinion of it, which is founded on facts. We came in here with as healthy a Ship’s Company as need go to Sea, and after a stay of not quite 3 months left it in condition of a Hospital Ship, besides the loss of 7 men; and yet all the Dutch Captains I had an opportunity to converse with said that we had been very lucky, and wondered that we had not lost half our people in that time.

What happened next is portrayed in a Google Earth presentation which plots Endeavour’s track after leaving Batavia. She was bound for England by way of the Cape of Good Hope. Not long after passing through the Straits of Sunda and while heading out into the Indian Ocean towards the trade winds, the men began to die. In the next 34 days there were 23 deaths. How very disheartening that must have been for the man who had kept scurvy at bay for 3 years and more.

Clearly, a bracing sea cruise is not the cure for dysentery. Cook felt that matters improved once they reached the trade winds, but the two screenshots above show the trail of death right across the Indian Ocean until Endeavour was to the south of Madagascar. Cook recorded the last deaths as follows:

Wednesday, 27th (February, 1771). Ditto Gales and Cloudy. In the A.M. died of the Flux Henry Jeffs, Emanuel Parreyra, and Peter Morgan, Seamen, the last came sick on board at Batavia, of which he never recover’d, and the other 2 had long been past all hopes of recovery, so that the death of these 3 men in one day did not in the least alarm us. On the contrary, we are in hopes that they will be the last that will fall a sacrifice to this fatal disorder, for such as are now ill of it are in a fair way of recovering.

Captain Cook in Google Earth: migration to the web complete(ish)

leave a comment »

I have been working for a couple of weeks converting my Google Earth presentation of James Cook’s first voyage round the world so that it runs in a web browser using the Google Earth API.

All of the Google Earth ‘tours’ are now transferred to providing more than 15 hours of animation and audio. I hope that education and GIS professionals as well as those interested in adventure, exploration, and discovery, will find this presentation interesting and useful.

There are several advantages to the new site:

  1. The menu system makes it easy to find the part of the voyage that interests you.
  2. All of the legs of the voyage are accessible from the menu; previously you had to load each tour separately into the Google Earth application. The ‘ish’ in the title is there because I have not yet prepared the section of the voyage from Batavia to England and I have not included the passage from Cape Horn to Lagoon Island. For the sake of completeness I will add these sections at a later date.
  3. The tours in the presentation are each limited to about 10 minutes duration, and they now load much faster than they did in Google Earth.
  4. After completing a large part of this project I realised I needed some  automation tools. Consequently, I developed TourMaker which uses <ExtendedData> attached to <Placemark> elements to describe how the 3D model should be moved. This eliminates much of the manual effort required to create animations in Google Earth; this in turn made it easier to model Cook’s voyage in finer detail. I particularly like how Endeavour now rounds Cape Horn and later visits a string of South Seas islands both on the approach to Tahiti and on leaving that island after observing the transit of Venus.
  5. I have made fresh sound recordings of much of Cook’s journal; I bought a copy of WavePad to do this and, as in many other situations, I discovered the need to do the job twice: the first time to learn how to do it, and the second time to do it properly. The early recordings were rushed, the levels were inconsistent, and the sound effects were too prominent. I hope these issues are now resolved.

Captain Cook in Google Earth: North Island, New Zealand

I am busy chopping up and rearranging the Google Earth tours I prepared last year which present Captain Cook‘s first voyage round the world. Today, I added the circumnavigation of North Island, New Zealand to the new website which can be found at:

The screenshot above shows Mount Egmont in the south of  North Island.

Captain Cook in Google Earth: a new presentation

leave a comment »

I have felt for a while that my presentation in Google Earth of Captain Cook‘s first voyage round the world is a little unwieldy and slow to load. Therefore, I have created a version using the Google Earth API that allows the voyage to be viewed in a web browser.

By chopping up the voyage into sections of about ten minutes duration, the audio files load much faster; and those who are reluctant to install the full Google Earth application can still view the presentation.

Captain Cook in Google Earth: Cape York to the Indonesian seas

The channel next to the mainland was blocked by shoals and rocks (22Aug1770)

Even before reaching the western edge of Cape York it was clear that there was a passage to the south-west between the mainland and some islands. Cook instructed the smaller boats to sound the first channel between the mainland and the first island. They found this to be blocked by rocks and shoals, so Cook gave the signal for them to try the next channel. Here they found not less than 5 fathoms and they sailed through to anchor a few miles beyond the entrance to the channel.

Entrance to Endeavour Strait (22Aug1770)

Cook looked between the mainland to the south-west and Cape Cornwall on Prince of Wales Island:

Between these 2 points we could see  no land, so that we were in great hopes that we had at last found out a passage into the Indian seas; but in order to be better informed I landed with a party of men…upon the island which lies at the south-east point of the passage…after landing I went upon the highest hill which, however was of no great height, yet no less than twice or thrice the height of the ship’s mastheads; but I could see from it no land between south-west and west-south-west…

Possession Island

There is ambiguity on the internet concerning the island on which Cook landed. Look at this snapshot:

Will the real Possession Island please make itself known?

Will the real Possession Island please make itself known?

Wikipedia (places named by James Cook) goes for the island at the north-east end of the passage; surely that can’t be right. There are certainly some errors in Cook’s journal, but would he go to the island that was lower than the one next to it and further away from the direction he wanted to look?

The Google Earth Borders and Labels layer plumps for a patch of very low lying reef; certainly that is wrong.

I  chose for the tour the island that is actually at the south-east end of the entrance to Endeavour Strait and is actually high enough, at 70 metres, to be ‘no less than twice or thrice the height of the ship’s mastheads’.

There was no land to the south-west

There was no land to the south-west

Even from this vantage point Cook was still objective to the point of reticence:

Having satisfied myself of the great probability of a passage thro’ which I intended to go with the ship, and therefore may land no more upon this eastern coast of New Holland…I now once more hoisted English colours, and in the name of His Majesty King George The Third took possession of the whole eastern coast.

we fired 3 volleys of small arms which were answered by the like number from the ship

The following day, Endeavour sailed the length of Endeavour Strait and steered north-west for the small island which Cook named Booby Island (no prizes for guessing why). On entering Torres Strait, Cook noticed the swell from the south-west. This convinced him that there was no land in that direction for some distance and therefore:

…we had got to the westward extremity of Carpentaria, or the northern extremity of New Holland, and had now and open sea to the westward; which gave me no small satisfaction, not only because the danger and fatigues of the voyage was drawing near to an end, but by being able to prove that New Holland and New Guinea are two separate lands or islands, which until this day hath been a doubtful point among geographers.

Today, I added this leg of Cook’s exploration of the Australian coast to my Google Earth tour which presents his first voyage round the world. This leg completes my documentation of Cook’s exploration of Australia, from Point Hicks in the south to Cape York in the north.

Along the way Endeavour made an extended visit to Botany Bay, ran aground on a reef, was repaired in Endeavour river, passed outside the reef through Cook’s passage near Lizard Island, only to be nearly smashed to pieces on its outer edge a few days later. The ship was saved by being able to re-enter the reef system through Providential Channel.

Through perseverance and cautious navigation, Endeavour rounded Cape York less than a week later. Cook landed on Possession Island, from the summit of which he began to believe that he had found a passage between New Holland and New Guinea.
