LIEUTENANT WILLIAM DAWES – ‘THE ETERNAL FLAME’ & ‘UNIVERSAL TERROR’

Wednesday, September 6th, 2017

‘He [Dawes] was the scholar of the expedition, man of letters and man of science, explorer, mapmaker, student of language of anthropology, teacher and philanthropist. Professor G. Arnold Wood, Journal of the Royal Australian Historical Society Vol. X, 1924, Part 1

Aside from Kate Grenville’s 2008 fictional cardboard cut-out, star-struck Daniel Rooke of The Lieutenant, Australia knows very  little of Marine Lieutenant William Dawes and almost nothing of his pivotal role in revealing the why and wherefore of Britain’s military campaign against Australia’s First Nations –  a ‘war nasty and decidedly lacking in glory’. See: The Big Switch

‘English clockmaker John Harrison, a mechanical genius who pioneered the science of portable precision timekeeping…invented a clock that would carry the true time from the home port, like an eternal flame, to any remote corner of the world’. Dava Sobel, Longitude, Fourth Estate, 1998

1788 – 26 January, Warranne:  In Lieutenant Dawe’s care ‘an eternal flame’  K I – a faithful replica of John Harrison’s H – 4 ‘sea-going pocket watch’ fetched up at one particular ‘remote corner of the world’  – Sydney Cove – on 26 January 1788 aboard HMS Supply one (1) of eleven (11) ships of the ‘First Fleet’.

COOK – HARRISON – GREEN: THREE YORKSHIRE MEN WALKED INTO A BAR

Wednesday, August 23rd, 2017

 

 

‘He [John Harrison] wrested the world’s whereabouts from the stars, and locked the secret in a pocket watch’. Dava Sobel, Longitude, Fourth Estate, London, 1998

Harrison H-4 Chronometer

Since earliest times sea-faring nations England, Portugal, France, Spain the Netherlands vied with each other to solve – the Holy Grail of Navigation – longitude – calculating with precision a ship’s position at sea while beyond sight of land.

1714  – Westminster: Legislation, The Act of Longitude 1714, followed an enquiry into England’s first recorded 18th century maritime disaster.

In 1707 off the Cornish coast in heavy weather six (6) of Admiral Clowdisley Shovell’s ships having lost their bearings dashed to pieces against the Scilly Isles with the loss of 1500 lives.

As a consequence in 1714 The Board of Longitude was established to invite and evaluate submissions and award a prize of £20,000 to whom-so-ever solved the problem of determining longitude at sea.

To the detriment of the world’s seafarers the contest developed into a naked grab for cash. The king’s ransom, reckoned now more than £400,000,000 did much to delay recognition of the solution; ‘the perfect time-keeper…a pocket- watch’. .

There were only two (2) viable contenders for the Longitude Prize. Astronomer Royal Rev. Nevil Maskelyne’s Nautical Almanac – Luna Tables  and Star Cataglog –  a system favoured by a succession of Astronomer Royals – and John Harrison a Yorkshire carpenter with his invention a sea-going  pocket-watch’. See: Lotto and Longitude

‘The Board of Longitude was top-heavy with astronomers, mathematicians and navigators…[Harrison] made a special enemy of the Reverend Nevil Maskelyne the fifth astronomer royal, who contested his claim to the [Longitude] prize money and whose tactics at certain junctions can only be described as foul-play’. Dava Sobel. ibid.

The contest cost countless lives.

CAPTAIN COOK CAUGHT SHORT 

Tuesday, August 15th, 2017

The Royal Society had accepted the recommendation of the Astronomer [Royal ] that [Dalrymple] the well-known hydrographer of the Pacific should be chosen as ‘a proper Person to be sent to the South Seas’. H.C. Cameron, Sir Joseph Banks, Angus and Robertson, Sydney, 1968

 Rev. Nevil Maskelyne, Britain’s Astronomer Royal adjudged the hydrographer, a Fellow of the Royal Society; ‘a proper Person to be sent to the South Seas’. The Admiralty however would have none of Alexander Dalrymple. See: Malicious Maskelyne 

Instead Admiralty chose James Cook a lowly Warrant Officer of the Royal Navy to replace Dalrymple as Chief Observer of the Transit of Venus at Tahiti an event predicted to occur in early June 1769.

‘[Cook] Whose remarkable qualities as a seaman and as a navigator and cartographer the Admiralty had learned to value because of his outstanding service in the operation under [General] Wolfe in Canada [Seven Years War 1756-1763]. Cameron. ibid.

THE THIRD MAN – CHARLES GREEN

Tuesday, August 15th, 2017

‘The grim roll-call broke his [Cook’s) heart…the death of the astronomer Charles Green marked a wave of those who ‘departed this life’….By the end of January [1771] they had barely enough men to man the ship [HMS Endeavour]’. Vanesssa Collingridge, Captain Cook, The Life, Death and Legacy of History’s Greatest Explorer, Ebury Press, 2002

Charles Green son of ‘a prosperous’ free-hold Yorkshire farmer, born in Swinton towards the end of 1734, received a broad education with a strong emphasis on science.

John his elder brother took Holy Orders and established a school in Soho, London where Charles found his ‘heavenly passion’ astronomy. He stayed and taught mathematics after graduating.

In 1760 Charles Green applied successfully for the position of Assistant Astronomer at Greenwich Observatory. He went on to serve as Chief Assistant to three (3) Astronomer Royals, James Bradley, Nathenial Bliss and briefly Reverend Nevil Maskelyne.

In 1675 King Charles II engaged Sir Christopher Wren to design a National Observatory. Wren considered the ruins of Greenwich Castle a perfect site. For although Oliver Cromwell’s Roundhead Model Army had destroyed its buildings during The Protectorate Interregnum (1653-59) its foundations were intact.

In 1676, Rev. John Flamsteed, England’s inaugural Astronomer Royal, took up residence in the newly minted Greenwich Observatory. He remained in the role until his death in 1720.

Edmond Halley of comet fame succeeded Flamsteed holding  the post for twenty-two (22) years until his death in 1742.

Rev. James Bradley followed Halley. His tenure too was lengthy 1742-1762. Bradley is celebrated principally for his work on the speed of light. In 1728 he estimated light moved at the speed of 295,000 km (183,000 miles) per second. Three (3) centuries later Bradley’s calculations were amended slightly to 299,790 km (186,290 miles) per second

Had Bradley stuck to light and left longitude to Mr. John Harrison inventor of an accurate marine chronometer – a sea-going ‘pocket-watch’ – many a sea-farer would not have met a watery end.

MALICIOUS MASKELYNE

Monday, August 14th, 2017

‘The Transit [of Venus] was more than just an astronomical curio, it was the key to a wealth of information about the universe, information that would be seized upon by the intensely curious men of science who characterised the age’. Vanessa Collingridge, Captain Cook, The Life, Death and Legacy of History’s Greatest Explorer, Random House, 2003

1663 – England: In 1663 during the reign of King Charles II (1660-1685) a collection of ‘intensely curious men of science’ – the ‘Invisible College’ – morphed into the Royal Society.

A century later, the Society flowered under the patronage of King George III (1720-1820), to become one of the world’s most celebrated scientific institutions.

In 1767 with the Transit of Venus in the offing – 3 June 1769 – its second appearance that decade – the Society petitioned King George III for financial support to send observers to report on the phenomenon.

‘That the passage of the Planet Venus over the Disc of the Sun, which will happen on the 3rd of June in the year 1769, is a Phaenomenon (sic) that must, if the same be accurately observed in proper places, contribute greatly to the improvement of Astronomy on which Navigation so much depends.

 As the [Fellows] are in no condition to defray this Expense about £4,000 pounds, exclusive of the Expense of the Ships…with all humility and submit the same to your Majesty’s Royal consideration’. Cited, H.C. Cameron, Sir Joseph Banks, Angus and Robertson, Sydney, 1968

1768 – February: To that end James Douglas 14th Earl of Morton, then President of the Royal Society, on 15 February 1768 penned a Memorial requesting the Monarch’s financial support.

Royal money was forthcoming for it was clear accurate and reliable ‘Navigation on which so much depends’ equated with domination over the world’s oceans. Domination would expedite expansion of territory and trade and with strategically placed ‘bases’ more likely assure victory in time of conflict.

‘And the sum of £4,000 pounds clear of fees, [was] to be placed at the disposal of the Society…On March 5th of the next year, 1768, the Navy Board was instructed by the Admiralty to purchase a suitable vessel for the great voyage to the South Seas’. Cameron, Sir Joseph Banks, Angus and Robertson, 1968

1768 – 5 March: Admiralty settled on the Earl of Pembroke. Renamed Endeavour she was a typical coal carriercat-built bark’ of 368 tons ‘stoutly built, flatly bottomed of shallow draught’.
