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 Greatest Explorer, Ebury Press, 2002

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

John his elder brother having taken Holy Orders established a school in Soho, London. Charles found his ‘heavenly passion’ astronomy. After he graduated Charles staying on for a time to assist John with the teaching of mathematics.

In 1760 Charles applied successfully for the position of Assistant Astronomer at Greenwich Observatory. He served three (3) Astronomer Royals in that capacity.

James Bradley first of these men had, in 1742, succeeded Edmond Halley of comet fame who held the post of Astronomer Royal for twenty-two (22) years from 1720-1742.

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 – 2017 – Bradley’s calculations were amended to 299,790 km (186,290 miles) per second.

If only Bradley had stuck to light and left time and longitude to Mr. John Harrison inventor of the sea-going ‘pocket-watch’ – an accurate marine chronometer – many a sea-farer would not have met a watery end. Bradley’s tenure lasted twenty (20) years he died in 1762.

MOON VERSUS MACHINE

Compared with that of Banks, Mr. Green’s equipment was comparatively modest. On May 5th, 1768, at a meeting of Council of the Royal Society it was resolved that the instruments for the use of the Observers of the South Latitudes be the following:

¬†Two [2] reflecting telescopes of two [2] foot focus…[1] brass Hadley’s sextant, [1] barometer bespoke of Mr Ramsden, [1] Journeyman’s Clock bespoke by Mr Skelton, two [2] Thermometers of Mr Bird, [1] Stand for Bird’s Quadrant, [1] dipping needle bespoke by Mr Ramsden’. H.C. Cameron, Sir Joseph Banks, Angus and Robertson, Sydney, 1966

Here two (2) of a plethora of questions must be asked. Who was Mr. Green and why did HMS Endeavour sail on such an important voyage without Mr. John Harrison’s H-4 chronometer?

‘From the coast of China it [New Holland] lies not more than about a thousand leagues and nearly the same distance from the East Indies, from the Spice Islands about seven hundred leagues, and near a month’s run from the Cape of Good Hope…or suppose we were again involved¬† in a war with Spain, here are ports of shelter and refreshment for our ships, should it be necessary to sent any into the South Sea’.
