Description

Bradley recorded that ‘Cap Hunter went to Botany Bay in the Longboat
to visit the French Officers’ (Bradley 1969, 86, or SETIS, 26 February 1788).
Hunter stated in his journal:
as the two French ships already spoken of were preparing to leave
this coast, I determined to visit Monsieur de la Perouse before
he should depart; I accordingly, with a few other officers, sailed
round to Botany Bay, in the Sirius’s long-boat.
(Hunter 1968, 76, or SETIS, Chapter III)
Hunter’s account of his stay on board the Boussole gives us a glimpse
of the friendly, casual interaction between the officers of the First Fleet and
those of the Lapérouse expedition.
Whilst walking on shore with officers of the French ships at
Botany-Bay, I was shewn by them a little mount upon the north
shore, which they had discovered, and thought a curiosity; it was
quite rocky on the top, the stones were all standing perpendicularly
on their ends, and were in long, but narrow pieces; some of three,
four or five sides, exactly (in miniature) resembling the Giants
Causeway in the north of Ireland.
(Hunter 1968, 76, or SETIS, Chapter III)
That is a classic description of columnar or prismatic sandstone that is caused
by conducted heat and superheated steam when a volcanic intrusion occurs.
No date was given for Hunter’s walk with the French officers but
it was probably on Wednesday 27 February 1788. It is believed that by 10
March, the date of the departure of the expedition, some of these blocks of
columnar sandstone had been loaded onto the Boussole.
