| Victoria’s 2002 Selwyn Night |
|
The Victorian Division’s annual highlight,
the Selwyn night, was held in the ICE Theatre in Museum Victoria on
9th May 2002. The venue was most appropriate as the occasion coincided
with the opening of the map exhibition ‘Beneath our Feet’,
commemorating 150 years since Selwyn arrived in Victoria. The large
attendance took advantage of the opportunity to examine the exhibition
after the lecture.

| The 2002 Selwyn Lecture |
The
2002 Selwyn Lecture was delivered by Thomas A. Darragh. Tom studied
geology at Melbourne University, gaining his PhD in 1982. After two
years working in the Geology Department of the university he joined
the National Museum of Victoria in 1965 as Curator of Fossils, and
became deputy director in 1973. When the National Museum amalgamated
with the Science Museum, he returned to research as Head of Geology
and became a Senior Curator in Palaeontology in 1996. As is so often
the case with senior staff, he retired following downsizing of the
geology staff in June 2000 after 38 years with the Museum. |
Tom’s
major research interests are surprisingly wide-ranging, from Tertiary
mollusca and biogeography to history, of Germans in Victoria, of geological
studies in Victoria, and of engraving and lithography in colonial
Victoria. He has written several books on these topics and continues
his reseach in these various fields. |
| 2002 SELWYN LECTURE: A series of beautiful maps…a credit to the Colony. |

When
Alfred Selwyn arrived in Melbourne in 1852, Victoria had a geologist
but as no one seemed to know what he should do—this was left
up to Selwyn himself. He decided his main task was to construct a
geological map of the Colony accompanied by cross sections and short
explanatory memoirs. |
His
first report, on the Mount Alexander goldfield, was ready in 1853
but, whilst printing it was easy, the map was a different matter.
Fortunately for him, the young and energetic Andrew Clarke had just
been appointed Surveyor General and established a lithographic branch
of the Lands Department to undertake the production of maps. Selwyn's
map was one of the first maps to be printed, with colours applied
by hand. The lithographic stones were of Solnhofen Limestone, from
the same quarry in which Archaeopteryx had been discovered. |
Without
Selwyn working on his own the work proceeded slowly, leading to agitation
from goldfields members of Parliament to funds being granted for proper
mineralogical and topographical surveys. Selwyn engaged a draftsman
and sufficient staff to mount four field parties under Norman Taylor,
Christopher Aplin, George Ulrich and Richard Daintree and decided
on a grid pattern at a scale of 2 inches to the mile. As the full
maps were very large they were published in four portions—the
famous ‘Quarter Sheet’ series. Maps were to be engraved
for publication. The engraved lines included the map border, cultural
features, cadastral boundaries, creeks, topographic lettering, and
geological boundaries, but no representation of relief. The legend
and scale were also engraved on some maps. |
After
engraving, Selwyn was faced with the problem of issuing coloured geological
maps. Printing large numbers directly from a copperplate was impractical
and hand colouring was prohibitively expensive. A faster, cheaper
option was colour printing by lithography. This process involved making
a print from a copperplate onto lithographic transfer paper and then
putting the transfer paper on a clean lithographic stone image-side
down, transferring the image to the stone which could then be used
to print the map. Each colour needed its own stone. The map would
be run through the press as many times as there were colours to apply
to it. Registration of the colours was the main problem, and was achieved
by having two marks on the stone (usually at line corners so as to
be unobtrusive) to which the paper was aligned by using a stick with
two pins that matched the marks. The pins were pushed through the
paper and aligned with the marks on the stone. |
Colour
printing of maps was still in its infancy in the 1850s. Attempts had
been made in France, Austria and Germany in the 1840s, with some success,
but only the Austrian and French geological surveys used it to any
extent. In Britain it was not applied to official geological maps
until 1896 and hand colouring of older maps continued until the 1920s.
There was therefore very little precedent to guide Selwyn or his staff. |
By
April 1858, Selwyn had eight quarter sheets ready for publication
and another 13 surveyed but not fully engraved. In the same year he
met Joseph Aresti who had colour printed John Mylne's Geological Map
of London in 1851, the first colour printed British geological map.
Aresti was given the task of printing two maps but these were not
up to the standard expected by Selwyn, although they have the distinction
of being the first colour printed geological maps in Australia, if
not the southern hemisphere. |
At
the same time, John Phillips, a Cornish mining engineer, had been
directed by the Surveyor General to map the Ballarat Goldfield geologically,
completely independently of Selwyn's Survey. Selwyn was landed with
the task of publishing the map. Printing went to the lowest tender,
by Fergusson & Mitchell, but the maps were poorly printed. Most
were rejected by Selwyn, who was making little progress in getting
his maps printed. To break the logjam, the Lithographic Printing Branch
was set up in 1858 with Thomas Ham in charge at £400 per year,
a hand lithographic press was purchased as well as lithographic stones
and inks, and work commenced on printing maps in colour. |
|
Although Ham’s first map was available mid-1859 it was never formally issued and the first maps actually issued for sale appeared in April 1860 and comprised the four sheets making up the map of the Melbourne area. One thousand copies of each were printed, which involved passing each sheet of paper through the hand press eight times. This sheet involved 12,000 handlings, and for the four sheets making up the Melbourne map, a total of 36,000 manipulations were required. Given the backlog even this method was not speedy enough and Ham suggested a further innovation, the application of steam power to drive the press, which would not only save much hard labour, but would also increase production 4 or 5 times. A power press was purchased from England and installed in the Government Printing Office and began work in November 1860. Selwyn now had two presses working: the newly imported power press as well as the first hand press, altered to work as a power press. By the end of December 1860, five maps were printed and issued to the public and six others were at various stages of production. In addition, several plates were printed for a work on the natural history of Victoria by Frederick McCoy, Director of the National Museum of Victoria. As an indication of the pride Ham and his superior felt about these innovations, the maps carried the imprint 'Lithographic Steam Printing Executed by the Geological Survey Department at the Govt. Printing Office, Melbourne.' |

However,
all achievements came to an unhappy end in 1860 when the Lithographic
Branch was suddenly abolished because of political changes. Ham's
reward for his hard work was dismissal. During the three months in
which he was retained, he managed to finish a few maps that were still
in progress. Later in the year, after another change of Government,
the Lithographic Branch was reconstituted with a much smaller staff.
When the Geological Survey was abolished in December 1868 it had issued
59 quarter sheet maps, with the remaining maps in progress (six remaining
quarter sheets, several goldfield maps, two geological maps of Victoria,
two of Australia as well as many mining plans and illustrations for
departmental publications) finished soon after. The Lithographic Branch
had produced some of the finest geological maps ever to be printed
in Australia.
