Book excerpt: Excerpt from The Discovery and Geognosy of Gold Deposits in Australia: With Comparisons and Accounts The first discovery of gold in placer deposits in the Australian colonies is an event so intimately interwoven with the associations and adventures of my own experience, that, reluctant as I might feel under ordinary circumstances to intrude private history upon ublic notice, I should in this instance fall short in my endeavour to do impartial justice to the subject were I, in mistaken modesty, entirely to omit an autobiographical introduction. But first let me ex lain what is meant by the term lacer deposits. The raw go (1 of commerce exists in nature c 'efly under two conditions. In the one it exists in a visible and metallic state, disseminated through, and encased within, stony matrices, mostly of quartz, which in veins or dykes, or (to use a technical expression more recently adopted) reefs, usually traverse massive rocks of crystalline or slaty character in a direction nearly vertical. In the other condition, from which it is in practice by far the more abundantly obtained, the metal in free grains exists in deposits Spreads horizontally beneath pebbles, clays, and drift, which also rest directly upon the said massive roc s of crystalline and slaty structure.
