A new plant, modelled like the Caladiums, the Alocasia Metallica, excited him even more. It was coated with a layer of bronze green on which glanced silver reflections. It was the masterpiece of artificiality. It could be called a piece of stove pipe, cut by a chimney-maker into the form of a pike head. The men next brought clusters of leaves, lozenge-like in shape and bottle-green in color.
Centuries of hard scouring have obliterated this; but the upper and lower ends of most of the letters can just be traced. An expert can satisfy himself that the inscription as preserved by Gunton is practically correct. It seems to have been this, though it is not possible to vouch for every letter.

"Georgius Agricula also was of opinion that it was a mere delusion of the devil to inveigle the avaricious and unwary into his clutches, and in his treatise 'de re Metallica, lays particular stress on the mysterious words pronounced by those persons who employed the divining rod during his time.
The quantity of bars that fills the yards and warehouses of this quarter strikes with astonishment the most indifferent beholder." PENNANT, Account of London, 309.

Reprinted and published at the Great Seal Patent Office, 1858.
Thus, immediately on Sturtevant's failure becoming known, one John Rovenzon, who had been mixed up with the other's adventure, applied for a patent for making iron by the same process, which was granted him in 1613. His 'Treatise of Metallica' shows that Rovenzon had a true conception of the method of manufacture.
Simon Sturtevant, in his 'Treatise of Metallica, published in 1612, estimates the whole number of iron-mills in England and Wales at 800, of which, he says, "there are foure hundred milnes in Surry, Kent, and Sussex, as the townsmen of Haslemere have testified and numbered unto me."
And three years later, that is in 1912, he privately published, in sumptuous form, with scrupulously exact reproduction of all of its many curious old woodcuts, an English translation of Agricola's "De Re Metallica," the first great treatise on mining and metallurgy, originally published in Latin in 1556, only one hundred years after Gutenberg had printed his first book.
"De Re Metallica" was the standard manual of mining and metallurgy for 180 years. Georgius Agricola, the author, was really one Georg Bauer, a German of Saxony, who, following the custom of his time used for pen-name the literal Latin equivalents of the words of his German name.
It is curious that Rovenson, in his Treatise of Metallica of 1613, describes a reverberatory furnace in which iron was to be smelted by pit-coal, though it does not appear that he succeeded in perfecting his invention. Dr.
According to Basil Valentin, the twig was regarded with awe by ignorant labouring men, which is still true. Paracelsus, though he has a reputation for magical daring, thought the use of the twig 'uncertain and unlawful'; and Agricola, in his 'De Re Metallica' expresses a good deal of scepticism about the use of the rod in mining.
