Agricola, Herbert Hoover, and the "Pyramid Iron"

As mentioned in the backbone, Herbert Hoover, the 31st President of the United States from 1929 to 1933, was also a scientist and translated Agricola's "De Re Metallica" from Latin to English in 1912. He did that together with his wife, Lou Henry Hoover.
Agricola began his seminal book around 1533; it was published 1555 - after his death.
The comment about the history of iron technology can be found on p. 420 and 421 in my copy. Here it is:
