The fourth wall is one hundred and fifty-one feet long. The height of each of
these walls, and likewise of the other two and of the transverse walls, of
which I will speak later on, is ten feet, and the thickness two feet and as
many palms. The second long wall only is built fifteen feet high, because
of the furnaces which must be built against it. The first long wall is distant
fifteen feet from the second, and the third is distant the same number of feet
from the fourth, but the second is distant thirty-nine feet from the third.
Then transverse walls are built, the first of which leads from the beginning
of the first long wall to the beginning of the second long wall; and the second
transverse wall from the beginning of the second long wall to the beginning of
the fourth long wall, for the third long wall does not reach so far. Then from
the beginning of the third long wall are built two walls—the one to the
sixty-seventh foot of the second long wall, the other to the same point in
the fourth long wall. The fifth transverse wall is built at a distance of ten
feet from the fourth transverse wall toward the second transverse wall;

Nomenclature.—This process held a very prominent position in German metallurgy
for over four centuries, and came to have a well-defined nomenclature of its own, which has
never found complete equivalents in English, our metallurgical writers to the present
day adopting more or less of the German terms. Agricola apparently found no little difficulty
in adapting Latin words to his purpose, but stubbornly adhered to his practice of using no
German at the expense of long explanatory clauses. The following table, prepared for convenience in translation, is reproduced. The German terms are spelled after the manner
used in most English metallurgies, some of them appear in Agricola's Glossary to De Re
Metallica.
