BOOK XI.

The fourth wall is one hundred and fifty-one feet long. The height of each ofthese walls, and likewise of the other two and of the transverse walls, ofwhich I will speak later on, is ten feet, and the thickness two feet and asmany palms. The second long wall only is built fifteen feet high, becauseof the furnaces which must be built against it. The first long wall is distantfifteen feet from the second, and the third is distant the same number of feetfrom 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 beginningof the first long wall to the beginning of the second long wall; and the secondtransverse wall from the beginning of the second long wall to the beginning ofthe fourth long wall, for the third long wall does not reach so far. Then fromthe beginning of the third long wall are built two walls—the one to thesixty-seventh foot of the second long wall, the other to the same point inthe fourth long wall. The fifth transverse wall is built at a distance of tenfeet from the fourth transverse wall toward the second transverse wall;

Nomenclature. —This process held a very prominent position in German metallurgyfor over four centuries, and came to have a well-defined nomenclature of its own, which hasnever found complete equivalents in English, our metallurgical writers to the presentday adopting more or less of the German terms. Agricola apparently found no little difficultyin adapting Latin words to his purpose, but stubbornly adhered to his practice of using noGerman at the expense of long explanatory clauses. The following table, prepared for con-venience in translation, is reproduced. The German terms are spelled after the mannerused in most English metallurgies, some of them appear in Agricola’s Glossary to De ReMetallica.
