1fourth long wall, is
placed a tie-beam which reaches from the first set of
middle rafters to the second set of middle rafters; upon the tie-beams is
placed a gutter hollowed out from a tree. Then from the back of each of
the first set of middle rafters a beam six feet long reaches almost to the gutter;
to the lower end of this beam is attached a piece of wood two feet long;
this is repeated with each rafter of the first set of middle rafters. Similarly
from the back of each rafter of the second set of middle rafters a little beam,
seven feet long, reaches almost to the gutter; to the lower end of it
is likewise attached a short piece of wood; this is repeated on each rafter
of the second set of middle rafters. Then in the upper part, to the first and
second sets of principal rafters are fastened long boards, upon which are
fixed the burnt tiles; and in the same manner, in the middle part, they are
fastened to the first and second sets of middle rafters, and at the lower part to
the little beams which reach from each rafter of the first and second set of
middle rafters almost to the gutter; and, finally, to the little boards fastened
to the short pieces of wood are fixed shingles of pinewood extending into the
gutter, so that the violent rain or melted snow may not penetrate into the
building. The substructures in the interior which support the second set of
rafters, and those on the opposite side which support the third, being not
unusual, I need not explain.

In that part of the building against the second long wall are the
furnaces, in which exhausted liquation cakes which have already been
“dried” are smelted, that they may recover once again the appearance
and colour of copper, inasmuch as they really are copper. The remainder
of the room is occupied by the passage which leads from the door to the
furnaces, together with two other furnaces, in one of which the whole cakes
of copper are heated, and in the other the exhausted liquation cakes are
“dried” by the heat of the fire.

Likewise, in the room between the third and seventh5 transverse walls,
two posts are erected on rock foundation; both of them are eight feet high
and two feet wide and thick. The one is at a distance of thirteen feet from
the second long wall; the other at the same distance from the third long wall;
there is a distance of thirteen feet between them. Upon these two posts and
upon the third transverse wall are laid two longitudinal beams, forty-one feet
and one palm long, and two feet wide and thick. Two other beams of the
same length, width, and thickness are laid upon the upright posts and upon
the seventh transverse wall, and the heads of the two long beams, where they
meet, are joined with iron staples. On these longitudinal beams are again
placed twenty-one transverse beams, thirteen feet long, a foot wide, and three
palms thick, of which the first is set on the third transverse wall, and the last
on the seventh transverse wall; the rest are laid in the space between these
two, and they are distant from one another three feet. Into the ends of
the transverse beams which face the second long wall, are mortised the
ends of the same number of rafters erected toward the upright posts
which are placed upon the second long wall, and in this manner is made
