The caldron immediately above the
flames was of course boiling; and, on the
water being withdrawn for use, it was con-
trived that an equal portion should replace
it from the tepidarium, into which at the
same time the frigidarium was discharged.
It does not seem improbable, from the
appearance of the place, that there were
three columns of these caldrons at Pompeii
dependent on a single fire; and if so, the
upper caldron of the column nearest the
cistern, 10, contained water nearly cold, and
hence that was probably derived which rose
in the centre of the labrum, and must have
had a higher level.
From one of these, or the cisterns ad-
joining, the circular bath, or natatorium,
was also supplied, through tubes yet to be
traced in the wall.
We read of some of these vases, or cis-
terns, which were made of lead, and called
miliaria; but these were, of course, far from
the furnace, and were so named because of
