It is obvious that` the ilues C ,and D need not be of exactly the same height and that 'the products ofcombustion can be disposed of otherwise than by a stack F.

' That I claim, and desire to secure by Let- -ters Patent herein, is!- 1. In akiln, a chimney having separate and distinct compartments, to wit: a compartment leading from thefurnace to the interior of the kiln, vand a compartment communicating with the interior of the kiln near Vthe. bottom thereof and discharging back into main flue the alr therein being heated by the y the interior the kiln. v f

2. In a kiln7 a chimney having a main or fire flue that takes air from the exterior of the I Y kiln, and a supplemental flue adjacent to the er and lower ends with the interior of tie I iln.

In testimony whereof I` aflix Amy signature in presence of two witnesses.
