The aslii 1. ,pitD should benot less `than `eighteen inches wide at it knownthat I, THOMs A.` KIRK, ofl Kansas ,Q City, inthe county ofJa'ckson and ,State ofltlisshuri, have invented `a `new` and useful Improvement 'in My invention hasfr,` its object to' furnish1 an im advantages `are attained, as-` the top, thirteen inches wide at the bottom, and about -six feet long, and should -be builtV with thirteen-inch walls. f

In building -the walls of the furnace the bricks should be laid with their ends to the'fire, and from, two to four inches apart. `,VS/hen the walls have been carried up` two, three, or fouitxcoursesha stretcher sbouldbeV placed uponV the bricks', binding them together and forming the lire-holes. 4Another set ofv tire-holes is then formed above the'stretchers, and so on for about two-feet in height.'

I The walls of the furnace are then finished without `fire-'hole's, to form a space in the upper part of the furnace foriburning the smoke, thus increasing the heat, economizing'fuel, and preventing the lime from heilig discoloredby thessmoke.

The furnace should be about six feet long, two feet wide, and fonigfeethigh, and should be arched from front to rear., y Y

Thebottom' of the furnace may be formed of grates, or, if desired, the top of the ash-pit may be arched over, and the bottom of the furnace made inclined, with openings at .the sides about six inches in width, o allow' thecoalsand aslresl'to'tll against the liningl of the cupolas. "The port-holes may all be in front,'ii` desired. i Y When' only bneside or part of the kiln is -to be used,- the port-holes upon thejother side may all be closed 4 l The lining of the kiln should be of lire-brick laid in remortar, or of other fire-proof substance. The outer walls may be of stone or commony brick laid in brick-clay mortar, except the parts exposedto the weather, which should be laid with lime-and-sand mortar. f

The sidesV of theV draws B next tothe furnace should be straightpor inclined somewhat inward, 'so that the lower partsv of the 'said draws willl be pantially beneath the furnace. This arrangement of the draws B B enables them to be discharged of .their contents at nearlythc same point, and vinto the same receptacle, when desired;

'site side, besides allowing the flame to come inv actual C contactv with the rock; thus no unburnt rockwill escape. n e

The furnace should` be provided with draugheholes F, inthe ordinary` manner. I u
