    Rogers Impts. in the Preparation and Manufacture of Peat into Fuel, dfc. produced, and the nature of the “ mould mull or upper surface,’5 to be acted upon. In the Specification of my Patent, before-mentioned, I have described a mode of charring peat by piling it up in pyramidal furnaces from which the air is to be excluded at a certain period of the process, but as a more perfect 5 exclusion of atmospheric air than has yet been attained*ds essential to the economical and abundant production of charcoal from peat, I have invented the following means for effecting this object. It will be seen by the Drawings that the pyramidal furnaces are placed under an air chamber, according to my Patent of One thousand eight hundred 10 and forty-eight, but instead of an ash-pit being made from end to end of the shed, with doors to close and exclude the air from the burning mass of peat in the furnaces, (which plan in practice I have found required greater nicety of workmanship than was desirable,) I form a shallow tank which extends from end to end of the shed to receive the pyramidal furnaces containing the peat 15 to be operated upon, and I run these furnaces, which are mounted on wheels, into and out of the tank over inclined planes at either end thereof, as shewn in the sectional elevation, Fig. 1. The furnaces being placed in this tank the process of burning takes place, and as soon as the masses of peat within the furnaces are brought to a red heat throughout, water is admitted by a pipe 20 prepared for the purpose into the tank, and rising to the height shewn by the red line, or about an inch or two above the bottom edge of the furnace sides, the passage of the air between the fire bars will be immediately cut off, the furnaces are then closed at top, according to the mode stated in my Patent of One thousand eight hundred and forty-eight, and the charring operation is 25 completed in the space of four, five, or six hours. Having now described my Invention, and the manner of carrying the same into effect, I wish it to be understood, that under the above in part recited Letters Patent, I claim as my Invention of improvements in the preparation of peat, and in the manufacture of the same into fuel and charcoal, first, the 30 means herein-before described for treating the general refuse of bogs, and the 44 dust and mould,” or 44 mull55 of peat, so as to convert it into fuel or char¬ coal ; and, secondly, I claim the mode of excluding the atmospheric air from the charring or carbonizing furnaces, as above described. In witness whereof, I, the said Jasper Wheeler Rogers, have hereunto set 35 my hand and seal, this Seventeenth day of March, in the year of our Lord One thousand eight hundred and fifty-one.
