It requires about a peck of coal a days with a small pro- 
portion of charcoal, for one fire; with this I manufacture 
eight gun barrels or twenty pistol barrels, or one quart 0 
this coal to a musket barrel.

I have used this kind of coal for the last two years, both 
for the malt-kiln as well as under the brewing copper, and 
also for distilling, for which purpose I find it to be superior 
to wood, cheaper, safer, and attended with much less labor. 
{In distilling, with thirty bushels of this coal and half a 
cord of wood (io raise occasionally the heat,) I disti! one 
one hundred bushels of grain in a still containing one hun- 
dred and twenty-five gallons, upon the common old con- 
enim in ten days, when I formerly used five cords of 
wood for the same quantity, talking depger sigs e and requir-

or drawing off the still, I have only to throw on some of the 
finest of the coal, and when again I want to raise the heat, 1 
put on a stick or two of wood. The length of the bars of my 
grate is twenty-two inches, of inch square iron ; they are set 
in loose, the ends widened, so that the bars may be about 7-8 
of an inch apart, and placed thus side by side, they make 
a grate of fifteen inches wide—the stills are set bare to the 
fire, about sixteen inches above the grate, with single flues 
passing round each still, with doors to the furnace.

and containing no sulphur, there is no danger of their smok-
