feet), and a shed on the south (30 by 96 feet) for storing the raw 
material. They are arranged in a north and south line, with a 
fifty-foot space between them, excepting that the coal shed ap- 
proaches more closely to the power house. See Plate X XIX for 
an illustration of this plant. 
Plate XXX shows these buildings in ground plan, Figures 4, 
5, and 6, and the calcining building and power house in ele- 
vation, drawn on a larger scale, Figures 1, 2, and 3. The cal- 
cining building is 30 by 34 feet, with a coal shed at the east 
end 12 by 48 feet. 
Figure 4 shows the location of the two kettles with the ma- 
sonry walls surrounding them and the hot-pits to the rear, into 
which the plaster runs directly from the kettles. It also shows 
the position of the main drive wheel for propelling the scrapers, 
and the tunnel for drawing the raw material from the shed to 
the base of the elevator which elevates it for filling the kettles. 
Figure 1 is a side elevation of the same building, 4nd Figure 2 
an end elevation, each drawn to double the scale of Figure 4. 
Figure 1 shows the details of the elevator for lifting the raw 
material, of the suction fan for carrying the calcined plaster 
from the hot-pits to the receivers at the top of the building, of 
the bolts near the top where the plaster is sifted to exclude all 
coarse material, and of the south end of the auger conveyor 
which carries the sifted material across to the warehouse. It 
also shows the arrangement of the drive wheels propelled by the 
rope belting from the power house, and how motion is conveyed 
to the various parts of the machinery from these two main drive 
wheels. 
Figure 2 shows in a different section the interior of the cal- 
cining building with the arrangement for propelling the scra- 
pers, and different wheels and pulleys used in giving motion to 
the hfting and sifting and conveying machinery. 
Figures 3 and 5 represent the power house, with the boiler, 
the heater, the water tank, the pumps, and the drive wheel in 
place. The machinery in the calcining building is propelled by 
a series of rope belting reaching from the power house.
