The layout of a somewhat more elaborate home-built steam-cook- 
ing plant is shown in Figure 20. This might properly be called 
a concrete lime-sulphur plant, although parts of it could as well have 
been built of wood or metal and, like the one just described, requires 
a hillside location. Its arrangement, however, includes a storage 
tank beneath the working floor. It is thus possible to prepare con- 
centrate during spare time. The driveway directly in front of the 
lower side of the house permits filling the spray tank directly from 
the outlet pipe. Rain water from the roof of a near-by barn is stored 
in a tank located at an elevation higher than the cooking tank and is

the source of the water supply. Steam fer cooking is supplied by a 
boiler permanently placed in the cooking house and is introduced 
into a mixture through steam jets. When cooking is completed the 
solution is drawn off from the bottom of the cooking tank into the 
bottom of a filter tank adjoining it and is strained upwards through 
removable screens that rest upon a ledge just below the bottom of 
the outlet pipe that conveys the filtered solution into the storage 
tank. A hose connection is provided so that the lime may be slaked 
in a portable slaking box before it is introduced into the cooking 
tank. Sludge is removed through a pipe in the bottom of the filter 
tank, which extends through the side of the building. The concen- 
trate is diluted in the spray tank and if water supply stations are pro- 
vided at several points in the orchard, the weight that must be hauled 
from the plant is materially reduced.
