Lime-Sulphur Concentrate. 13 
The portable strainer box resting upon the end of the trough is held 
directly under the low end during filling and thus catches and re- 
moves the coarser sediment. The undesirable features of such plants 
are the necessity for dipping out the finished product and their more 
or less limited capacity. 
FURNACE-COOKING PLANTS 
Figure 5 shows a simple orchard plant built in a hillside and 
arranged so that the finished product may be drained by gravity, 
stored near by, and later run into the spray tank or containers, which 
may be filled by gravity directly from the storage barrels. The ele- 
Fic. 4.—A simple form of lime-sulphur cooking plant similar to those shown in [Figure 
3 but with practically triple the capacity. Three kettles afford means for continuous 
operation, one being used for heating water and the others for cooking the concentrate. 
An undesirable feature is that the finished product must be dipped out. 
vation of the storage barrels shown in Figure 5 necessitates the use 
of a hand pump. This might be eliminated if the topography per- 
mitted drawing and straining directly into the barrels. One hundred 
and fifty gallons at a cooking can be handled conveniently with a plant 
of this type. If the upper tank for heating water for a subsequent 
batch is provided, the time interval between cooking is materially 
reduced. 
Figure 6 shows a popular type of farm plant in which wood is used 
as fuel. Figures 7, 8, and 9 show, in plan and elevation, the details 
of the plant and Figures 10 and 11 show two arrangements of all 
equipment and indicate the sequence of operations in connection with 
this single-cooker furnace-type plant. In Figure 10 a level location 
is assumed with driveways leading to door openings A, 4, and ©, 
Figure 11 shows the same plant arranged for either hillside or level 
ground location. In this plant there are two tanks, one for heating
