Knocks the seed off and collects it in receptacle in the rear by vacuum. 23 Another seed collecting device that was first developed collected the seed from one row. Apparently these machines are rather inefficient as they have only been able to collect ten seeds per plant, while it is estimated each plant can produce from two to five thousand seeds per year. After the seed is dried, it is placed in air tight drums where it keeps almost indefinitely. 26 Chopped shrub at the bin where it has been dumped from the wagons from the fields.
Shrubs go through three sets of rollers before going into the mill proper.
The first settling tank. The wood silt becomes water logged and goes to the bottom. The rubber floats, together with some cork, the latter being removed by forcing water into the air cells of the cork under 350 pounds pressure, which sinks in the settling tank. This picture is out of order, and should be in following the next two. These giant crushers are filled with rocks.
