This photograph shows a stack of apricot trays on a push car. Each tray on the push car was lined with pitted apricots halves. The stacked apricot trays would then be pushed inside a sulphur house and the sulphur would be lit, creating sulphur dioxide, which turns the apricots a bright orange. The apricots would remain inside the sulphur house for one day.
The trays of apricots would then be unstacked and placed in the sun for five to seven days to dry.
The photograph was taken around 1910, on the north side of Church Street, in Piru, CA
