There was the trace of the pillar in the red brick warehouse of Kikugawa-shi. It is the device which is necessary for a blend of the tea. I install a pillar and a wall temporarily. I mix it with plural tea at the place. The details of the device are not known till now. I elucidated it from the trace of the building and an old photograph and the story of the old man. I record it by this report now because it is the method that has died out.
