IMITATIONS AND DOCTORED
The beds where the culture of these artiĀ­ficial pearls is carried on, are situated in the Bay of Ago, a few miles south of the Temple of Ise, in central Japan on the Pacific side.

A little north of the centre of the bay is a small island called Tadoko where the necessary buildings and the men connected with the industry are.
