This ground must, of course, be quitenear the culturist, and easily accessible. Figure 2, plate vni, shows oyster groundsat Kusatsu, and conveys a good idea of their extent. , about 2 miles east of Hiroshima, the nature of the oyster groundshas necessitated the development of a most elaborate system of oyster the main part of the grounds is in a sheltered inlet, or rather in an enlarged. itt ; - KunlMM i-nlltcinrs arranged after tin- fashion common in Kusatsu.

As 1 think, for this very reason the spat collecting is done just outside the inlet. Here, inApril, w-hen the breeding season begins, bamboo collectors, four or rive in a bundle,are planted in close clusters along the channel to receive the spat. Figure 1. plate ix,shows two of these clusters. At t he end of the breeding season — that is. in the latterpart of August—the collectors are uprooted and conveyed inside the inlet, carebeing taken not to injure the spat upon them. There they tire built into peculiarstructures called tbya, which tire round pyramidal in shape, and measure to 4 feet high and .> to 6 feet across at the bottom (sec tig. 2, pi. ix. left side).A toya is constru
