hat it does not often ap-pear in the market. Its habit of life in deep water per-haps has made its culture impossible. Because the habits of all oysters are very similar, themethods employed in rearing the Japanese oyster, thoughentirely independent in origin, are essentially like thoseof Europe and America. In the Inland Sea, as else-where, oysters require for the process of reproduc-tion the comparatively fresh waters of bays receivingstreams from the land. On the Japanese coast, as inEurope, localities having waters of the optimum densityare limited in area and more or less narrowly defined.At certain points, however, it is possible for the culturistto obtain his own set of young, and rear them for mar-ket on a single small plot of bottom which he hasrented. In Europe it is almost everywhere necessaryfor him to purchase his young oysters from anotherwho possesses ground on the very few bottoms favorablefor oyster reproduction. Japanese culturists have not adopted the tile collector

Oyster Culture in Europe and Japan 89 of the European industry, but retain the ancient and ef-fective brush collector. For this, the light, strong bam-boo is employed. It serves its purpose admirably, andis easily obtained. Short pieces, usually bearing theirbranches, are thrust into the bottom between tide lines.In this position they are easily examined and kept inorder. There is little trouble from mud, or the forma-tion of slime. The collectors, arranged in lines or clus-ters so as best to be exposed to the currents, are set outin the early spring, and young oysters begin to appearnear the middle of April and continue to attach for someweeks. The character of such a collecting ground iswell shown in Figures 22 and 23. Here the bamboorods are arranged in long rows, three or four feet inheight. If left to themselves, young oysters, greatly crowdedon the stakes, would not be able to attain a roundedform, and very many would perish. So those oystersthat have attained a certain size are
