1) According to my own reserch, about 17 remains referd to the subject are numberd, 15 of which I have examined. 2) Having studied their values aethetically, historically, & tecuically, I here propose a classifying table as follows :(snip) Of their very Japanese names & situations, I ask to my readers to refer to my own corresponding report in Japanese (at the top of the paragraph 2). 3) Much as I regret it, still no real history is testimonyed in relation to the traditional designer ("Sesshu") ; while the tradition itself could be gone back sometimes to more than 200 years ago or 300 perhaps. 4) With regard to their constructing materials, treatmen t s & other data, I would like to propose 2 great distinguishing types out of them. Type A. Built on some natural mountain-foot or hill-side ; front side being technically determined rather in one direction only ; artificial gardenpond or -lake ; rocking waterfall-way (water itself is scarcely going down now at least ; stone garden -bridges ; trees & bushes (such as azaleas, pines, cherrys, maples & other evergreen broad-leaves etc.) .. (Remains No. 4, 7, 11, 5, 6, 8 & 14 etc.). Type B. In t h e middle of some small artificial garden-pond or -lake, rock groups naturally (not even symbolically) representing a tortoise, upon which as well as their garden-lake side, some auspicious garden trees (based upon the Japanese old traditions,) such as pine. plume, bamboo & other are adorned, .... (Remains No. 10 & 13). 5) Type B shall be built not before than about 200 years ago perhaps.
