「近代の文化遺産の保存理念と修復理念」英語版

63　Although from the point of view ofarchitecture, some traces may be taken asmarks of damage, they may be important whenviewed as traces of history of industrial heritageproperties. Of the many sites I have experienced,the most exemplary is the case of the crushingplant at Sado Mine. At the crushing plant,large stones are split, rolled down the line, andfiltered; those that came through the filterwere crushed by machine. These rolling stonesnaturally made marks on the inside of concretewalls as can be seen in Photo 6. Damage onthe exterior due to weathering needs to berepaired, but however appropriate it may befor preservation of cultural properties from thepoint of view of architectural history, to restorethe interior back to the state of completionwould result in not only the loss of what tookplace here, but also in greatly diminishing itssignificance as an industrial heritage property.　Also, at this crushing plant were left largetatami mats lined with steel plates (Photo 7).These mats were used in the process of crushingstones that were too large and left unfiltered.Dynamite was cut up into small pieces to beapplied onto these stones and then blasted;these mats were used to cover the explosion, sothat surrounding areas would not be affected.Photo 8　 Walls above windows coverd with paper to preventdraft / Tomioka Silk Mill Cocoon House, second floorPhoto 6　 Walls of Sado Mine crushing plantPhoto 7　 Tatami mats used as shields at Sado Mine crushingplantAfter having been explained this procedure, Ilooked around the room and noticed numerousholes in the walls and ceilings. At first, Ithought they were signs of aging, but manywere made by the blasted stone pieces. Theseare clear traces of the industry in operationand need to be carefully preserved duringrestoration. The tatami mats, although the rushmaterial is starting to rot, are important as well.Clearing the buildings of their contents needsto be carefully executed after learning how theplace and equipment were used. If not, valuabletraces of heritage would be lost.　Going back to Tomioka Silk Mill, becausean area on the first floor of the West CocoonHouse was originally used for coal storage, therewere no walls on the side facing the inner yard.
