58of cutting down on materials and labor. Inmany cases, insufficient pouring of concreteor inaccurate placement of reinforcementresulting in thin concrete coverage can befound. At times, these imperfect conditionsof construction represent the industrialtechnology of the period. However, shouldsuch conditions be reproduced? Consideringsafety and durability, it would generally not beacceptable.　Secondly, there are many things that cannotbe fully understood until partial dismantlementfor restoration takes place, such as roofingmethods. Through dismantlement, the originalconstruction method could be clarified, but thestructure itself is lost. Even if restored to a statesimilar to the original composition using theoriginal materials, the possibility of being ableto reproduce all information provided by theartifact would be low.　If areas hidden from the outside can beconsidered to truly represent the industrialtechnology of the era, it would be essentialto exhibit such portions removed throughrestoration or models made for exhibit usingthe original materials. In some cases, damagedmembers that need to be replaced can beused effectively for this purpose. In concrete,placement of reinforcement or the high-densityof aggregates are views to be revealed for thefirst time, as finished surfaces are removed.If the present condition is appropriate forrepresenting the industrial technology of abygone period, it may be necessary to preservethe relevant portion by introducing anticorrosiontreatment and assuring structuralsafety through reconstruction of other areasemploying suitable construction techniques.　The plastered ceiling finish of the WestCocoon House at Tomioka Silk Mill wasin most places severely damaged beforerestoration. Professor Tsutomu Kimura notedafter observing the peeling plaster that thiswas a rare condition that indicates the lack ofunderstanding of Western plasterwork in itsearly days of adoption. Therefore, at the WestCocoon House, a glass ceiling is to be createdright beneath the plastered ceiling, as thoughto place another house within the building, toenable the visitors to view the ceiling closely.3. Composition of the Factory's IndustrialHeritage PropertiesFrom which viewpoint should industrialtechnology at factories be understood? It isneedless to say that major manufacturingmachinery is important. If that is all, wewould only need to preserve such machinery,but this would merely represent the historyof machinery. The significance of a factory asindustrial heritage is that it depicts the entiremanufacturing process of an industry.　What is important in understandingmanufacturing procedures, as Doctor KeiichiShimizu had pointed out, is to understand theflow of materials being turned into productsto be finally shipped out as well as to grasp theflow of essential elements such as industrialwater, fuel, and powers that are indispensablefor production.　In the flow of materials being made intoproducts, delivery and storage occupy a largepart of the process. Materials, half-finishedproducts, and finished products are movedback and forth between the workshop andbuildings for storage, to be finally shippedout to the market. On the second floor of theWest Cocoon Warehouse at Tomioka SilkMill, tin covered partition walls installed for
