composition of the support. A manuscriptmap entitled A Plan of the Province of NewBrunswick, executed on a very thin, brittlepaper, was tightly rolled around a woodendowel (Photo 4). The paper had beenimpregnated with an oil-resin mixturein order to make it translucent. While itcould be possible to remove the resinouscompound with solvent treatments in orderto restore some strength and flexibilityto the paper, tests indicated that such atreatment would alter the translucency ofthe paper. Instead, in order to preserve thetranslucent quality of the impregnated paperand to provide added strength, the brittlepaper was lined with a lightweight Japanesepaper. The map was gently humidified, andthe lining was prepared. The treatment wascarried out on a large light table, whichfacilitated the placement of multiple mapcomponents and detached fragments.A restrained lining technique waschosen to facilitate the alignment of tearsand fragments. Referred to as a terylene orDacron lining 1 , a polyester fabric is used asa temporary support for the lining paper. Agreat advantage of this lining method is thatthe object is lined face-up and transmittedlight may be used to facilitate tear alignment.Photo 5a Terylene and Japanese paper lining are adheredto the light tablePhoto 5b Positioning the map fragments on a Mylar sheetusing the light tablePhoto 5d Brushing the map through the Mylar onto theliningPhoto 5c Transferring the map on the Mylar carrier to theliningPhoto 5e Removing the Mylar58
