All documents in Box #1030 underwent conservation treatment in January 2017 at the Northeast Document Conservation Center in Andover, MA.

Treatment Summary: Surface soil was reduced using dry cleaning techniques as necessary. The solubility of the inks on twenty-one objects selected for aqueous treatment were tested. The blue"#" and "copied" stamps were removed from 4 objects through the use of organic solvents on the suction table in preparation for washing. Please note: Some of the ink was not solubilized and remains in the paper. The documents were washed in a 30:70 ethanol water combination to reduce acidity, staining and discoloration. Paper patches were removed during the washing procedure. After carefully testing the iron gall ink and confirming the presence of free iron (Fe2+ ), a calcium phytate treatment was performed to stabilize the iron gall ink followed by alkalization with calcium bicarbonate as needed. Treated objects were sized with a 0.5% gelatin solution. Tears and breaks were mended and losses were filled with an appropriate weight Japanese paper and wheat starch paste as needed. Thirty-two objects were humidified and flattened between blotters under moderate pressure as needed. All objects were housed in archival folders and polyester L-sleeves as needed in a 3" archival document box. A spacer was constructed of archival corrugated board to prevent slumping of the documents in the box.
