Mounting Paper Money.
Reading edition
A California member asks how to fix paper money so that it may be examined without having to take it out of envelopes each time. There are two ways of mounting your specimens. The first and most difficult is to take very stiff paper and make a leaf with an opening of the exact size, like the opening in a photograph album leaf. Mucilage the tiniest edge all around, and press till thoroughly dry.
The other way is to cover the four corners, but this prevents the back from being seen. An ideal way would be to have two specimens—one to mount one side front, the other the other side. Rare manuscripts are mounted according to the first method, and then the heavy albumlike leaves are bound into a book.
