Money. But also an accordion "to drive away the dark clouds from my sickroom." I had a vague memory of this letter from twenty years ago, and as she was processing our accession records for scanning, Archivist Amanda Montgomery found it for me.
Here's a post-Civil War letter from veteran Alexander Rider to Dr. Reed Bontecou talking about the difficulties of having a photograph made when he can't leave the house, and asking for an accordion. From the Museum's accession records for SS 2030. Click on the photo to see it larger for reading. Rider was a Private, Company I, 76 Pennsylvania Volunteers, wounded at Pocotaligo, SC on October 22, 1862.
