Series IV. Shipping Papers are divided into two subseries based on the original order. Papers in Subseries A were bundled by ship and voyage, whereas documents in Subseries B were bundled by document type. Wrappers used to bundle were cut open and kept in the folders with the papers. If string was used, it was cut and disposed of. Shipping Papers are comprised of materials relating to vessels owned or charter by Pingree (see Appendix I).
