Collection in context
These records were created by the Department of the Treasury, Bureau of Customs, at the ports of Astoria and Coos Bay, Oregon. They are primary sources digitally reproduced in their original form. The original documents are stored at the National Archives in Seattle, Washington.
Shipmasters and owners signed many types of oaths to comply with customs regulations. When they entered a port, they had to verify that their cargo manifests accurately recorded the ship's cargo. Oaths also confirmed that the vessels were owned by U.S. citizens. If a ship owner lost a vessel and its cargo in a shipwreck, they signed an oath that could be used to file an insurance claim.
