SHIP MAIL FROM ST.THOMAS - CHRISTIANSTED - FREDERIKSTED AND ST.THOMAS - FREDERIKSTED - CHRISTIANSTED

Mourning cover canceled Christiansted February 28. The cover is a rare use of commercial nature and was sent during the time when the St. Croix Post Offices had depleted their stock of 1 cent stamps. There are only two known morning covers with a bisected stamp. Note “via Bassin” - the letter is sent from St.Thomas via mailbox and therefore not cancelled in St. Thomas. Cancelled upon arrival in Bassin (Christiansted).

This letter was likely sent with the mail schooner “Vigilant” on an overnight trip to Christiansted. There - a transit postmark Christiansted April 1 was added on the back - before it continued by mule cart to Frederiksted. Here a second arrival cancel was struck. The letter is sent from St.Thomas March 30.
These postmarks clearly define the DWI post office routing.
Note the inverted frame.

St.Thomas February 10 sent to Bassin (Christiansted) via ship to Frederiksted - continued by mule cart to Christiansted.

Backstamped February 12 - first stamped Frederiksted and then Christiansted.
