The origin of these lines (who did the ruling?) has yet to be confirmed. However, the multiple addressee’s, the various colored ruled lines, the type’s of ruling, and at least 2.5 years of use, suggests that the Providence Post Office put the lines through multiple panes. These “control marked” panes would then have been disseminated to individual or institutional (see Brown University covers) account holders, where they were affixed to covers & delivered the PO. The Providence PO then accepted them as unused (uncancelled) stamps, & applied their postmark (otherwise the stamps would have been deemed used) and put them in the postal stream.
It does not seem plausible that the Providence P.O. would allow 3¢ panes to be ruled by multiple account holders in various inks with various implements out of their jurisdiction, and then to re-accept them as proper payment on covers. And where is the time saving for an account holder or institution that needs to stamp hoards of mail? It is more feasible for a patron to pay a small fee to the Providence P.O. to obtain “control marked” panes, where the post office clerk would have applied these with generic writing implements. Curiously, there are examples of more than one ruled line (red & black) being used both horizontally and vertically (see covers #10 & #11a) on a stamp on cover. Could this be the P.O. clerk’s way of denoting different account holders?
With regards to Brown University, this academic institution did not open an on-campus P.O. until 1926. It seems plausible that enough mail went from Brown University (school, faculty, students) that they needed to set up an account with the Providence P.O. to use their “control marked” panes (was this an attempt to stop pilfering or misuse or simply for convenience). The stamps were almost certainly applied at Brown University.
It is also feasible that Brown became an unofficial branch of the Providence P.O. & sold stamps & delivered letters to the Providence P.O., essentially providing a “carrier” service & had a stock of stamps available. This makes it work far simpler than having the Brown “agent” collecting cash & letters to take to the Providence P.O. to buy special ruled line stamps which he/she then stuck on the Brown letters. Otherwise, there would be no need for ruled-line stamps. From the other on-cover examples, it remains to be determined if they can be tied to an industry or institution in the Providence area.
Dr. Chase made the following observation: “Providence R.I. “Precancelled” by red crayon pencil line across sheet before cutting into”. Interestingly, he refers to the lines as a “precancel”, whereas on the Sweetland cover shown above, he refers to these lines as a “control”. It is my belief that Dr. Chase examined the red ruled lines on piece initially and formulated the “precancel” theory. At a later date, it would appear that he came across or was presented the Sweetland cover with double-ruled black pencil lines and the “control marking” theory was born.
One last point, why do we not find examples of this “control mark” being used prior to 1855? It should be noted that 1855 was the year that compulsory prepayment went into effect on April 1st. Welcome B. Sayles, the Providence Provisional Postmaster, most likely enacted this pre-mailing “control mark” process over this two year period until the new system of prepayment was firmly in place.
