“Dear Mr. Hosmer,
Here is a link to a document that I hope helps; it is authored by Harlan Unrau and on page 226, references the November 27, 1850 decision to build a monument.
It has a footnote that references its source as Proceedings of the President and Board of Directors [of the C&O Canal], which are housed at the National Archives. The full reference to the monument is on page 384 of volume 8 (previously vol. H), which reads as follows:
“Recorded- that a marble slab or block of suitable dimensions be prepared and placed in a conspicuous position in the masonry of, or on the line of the canal, with the names of the President, Directors, the names of the Officers of the Company, the names of the State Agents and the date of the completion of the canal to Cumberland inscribed upon it. The cost of the same to be paid out of the Contingent fund.”
