This is the keystone of the arch.

John Gibson was a man of note and of unblemished character; he was made a general by Washington, and held high appointive positions under Madison and Jefferson; he was also an Associate Judge of the Court of Common Pleas in Pennsylvania.

Throughout his life he bore a reputation for absolute truthfulness.

He was the messenger who went to Logan, heard the speech, took it down, and gave it to Lord Dunmore.

We have his deposition, delivered under oath, that "Logan delivered to him the speech nearly as related by Mr.Jefferson in his Notes," when the two were alone together, and that he "on his return to camp delivered the speech to Lord Dunmore," and that he also at the time told Logan he was mistaken about Cresap.
