The Angus Library has Wheelock's printed receipt from London, which he has dated April 29th 1767. The letter is signed by Robert Keen, secretary, a London gentleman who died in 1793.
It is a marginal note that reveals the make up of the £30.
Another marginal note apologises for a previous acknowledgement being possible misdirected.
Occom preached his way across England from February 16, 1766, to July 22, 1767. He delivered in total between 300 and 400 sermons, drawing large crowds wherever he went. By the end of his tour he had raised over twelve thousand pounds for Wheelock's project.
