There is no evidence that Adair in pursuance of his purpose went to London at this time. He did go to New York in 1768 and there in the early part of the following year issued a prospectus, in like manner. While there he visited Sir William Johnson at Johnson Hall. This visit, with subsequent incidents, is shown in a correspondence between Johnson, Gage and Adair which appears in _The Documentary History of New York_, IV, 251-252, 259-262. The letters afford side-lights on our author and his book: Johnson to General Gage: Johnson hall Decr. 10th 1768 “Dear Sir: This letter is addressed to you at the intreaty of the Bearer Mr. Adair, who I am informed was for many years a Trader of first consequence amongst the Cherokees &c. I believe his present Circumstances are very indifferent but he conceives he has a prospect of some advantages in view from the Publication of a manuscript he has wrote on the Manners, Customs & History of the Southern Indians, tending to prove their descent from the Hebrews, which performance shews him a man well acquainted with the Languages, and very Curious in his Remarks. His design is to go for England and (if he may be allowed) to take some Chickasaws with him, & as none of that Nation were ever there he conceives it would be for the public advantage to Shew them the greatness and power of the English. “I apprehend that your Patronage in whatever shape you may please to Countenance his design, is his principal object. If he is worthy of it in any degree my recommendation is needless—His appearance may not be much in his favor and his voluminous Work may rather be deemed Curious than entertaining, but he is certainly well acquainted with the Southern Indians, and a man of Learning tho Rusticated by 30 years residence in a Wild Country—He thinks that I could serve him by mentioning him to you, and I hope that his importunity in consequence of that opinion will apologize for the Liberty I have taken in Giving you this Trouble.” Adair to Johnson, of March or April, 1769: “Sire, About a month ago, I did myself ye pleasure of writing to you, both in complyance to yr kindly request, and my own ardent inclination. And, now, I re-assume it, returning you my most hearty thanks, for your civilities and favours of each kind.
