In June Sargent is offered a  knighthood

From Sargent to Prime Minster Henry Campbell Bannerman, 1907

The Rt. Honble.
Sir Henry Campbell Bannerman

[from] 31, Tite Street
Chelsea

Dear Sir Henry,

I am deeply appreciate your willingness to propose my name for the high honour to which you refer, but I hold it as one to which I have no right to aspire as I am not one of His Majesty's Subjects but an American Citizen.

Believe me,
With very great respect,
John S. Sargent
