D. A. McKNIGHT TO S. J. TILDEN
"United States Patent Office,
"Washington, October 24, 1885.
"Hon. Saml. J. Tilden.
"My dear Sir,—A few moments ago I received the two letters which you were good enough to write at my request. I am, as you may surmise, very highly gratified with them. They contain all (and more than all) that I had hoped for, and must certainly accomplish their purpose. And I assure you that I am full of gratitude to you for an interest in my affairs which gives me fresh courage, and which shows me again the great heart that inspired these letters. I only wish that I could thank you in adequate terms, or that I could again do something to exhibit the warm personal regard for you into which my original esteem has developed. If the day ever comes that I can be of service to you, command me.
"With my kindest regards and warmest wishes for your health and happiness, I am,
"Very respectfully and truly,
"Your obedient servant,
"D. A. McKnight."
