On reaching home day before yesterday, I found your letter of the 15th. I regret to say I can not be with you on the 4th of Sept. I amPage  357 under prior obligation to attend a meeting of our friends at Galesburg on that day, if I can possibly leave our courts, which will then be in session.

Stand by the cause, and the cause will carry you through. Yours truly,

A. ``LINCOLN''.
