To N. J. Rockwell.

Springfield, January 21, 1846

DEAR SIR:—You perhaps know that General Hardin and I have a contest for the Whig nomination for Congress for this district.

He has had a turn and my argument is "turn about is fair play."

I shall be pleased if this strikes you as a sufficient argument.

Yours truly,
A. LINCOLN.
