Lincoln, Abraham, 1809-1865.
Hon: Wm. Martin Springfield,
Dear Sir: July 31. 1851

Yours of the 29th. is received. The present operator here says, that the operator who was here on Jany. 25. 1851 is C. P. Rosser; and that he has no knowledge of his present whereabouts---that previous to being here, he had been in the Telegraph office at Burlington, Iowa; but that he knows nothing of him since he left here. This is all I can learn. Yours as ever A. LINCOLN
