Captain JOHN C. KELTON, Assistant Adjutant-General:

CAPTAIN: In compliance with directions from the general commanding the department, I have the honor to submit the following brief remarks concerning the condition of the district under my command:

Both railroads are undisturbed since the penalty inflicted in Marion County. Of course there is much excitement and uneasiness among the people since the affair at Springfield, but I think from the best
