Picket-shooting existing to a fearful extent in the vicinity of Cairo, Ill., General Grant this  day issued the following order to General Paine, commanding the United States forces at Bird's Point: “ I understand that four of our pickets were shot this morning. If this is so, and appearances indicate that the assassins were citizens not regularly organized in the rebel army, the whole country should be cleared out for six miles around, and word given that all citizens making their appearance within those limits are liable to be shot. To execute this, patrols should be sent out in all directions, and bring into camp at Bird's Point all citizens, together with their subsistence, and require them to remain, under penalty of death and destruction of their property, until properly relieved. Let no harm befall these people if they quietly submit, but bring them in and place them in camp below the breastwork, and have them properly guarded. The intention is not to make political prisoners of these people, but to cut off a dangerous class of spies. This applies to all classes and conditions, age and sex. If, however, women and children prefer other protection than we can afford them, they may be allowed to retire beyond the limits indicated — not to return until authorized.”
