Creek station. The Third Iowa reconnoitered within 5 miles of Fayetteville to-day; there was no sign of any movement; but the people speak of continued augmentation of the enemy's forces.

The mill run by Colonel Dodge--Blackman's Mill, 16 miles southeast of this place--was burned last night by the rebels, and they also burned considerable forage in that region.

Other matters of interest will be communicated when we meet at Sugar Creek, which must be soon, as I desire our camp to be arranged in view of some defenses.

I am, general, &c.,

SAINT LOUIS, MO., March 3, 1862.

To the POLICE COMMISSIONERS,

Saint Louis, Mo.:

GENTLEMEN: The city policemen are in the habit of arresting negroes "as runaways," and frequently arrest, or attempt to arrest, the servants of the army officers, who are put to the trouble of obtaining orders to prevent their servants from being taken from them on the very eve of their leaving the city. This is exceedingly annoying to officers under marching orders. They do not desire to be considered as resisting any civil process. It is not their intention nor the intention of the military authorities to interfere with or prevent the owner of a slave from pursuing his legal remedies to recover his slave, but I have to request that hereafter the city police be confined in their arrests of negroes as "runaways" strictly to such negroes as may be in a legal manner claimed by his or her owner. Negroes must be arrested "as runaways" or fugitives from labor by a writ issued from a court having jurisdiction of the case. This is necessary in order that the slave may have the opportunity to plead the act of Congress of July, 1862.

I am, very respectfully, gentlemen, your obedient servant,

BERNARD G. FARRAR,

Provost-Marshal-General.
