CIRCULAR.] OFFICE COMMISSARY-GENERAL OF PRISONERS,

Detroit, Mich., July 7, 1862.

The following regulations will be observed at all stations where prisoners of war are held:

1. The commanding officer at each station is held accountable for the discipline and good order of his command and for the security of the prisoners, and will take such measures as will best secure these results. He will divide the prisoners into companies, and will cause written reports to be made to him of their condition every morning showing the changes made during the preceding twenty-four hours, giving the name of the "joined," "transferred," "deaths," &c. At the end of every month commanders will send to the commissary-general of prisoners a return of prisoners, giving names and details to explain alterations. Where rolls of "joined" or "transferred" have been forwarded during the month it will be sufficient to refer to them on the return.

2. On the arrival of prisoners at any station a careful comparison of them with the rolls that accompany them will be made and all errors on the rolls will be corrected. When no roll accompanies the prisoners one will be immediately made out containing all the information required as correct as can be from the statements of the prisoners themselves. When the prisoners are citizens the town, county, and State from which they come will be given on the rolls under the heads, rank, regiment and company. At the some time they will be required to give up all arms and weapons of every description and all moneys which they have in their possession, for which the commanding officer will give receipts.

3. The hospital will be under the immediate charge of the senior surgeon who will be held responsible to the commanding office for its good order and the condition of the sick. "The fund" of this hospital will be kept separate from the fund of the hospital for the troops and will be disbursed for the sole benefit of the sick prisoners on the requisition of the surgeon approved by the commanding officer. When the fund is sufficiently large there will be bought with it besides the articles usually purchased all articles of table furniture, kitchen utensils, articles for policing, shirts and drawers for the sick, the expense of washing and all articles that may be indispensably necessary to promote the sanitary condition of the hospital.

4. The commanding officer will cause requisitions to be made by his quartermaster on the nearest depot for such clothing as may be absolutely necessary for the prisoners, which requisition will be approved by him after a careful inquiry as to the necessity and submitted for the approval of the commissary-general of prisoners. The clothing will be issued by the quartermaster to the prisoners with the assistance and under the supervision of an officer detailed for the purpose, whose certificate that the issue has been made in his presence will be the quartermaster's voucher for the clothing issued. From the 30th of April to the 1st of October neither drawers nor socks will be allowed except to the sick.

5. A general fund for the benefit of the prisoners will be made by withholding from their rations all that can be spared without inconvenience to them, and selling this surplus under existing regulations to the commissary, who will hold the funds in his hands and be accountable for them subject to the commanding officer's order to cover purchases. The purchases with the fund will be made by or through the
