The food is well cooked, and is served at 10 a. m. an 3 p. m., thus: The prisoners are divided into messes of fifty and each placed under the charge of one of their own sergeants. At the proper hours these squads are marched successively under a guard to the kitchen, receive their food in buckets, and take it back to the wards for distribution.

When the prisoners arrive their names are registered and their money taken from them and deposited with a quartermaster, to be returned upon their release. This is done by the warden generally; it is stated in the presence of a commissioned officer, but I infer that the officer is merely present without personally scrutinizing the performance of the duty. I am informed by the quartermaster in charge of such funds that applications have sometimes been made by prisoners for money alleged to have been delivered up, but which he had never received. I hear from Major Parkhill, post quartermaster, that a Frenchman of some respectability, who was released by General Winder, complained that he had given up $150 in U. S. Treasury notes and only received back $50. Charges of this character may be false; they come generally forma mendacious people, but a matter in which the good faith of the Government is involved should not be left entirely under the control of a subordinate employees. A commissioned officer of character should not only be present when the prisoners are deprived of their money, but he should closely supervise the business in each case.

There is a hospital attached to these prison, in which two surgeons, three assistant surgeons, four contract physicians, three hospital stewards, and ten disabled soldiers (nurses) are on duty. A number of prisoners are also employed as nurses. There were 620 patients (mostly wounded), apparently as well served as our sick. The cooking is done by captured negroes.

In the last seventeen months 50,418 prisoners have been receive here; 9,904 have been treated; 2,885 have died of those treated in hospital; 1,870 were wounded men; of the deaths 148 were from wounds.

General Winder, I believe, had a general supervision over all the military prisons of the country; this is not exercised by Major Carrington. I am informed by Major Turner that nobody knows now exactly how many prisoners of war we have in confinement in the different prisons, and that no officer is charged with the management of the whole. It would seem to be important to give to some officer the exclusive control of all the prisoners of war in the Confederacy.
