All this time her dependence for hospital comforts was upon the Sanitary Commission, for though the regiment was performing the duties of a garrison it was not so considered by the War Department, and the hospital received none of the furnishings it would have been entitled to as a Post Hospital. Most of the hospital bedding and clothing, as well as delicacies of diet came from the Sanitary Commission, and a little money contributed from private sources helped to procure the needed furniture. Mrs. Barker found this "camp life" absorbing and interesting. She became identified with the regiment and was accustomed to speak of it as a part of herself. And even more closely and intimately did she identify herself with her suffering patients in the hospital.

On Sundays, while the chaplain was about his regular duties, she was accustomed to have a little service of her own for the patients, which mostly consisted in reading aloud a printed sermon of the Rev. Henry Ward Beecher, which appeared in the Weekly Traveller, and which was always listened to with eager interest.

The chaplain's quarters were close by the hospital, and at any hour of the day and till a late hour of the night Mr. and Mrs. Barker could assure themselves of the condition and wants of any of the patients, and be instantly ready to minister to them. Mrs. Barker, especially, bore them continually in her thoughts, and though not with them, her heart and time were given to the work of consolation, either by adding to the comforts of the body or the mind.

In January, 1864, it became evident to Mrs. Barker that she could serve in the hospitals more effectually by living in Washington, than by remaining at Fort Albany. She therefore offered her services to the Sanitary Commission without other compensation than the expenses of her board, and making no stipulation as to the nature of her duties, but only that she might remain within reach of the regimental hospital, to which she had so long been devoted.

Just at this time the Commission had determined to secure a more sure and thorough personal distribution of the articles intended for soldiers, and she was requested to become a visitor in certain hospitals in Washington. It was desirable to visit bed-sides, as before, but henceforth as a representative of the Sanitary Commission, with a wider range of duties, and a proportionate increase of facilities. Soldiers were complaining that they saw nothing of the Sanitary Commission, when the shirts they wore, the fruits they ate, the stationery they used, and numerous other comforts from the Commission abounded in the hospitals. Mrs. Barker found that she had only to refuse the thanks which she constantly received, and refer them to the proper object, to see a marked change in the feeling of the sick toward the Sanitary Commission. And she was so fully convinced of the beneficial results of this remarkable organization, that she found the greatest pleasure in doing this.

In all other respects her work was unchanged. There was the same need of cheering influences—the writing of letters and procuring of books, and obtaining of information. There were the thousand varied calls for sympathy and care which kept one constantly on the keenest strain of active life, so that she came to feel that no gift, grace, or accomplishment could be spared without leaving something wanting of a perfect woman's work in the hospitals.

Nine hospitals, in addition to the regimental hospital, which she still thought of as her "own," were assigned her. Of these Harewood contained nearly as many patients as all the others. During the summer of 1864, its wards and tents held twenty-eight hundred patients. It was Mrs. Barker's custom to commence here every Monday morning at the First Ward, doing all she saw needful as she went along, and to go on as far as she could before two o'clock, when she went to dinner. In the afternoon she would visit one of the smaller hospitals, all of whose inmates she could see in the course of one visit, and devote the whole afternoon entirely to that hospital.

The next morning she would begin again at Harewood, where she stopped the day before, doing all she could there, previous to two o'clock, and devoting the afternoon to a smaller hospital. When Harewood was finished, two hospitals might be visited in a day, and in this manner she would complete the entire round weekly.

It was not necessary to speak to every man, for on being recognized as a Sanitary Visitor the men would tell her their wants, and her eye was sufficiently practiced to discern where undue shyness prevented any from speaking of them. An assistant always went with her, who drove the horses, and who, by his knowledge of German, was a great help in understanding the foreign soldiers. They carried a variety of common articles with them, so that the larger proportion of the wants could be supplied on the spot. In this way a constant distribution was going on, in all the hospitals of Washington, whereby the soldiers received what was sent for them with certainty and promptness.

In the meantime the First Heavy Artillery had been ordered to join the army before Petersburg. On the fourth day after it left the forts round Washington, it lost two hundred men killed, wounded and taken prisoners. As soon as the sick or wounded men began to be sent back to Washington, Mrs. Barker was notified of it by her husband, and sought them out to make them the objects of her special care.
