In Aid of The Great Central Fair,

For The United States Sanitary Commission.

Philadelphia, March 22D, 1864

It is purposed to hold a “Great Fair” in this City, in the first week of June next, on behalf of the United States Sanitary Commission. With this view, we beg leave to address you.

We solicit the sympathy of every true hearted patriot in Pennsylvania, Delaware and new Jersey, and elsewhere, so far as our appeal may reach, to respond nobly and generously to our call. We ask their earnest and untiring efforts and co-operation; and we confidently hope that every county, city, town and village will feel an honest pride in being worthily represented at “The Great Central Fair.”

We would say, in conclusion, that there is a great work before us, and but a limited space of time in which to accomplish it. We would therefore earnestly represent to the ladies the importance of forming themselves, AT ONCE, into Sewing Societies, in every vicinity of country or city; the more effectively and agreeably to work for the approaching humane and patriotic undertaking.

We feel every confidence that our loyal countrywomen, always ready to work in a good cause, even at the cost of great personal exertions and sacrifices, will not now be slow in ministering, through INDIRECTLY, none the less CERTAINLY, to the wants and sufferings of the noble defenders of their country’s flag.
