Women of Boston are lending a helping hand in the drive for peach stones, which are being used by the Government in the production of gas masks. This Tableau was arranged to help in the campaign. In the first gas masks of World War I, it was initially found that wood charcoal was a good absorbent of poison gases. In about 1918, it was found that charcoals made from the shells and seeds of various fruits and nuts such as coconuts, chestnuts, horse-chestnuts, and peach stones performed much better than wood charcoal. These waste materials were collected from the public in recycling programs to assist the war effort. Photo taken by Underwood and Underwood, September 23, 1918.
