Mary Louise and the Liberty Girls by L. Frank Baum

An hour later six girls met at the home of Alora Jones, who lived with her father in a fine mansion across the street from Colonel Hathaway's residence. These girls were prepared to work, and work diligently, under the leadership of Mary Louise, for they had been planning and discussing this event for several days, patiently awaiting the word to start their campaign.

"Some girls," said Mary Louise, "are knitting, and that's a good thing to do, in a way. Others are making pajamas and pillows for the Red Cross, and that's also an admirable thing to do. But our duty lies on a higher plane, for we're going to get money to enable Uncle Sam to take care of our soldier boys."
