Subject is exactly cakes and biscuit manufacture
Dorr spent the better part of 1906 and 1907 under contract to Everybody's Magazine to witness and experience the feminization of the trades. She went undercover to work in the accounts division of a department store and as a commercial laundress and then in a number of factories across the country, including manufacturers of shirts, cakes and biscuits, and spun yarn. She struggled with writing for publication and was assigned a collaborator who overtook her command of the project. When the magazine advertised his byline alone for an upcoming series heralded as "The Woman's Invasion," Dorr threatened legal action and her byline was restored. "In the truest sense," she later said, "the articles were not mine."
