was undertaken, the spring of 1893, by the United States 
Department of Labor, by order of Congress ; and as Mrs. 
Florence Kelley, the Special Agent Expert in charge in 
Chicago, resided at Hull-House while conducting the

case was subtracted from the number of weeks in the 
year, the difference multiplied by the weekly wage when 
employed, and the result divided by fifty-two ; then the 
amounts received by the various members of each fam-
