Same group as #2595. These boys and many others work late every week night, they said, usually until midnight. On Saturday most of the day and also night. Air is bad; associations are bad, the long hours and confinement are bad. One of the boys told me he was 10 yrs. old, five boys told me 11 years old, three boys told me 12 years old and I could not question many. Late Saturday night, I counted one boy of 10 years, five of 11 years, nineteen boys apparently 12 and 13 years old. Location: Lowell, Massachusetts.
