December 1911. "3:30 P.M. -- Picking nuts in dirty basement tenement, 143 Hudson Street, New York. The dirtiest imaginable children were pawing over the nuts, eating lunch on the table, etc. Mother had a cold, blew her nose frequently (without washing hands) and the dirty handkerchief reposed comfortably on the table and close to the nuts and nut meats. The father picks now -- 'No work to do at any business.' (Has a cobbler's shop in the room.) They said the children didn't pick near. (Probably a temporary respite.)"
