The housework for the foreign-born housewife is often complicated by other factors. One is the practice to which reference has been already made of taking lodgers to supplement the father's wages. In discussing this subject from the point of view of the lodger, it has been pointed out that the practice with reference to the taking of boarders and lodgers varies in different places and among different groups. The amounts paid were not noted there, but they become important when considered together with the service asked of the housewife. Usually the boarder or lodger pays a fixed monthly sum--from $2 to $3.50, or, more rarely, $4 a month--for lodging, cleaning, washing, and cooking; his food is secured separately, the account being entered in a grocery book and settled at regular intervals. Sometimes the lodger does his own buying, but the more common custom is to have the housewife do it. Occasionally he does his own cooking, in which case payment for lodging secures him the right to use the stove. More rarely, as in some of the Mexican families visited in Chicago in 1919, he is a regular boarder, paying a weekly sum for room and board. Just what keeping lodgers means in adding to the duties of the housewife can be seen from the following description of the work of the Serbo-Croatian women in Johnstown, Pennsylvania:[15] The wife, without extra charge, makes up the beds, does the washing and ironing, and buys and prepares the food for all the lodgers. Usually she gets everything on credit, and the lodgers pay their respective shares biweekly. These conditions exist to some extent among other foreigners, but are not so prevalent among other nationalities in Johnstown as among the Serbo-Croatians. In a workingman's family, it is sometimes said, the woman's working day is two hours longer than the man's. But if this statement is correct in general, the augmentation stated is insufficient in these abnormal homes, where the women are required to have many meals and dinner buckets ready at irregular hours to accommodate men working on different shifts. The Serbo-Croatian women who, more than any of the others, do all this work, are big, handsome, and graceful, proud and reckless of their strength. During the progress of the investigation, in the winter months, they were frequently seen walking about the yards and courts, in bare feet, on the snow and ice-covered ground, hanging up clothes or carrying water into the house from a yard hydrant. WOMEN WORK OUTSIDE THE HOME Another factor that renders housekeeping difficult is the necessity of doing wage-paid work outside the home, to which reference has already been made. Women interviewed have repeatedly emphasized the difficulties that this practice creates in connection with the housekeeping.
