The Committee takes this opportunity of thanking the Hutchinson Trustees for their liberal financial assistance, and of expressing its appreciation of the services so carefully and enthusiastically performed by the investigators, especially those of Mrs. Hammond, who is mainly responsible for the work done in London; of Mrs. Oakeshott, who assisted Mrs. Hammond; of Mrs. Muirhead, who supplied information about Birmingham; of Miss Harrison, who investigated Bristol and the South-West, and Leeds and district; and of Miss Irwin and Mr. Jones, who were in charge of the Scottish enquiries. To the many employers, Trade Union secretaries, and others who were so willing to give assistance to the investigators, the Committee also desires to express its gratitude. Whoever has had experience in collecting and sifting such evidence as is dealt with in this investigation knows how difficult it is to arrive at proper values and just conclusions. And women's trades seem to offer special difficulties of this kind. There are no Trade Union conditions, no general trade rules, no uniformity in apprenticeships, so far as the woman worker is concerned, and the variations in conditions are most striking, even between neighbouring employers drawing their supply of labour from practically the same district, though perhaps not from the same social strata. That difference in strata is in some cases a predominating factor in women's employment, and it everywhere confuses economic and industrial considerations. When to this irregularity of conditions is added a reticence as to "one's personal affairs," due partly to women's lack of the sense that their position is of public interest, and also partly to an unwillingness shown by many employers to disclose the facts of cheap labour, it can readily be seen that the Committee had to exercise the greatest care in its work.
