A third branch of the trade is "vellum-binding," a name which covers the binding of all ledgers, account books, and bank books, whether bound in vellum or no. The workers engaged in this branch form a separate group, are rarely found on the premises of regular bookbinders, and work chiefly in a separate department in printing houses. The employments of women in vellum-binding are much the same as in publishers' binding; they fold and sew much in the usual manner, the only marked difference arising in the case of large day-books, etc., which are elaborately hand-sewn in frames, each section of the book having a separate guard of linen. It is difficult to draw lines of demarcation between the various workers whose occupations have now been described. In large workplaces a worker will probably be kept at one minute process; the folder will do nothing but fold, the sewer will only sew, the collator only collate, and the inserter only insert. Some forewomen, however, think it better to give the women a change of employment. Gold layers-on and openers-up are always entirely apart from folders and sewers, but collators begin with folding and sewing, and in small houses sometimes combine one or both these processes with collating. The divisions of work between men and women are not made upon any discernible principle of fitness, and except in the case of folding and sewing, which have belonged to women from time immemorial, the various processes began in the hands of men and have been gradually taken up by women. This gradual encroachment has been generally resented and often resisted by the men, and in May, 1893, an elaborate agreement was drawn up by the Bookbinding Trade Section of the London Chamber of Commerce representing the masters, and the secretaries of the men's unions representing the men working in the trade. The women workers were not represented or consulted. The agreement is as follows:-- LONDON SOCIETIES OF JOURNEYMEN BOOKBINDERS. _London Consolidated Society; Bookbinders' and Machine Rulers' Consolidated Union, London Branch; Society of Day-working Bookbinders._ That this meeting of representatives of the Bookbinding Section of the London Chamber of Commerce, with representatives of the Journeymen Bookbinders' Trade Societies, deeming it desirable that a definition of bookbinding should be agreed upon for the delimitation of work to be paid for at recognised rates, hereby agrees that the following divisions or sub-divisions of labour be for the future recognised as the work of bookbinders or apprentices, taking the book from the time of leaving the women after sewing, except wrappering, which is unaffected by this agreement:-- Forwarding, and the following sub-divisions of bookbinding:
