Among the subjects dealt with by M. Zola in the Rougon-Macquart series, that of the present work,--the development of the great _magasins de nouveautés_--is to me one of the most familiar, for the reason that I have always taken a keen interest in the attire and adornment of women, and in my salad days wrote some hundreds of columns of fashion's articles for English newspapers. And my duties in those days took me not only to the _salons_ of M. Worth, M. Pingat and other _faiseurs à la mode_, but also to the great drapers', for if, on the one hand, I learned in the former establishments what would be worn by royalty, aristocracy and fashionable depravity, on the other, in the huge bazaars similar to "Au Bonheur des Dames", I ascertained what would be the popular craze of the hour, the material which would be seen on the back of every second woman one might meet, and the one or two colours which for a few months would catch the eye at every street corner. All this may seem to be frivolity, but it is on such frivolity that a goodly portion of civilized humanity subsists. I find M. André Cochut, a well informed writer, holding an official position, stating in 1866--a year which comes within the period I am referring to--that there were then 26,000 shops and work-shops in Paris which sold or made (almost exclusively) articles of female attire; and these 26,000 establishments (many, of course, very small) gave employment to nearly 140,000 persons of both sexes, among whom there were 1500 designers. Moreover, the trade of Paris in materials and made-up goods was estimated at 570 millions of francs, or £22,800,000! Under these circumstances that Paris should have claimed the sovereignty of fashion is, I think, not surprising.
