IN the account given last year in NATURE of the 1934 British Industries Fair, it was described as the largest national trade fair in the world. The 1935 Fair, which opened in London on February 18, is even larger than its immediate predecessor—a reflection, it may be hoped, of increasing prosperity in the nation's trade. At Olynipia the lighter industries occupy every available square foot of exhibiting space, while the textile and furnishing sections at the White City are larger and more fully representative than ever. The main object of the Fair is, of course, a commercial one; the most welcome visitors are buyers. But the Fair has, undoubtedly, an educational value, for it presents to the visitor, in an attractive and accessible form and in a condensed space, a general survey of the results of the nation's manufacturing industry. Moreover, every changing phase in the tastes and habits of the people is reflected in such a collection of manufactured articles as is to be found at the Fair. The removal of much that is tedious and unnecessary from domestic work is indicated by the increased popularity of chromium-plated ware and of stainless steel and stainless silver articles, and by the space allotted in the Fair to the exhibition of devices for domestic mechanisation. The exhibition in larger quantities of open-air equipment of all kinds indicates that increasingly the leisure of the people is being used in healthy pursuits.
