Worms or REFERENCE.—The Advertiser's A B 0, 1921 (T. B.

Browne), appears for the thirty-fifth year in a large and handsome volume. The first part of the book contains specimens of successful advertisements and articles on advertising at home and abroad. Following these comes an elaborate directory of the world's Press, skilfully classified and remarkably full and accurate. The familiar work in its new form will be more useful than ever.
