WORKS or REFERENDE.—The Musical Directory, 1921 (Rudall, Carte, 8s. net),

is in its sixty-ninth year. It is mainly a list—a very, long list—of instrumentalists, professors and traders, but contains also a short account of musical institutions and an obituary.----The Royal -Blue Book -for January, 1921 (Kelly's Directories, 10s. 6d. net), appears as punctually as ever in its hundred and ninety-eighth edition. It is commendably accurate and well printed ; the addition of the telephone number to each name and address saves the user a great deal of time.
