Gulyaev (1949), and of several others. A number of articles and special editions were published for the many workers employed in the cultivation of protective forest plantings, in particular by A. Prisyazhnyuk (1949a) and I. Brezhnev (). In the brochure of I. Brezhnev 30 species of rust fungi parasitizing on woods and brushwood are described in detail and prevention measures are indicated. The articles of V. Gulyaev (1954) and O. Komirna (1952) are concerned with the results of mycological investigations of young forest belts. A brief acquaintance with the works on forest phytopathology, in particular those on the rust fungi harmful to forests, already indicates the insufficiency of the investigations carried out. Well investigated forest diseases are few. Many districts of the USSR, characterized by unique plant combinations, have not been investigated at all. This applies to the vast Siberian taiga areas and the large forests concentrated in the southern mountainous districts of the USSR. The absence of any data for these districts renders difficult the work on forest pathology needed for the proper exploitation of these large forest areas. 21.
