PUBLICATIONS. 



Demand for the quarterly inagazinc, (,'aliforxia Fish and Game, 

 continues so great that the edition has now reached 7000. It is now the 

 oldest publication of its kind in the United States, most others having 

 been discontinued during the war. An attempt to clean up the mailing 

 list during the spring of 1922 did not materially reduce the size of 

 the mailing list. 



Every number issued in 1921 was a special number, attention being 

 given to salmon, history of the Commission, hawks and to the sardine. 



The first two numbers in 1922 were also special numbers, that of 

 January being a (jame Refuge number, and that of Api-il being a 

 Hatchery number. A complete list and index of the publications of the 

 Fish and Game Commission since its establishment in 1870 appeared 

 in the April. 1921, number. The Hawk number, (July, 1921.) con- 

 tained two colored plates and many other illustrations designed to 

 correct the usual misunderstanding as to the value of California 

 hawks. The 96-page Sardine number, the material for which was 

 furnished by the State Fisheries Laboratory, has been in great demand 

 and the supply is now nearly exhausted. The valuable historical and 

 statistical data contained in the Hatchery number (April. 1922) will 

 become more and more valuable in years to come. Attention should 

 also be called to a series of reports by Professor J. 0. Snyder of Stan- 

 ford University, on results of the Commission's salmon mai'kint: experi- 

 ments. Volume 7, (1921) contains 286 pages and 9)} illustrations, 

 together with complete reports and index. Analysis shows 26 general 

 articles and more than 150 notes, all relating to fish and game ainl ils 

 conservation in California. Separates of the more imporlant articles 

 have been secured for distribution. 



Two additions have been made to the .series of Fish Bulletins, as 

 follows : Fish Bulletin No. 4, "The Edible Clams, :Mussels and ^lollnsks 

 of the Pacific Coast," by Frank W. Weymouth; an-l Fish Bulletin^ 

 No. 5, ''A Key to the Families of :Marine Fishes of the West Cojist." 

 by E.G. Starks. A new series of i)ublications to be known as Circulars 

 has been started with the appearance of Circular No. 1. entitled 

 "Changes in Oil T^sed fo?- Frying Sirdines," by Harry \l. i'.c;inl. 

 The plan is to place in this series small techuic;d papers of interest 

 only to certain groups.
