296 CALIFORNIA FISH AND GAME 



Dr. Osji'ood Sinitli is in charge oi the Mono party, and also attaelied 

 to this group are Emmett Hooper, Francis Sumner and Arthur Welan- 

 der. Dr. AValdo Furgason is in charge of the Sierra party, and has the 

 following scientific assistants : Allan De Lacy, Harry Hanson and Hugh 

 Israel. Practically all of the personnel are well-trained fisheries men 

 which "will greatly facilitate securing the necessary biological, physical 

 and chemical data required. 



The Mono-Inyo group is to have two trucks for its use at all times, 

 and only one truck has been assigned to the Sierra party by reason 

 of lack of roads in this region. Pack stock for entrance into inaccessible 

 regions is to be secur&d as needed. 



Each party is completely equipped with nets and seines for making 

 quantitative studies of the density of trout populations in various 

 waters, chemical apparatus for determination of gasses dissolved in 

 water, thermometers, instruments for measuring the food supply in 

 both lakes and streams, air rubber boats for securing data on higli 

 Sierran lakes and many other pieces of equipment. The information 

 obtained will be used to develop balanced stocking policies for the 

 waters in the areas surveyed. 



As noted previously, this work is being conducted as an integral 

 part of the program of the California trout investigations, a coopera- 

 tive project between the U. S. Bureau of Fisheries and the California 

 Division of Fish and Game. Direct cooperation of the stream surveyors 

 is to be had on stream and lake improvement projects inaugurated by 

 the U. S. Forest Service and the California Division of Fish and Game. 



In summary, intensive field investigations are being carried on by 

 a force of 14 men including the waiter, supplied with adequate scientific 

 apparatus for obtaining detailed facts on the waters investigated, and 

 it is hoped that the information obtained will prove most useful in the 

 w'orking out of sound measures for the conservation of trout in these 

 areas. — P. R. Needham, U. 8. Bureau of Fisheries, Stanford University,
