In addition to the field laboratories, through the cordial coopera- 

 tion of the University of California, both the biologist and the chemist 

 of the Committee have the privilege, for Committee work, of the ex- 

 tensive facilities of the University laboratories in their respective 

 sciences. 



Four test stations are maintained by the Committee, where test 

 specimens of wood treated with different oils or oil fractions are now 

 under regular observation, in exposure to borer attack. These stations 

 are at State Harbor Commission Pier No. 7, San Francisco, at the 

 Oakland Mole, the Mare Island Navy Yard, and Crockett- Eight sa- 

 linity stations are maintained, at Avon, Bulls Head Point, Martinez, 

 Port Costa, Crockett, Black Point, Greenbrae and Tiburon, from which 

 samples of water, in some cases at both high and low tide, are taken 

 and analyzed for salinity. 



National Re.seai-^h Council Cooperation 



The San Francisco Bay Marine Piling Committee has initiated the 

 project approved by the Executive Committee of the American Wood- 

 Preservers' Association which has resulted in the organization of a 

 special committee on marine piling investigation by the National Re- 

 search Council, which will thus be able to act as the guiding and cor- 

 relating center for widely distributed investigative activities in this 

 direction which are contemplated by cooperating agencies at many 

 marine centers of the United States, as well as to form a medium 

 of contact between such activities in the United States and other 

 countries. In furtherance of that project this Committee has enlisted 

 for its speciafically scientific activities the service of an Advisory 

 Committee composed of men of the highest scientific rank and attain- 

 ments, appointed by the President of the University of California from 

 the faculty of that institution; which will provide for this work the 

 authoritative scientific guidance required as a condition of its spon- 

 sorship by the National Research Council. This Committee is com- 

 posed of the following members: 



E. C. Lipman, Professor of Soil Chemistry and Bacteriology, Chair- 

 man. 



C. W. Parter, Associate Professor of Chemistry. 



C. Derleth, Jr., Dean, College of Civil Engineering. 



J. S. Burd, Professor of Agricultural Chemistry. 



C. A. Kofoid, Professor of Biology and Assistant Director of the 

 Scripps Institution for Biological Research. 



Walter Mulford, Professor of Forestry and head of the Division of 

 Forestry. 



D. R. Hoagland, Associate Professor of Agricultural Chemistry, 

 Secretary.
