REPORT OF EXECUTIVE COMMITTEE XXXV 



pressures with those produced by lower pressures, the higher repre- 

 senting the condition at lower depths in the earth's crust, experi- 

 ments have been begun on the flow of marble with the 120-ton press. 

 Dr. Adams is also carrying on a series of investigations into the 

 force required to drive w^ater through Portland oolite, which is the 

 rock he has selected for further experiments on the deformation of 

 limestones when heated, with water passing through them. He has 

 also assembled material to commence the study of granite essexite 

 and diabase, as typical igneous rocks under very high pressures at 

 ordinary temperatures. 



C. R. Van Hise, University of Wisconsin, Madison, Wis, Grant 

 No. 71. For investigating the subject of geophysical research, 

 etc. %2 , 500. 



In the Year Book for 1902, page 26, an extended report was pre- 

 sented on the subject of geophysics. As the trustees were not pre- 

 pared to act upon the project, a further study of the problem was 

 made, at the request of the Executive Committee, by Professor Van 

 Hise, who investigated the subject of geophysical research in Euro- 

 pean institutions and made a report, which is printed in the Accom- 

 panying Papers of this report, pages 173-184. 



Geology. 



T. C. Chamberlin, University of Chicago, Chicago, 111. Grant No. 

 31. hor study of the fundamental pririciples of geology . $6,000. 



Abstract of Report. — Plans for the consideration of the different 

 phases of the complex subjects of this investigation were arranged 

 with numerous collaborators, and details of this collaboration and 

 the results obtained are given in Professor Chamberliu's report, 

 printed in the Accompanying Papers in this volume, pages 261-270. 



Bailey Willis, U. S. Geological Surv^ey, Washington, D. C. Grant 

 No. 72. For geological exploration i7i eastern Chiyia. $12,000. 



This grant was for the purpose of carrying on a comparative study 

 of the geology of eastern Asia and western North America, by ob- 

 servations in stratigraphy, structure, and physiography in eastern 

 China and Siberia, and by the collection of fossils, particularly with 

 reference to the development of the Cambrian faunas.
