ProiVssor Adams lias been eugagcd for 

 synie years past in an experimental investi- 

 gation into the nature of the movements 

 set vip during the folding and deformation 

 of the roeks of the earth's crust. 



Abstract of h'cpori.— Dr. Adams reports 

 that JIcGill University has provided for 

 his use in carrying on the investigation on 

 the flow of rocks a large room in the base- 

 ment of the new chemical building of the 

 university. In this room )u> has installed 

 the apparatus he formerly had and ordered 

 a third and much more powerful hydi-aulic 

 press, by which pressure up to 120 tons 

 may be secured and nuiintained. if neces- 

 sary, for weeks at a time. Ample provision 

 has been made in the installation of the 

 new hydraulic press, looking to the possi- 

 bility of the extension of the plant in its 

 adaptation to the most varied expei-iniental 

 uses. 



On the completion of the installation Dr. 

 Adams conuneuced the investigation of 

 high ditfei'ential pressures on dolomites 

 from ilaryland, JIassachusetts and the 

 pro\nnce of Quebec. It was foimd that at 

 ordinary temperatures these dolomites 

 coidd be made to flow in the same manner 

 as in the case of the pure Carrara marble. 

 He is now carrying on experiments to as- 

 certain the effect of heat upon the flow of 

 dolonnte. In order to compare the eft'ects 

 produced at high pressures with those pro- 

 duced by lower pi-cssures, the higher repre- 

 senting the condition at lower depths in the 

 earth's crust, experiments 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 water Portland oolite, which is the 

 rock he has selected for further experi- 

 ments on the deformation of limestones 

 when heated, with water passing through 

 them. He has also a.ssembled material to 

 conuuence the study of granite essexite and 



diabase, as typical igneous rucks under 

 very high pressures at ordinary tempera- 

 tures. 



V. K. Vax IIisE, University of Wisconsin, 

 ^Madison, \Vis. For investigating the 

 subject of geophysical research, etc. 

 $2,500. 



In the 'Year Book' for 1902, page 2(i. an 

 extended report was presented on tlie sub- 

 ject of geophysics. As the trustees were 

 not prepared to act upon the project, a 

 further study of the problem was made, 

 at the rerpiost of the executive committee, 

 by Professor Van Ilise, who investigated 

 the subject of geophysical research in fluro- 

 pean institutions and made a report, which 

 is printed in the 'Year Book.'

T. C. Chamberlin, University of Chicago, 

 Chicago, 111. For study of the funda- 

 mental principles of geology. $6,000. 

 Abstract of lie port.— Flans for the con- 

 sideration of the dift'erent phases of the 

 complex subjects of this investigation were 

 arranged Avith numerous collaborators, and 

 details of this collaboration and the results 

 obtained are given in Pi-ofessor Chamber- 

 liu's report printed in the 'Year Book.' 



B.ULEY AViLiJS, U. S. Geological Survey, 

 AVashington, D. C. For geological ex- 

 ploration in eastern China. $12,000. 

 This grant was for the purpose of 

 carrying on a comparative .study of the 

 geologj- of eastern Asia and western North 

 America, by observafions in stratigraphy, 

 structui'c and physiography in eastern 

 China and Siberia, ami by the collection of 

 fossils. ]>articularly with reference to the 

 development of the Cambrian faunas. 



He proposed to begin his in((uirics in the 

 mountain district in Shantung— the Tai- 

 shan— a geological unit of about 4,000 

 .sfpiare miles, where a study could be made 

 of the geology from pro-Cambrian gneisses 

 to the Coal Measures.
