of pure geology as well as of its application to tlie 

 arts aiid industries. 



The sessions of the Congress are called every 

 three or four years, to continue for about one week. 

 At each session, invitations will be received and 

 the meeting place of the next session determined 

 by the Congress. Excursions constitute an. im- 

 portant adjunct to the sessions and every pos- 

 sible facility is given to the members to study the 

 geologic structure of the country where they are 

 assembled, and of its mineral resources, at a mini- 

 mum expense and under the direction of the most 

 competent guides, with guide books specially pre- 

 pared which serve the double purpose of guiding the 

 excursionists and of presenting a general review of 

 the geology of the country in which the Congress 

 meets. 



Standing committees are organized for the pur- 

 pose of handling questions of general or interna- 

 tional interest demanding international collabora- 

 tion, and the 



Congress may award prizes founded for meritori- 

 ous work within the domain of geologic research. 



The organization should be simple and include: 



A Committee of Organisation, appointed by 

 the host nation, will arrange for that session, its 

 programs and excursions, and its publications. 



Officers. — At the first general meeting of the 

 session, the Committee of Organization shall submit 

 nominations for President and Secretary of that 

 session, and the Council shall submit nominations 

 for Vice-President, for elections by duly accredited 

 members. 



Council. — The Congress is administered dur- 

 ing its sessions by a Council made up of 



1. Members of the Committee of Organization for 

 that session. 



2. Presidents of Geological Societies. 



3. Directors of national and other large geolog- 

 ical surveys. 



4. Oflficers elected by the members of the session. 

 The Council will prepare the order of the day for 



the meetings. 



Standing Committees. — These Committees may 

 be appointed by each Congress to report at the 

 next session, and will be responsible to the Com- 

 mittee of Organization for that next session for the 

 preparation and submission of their reports. 



Membership. — Invitations to each session of 

 the Congress are issued by the committees repre- 

 senting the host nation, to recognized geological 

 organizations, universities, and to national gov- 



ernments. Membership in the Congress is generally 

 restricted to geologists of national standing. 



Tenure of Office.— The Committee of Organi- 

 zation and officers shall hold office untU the close 

 of that session, or until the next committee of or- 

 ganization is formed, to which the documents and 

 files of the Congress shall be transferred. Sub- 

 committees of the local committee shall continue to 

 function until the publications of the session are 

 issued or other business concluded. 



The President of the Congress shall, however, 

 preside at the opening meeting of the next session 

 of the Congress, resigning the chair when his suc- 

 cessor is elected. 



SCIENTIFIC EVENTS 



MOLDING SAND RESEARCH 



Hundreds of thousands of tons of molding 

 and core sands are used annually in the iron, 

 steel and non-ferrous foundries of America. 

 A little of it is re-used; much more might 

 be. Sands are not always correctly selected 

 for specific purposes. Mixing and other 

 treatment can secure improvement. In what 

 ways can foundry practise as to sands be 

 bettered? What economies can be realized, 

 not only in reduced expenditure for sand, 

 but also in less number of lost castings and 

 higher quality of accepted product? 



Last spring, the American Foundrymen's 

 Association decided that thorough study of 

 this subject would be profitable and asked the 

 cooperation of the American Institute of 

 Mining and Metallurgical Engineers. The 

 Institute referred this request to the Division 

 of Engineering of the National Research 

 Council, of which it is a member. Through 

 joint action with the division a valuable di- 

 gest of the literature has been made by Pro- 

 fessor Robert E. Kennedy, of the University 

 of Illinois, and a large committee of foundry- 

 men, engineers and scientific men has been 

 selected, under the general direction of Presi- 

 dent W. P. Bean, of the Foundrymen's As- 

 sociation and the chairman of the division. 



This committee on molding sand research 

 has just been organized with the following 

 officers and executive committee: 

 Chairman: E. A. Bull, consulting engineer, Sewick- 



ley, Pa.
