planet accessible in vivid and striking form 

 to our people generally. Their assistants 

 have done hazardous and exceedingly in- 

 teresting and important work in the wild- 

 est of the waste spaces of the world. It has 

 been my privilege to journey through the 

 East Central African wilderness and the 

 Brazilian wilderness in company with out- 

 door faunal naturalists — Mearns, Heller, 

 Cherrie, Miller, Loring — and myself to wit- 

 ness the hazard and the high value of their 

 work ; and last winter I visited in Demerara 

 Mr. Beebe's really extraordinary field lab- 

 oratory for intimate biological research in 

 the tropics, and I count it one of the privi- 

 leges and pleasures of my life to have 

 worked with these men.

DEDICATION OF THE CERAMIC ENGI- 

 NEERING BUILDING OF THE 

 UNIVERSITY OF ILLINOIS 



On December 6 and 7, the University of Illi- 

 nois, dedicated its new ceramic engineering 

 building. The dedication exercises were 

 opened at 1.30 p.m. on "Wednesday, December 

 6, by a meeting of the advisory board of the 

 department, followed by a reception in the 

 building, at which all of the laboratories were 

 thrown open to the visiting guests and the uni- 

 versity public. 



On the evening of Wednesday an introduc- 

 tory session was held in the university audi- 

 torium, presided over by Dr. Edmund J. 

 James, president of the university. At this 

 session, Dr. S. W. Stratton, director of the 

 National Bureau of Standards, gave an ad- 

 dress on " The Ceramic Resources of America." 

 This was followed by an address on " Science 

 as an Agency in the Development of the Port- 

 land-Cement Industries," by Mr. J. P. Beck, 

 general manager of the Portland Cement As- 

 sociation of Chicago. Dr. Stratton discussed 

 the organization and formation of the differ- 

 ent types of clay deposits together with their 

 most prominent geological and geographical 



positions in the United States. This was fol- 

 lowed by a discussion of the reactions occur- 

 ring during the burning of clay products. A 

 detailed classification of the various clay prod- 

 ucts fashioned from ceramic materials was also 

 presented. The whole address gave a very 

 clear idea of the great variety and extent of 

 the clay resources of the nation and the multi- 

 fold products which are manufactured from 

 them. 



The second dedicatory session was of a tech- 

 nical nature and assembled on Thursday morn- 

 ing in the university auditorium. It was 

 opened with an address on " The Manufactur- 

 er's Dependence upon Ceramic Research " by 

 Mr. W. D. Gates, president of the American 

 Terra Cotta and Ceramic Company, of Chi- 

 cago. This was followed by further discussions 

 by Mr. Ross C. Purdy, research engineer of 

 the ISTorton Company, and by Mr. L. E. Bar- 

 ringer, engineer of insulations for the Gen- 

 eral Electric Company. Mr. C. H. Kerr, who 

 was to discuss the same topic from the stand- 

 point of the problems of the glass industries, 

 was unable to be present, but sent his discus- 

 sion for presentation. 



The second address of this session was given 

 by Mr. W. W. Marr, chief state highway engi- 

 neer of Illinois, upon the topic " The Use of 

 Ceramic Materials in Highway Construction." 

 This paper was discussed in a very interest- 

 ing manner by Mr. Blair, secretary of the Na- 

 tional Paving Brick Manufacturers' Associa- 

 tion, of Cleveland, Ohio, and by Mr. G. G. 

 Wooley, engineer for the Road Bureau of the 

 Portland Cement Association, Chicago. 



A paper on the topic " Ceramic Products as 

 Structural Materials " was presented by Mr. 

 H. J. Burt, structural engineer, of Chicago, 

 and discussed by Mr. A. V. Bleininger, cera- 

 mic chemist and head of the clay products lab- 

 oratory of the United States Bureau of Stand- 

 ards. 



The last topic for discussion at this session 

 was " The Use of Ceramic Products in the 

 Artistic Embellishment of Buildings." The 

 discussion was opened with a paper by Mr.
