With the outbreak of the war Professor 

 Clarke became actively interested in problems 

 of defense and economic preparedness.. He was 

 appointed a member of the ISTational Research 

 Council and was chairman of the subcommittee 

 on road materials and a member of the com- 

 mittee on camp sites and water supplies. He 

 was also chairman of the committee on high- 

 ways and natural resources of the Maryland 

 Council of Defense. 



Professor Clarke made numerous contribu- 

 tions to geological literature, his work being 

 confined largely to the Cretaceous and Tertiary 

 formations of the Atlantic Coastal Plain and 

 the Carboniferous deposits of the central Appa- 

 lachian region. Professor Clarke's chief 

 paleontologieal interest was centered in the 

 Echinoidea, to the elucidation of which group 

 he published several monographs. One of his 

 monuments will be the series of reports of the 

 Maryland Geological Survey, which set a new 

 standard for state publications both as to sub- 

 ject-matter and book-making. The systematic 

 reports in which he was most interested will 

 be of perennial service to science. 



He was a member of numerous clubs includ- 

 ing the University, Maryland, of which he was 

 a vice-president, Baltimore Country, Johns 

 Hopkins, and City Clubs of Baltimore and the 

 Cosmos Club of Washington. 



He was married October 12, 1892, to Ellen 

 Clarke Strong, daughter of the late Edward 

 A. Strong, of Boston, and had four children, 

 Edward Strong, Helen, who was recently mar- 

 ried to Captain H. Eindlay French, Atherton 

 and Marion, all of whom survive him. 



Professor Clarke's administrative ability 

 and professional attainments are largely re- 

 sponsible for the extensive development of 

 Maryland's mineral resources and his loss will 

 be severely felt in all quarters. He was always 

 keenly interested in the educational value of 

 the work of the various state bureaus which he 

 directed and had just finished writing a geog- 

 raphy of Maryland for school teachers. At the 

 time of his death he was engaged in writing a 

 report on the underground waters of the state 

 and another on the coals. 



SCIENTIFIC EVENTS 



THE ASIATIC ZOOLOGICAL EXPEDITION OF 



THE AMERICAN MUSEUM OF NATURAL 



HISTORY 



Dr. Henry Fairfield Osborn, president of 

 the museum, has received news from Mr. Roy 

 C. Andrews, who is in charge of the expedi- 

 tion. The principal work of the expedition 

 was done in remote regions of the province of' 

 Yunnan, China, where no white man had ever 

 been seen before the explorer and his party 

 entered that region. Mr. Andrews is accom- 

 panied by Mrs. Andrews, who is the ofiB.cial 

 photographer of the expedition. The party, 

 since it has been in Yunnan, has ridden 2,000 

 miles on horseback and made camps in 107 

 different localities varying from 1,700 to 15,- 

 000 feet above the level of the sea. Mr. 

 Andrews says in his report, which is dated at 

 Hui-Yao, May 23, 1917: 



The active field work of the expedition ceases 

 to-morrow, exactly one year since it began by our 

 first trip up the Min Eiver from Foochow — a trip 

 which was interrupted rather seriously by the re- 

 bellion, but which gave us some very interesting 

 experiences. We have as results the following: 

 2,100 mammals, 800 birds, 200 reptUes, 75 skele- 

 tons of mammals, 8,000 feet of motion-picture film, 

 150 Paget natural color photographs, 300 black 

 and white negatives. Our attention to the subject 

 of mammals has, I believe, yielded the largest col- 

 lection ever taken out of China by a single expe- 

 dition. We visited first the northern alpine coun- 

 try along the Thibetan frontier where we were 

 seldom below an altitude of 9,000 feet and col- 

 lected as high as 15,000 feet. The mountains 

 among which we were working were tremendous, 

 reaching as high as 18,000 feet. In this region we 

 were frequently with natives who had never seen a 

 white person. The northern trip occupied some 

 four months and we then started on a long jour- 

 ney southward to the Burma border where we col- 

 lected in regions only 1,700 feet above sea level, 

 where, of course, we found a totally different 

 fauna. Thus the collection covers a wide range of 

 climate as well as actual distance. Our large mam- 

 mals include seven gorals (Nemorhacdus) from the 

 Thibetan region and four serows (Nemorhacdus) 

 — all complete with accessory material for group 

 mounting. On the Burma frontier we collected 

 twenty-five gorals — a perfectly splendid series, all 

 from one mountain and of all possible ages from 

 just born, young to very old males and females.
