 oise, althoujjh his main service in this field 

 was less to individual students than to those 

 he helped liy his translation of the work of 

 his old preceptor. Professor Karl von Zittel. 



During the last decade Dr. Eastman gave 

 his attention largely to the history of the 

 rer-ent fishes, lie had been the means of 

 luiiiging til tlu> Carnegie Museum a remark- 

 able' collection of these forms from Monte 

 Bolca, and during his sojourn in Pittsburgh 

 he published a descriptive catalogue of them 

 together with various sj^eeial memoirs. So 

 too in his last years he gave free rein to his 

 love for Greek and Eoman literature. He was 

 a constant reader of the natural history of 

 the ancients and was piobably better in- 

 formed in this field than any living author. 



Dr. Eastman's death was a tragic one. 

 Anxious to help in the war, he had re- 



lini|uished his work in the American Museum 

 ami hail associated himself with the War 

 Trade Board in Washington. Here he had 

 worked assiduously for several months. He 

 ii'turned to New ^'ork for a lirief rest, was 

 attacked by the ]ir(>sent epidemic of inilu- 

 en/.a, and had gone to Long Beach hoping 

 for a si)eedy recovery. On the evening of 

 liis arrival, September 27, although suffering 

 with fever, he left the hotel to take the air on 

 the board walk. So far as can be ascertained 

 he wandered away from the lighted part 

 of the walk and fell either from the edge 

 of the walk where the rail was broken, or 

 between loosened boards. The sea was 

 rougii and at that hour the tide extended 

 well beyond this dilajiidated end of the 

 walk, so that in the fall it a))pears that 

 he was stunned and carried out in the surf. 

 It had been the hope of Dr. Eastman, 

 as well as of the authorities in the Museum, 

 that at the conclusion of his work for the 

 United States Government, he would return 

 to the Museum and take in charge the edit- 

 ing of the index volume of the Bihliographti 

 to which he had given the last three years of 

 his life.— Bashford Dean. 



Minerals That Are Helping to Win the War 



(All Ejliihif ill fh( Udll of Mhit')'(ils (if tin- Aiiiiricdii Miiscinii) 



THOSE of us who are constrained to 

 view the amazing spectacle of the 

 World War from this side of the 

 Atlantic are increasingly conscious of the 

 far-reaching effect of this supreme struggle 

 upon every phase of industry and production. 

 Xew and vital problems along many lines 

 present themselves for solution almost daily. 



In few phases of the question of produc- 

 tion are the conditions more pressing than 

 in that which concerns the supj>ly of raw- 

 materials for the manufacture of munitions 

 of war. The term "war minerals" has recently 

 been applied to the ores which produce the 

 metals used in the making of ammunition, 

 ordnance, armor plate, special forgings for 

 motor parts, as well as those essential to the 

 production of tools and apparatus. 



These basic elements of our war inai hinery 

 are featured in a series of war minerals and 



their products just put on exhibition in the 

 hall of minerals at the American Museum. 

 So far as possible this series aims to visu- 

 alize the steps in the development of war 

 munitions, from the ore to the finished prod- 

 uct, and to emphasize the need of estab- 

 lishing an adequate domestic source of sup- 

 ply of ores of the rarer metals, such as 

 mercury, nickel, manganese, chromium, 

 tungsten, vanadium, and molybdenum. 



Under each group of ores and products 

 in the exhibit the application of the given 

 metal or mineral to its specific war industry 

 is indicated, as in the case of molybdenum 

 steel, used in the inner tubes of large guns, 

 which "resists the erosion of the gases de- 

 v(do])ed by smokeless powder." 



Small majts displayed with each mineral 

 in the exhibit show the occurrence of the 

 (ires in the United States, and are accom-
