he had read marvelous accounts, he went to Brazil. There he ob- 

 tained employment in a drug store in the state of Sao Paulo and imme- 

 diately improved his opportunity to study not only the zoolog>^, but 

 also the botany of the region. He quickly attracted the attention 

 of prominent scientific workers and, before long, secured a position 

 with the Commissoa Geografica e Geologica of Sao Paulo, in the 

 division of botany and meteorology. He also accompanied a German 

 scientific expedition on an exploring trip through parts of Brazil. 



His interests had always been along entomological lines and he 

 showed so much promise that his chief, Orville A. Derby, advised him 

 to go to Cornell to study with Professor Comstock. This he did, 

 arriving at Ithaca in the spring of 1903. 



Though Mr. Hammar was handicapped by the facts that he knew 

 practically no EngHsh and that he was wholly self-supporting, his 

 ability and zeal were such that he completed his course with honor in 

 the minimum period and graduated with the class of 1907, taking the 

 B. S. A. degree. He was then appointed assistant in entomology at 

 Cornell, and, carrying on his graduate work in the summer of 1907 

 and the following year, received the degree of Master of Arts in 1908. 



In the spring of 1908 he secured a position as special field agent 

 with the Government Bureau of Entomology and very soon was 

 regarded as one of the most reliable and promising of the young men 

 in the service. He was given assignments of increasing responsibility 

 and on April 1, 1913, was advanced to the rank of entomological assist- 

 ant. From March, 1912, until the time of his death he was in charge 

 of an important substation maintained in New Mexico. 



He had been married, only two months before his death, to Miss 

 Marion Hornor of Parkersburg, W. Va. He and his bride were to 

 have left in a few days to visit her parents in West Virginia and from 

 there they were to sail for Sweden, his boyhood home. 



Mr. Hammar was by no means a narrow specialist but was broadly 

 trained and interested. He was a skilled artist, and used readily 

 seven different languages. While at Cornell he was prominent in 

 student activities. He was one of the organizers and leading spirits 

 of the Cosmopolitan Club and editor of the first Cosmopolitan Annnal. 

 He was also active in the organization of the Agassiz Club, a member 

 of Sigma Xi and of the graduate scientific fraternity. Gamma Alpha. 



His career as a student afforded a clue to the traits which wel-e of 

 such an aid to him in all of his subsequent work, and which promised 

 to put him very early in the front ranks of entomological workers. 

 Well trained, keen and thorough, he possessed in addition, the per- 

 sonal traits which won the esteem and confidence of all with whom he 

 came in contact.
