science, but he is responsible for many important discoveries and for 

 a strengthening of the esteem in which all scientific men are held in 

 the eyes of the general public. He is responsible for larger funds to 

 the museums and for governmental appropriations for the support of 

 much scientific work. In this remarkable change Jablonowski has 

 been an important factor, and I was not at all surprised to note the 

 high esteem in which he was held at the Third International Congress 

 of Entomology in Zurich in 1925 and at the Tenth International 

 Zoological Congress at Budapest in 1927. 



As is obvious from this, his administration of his office in Pesth 

 was very successful. He not only speedily established the confidence 

 of the agricultural public of Hungary in the value of his work, but 

 made his name known throughout the Empire and in fact throughout 

 Europe. His early work on the animal pests of sugar beets resulted 

 in a great increase in the growing of this crop and in the number of 

 sugar factories owing to the fact that he discovered how to control a 

 beetle known as Cleonus punctiventris, a species that occurs only in 

 Hungary and southern Russia. He also published two large treatises 

 entitled " The Injurious Animals of Fruit-Trees and Grapes " and 

 " The Protection of the Fruit Orchard." Later he published another 

 work on " The Animal Pests of the Hop." 



As to the Hessian fly, he early advised the late planting of wheat 

 in those parts of Hungary where this insect had become a pest ; and 

 his investigations of Zahrus gibbiis, the larvae of which destroy 

 young grain and the adults of which feed upon the grain before it 

 ripens, showed the value of crop rotation. Other successful investi- 

 gations were carried on, and Jablonowski has behind him a record of 

 extremely fine and successful work. 



To us in Washington he has always been .one of the most helpful 

 of the European workers. In the early part of the century I visited 

 him several times in Budapest, and we grew to be very fast friends. 

 He was the first person to point out to me the overwintering of the 

 larval parasites of the brown-tail moth in the nests of the young 

 larvae ; and owing to this suggestion we were able to import thousands 

 of these winter nests and to establish in this country certain very 

 eflfective enemies of the brow'n-tail moth which have undoubtedly 

 aided greatly in the control of this pest and in the prevention of its 

 spread beyond the region that it inhabits in New England. Then too, 

 when the European corn borer was discovered to have established 

 itself firmly in this country, we appealed to Jablonowski for full 

 information as to this insect in southern Europe. During a desperate 

 time in his country, when the Bolshevists under Bela Kun were in 

 control, he prepared a long and important manuscript that was of
