the courses given in zoology by Drs. John AI. Tyler and F. B. Loomis. 

 In September, 1906, he entered the graduate school at the Massachu- 

 setts Agricultural College, electing entomology, given by Drs. C. H. 

 and H. T. Fernald, as his major subject, and cryptogamic botany and 

 horticulture as his minor subjects. He acted as a state nursery in- 

 spector during the summers of 1907 and 1908. The degree of Ph. D. 

 was conferred upon him in June, 1909, and he at once accepted an 

 appointment with the Bureau of Entomology of the United States 

 Department of Agriculture, working under the direction of Prof. 

 A. L. Quaintance, being detailed to investigate the life histories and 

 habits of cranberry insects in Wisconsin. He spent the balance of the 

 growing season of 1909, and all of the season of 1910, in Wisconsin, 

 with headquarters at Cranmoor. He accomplished a large amount of 

 very valuable work while in Wisconsin and submitted manuscript, 

 now in process of publication by the Bureau, of what appears to be a 

 very complete account of the biologies and habits of the more important 

 cranberry insects in that state, including references to very many 

 other species which he found occurring on the plant. 



Doctor Hooker was promoted one grade January 1, 1911. That 

 spring he was transferred to the Government field station at Vienna, 

 Va., and assigned to work on the Coccinellidse with special reference 

 to determining the comparative economic value of the different species, 

 and also to investigate the biologies and hal)its of the more important 

 species to furnish information for a better understanding of methods 

 which should be employed in their propagation and dissemination to 

 effect the control of noxious species. A good start was made on this 

 work during the year previous to his resignation. 



Doctor Hooker was appointed to the position he held at his death, 

 in October, 1911. He returned to the States on leave of absence during 

 the summer of 1912 and was married on July 3, at Amherst, ]\Iass., 

 to Miss Ehzabeth R. Wiley. Doctor Hooker's body was brought to 

 Amherst, Mass., and interred in Wildwood Cemetery on February 22. 



As a student Doctor Hooker made many friends by his genial ways 

 and quick appreciation of the interests of others. Of his work after 

 leaving Amherst, his chief. Professor Quaintance writes: "He had 

 proved himself to be a very conscientious and faithful worker and 

 inspired the esteem and affection of all who came in contact with him. 

 I regard his untimely death as a very severe loss to the science of Ento- 

 mology, both economic and in its broader aspects." His loss will long 

 be felt bv all those who knew him.
