state Riley. He was unable to resist the pressure, and Comstock was 

 retired to his old university position, but received from the Depart- 

 ment of Agriculture a salary of one thousand dollars a year for 

 one year during which time he was instructed to work at Ithaca upon 

 an addition to his studies of the Coccidae. 



Since that time Comstock has remained at Cornell, except for 

 occasional annual journeys during the first few years after the 

 founding of Stanford University, to give courses of lectures out 

 there. He taught actively at Cornell until his retirement in 1914. 

 Since then he has worked on his books and has traveled rather 

 extensively, visiting Europe and Hawaii and other places. His 

 work after he left Washington was not devoted especially to economic 

 entomology. He achieved a reputation as a great teacher, surrounded 

 himself with a number of excellent young men, and did important 

 work in insect morphology. His " Manual for the Study of Insects," 

 published in collaboration with Mrs. Comstock, was a standard book 

 for many years. In 1925 it was succeeded by his " Introduction to 

 Entomology " which bids fair to remain standard for as many more. 

 In the meantime he has published several good books — one entitled 

 " Insect Life," another " How to Know the Butterflies," and still 

 another and much more important one, " The Spider Book." 



In the latter part of 1926 he had a paralytic stroke, and has since 

 that time remained almost entirely motionless in bed. His voluntary 

 motor faculties have remained functionless, but the vital processes 

 have seemed unimpaired, and he remains, during his waking hours, 

 apparently perfectly conscious and with an actively working mind. 

 I saw him in the summer of 1928, and he seemed, to look at him, in 

 better health than I had ever known him — not at all emaciated ; on the 

 contrary, with a healthy plumpness. He is still living at the date of 

 this writing (January, 1930). 



Not long after returning to Cornell, Comstock found a very intelli- 

 gent young man among his advanced students, and to him he gradu- 

 ally turned over all the work in economic entomology. This young 

 man was M. V. Slingerland who made in his short life a great im- 

 pression on American economic entomology and who would have 

 done very much more had he lived. He died, however, in 1909. He 

 worked out anew the life histories of some well known insects with 

 remarkable results and his pioneering work in the use of photogra- 

 phy in illustrating injurious insects was very effective. 



A few years later, Vernon L. Kellogg, who had graduated at the 

 University of Kansas in 1889, went to Cornell to take postgraduate 

 studies in entomology, and accompanied Comstock on one of his
