6 PROCEEDINGS ENTOMOLOGICAL SOCIETY 



of age, who had been an agent of the Entomological Commis- 

 sion and afterwards of the Division in the study of the cotton 

 caterpillar in Mississippi. He lived at Holly Springs, in that 

 State, and was much interested in entomology. He was at that 

 time in Washington on a visit in connection with the cotton cat- 

 erpillar work. The judge was a fine man and made many 

 friends among the entomologists here. He is probably still alive, 

 although I have not heard from him since September, 1905. 

 He wrote me at that time from Pachuta, Miss., relative to 

 mosquitoes. He stated in this letter that prior to 1858 to 1859 

 mosquitoes were unknown at Holly Springs, Miss. They were 

 carried there by the new Mississippi Central Railroad. The 

 judge, in IS/6, caught the first Stcyomyia at Holly Springs 

 and took it to be a new species of Culex. Now mark an inter- 

 esting thing: in 1853 Holly Springs did not quarantine against 

 the fever, and refugees came there ; persons with the fever 

 were brought there, and got well or died without communi- 

 cating the disease; in the scourge of 1878, however, Holly 

 Springs being known as an immune place, people swarmed in 

 there and 'yellow fever patients were brought, but, as just 

 shown, the Stcgomyia had been brought in by the railroad, and 

 the population of Holly Springs was more than decimated. 



Mr. 1). P. Mann is still with us in Washington. At that time 

 he was Assistant Entomologist, and was engaged .largely in 

 work on the Bibliography of Economic Entomology. 



Doctor Morris I have already spoken of. At that time he 

 was well above 80 years, and very stout and florid, with per- 

 fectly white hair and smooth face. He was then pastor emer- 

 itus of a Lutheran church* in lialtimore. He had done no 

 actual entomological work for many years, but was still greatly 

 interested in the subject and full of anecdotes of the earlier 

 entomologists. 



While I was writing these words this morning the door of 

 my office opened, and in came old Professor Cyrus Thomas, 

 84 years of age, but mentally as active as ever. He came in to 

 suggest the idea that certain non-migratory locusts, after a 

 succession of dry seasons, grow longer wings and become 

 migratory. And lie went on to say (mark the coincidence), 

 "J- Ci. Morris came into my laboratory once years ago, when 

 Darwin's book on The Origin of Species was first making such 

 a stir, and while he was objecting to the whole idea of evolu- 

 tion, I told him this about the grasshoppers; and he said, 

 'Thomas, what arc we coming to?'
