how Dr. Greene loved books: "A new separate department of 

 study like botany or pedagogy is established ; and at once it claims 

 its share of whatever money is available for the purchase of 

 books (which income unfortunately does not increase) and the 

 appropriations for older departments, like history, linguistics, 

 or philosophy, are decreased. In this manner, all maintain a 

 wretched existance on famine allowance." 



Dr. Greene's propensity for buying books never grew less. 

 Throughout his life he sacrificed even the comforts of living in 

 order to buy books, to pay for the printing of his privately pub- 

 lished volumes, and to travel in search of plants. Of his library 

 and herbarium, more will be said later. 



Professor Greene had leave of absence the first half of the 

 year i894-'95, and resigned at the end of the year to accept the 

 professorship of botany in the Catholic University of America 

 at Washington. He left his department in a flourishing con- 

 dition. Howe and Jepson had taken over the course in structure 

 and morphology; Jepson was associated with him in the courses 

 in systematic and medical botany; Davy, now in South Africa, 

 had taken over the economic botany; and Greene himself had 

 added courses in the "History of Botany" and the "Phaneroga- 

 mic Natural Orders." 



Greene's impress upon the University of California remains 

 to this day. Except at Harvard there is no university where 

 the systematic tradition has been upheld as it has been at Berke- 

 ley. To be sure none of Dr. Greene's successors at the University 

 of California are advocates of his methods and beliefs in taxono- 

 my, but the fact remains that Greene was able to establish on the 

 Pacific coast a center of systematic research of such vitality that 

 it has held its own and prospered in competition with the same 

 forces that have elsewhere brought about the decline of syste- 

 matic botany. 



During the ten years at Berkeley, teaching and literary work 

 of course somewhat diminished the time available for collecting. 

 Every vacation, however, was used for a trip to some previously 

 unvisited part of the state. At the time of his removal to 

 Washington, his herbarium had assumed enormous proportions
