of 1893. Although it must have been a great disappointment to him, he 

 nevertheless vigorously set to work to make the best of the situation and 

 for several years before the outer quadrangle was built and the present 

 botanical quarters provided, he carried on the work of his department under 

 most discouraging conditions. His laboratories, if such they may have been 

 called, occupied the attic of one of the shop buildings back of the quad- 

 rangle, and were very far from satisfactory either for laboratory or her- 

 barium purposes. However, he began collecting assiduously and before 

 long the nucleus of the fine herbarium which he has left to the university 

 was brought together. 



The flora of California is a peculiarly rich and interesting one and 

 offers exceptional opportunities to the student of the problems of plant 

 distribution. To Professor Dudley, whose work had been especially along 

 these lines, the opportunities for work in his chosen field must have been 

 very enticing, and doubtless compensated in great measure for some of the 

 drawbacks in other respects which he must have felt keenly when he came 

 to Stanford. From the time of his arrival, almost until his death, he made 

 many trips to all parts of the state, collecting zealously and accumulating 

 an invaluable herbarium which remains to remind future students of our 

 flora of his tireless interest in his work. 



Professor Dudley paid especial attention to the flora of the Sierras, 

 and was a recognized authority upon it. CalifcSrnia is pre-eminent in its 

 coniferous forests, which are unrivaled in all the world, and Professor 

 Dudley soon became deeply absorbed in a study of the distribution of these 

 magnificent trees. A considerable number of these are peculiar to Cali- 

 fornia and often of very restricted range, like the familiar Monterey cypress. 

 Professor Dudley studied with especial care the habits and distribution 

 of a beautiful fir {Abies venusta) which is only known to grow in the 

 Santa Lucia range. He made a number of trips to this remote region 

 for the purpose of studying this rarest of the Californian firs. His 

 acquaintance however with all of the coniferous trees was most intimate, 

 and he soon became a recognized authority on the distribution of the Cali- 

 fornian conifers. 



Professor Dudley's interest in the study of the distribution of the 

 forest trees naturally led him to a study of the problems of forestry, which 

 for the past twenty years or so have been arousing so much interest in the 

 United States, and which so deeply concern the welfare of the country. 

 As might be expected, his sympathies were entirely with those who would 

 protect what is left of our magnificent western forests from the reckless 

 exploitation of ignorant or unscrupulous men who have so devastated the
