tor in Botany, taking the place of Professor Clara E. Cummings 

 during her absence on leave. After the death of Miss Cummings, 

 which occurred in the spring of 1907, he continued his service in 

 Wellesley College, and was advanced, until in 1917, he was made 

 full professor. 



On leaving Harvard, where his interest had led him to specialize, 

 and to write his thesis, in Cryptogamic Botany, he wisely resolved 

 not to suffer his scientific activity to he submerged by the routine 

 of teaching in a woman's college, and to avoid this danger at (he very 

 outset by making himself an expert in some special field of botanical 

 research. 



His selection of this special field, in which he later won distinction, 

 was determined by the presence at Wellesley of the important Lichen 

 Herbarium which had been accumulated by Miss Cummings, and 

 which came under his charge after her death. Having tins her- 

 barium at hand for constant reference, and the unique collection at 

 Harvard within easy reach, he had an unusual opportunity of which 

 he took every advantage; so that, at the t'me of his death, he and 

 his work were well known to lichenologists both in this country and 

 in Europe. 



In everything to which he turned his attention, he was careful and 

 methodical, systematizing his activities so as to make the most com- 

 plete use of his time. Always keeping in mind the necessity for 

 counteracting the narrowing influence of intensive application to a 

 single specialty, he was deliberate in his cultivation of other and 

 varied interests: civic activities in the Wellesley Community: col- 

 lege administration and student interests: extensive and varied 

 reading of general literature, especially in History and the English 

 ('lassies, the thoroughness of which is attested by the copious "mem- 

 oranda from books read" which he has left. 



In addition to these and other factors, his horizon was further 

 broadened by a trip to Europe, during a year's leave of absence in 

 1918, where he made special studies in the lichen collections at Lon- 

 don, Paris, Geneva, Upsala, Helsingfors, etc., and became personally 

 acquainted with various European botanists. 



In the spring of 1919 he received the appointment of 

 Assistant Professor of Cryptogamic Botany and Associate Cur- 

 ator of the Cryptogamic Herbarium at Harvard, and had served
