coming years a series of volumes, to be called perhaps 
Ethnomycological Papers, and, at the end of the road, 
there may be a new edition of our original work, re- 
shaped, simplified, with new evidence added and the 
argument strengthened. 
It would give me pleasure to enumerate the names of 
those to whom we are indebted, but how tedious the 
roll call would be for you who are obliged to listen! There 
is one name, however, that in this audience I must cite. 
For more than ten years, we have been collaborating 
closely with Professor Roger Heim, Membre de |’ Insti- 
tut, and on all matters mycological he has been our guide 
and teacher. For these many years, he has been the di- 
rector in Paris of the Laboratoire de Cryptogamie and, 
even longer, editor of the Revue de Mycologie. More 
recently, he has also borne the burden of directing the 
Muséum National d’ Histoire Naturelle, that renowned 
center for advanced teaching and research in the biologi- 
cal studies, one of the glories of French culture. But 
these titles to academic distinction, though themselves 
of the highest order, do not tell you the story. Vast as 
is his learning and his experience in field and laboratory, 
sound as is his judgment in the vexed problems that you 
mycologists face every day, formidable as he is in po- 
lemic, it is as a rare human being that I commend him 
to you. Patient with the beginner, inspiring as a teacher, 
model of generosity toward others, prodigious worker in 
field and laboratory, and classical stylist in the French 
language, who could be more delightful whether in his 
published writings, or as correspondent, or as companion 
in the field? In the presence of Roger Heim, the time- 
worn conflict between science and the humanities fades 
away. Onesenses that the field of science for him is merely 
the New World that civilized man, the exponent of the 
humanities, is exploring and assimilating. What guardian
