FER, but its editorial management came to TRrEUB with the second 
volume. This has been the natural medium of publication for the 
Mientific work of the Garden, and its files represent well the nature 
and importance of this work. TREuB’s own contributions were exceed- 
ingly varied, not being guided so much by any special phase of botany 
as by the opportunity presented by the tropics. Hence they are cited 
in the literature of morphology, of physiology, and of ecology; and all 
of them are characterized by clear insight and fine presentation. 
His resignation in 1909 was compelled by ill health, brought about 
in connection with the work of enlarging the scope of the Garden by 
making it a part of a Department of Agriculture in Java. He intended 
to live in the Riviera and to prosecute his own studies, but he was forced 
to spend the winter in Egypt, and did not reach Saint Raphael until 
spring. It was a great gratification to him that he lived to see the 
publication of the Festschrift in his honor, to which about sixty of his 
scientific colleagues contributed.—J. M. C. 
DAVID PEARCE PENHALLOW 
(WITH PORTRAIT) 
By the death of Professor D. P. PENHALLOW of McGill University, 
Montreal, at the untimely age of fifty-six, American Botany has lost 
a pioneer and leader in his particular field. Born at Kittery Point, 
Maine, he traveled widely, giving his attention at various times to many 
different activities. One of the founders and for a time the acting 
president of the Royal Agricultural College, Sapporo, Japan, he mani- 
fested after his return from that country an enthusiastic admiration 
arid even love of the Japanese. Domiciled later for over a quarter of 
a century in the Dominion of Canada, he became, without losing his 
American affiliations, so much a part of the academic family of McGill 
University, that he was, for a number of years one of-its Governors. 
It seems probable that the attempt to carry on his scientific work and 
at the same time to do his share of the numerous administrative duties 
which fell to his lot in the country of his adoption, was the primary 
cause of his early decease. 
PENHALLOW’S earlier work in his chosen science was on the ascent 
of sap in wood, and this initial inclination seems to have dominated 
more or less his whole life. After gaining his degree at Amherst, he 
set out at an early age for Japan, where he rendered valuable services 
in connection with the awakening of the scientific activities of that 
remarkable nation. During his stay in Japan, he visited the Aino in the
