to the short-lived Houghton Farm in New York. This position he held 
during the year 1882 to 1883. Professor George L. Goodale, whom 
I wish to thank for some facts regarding Professor Penhallow, says, 
“This experimental farm began its work under the most favorable 
auspices and presented a capital chance for investigations in plant 
life. Professor Penhallow did first-class work at this point, but, 
suddenly, in a spasm of economy, the projector of the enterprise gave 
it up, and sent him adrift.” Professor Goodale offered him the hos- 
pitality of the Harvard Botanic Garden and the University Labora- 
tory, and he also had the summer school class in botany. 
In 1883 he accepted the position of Professor of Botany at McGill 
University in Montreal. Here he had general classes in botany, 
but there was not much opportunity for physiological work. The 
late Sir John William Dawson, the Canadian geologist and naturalist, 
and at that time Principal of McGill University, turned him over to 
palaeo-botany and the little leisure he had was given up to that part 
of the field. He held his position there for twenty-seven years until 
his death. The University conferred upon him the degree of Master 
of Science (M. S.) in 1896, and that of Doctor of Science (D. S.) in 
1904. It was during this period, in 1888, that Boston University gave 
Professor Penhallow the degree of Bachelor of Science (B. S.). 
His published works were written mainly during his life at McGill 
University, and some idea of their extent can be formed from the 
fact that his publications on botanical subjects alone, chiefly relating 
to palaeo-botany, comprise about one hundred and fifty titles, while 
his reputation as a scholar, a director and an organizer is shown in 
the many honorable positions he held in societies and institutions of 
note both at home and abroad. 
During the past few years he was very active in establishing a 
Biological Station at St. Andrews, New Brunswick, and to this task 
he devoted his very best energies and strength. Much of the work 
came during the vacation period and this in connection with his 
regular duties was too much for him. His wonderful physique could 
not endure this strain. 
It was early in December, 1909, that he fell ill, but he manfully 
labored to regain his health which had always been so robust that the 
strenuous climbs and tramps that many shrink from were a pleasure 
and exhilaration to him. He went with his wife in late December 
to South Carolina, and in early spring they returned north to Shel-
