emulate him should be kindled in that mind? We all know 
the teacher, who seems to teach for "what there is in it 
for himself" — such small return of money, social position or 
reputation as seems to be attached to his business ; we have 
seen how he bolsters up his own dead interest in the pro- 
gress of science by sounding phrases about the dignity of 
scientific pursuits. No one recognizes the sham more quick- 
ly or completely than the students in his class room, and 
with the recognition his power as teacher is gone. No one 
can interest another in an intellectual problem in which he 
himself is not genuinely interested. Even if he believes 
himself interested, that is not enough ; self-deception cannot 
save him. His students will feel — vaguely perhaps, but 
surely — that the interest is not real. On the other hand 
the teacher with a genuine zeal for his subject, so simple 
that it never feels the need of self- assertion, already has his 
battle two-thirds won. The student unconsciously detects 
the real article as well as the sham. As it is hopeless to 
deceive students by the parade of simulated enthusiasm, so 
it is unnecessary to proclaim the real one. Thus professor 
Herrick's intellectual honesty and genuine zeal for science 
found an answering note in the minds and hearts of all those 
whose lives touched his. We who knew him felt our own 
ambitions purified and ennobled by the contact. 
Secondly, his remarkable industry emphasized the 
effect of his sincere devotion to science. He was not 
one to tell how much midnight oil he burned or in any way 
indicate the intensity of his labors, but both their quality 
and quantity compelled our attention and we watched and 
found that he rarely spent an idle minute. Not only were 
his working hours long, but intensely active. Many of us 
remember the long quick stride which carried him so rapid- 
ly from task to task ; it was an index to the energy of the 
mental machine within. 
A letter recently received from a former student who 
was for a time a member of his household says : "The 
tireless energy of the man was inspiring. His light was last 
to go out in the home and on going to breakfast early in 
the morning it was no unusual thing to meet professor Her- 
rick returning from the woods or swamp with a supply of
