IOWA ACADEMY OF SCIENCE Voi.. XXVII, 1920 
SUMMARY 
1. Plant pathology is a comparatively new subject and the sub- 
ject matter and teaching methods are not so well organized as 
in the older sciences. 
2. The layman knows less about the subject matter than about 
other sciences which are easily transmitted by word of mouth. 
3. Some elementary facts of plant pathology should be taught 
in our public schools because the greater part of our agricul- 
tural population receive education there. 
4. Our public schools are doing practically nothing towards pre- 
venting an annual loss of one and one-third billions dollars 
to thirteen of our most important crops. 
5. Better pedagogy should be applied to the teaching of plant 
pathology. 
a. Let the course be concerned with little about many par- 
asites rather than much about few. 
b. Let the course be adapted to the class of students. 
c. Definite questions or objects should be given the students 
whereby the laboratory periods may be devoted to observa- 
tion and investigation. This will stimulate research work. 
d. Definite summaries or conclusions should be given to all 
work. There should be answers to the objects or questions.
