26 ANNUAL REPORT 



not prepared to make any extended remarks at this time. He 

 might, however, refer to the importance of knowing the proper 

 methods of fighting our enemies, the noxious insects. There 

 were two methods of destroying them, the natural and the arti- 

 ficial. 



Insects did not come and spread over very large fields with- 

 out being favored by certain conditions, such as climatic in- 

 fluences, a lack of enemies, or by the present. method of growing 

 as much as possible one kind of food. When, for instance, we 

 cultivate nothing but wheat, the Hessian fly and chinch bug in- 

 crease beyond measure. If we grow nothing but potatoes the 

 potato beetles increase inordinately. Among the natural reme- 

 dies were to be included our friends, carnivorous beetles and 

 parasitic wasps, both valuable for the destruction of other in- 

 sects. 



He had noticed near Perham the week before a species of dra- 

 gon fly that seemed to be making attacks upon the grasshoppers. 



Every farmer should study this subject of entomology and be 

 able to recognize his friends at once among the insect species. 



Insects could be destroyed by the use of coal oil, Paris green, 

 and other insecticides, but the most important thing, perhaps, 

 was the matter of co-operation ; farmers should come together 

 and fight them in a concerted manner. 



President Elliot. We have with us another gentleman that 

 has had a great deal of experience in the way of landscape gar- 

 dening. I refer to Prof. Cleveland, and will ask him to favor us 

 with just a few remarks this afternoon. 



REMARKS BY PROF. H. W. S. CLEVELAND. 



Ladies and Gentlemen: This is entirely unexpected to me, 

 but I feel that I have some right to speak to a horticultural so- 

 ciety by virtue of former occupations. 



I was for many years engaged especially in fruit culture in the 

 State of New Jersey. I took a very active part, more than forty 

 years ago, in organizing the New Jersey Horticultural Society, 

 of which I was the secretary for a great many years. I was also 

 a member of the Pennsylvania State Horticultural Society. 



It is many years, however, since then, or since I have had 

 much practical experience with horticulture. I have been be- 

 tween thirty and forty years engaged in my profession of land 

 scape gardening. For five years past I have been endeavoring
