PLANT PATHOLOGY IN ITS RELATIONS TO 

 OTHER SCIENCES 



In the naming of this association of 

 scientists, The Illinois Academy of Sci- 

 ence,^ there was recognized a very subtle 

 tendency in advancing civilization and 

 modern educational thought. It has often 

 been noted that as civilization becomes 

 more highly developed, it also becomes 

 more complicated, and men become more 

 dependent upon one another. So, too, as 

 knowledge increases in volume and in ex- 

 tent, the fields of study which were 

 formerly quite independent grow closer 

 together, and, new fields opening up, find 

 themselves involved with many others 

 already existing. "We are finding, in fact, 

 that kaowledge is a unit— not a mere as- 

 semblage of disconnected ideas, so that it 

 is advantageous, now and then, to examine 

 a new science, and to discover, in so far 

 as we can, with what other parts of the 

 body of science it may be intimately re- 

 lated. Therefore, it has seemed advisable 

 to consider, this morning, how plant 

 pathology is related to other sciences. 



Plant pathology is one of the youngest, 

 and perhaps one of the least understood, 

 of the recently developed sciences. When 

 considered in its broadest meaning, it is 

 for plants, as medical science is for man, 

 a study of the normal, and of the diseased 

 conditions of the organism. In the nar- 

 rower and more widely accepted sense, 

 however, it deals with the abnormalities

 first regular meeting, held at Decatur, Illinois, 

 February 22, 1908.
