 fourth in 1901. The present isgue of the book, which is the 

 twentieth, is a new work, it having been rearranged and

 proved itself under certain circumstances. The many 

 investigations of insects and fungi, and the means of 

 attacking them, have resulted in a new literature and 

 more certain means of control. We are beginning a new 

 line of approach to the difficult problem of protection
