literature for American students. Contrast our condition in 

 the United States with that of Germany as far as publications 

 of an elementary character are concerned." One pathologist 

 writes "I have upon my shelves at the present time fifteen small 

 volumes in the German language treating of plant pathology." 



"There are not the positions open to pathology students 

 that there are in other lines of teaching, since pathology is not 

 taught in high schools, secondary schools, etc. Plant pathology 

 has been taught in a very uninteresting manner. It is peculiarly 

 difficult to teach, one side being pure science, the investigation 

 of the cause of the disease, and the applied side or the application 

 of preventive methods." 



The future centers of training for plant pathology and al- 

 lied agricultural subjects rre bound to be in our great univer- 

 sities. The future centers of activity must be at the experiment 

 stations and kindred places, where it is only a step from the 

 laboratory to the field. 



In summing up these various opinions it seems that if the 

 results of investigations are to be permanent there must be some 

 means of enlarging and correcting the different view-points. 

 If we would have this, a broad, healthful, inspiring cooperation 

 must be instituted, a something to which we give of what we have, 

 and from w-hich we receive stimulating assistance. Back of all 

 his it is to be remembered that there is no fixed course. Each 

 one must blast his own way. The easy things have all been done 

 The hard problems are left.

BOOKS AND CURRENT LITERATURE. 



The Proceedings of the Society of American Foresters, of 

 which a separate volume is now issued each year, contain much 

 material that is quite as interesting to botanists as to profes- 

 sional foresters. Among the papers to which special reference 

 may be made is one by Herbert A. Smith (Vol. Ill, No. 1) on 

 Tolerance and Intolerance of Trees. The author holds that tol- 

 erance has been badly overworked as an explanation of the
