104 HISTORY OF PHYTOPATHOLOGY 



so known: F. L. Scribner, first federal phytopathologist; 

 B. T. Galloway, first chief of the Bureau of Plant Industry 

 in the United States Department of Agriculture; Erwin 

 F. Smith, the dean of American phytopathologists and 

 father of the science of bacterio-phy topathology 1 ; J. C. 

 Arthur, our greatest rust specialist 2 ; T. J. Burrill, dis- 

 coverer of bacterial phytopathogenesis; G. F. Atkinson, 

 a noted American botanist, and author of several classics 

 in phytopathology 3 ; L. R. Jones, noted for his studies 

 on the etiology and control of potato blights, 4 his inves- 



1 A complete list of Smith's papers on bacterial diseases of plants 

 would be too extensive for these pages. His pre-eminence in the field 

 of bacterio-phytopathology has been fully established by his epoch- 

 making studies on the crown gall, a plant cancer, and by his mono- 

 graphic work on bacterial diseases of plants, Bacteria in relation to plant 

 diseases, three volumes of which have appeared, the first in 1905, the 

 second in 1911, and the third in 1914. 



2 Besides many papers on various taxonomic phases of the rust prob- 

 lem, of which the most important to plant pathology are perhaps those 

 detailing his cultural studies, Arthur is also the author of the rust section 

 of the North American Flora.

 plum pockets. Contribution to the knowledge of the prunicolous

4 His investigations on the potato blight and its control conducted at 

 the Vermont Station extend over a period of twenty years, beginning in 

 1890. This work is concisely reviewed by B. F. Lutfnan, Twenty years' 

 spraying for potato diseases, Vermont Agr. Exp. Sta. Bui. 159. For 

 other important contributions to this subject, see Jones, L. R., et al.
