Xll PARAGRAPHS FOR THE TEACHER 



L. B. Sage, Norwich, N. Y.; Mrs. Mary Rogers Miller, 

 lecturer of the Bureau of Nature -Study in Cornell 

 University. From the botanist's point of view, all the 

 proofs have been read by Dr. Erwin F. Smith, of 

 the Division of Vegetable Physiology and Pathology, 

 United States Department of Agriculture, and his 

 suggestions have been invaluable. Chapters XI and 

 XII are adapted from two papers which were con- 

 tributed to a Farmer's Reading -Course under the 

 author's charge, by Dr. B. M. Duggar, of Cornell 

 University. Two specialists, with whom it has been 

 the author's privilege to associate as teacher and 

 collaborator, have contributed particular parts: Dr. 

 K. C. Davis, the greater portion of Part III, and 

 H. Hasselbring, the most of Chapter XXV. On special 

 problems the author has had the advice of Dr. K. M. 



Wiegand, of Cornell University.
