than of a general nature. This is especially obvious in the treatment of such 
diseases as apple rust and pear blight. The illustrations are poor. Such figures 
aS 29, 32, 40, 69, 76, 83, 86, 92, 98 are not worthy of publication. Throughout 
the book there is a tendency to present various conflicting ee si argu- 
ments concerning a given disease, with the result that often th 
if any, are buried or obscured. This really is the result of the status of pathol- 
ogy, of insufficient knowledge of the diseases in question, but the value of such 
presentation to the student: and especially to the practical grower is doubtful. 
sgtietg a central New York viewpoint and interest, the book may be said 
0 give a very complete presentation of what is known of fruit diseases, with 
saat lists of references to original sources of information. It is, as the 
authors announce, the first American text to deal wholly with diseases of fruits, 
and here for the first time are brought together with comprehensive discussion 
many obscure and little-known diseases. The facts presented are well selected, 
and the book — a valuable addition to the literature of plant diseases.
