and bibliography additional to that given under the chapter on seed 

 structure, with a glossar^^ The work bears evidence of the author's 

 usual thorough familiarity with the literature of his subject, and in 

 the descriptive part each species is accompanied by notes not only 

 on the author's own suggestions as to methods of extermination 

 but also by those that he has encountered in his extensive reading. 

 Though of varying degrees of quality, the illustrations are such as 

 to facilitate the naming of the species treated, and a map of the 

 State shows at a glance not only the ränge of each species in Iowa 

 but its densest distribution. Trelease.
