PERIODICAL LITERATURE 



SILVICULTURE, PROTECTION, AND EXTENSION 



Under this suggestive title, V. A. E. Daeke 

 Milestones traces the development of entomology from ear- 



in liest times in an interesting mariner. 



Bntoniological While insects play a role in the early literature 



History of Chinese, Egyptians, Greeks, and Romans, to 



which references are made, an attempt to de- 

 scribe and classify them is not found before 330 B. C, when Aristotle, 

 most astonishingly successful, grouped the known animals, including 

 insects, and for 1,800 years entomological work was based on this clas- 

 sification, until Linne, in 1758, published the tenth edition of his Sys- 

 tema Naturae, with the binomial nomenclature fully established, which 

 is the starting point for modern entomology. Then follow the more 

 or less epoch-making works in Europe during the eighteenth century of 

 Geoffrey, Fabricius, Labreille, Cuvier, and an increasing host of others. 



In America, out of an amateur society of students of natural history 

 founded in Philadelphia in 1812 the beginnings of entomological study 

 arose. Through the efforts of Thomas Say, the publication of a jour- 

 nal was undertaken in 181 7 by the society, then called the Academy 

 of Natural Sciences (Philadelphia), and he became the father of Amer- 

 ican entomology; but the foundation of economic entomology may be 

 credited to Dr. W. T. Harris, with his report on the insects of Massa- 

 chusetts injurious to vegetation, in 1841, several editions of which were 

 published. The names of Asa Fitch and C. V. Riley are the most 

 prominent in bringing this phase of entomology to the fore, which has 

 produced about 100,000 works and is being discussed in over 500 peri- 

 odicals. 



The development of forest entomology in particular is dated from 

 1881, with the publication of Bulletin 7 of the U. S. Entomological 

 Commission on insects injurious to shade and forest trees, which in its 

 revised form (1890) became the well-known volume of A. S. Packard. 

 Dr. Felts' four volumes are also mentioned in this connection and a 

 number of European authorities. 



The balance of this excellent article is taken up by a recital of other 

 branches of economic entomology, especially the medical entomology,
