264 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.84 



In 1890 there was published (apparently simultaneously in Ber- 

 lin and Vienna) a very good little book entitled (translated) " In- 

 sects Injurious in Agricultural Fields and Kitchen Gardens, Their 

 Life Histories and Remedies." The author's name as published was 

 Gustav Henschel. The book covers about 230 pages, and its titles 

 are arranged alphabetically. It seems to be somewhat of the nature 

 of Kaltenbach's " Pflanzenfeinde." Remedial suggestions, however, 

 are not very abundant or very complicated ; but it is a good, practical, 

 little work. 



In 189s, in Berlin, there appeared a book entitled (translated) 

 " The Injurious Forest and Orchard Insects, Their Life Histories 

 and Remedies, a Practical Handliook for Foresters and Gardeners." 

 The author's name given is G. A. O. Henschel, but he was the same 

 man whose name is given in the preceding paragra])h. The publica- 

 tion of this book was a rather notable incident in entomological prog- 

 ress. It contains more than 750 pages, is well illustrated and accom- 

 panied by synoptic tables. It contains a great mass of useful infor- 

 mation. I have given the date as 1895, but I note on the title page 

 that this is the third, corrected edition. 



An interesting little German work was published at Frankfort in 

 1899, o^^ " Garden Insects." It is by Heinrich Schilling, and is a very 

 good little handbook for persons interested in gardens. 



In an im]>ortant address on " The Develo])ment of Applied luito 

 mology in Germany," delivered before the Third International Con- 

 gress of Entomology at Zurich in July, 1925, Dr. K. Escherich dealt 

 with the international character of the study and spoke with enthusi- 

 asm of the stimulus given to forest entomology by Ratzeburg and also 

 of Taschenbcrg's work and that of Reh. He showed that, aside from 

 forest entomology, the other branches of applied entomology were 

 for many years largely neglected, and this statement a])plied particu- 

 larly to agricultural entomology. It is true that there were a number 

 of agricultural experiment stations and similar institutions, but the 

 object of these stations was mainly to investigate plant biology and 

 pathology and questions of plant breeding and seed control. When 

 damage caused by insects became alarming botanists were consulted, 

 and entomological problems were confided to botanists employed in 

 such research institutions. He spoke well of the work of these men, 

 but said that it was all preliminary, since work of this kind requires 

 a broad zoological training and a knowledge of insects. 



I well remember on my first visit to Flamburg in 1902 that I found 

 Dr. Ludwig Reh working under the recently passed decree prohibiting 

 the entrance of American fruit on account of the danger from the
