numbers of insects and by their economic importance to man. Then 

 he went to Switzerland, where he associated with certain famous 

 entomologists and where he saw in the Concilium Bibliographicum at 

 Zurich some of the bulletins of the Division of Entomology of the 

 United States Department of Agriculture. This experience opened 

 up the field of applied entomology to him. He had never heard of it 

 before, and in 1897 he published his first paper, entitled (translated) 

 " Troublesome Guests of the Insect World." He was appointed in 

 the spring of 1898 as Zoologist at the newly established Station for 

 Plant Protection in Hamburg, and his duty was to examine plants 

 and plant products coming from the United States, to prevent the 

 introduction of the San Jose scale. He had many difficulties there. 

 The organization was dominated by a botanist, Doctor Brick, and he 

 was not allowed to sign his own manuscripts. During the early part 

 of the present century Reh constantly labored to secure a recognition 

 of applied entomology in Germany, and from his work it is probable 

 that many minds were prepared for the movement started by Esche- 

 rich on his return from the United States in 1910 which resulted in 

 the founding of the German Society for Applied Entomology and the 

 many important publications and activities that have come about. 



There is no doubt of the very high quality of the work in economic 

 entomology which is now being done in Germany, nor of the fact 

 that they are rapidly publishing valuable results. Important new books 

 are constantly appearing, and will continue to do so. An excellent 

 one was published in 1927, on the subject of the insect enemies of 

 stored products. It is by Dr. Friederich Zacher, of Berlin. It covers 

 365 pages, with 123 text figures and 8 very good colored plates. It is 

 the largest and latest general work on this subject, and seems to be 

 thoroughly up to date. Doctor Zacher began his work in this direction 

 in 191 7, and has evidently studied it most carefully and intelligently. 

 The book contains many new pictures illustrating damage. 



Prior to the World War the Germans were doing some good ento- 

 mological work in German East Africa and in other German colonies 

 that no longer exist. The work by H. Morstatt was especially notable ; 

 while F. Zacher, writing in Berlin, published accounts of colonial pests. 

 The work by K. Friederichs on the coconut beetle in German Samoa 

 should be mentioned in this connection ; and F. Zacher published a 

 general review of African cotton insects. 



Fortunately, just as this work is closing there has appeared a very 

 fine two-volume work by Dr. Karl Friederichs entitled " Die Grund- 

 fragen und Gesetzmassigkeiten der land- und forstwirtschaftlichen 

 Zoologie insbesondere der Entomologie." The two volumes cover
