326 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.84 



Now that these questions are measurably solved, the station is extend- 

 ing out more and more toward the study of insects injurious to fruit, 

 and these studies are followed in all of the Federal agricultural 

 establishments. 



As early as 1909, the Association of Teachers of Agriculture in 

 Switzerland published a little book by Doctor Faes entitled " The 

 Maladies of Cultivated Plants and Their Treatment." It is a handy 

 little book of 250-odd pages, with illustrations, and treats many forms 

 of insects and plant diseases. 



In German Switzerland there are three institutions, namely 

 " Schweizerische Versuchsanstalt fiir Obst- Wein- und Gartenbau, 

 Wadenswil ; Schweizerische landwirtschaftliche Versuchsanstalt, Oer- 

 likon/Zurich," and the Entomological Institute of the Federal Poly- 

 technic School (O. Schneider-Orelli, Director) at Zurich. The 

 results of the work of these stations are published in the Agricultural 

 Yearbook of Switzerland and in the Swiss Journal for Orchard and 

 Vine Culture, either in the form of annual reports or as original works. 

 There is also the agricultural establishment of Liebefeld at Berne, 

 w'hich concerns itself with apiculture and diseases of bees. 



As to forest entomology, we must refer to the large work, entitled 

 " The Scolytids of Central Europe," by Dr. A. Barbey, printed at 

 Geneva and Paris in 1921. This is an elaborate folio volume with 

 excellent illustrations of Scolytid work and of the beetles themselves. 

 Doctor Barbey has also published a Treatise on Forest Entomology 

 (Paris, 1925). Although his book was published in Paris, Doctor 

 Barbey is a Swiss. The volume (second edition) covers 749 pages, 

 with 8 plates and 496 text figures. 



There should also be mentioned the fine work on Ic Hanneton by 

 Prof. M. Decoppet, formerly Professor at the Polytechnic School 

 and Inspector General and Chief of the Division of Forests, Game 

 and Fish in the Federal Department of the Interior. This volume, 

 published in 1920, is a quarto of 130 pages, with 8 plates and very 

 many maps. It includes a bibliography of the luiropean cockchafer 

 plagues from 1662 to 1920. 



Quite a large number of papers relating to applied entomology 

 have been published in Switzerland since the publication of Volume 7 

 of the Fauna Helvetica. The work done in German Switzerland has 

 been very good. Since the beginning of the Review of Applied Ento- 

 mology in 1912, 177 papers from Switzerland have been reviewed 

 (down to September, 1929). 



In 1926 there was published in the Anzeiger fiir Schiidlingskunde, 

 Volume 2, No. 9, pages 1 18-120, an important article by Professor
