amples for the special forms of grain rusts after which, in February 1901, 

 the State granted him a fund of 10,000 Kronen because of these studies. 

 The question of rust which is also of the highest significance in Australia 

 led in 1888 to the annual meeting of a Congress of Members of the Austra- 

 lian Colonies which, for a considerable number of years, published an official 

 report, "Rust in wheat Conference," 



In Germany, Sorauer's "Zeitschrift fiir rilanzcnkrankheiten" was fol- 

 lowed in 1892 by C. v. Tubeuf's Forstlich-naturwissenschafiliche Zeit- 

 schrift" which devoted especial attention to plant diseases. In 1898 the"Kgl. 

 bayrische Station fvir Pflanzenschutz" was founded with von Tubeuf as di- 

 rector. Besides this, reports in the collective work, "Just's botanischer Jah- 

 resbericht," published since 1873, became much more abundant, since a 

 greater number of periodicals now included the subject of plant diseases in 

 their programs. Among these belongs first of all the "Centralhlatt fiir Bak- 

 teriologie, Parasitcnkundc und Infektionskrankhciten" issued by Uhlworm 

 and Hansen, as also "Hedwigia," edited by Hieronymous and P. Hennings, 

 the "Botanische Centralhlatt," elaborated by Lotsy, also Biedermann's 

 "Centralhlatt fiir Agriculturchemie," edited by Kellner, the "Naturwissen- 

 schaftliche Zeitschift fiir Land-und Forstwirtschaft" by von Tubeuf and L. 

 Hiltner and the "Practische Blatter fiir Pflanzenhau und Pflanaenschutz" 

 by L. Hiltner. We find thorough reports, especially on tropical cultivated 

 plants, in "Tropenpflanzer," Zeitschrift f. tropische Landvvirtschaft, by O. 

 Warburg and F. Wohltmann as well as in its "Beiheften" (supplements) 

 which form the organ of the "Kolonialwirtschaftliches Komitee zu Berlin." 

 In the German East-African colonies, Zimmermann is especially active in 

 pathological fields as is shown by his "Mitteilungen aus dem hiologisch-land- 

 wirtschaftlichen Institute Amani." In Austria the "Zeitschrift fiir das Land- 

 wirtschaftliche Versuchsivesen in Oesterreich" was founded in 1898. In the 

 following year P. Nypels began a series of publications under the title "Mal- 

 adies des plantes cultivees" Bruxelles. In 1900, v. Istvanffi published the first 

 volume of the "Annales de ITnstitute Central ampelologique Royal Hongrois" 

 as the report of the Central Vineyard Institute which had been placed under 

 his direction. Here also especial attention was paid to diseases. The same 

 is true also of the "Jahresberichte der Kgl. Lehranstalt fiir Obst-,Wein-und 

 Gartenbau" published by Gothe and later by Wortmann in Geisenheim a. Rh. 

 and the annual reports of the "Deutsch-schweizerische Versuchsstation fiir 

 Obst-Wein-und Gartenbau zu Wadensweil," Zurich, revised by Miiller- 

 Thurgau. 



This list of periodicals which in part review German and foreign litera- 

 ture and in part publish original articles, gives an insight into the unusually 

 rapid growth of material which necessarily demands a unified summary in 

 some collective work. Hollrung devoted himself to the working out of such 

 a summary and since 1899 has been publishing a "Jahresbericht iiber die 

 Neuerungen und Leistungen auf dem Gebiete der Pflanzenkrankheiten," 

 Berlin, publishing house of Paul Parey.
