194 MODERN FOREST ECONOMY. 



Experimental stations have been established in connec- 

 tion with many of the Schools of Forestry on the 

 Continent. Amongst other subjects of investigation 

 undertaken by that .in connection with the School of 

 Forestry established in the vicinity of Vienna, is the natural 

 history of the Austrian or black pine, Pinus Austrtaca, 

 Hoess. And along with a monograph on this subject 

 issued last year [1883] there appeared from the pen of 

 Baron F. V. Thuemen the First Part of a Mycological 

 Report, under the title Beitraege zur Kentniss der auf der 

 Schwarzfoehre Vorkommenden Pilze ; and a resume, by the 

 author of that report, of the conclusions arrived at in 

 regard to the fungi infesting this tree, appeared in the 

 Centralblat Fuer Das Gesammte Forsivesen, of which the fol- 

 lowing is a translation : 



' In the study of these fungi great difficulty was 

 experienced from the lack of works supplying what might 

 be considered preliminary information ; in the whole 

 range of literature at command there was found only one 

 reference to the subject, and this not in a German work, 

 but in one published in Denmark, where, within the 

 last ten years, amongst many other foreign trees, the 

 Pinus Austriaca has been experimentally planted on a con- 

 siderable scale. In consequence of this the work had to 

 be commenced ab initio. To this in part,' says the author, 

 ' may be attributed the very small number of fungi 

 described. But this is attributable in a higher degree to 

 the limited number of the parasitic vegetables which infest 

 this tree. It has but a small number of fungi to show 

 compared with the nearly allied species, Pinus sylvestris, 

 P. laricio, P. Corsicana, and, if people will, also P. maritima. 

 It is especially deserving of notice that scarcely any of 

 these fungi which have of late years been declared and 

 acknowledged to be the cause of the appearance of the 

 most injurious diseases, and which have proved everywhere 

 so destructive to the common fir, have thus far, notwith- 

 standing the most careful search, been found on the 

 Austrian pine, Such are the Trametes pini } occasioning the
