following respectable list, not counting the journals of the lumber trade and other related 

 publications. Those marked with an asterisk (*) are to be found in the library of the Division of 

 Forestry; those marked (t) are considered the best or are most comprehensive; those marked (?) 

 have been discontinued. 



German forealry periodicalx. 



Should the reader wish to collect a library of the most modern thought on any or all subjects 

 pertaining to forestry in Germany the list of books contained in the library of the Department of 

 Agriculture, a catalogue of which has been published, with over 1,200 numbers and probably 2,000 

 volumes, would give him a good selection. 



FORESTRY ASSOCIATIONS. 



Forestry associations thrive better in Germany than in the United States and are of a different 

 character; they are associations of foresters, who practice what they preach. There is no more 

 need of a propaganda for forestry than there would be here for ngriculture, and the discussions, 

 therefore, are moving in technical, scientific, and economic directions. Besides some thirty or 

 forty larger and smaller local associations, there is held every year a forestry congress, at which 

 the leading foresters discuss important questions of the day. 



FOREST EXPERIMENT STATIONS. 



In addition to all these means of education and of advancement of forestry science, and in 

 addition to the demonstration forests connected with the various schools of forestry, there lias 

 been developed in the last twenty years a new and most important factor in the shape of forest 

 experiment stations, which are also mostly connected with the forestry schools. If forestry had 

 a strong and well-supported constituency before, this additional force has imparted new impulses 

 in every direction. 



The first incentive for the establishment of these stations came from the recognition that the 

 study of forest influences upon climate could be carried on only with the aid of long-continued 

 observations at certain stations. Accordingly, during the years 18G2 to 1807, forest meteorological 

 stations were instituted in Bavaria, which, under the efficient direction of the well-known and 

 eminent Dr. Ebermayer, for the h'rst time attempted to solve these and other climatic questions 

 on a scientific basis. The results of these and other observations have been fully discussed in 

 Bulletin 7 of the Forestry Division and are briefly recorded in this report. 



While these stations were continued aud others added in all parts of the country, an enlarge 

 ment of the programme was soon discussed with great vigor, leading (between the years 1870-1870) 

 to the institution of fully organized experiment stations in Prussia, Bavaria, Saxony, Thuringia, 

 Wurtemberg, Baden, Switzerland and Austria following in the same direction ; all of these finally 

 combining into an "association of German forest experiment stations," similar to the association 

 of agricultural experiment stations in our country. Thus the science of forestry, which hitherto 

 had been developed empirically, has been placed upon the basis of exact scientific investigation, 

 the fruit of which is just beginning to ripen in many branches.
