STATISTICS AND HISTORY. 



A most interesting account in detail of the 

 German changes in the results of forest management 



Oind in Prussia during the 25-year period 1889- 



Prussian 1913. including, in some directions, data 



Prog^ress. for the whole of Germany, and of other in- 



terests than forest economy, is given by 

 Semper. 

 During these 25 years the population of Prussia increased 42 

 per cent, (in all Germany 40%), but a shifting of population 

 has taken place, by which the proportion of agricultural popu- 

 lation has decreased from 42 per cent, to 29 per cent, of the total 

 population, as a result of industrial development. This has led 

 lately to a revival of colonization schemes, the forest administra- 

 tion, especially in the Eastern provinces, being active in that di- 

 rection. 



Emigration, which in the early eighties still ran to over 850,000 

 per year, in the period 1907-11 had dropped to 125,000. The 

 general prosperity of the country may be gauged by the savings 

 bank accounts, which for all Germany doubled from 1900 to 

 1910 to $4200 million dollars ; for Prussia, trebled in 22 years 

 to $2600 million. 



Wages have risen (at the Krupp works in Essen) from 88 cents 

 to $1.32, or just 50 per cent. 



Agriailtiu'ol production has increased considerably more than 

 the population and has made Germany independent of importa- 

 tions in meat and bread, so that, while e.g. in 1885 to 1890 im- 

 ports of rye were 9 per cent, of the consumption, at present ex- 

 ports of 5 to 8 per cent, are reported. The yield per acre has in- 

 creased for different crops from 30 to 60 per cent, and are at 

 present 1600 lbs. in rye, 1850 in wheat, 1800 in barley, 1600 in 

 oats, and 9320 in potatoes, the latter figure due to the dry years,
