Belgium established its first experimental station at Gembloux, toward 

 the close of 1871. 



Every one of the agricultural exi)erimental stations is under the 

 direction of, or provided with, experts in chemical science. Many of the 

 results of their investigations are published in the different states, in 

 the official organs of agriculture, and the periodicals of agricultural 

 associations. There is also a large literature in this field. A very inter- 

 esting report of the Central Commission of Prussia, on inquiries into the 

 disease and gTowth of potatoes by the experimental stations, is found 

 in the Annals of Agriculture, No. 1, 1871. The " Composition and 

 nutritive value of pasture-grass " is the subject of another valuable 

 article in Ko. 2 (February and March) of the same. A report on " Trials 

 regarding the porosity of building materials, and the natural and artifi- 

 cial change of air, especially in stables," by the experimental station at 

 Halle, is found in Nos. 10 and 11. The annual report of the central 

 commission of Prussia for experiments in agricultural chemistry, (No. 

 9 (September) of the Prussian annals,) gives detailed accounts of the 

 finances and working of these institutions in 1870. 



Agricultural associations in Germany. — Agricultural associa- 

 tions are organized in Germany in almost all agricultural districts ; 

 they generally combine into a common central association, of which 

 there is one, and in some cases more than one, in a province. Other 

 associations are independent. The local agricultural i^ublished organs, 

 and the experimental stations established by agricultural associations, 

 are under management of the central associations.
