302 EXPERIMENT STATION RECORD. 



plat.-;, and stock, plans of building's, charts, etc., some of the stations 

 showed models of beets grown with different fertilizers, and the sugar 

 and alcohol obtained from them: samples of grains from diti'iM-cnt sec- 

 tions, and of the soil and rocks of the respective sections; microphoto- 

 graphs of yeasts and bacteria; apparatus for testing agricultural 

 machines, and specimens of plants and seeds grown under various con- 

 ditions of experiment. A number of pieces of original apparatus were 

 shown, among them Bartmann's apparatus for stirring solutions in six 

 beakers simultaneously, and a filter siphon. The station for agricul- 

 tural climatology at Juvisy presented a temperature and rainfall record 

 covering two hundred years, beautiful photographs illustrating the 

 classification of clouds, a section of the soil of the plateau of Juvisy, 

 showing 16 strata, and the work of Flannnarion on the effect of differ- 

 ent colored ravs of light on the development of plants. The station 

 for sericulture at Manosque illustrated the culture of silkworms and 

 the work which it is doing in silk production. The investigations of 

 L. Grandeau on the feeding of cal) and omnil)us horses was illustrated 

 by sample rations, dynamometers, and other apparatus used, and charts. 

 These formed a novel and interesting feature. 



The exhibit of the German stations, which was one of the largest in 

 its class, was shown in connection with the general agricultural exhibit 

 of Germany. The handbook of the latter ga^'e a rev>w of the devel- 

 opment and present status of the experiment stations in Gei-many bj" 

 Professor Nobbe. and a short account of the historv. organization, and 

 lines of work of each station, with an eiuuneration of the material 

 exhibited. This furnished quite complete and systematic data for the 

 German stations, some of the statistics being especially interesting. 

 The total revenue of the 73 stations enumerated is given as 2,244,630 

 marks, or approximately $94,312, 26.8 per cent of which comes from 

 the general government, 2.6 per cent from the provincial government, 

 40. T per cent from agricultural and other societies, and nearly 30 per 

 cent from fees for analysis and control work. 



The Moor station at Bremen exhibited several pieces of special 

 apparatus for the investigation of moor soils, such as the determination 

 of su])stances injurious to plants, absorptive properties, and the free 

 humic acids, and a large collection of photographs showing experi- 

 ments to test fertilizers and various kinds of physical treatmtMit, the 

 deletei-ious effects of perchlorate on rye, etc. The photograplis illus- 

 trating the reclamation of moors were interesting and instructive. 



The Dai-mstadt station showed oi\ly photographs illusti'ating its 

 various pot and field experiments. The Halle station showed appa- 

 ratus for determining phosphoric acid aivd nitrogen on a connuercial 

 scale, and an interesting set of photographs illustrating the results of 

 vegetation expiM'iments on the ([uestion of nitrification in the soil and 

 the treatment of lianiyard manure. The station for plant prot«H'tion
