the fat conteut of the milk, the results of which iudieated an increase 

 in both per cent and total amount of fat in the milk when cocoanut 

 cake was fed as compared with peanut cake (see Experiment Station 

 Eecord, vol. m, p. C7), and the experiments of the i»revious year to 

 compare the effects of sesame cake and peanut cake for fattening young 

 lambs, were concluded, ^o striking differences were observed between 

 these two materials, but each year the results were slightly in favor of 

 the sesame cake. 



The station has also superintended during the past year a series of 

 cooperative field experiments on forty different farms to study the 

 requirements of the soils. The results were controlled at the station by 

 means of pot experiments. In these trials large pots were filled with 

 soil from each farm and the same kinds and amounts of manure were 

 used and the same kinds of plants were grown as on the larger fields. 

 These pot experiments, showing the effects of different fertilizers on the 

 different soils, are said to have been of much interest and served as an 

 object lesson to large numbers of farmers who visited the station. 



llohenhcim; Seed-Testing Station; Prof. O.Kiirhner, director. — During 

 the year ending October 1, 1890, this station tested 836 samples, repre- 

 senting over 28»>,000 i»onnds of seed, of whi<'h .~>00 sam])les were of clovers, 

 the red ch)vcr predominating. Tlat experiments with red clover, which 

 have been in progress since 1885, to observe the relative yield of clover 

 from dillerent countries, have indicated that in that climate varieties 

 from central Europe (those from Clermany, Austria, 8tyria, r>ohemia, 

 Hungary, Poland, and England) differ very little in desiral)ility, pro- 

 vided they have not come originally from America or southern Europe 

 (Italy, southern France, simthern llungary, etc.). 



In similar plat experiments during 2 years with lucern from Italy, 

 Hungary, Provence, Wiiitcmberg, and America the largest total yields 

 of green fodder from successive cuttings was with Italian lucern and the 

 smallest from American. In 1880 the yi<'ld of the American was 54.:5;{ 

 per cent and in 18DU, 47.55 per cent as large as the yield of the Italian. 

 Where Anunican seed was used about half the i>lants died out the 

 first season. The author believes it to be undesirable that American 

 seed be placed on their market, and warns farmers against sowing it. 

 He states that equally unfavorable results have been obtained with 

 American lucern seed in Switzerland and France. 



Investigations as to the changes in feeding stuffs by souring

 Kellner {Landic. Ver.s. Stat., 39, pp. 105-111).— Y/.wXwv investigations 

 by the author and J. SaAvano seemed to show that the decomposition 

 of the nitrogenous constituents of feeding stuffs in the process of 

 ensiling was, in some cases at least, accomi)nnied by the formation of 

 ammonia, which was partially or wholly driven off during the drying 

 of the material for analysis. Experiments with white clover as to
