analyzed was obtained. There appears to be no statement on record as 

 to its value as a fodder, thongii jndj;ing from the analysis it is well 

 worthy of trial." 



A.stra(jahis canadensis is "a stiff, free-growinj?, vetch-like plant, with 

 abundant foliage and spikes of greenish yellow Mowers. It occurs 

 usually on river banks, and sometimes attains a height of 3 ft." 

 The sender of the sample states that "cattle are particularly fond 

 of it." 



Lupines, Clausen (Landir. Wochenbl. ScJiles. HoLst., 41 {1S94), No. 

 39^ pp. 539,540). — At the agricultural school at Heide, yellow, blue, 

 and white lupines have been grown 3 years. In the latest of these 

 experiments the yields of the 3 species at different dates on plats of 

 the same size (area not stated), i^lanted early in May, were as follows:

In the early stages of growth the yields from the blue and white 

 lupines were larger than from the yellow species. Later m the season, 

 however, the yields were practically the same. White lupines sown 

 the middle of August made a growth of about li ft. and a satisfactory 

 yield of green material before frost. Because of their quicker growth, 

 the author recommends the substitution of white and blue lupines for 

 the yellow lupine, which, he states, is the variety most m use in 

 Schleswig-Holstein. 



Experiments with lupines in Belgium, P. de Caluwe {Expose 

 Cult. Expn-. 'lard. G((nd, 189 2-'' 9 3, pp. ;,^i-,i'.9).— Yellow, white, and blue 

 lupines were tested on a sandy soil. White lupines gave the largest 

 yield of organic matter and of grain. The early growth of yellow 

 lupines planted in spring was slow. Blue lupines were much injured 

 by a fungus disease. Wliite lupines planted August 12 made a very 

 satisfactory growth by the middle of November. Experiments with 

 ditleieiit forms of jihosphoric acid were made on lupines. 



On the relation of the composition of soils and of oats 

 produced on them, A. Atteeberg {Kgl. Landt. Alad. Handl. 

 Tidskr., 33 {1894), p,p. 170-190). — The investigation was undertaken to 

 study the relation between soil and product, and to obtain detinite 

 information on the proper methods of fertilization for improving the 

 crop. The paper gives the results of chemical analysis of 90 samples 

 of soil from southern Sweden and the amounts of fertilizing ingredients 

 in outs grown on these soils.
