Report of Oerebro Chemical Station and Seed-Control Station for 1894, 

 J. "Widen (Oerchro (Sivcden): 1895, pp. 48). — The report contains the usual accounts 

 of chemical and seed control work performed during the year. The following aver- 

 age analyses of fertilizers are given: Superphosphates (26 samples): Water-soluble 

 PjOs 19.10 per cent (18.13 to 20.17), citrate and water-soluble P.O., 20.21 per cent 

 (19.85 to 21.04); Thomas slag (18 samples): Total P>0, 18.18 per cent (16.09 to 

 21.06), citrate-soluble (Wagner's method) 13,90 per cent (11.23 to 15.93), fine meal 

 Sr>.42 per cent (79.40 to 91.90) ; kali-magnesia (10 samples) : K.O 14.86 per cent (13.72 

 to 17.22); Icainit (5 samples) : K:0 12.74 per cent (12,25 to 13.39). — r. w. woll. 



FIELD CEOPS, 



Experiments on the variation in Hanna barley grown in differ- 

 ent places, VON Liebenberci {31itt. Ver. Ford, landiv. Versuchsio. 

 Oestcrr., Id {1895), No. ^, i)iJ. 81-100). — Among- the points covered by 

 the investigation were the weight per bushel, weight of 1,000 kernels, 

 percentage of husk, character of the endosperm, content of protein and 

 of extract. 



The author says that the results corroborate those of earlier experi- 

 ments, and it can be safely stated that with a heavy weight per bushel 

 go a greater weight per kernel, a smaller percentage of husk, a richer 

 content of extract, and finally a greater yield. 



The velvet bean, O. Clute (Florida Sta. Bui. 35, pp. 340-345). — 

 This bean was planted on a poor soil at distances of 1 foot in 3-foot 

 rows. The vines grow from 10 to 20 feet long, yielding at the rate 

 of 10,080 lbs. green forage per acre. The thick and leathery pods con- 

 tained from 3 to 5 large beans irregularly colored with purplish and 

 brownish patches.
