FIELD CROPS. 491 



on plats manured with commercial fertilizers in various comhinations. The yields 

 are tabulated. The author concludes that the later plantings in June and early July 

 are the most protitahle. 



Grasses and forage plants, S. M. Tkacy (Missi.'isipjji Sta. Rjd. lS9'>,pp. 41-44). — 

 This is a republication of matter found in the Annual Kejiort of the station for 1893 

 (E.S. R.,0,p.807). 



The Jack bean {Canamlia eiisiformis) has been grown, ])roducing 30 to 40 bu. of 

 beans per acre on a thin soil. Its value as a fodder plant has not yet been determined. 



Cornstalks shredded in October and baled in November showed lu) signs of molding. 

 An analysis (food constituents) is given. 



Exotic vs. native fodder plants and grasses, W. Tyson {A(jI. Jour. Cape Colony, 

 9 {1S9G), Xo. 22, pp. 570, 571). 



A useful oat grass, J. H. Maidex {Ayl. Gaz. N. S. Wales, 7 {1S96), No. 9, p. 561, 

 pL 1). — Notes are given of an oat grass, Aniaopogon avenaceua, said to be valuable for 

 pasturage in sterile, stonj" regions. 



Lime and lupines (Dent, landiv. Fresse, 23 (1S96), Xos. 91, p. S09, figs. 4; 92, p. S16, 

 figs. 0). — The author concludes that where calcium carbonate is present in the soil to 

 the extent of 0.46 per cent it has an injurious effect on lupines. Phosphate of lime 

 and magnesium carbonate are even worse, 0..5per cent of the latter preventing devel- 

 opment. One per cent of Ca.;(P04)2 kills the lupines and 10.5 per cent works injuri- 

 ously. Calcium sulphate was least injurious of the lime compouiuls. "The injurious 

 effect which calcium carbouate exercises on the growth of lui^ines can be prevented 

 either by kainit or potassium nitrate or by both together.''

 (Fiililiiig's laudw. Ztg.,45 {189G), No. 4, pp. 132-1S5). 



Thomas slag and kainit on oats, P. Petersen (FUhling's landw. Ztg., 45 {1896), 

 No. 4, pp. 140, 141). — The yield of oats on marsh laud, plowed in the fall and har- 

 rowed in the spring with 268 kg. per hectare of Thomas slag and kainit, costing 

 18.85 marks ($4,712), produced an increase of 146.82 marks (.$36,705); manured with 

 568 kg. of the foregoing fertilizers, costing 40 marks ($10), the yield was increased 

 by 174.65 marks ($43,662), showing that a rational application of commercial fertil- 

 izers under the jireseut unfavorable conditions can in many cases still be made to pay. 



Oats, fertilizer test, C. F. Curtiss (Iowa Sta. llul. 32, p. 463). — An application 

 of a combination of nmriate of potash, gypsum, lime, salt, and wood ashes, in 2 

 amounts per acre, failed to show any effect in preventing the oats from lodging. 



Varieties of oat3, C. F. Cuunss (Iowa Sta. Bid. 32, pp. 4r,3-46o). — Of 7 varieties 

 under trial the largest yields were given by Golden, Black Russian, and Calgary 

 Gray.

Separating sunflower seeds from their heads, C. 0. Ormsbee {Anier. Agr. {mid. 

 ed.), 1896, Sept. 26, p. 266). — The apparatus used consists of a wooden Avheel 2 in. 

 thick, through which nails arc driven. The sunflower heads are held against the pro- 

 jecting nails, which biush off the seeds. 



The geographical distribution of tobacco culture and the amount produced, 

 P. Darmstadteu {Inaug. Diss. Tfallc, 1S96, ]ip. U'.i; ahs. in Hot. Centli!., 68 {/896]. No. 

 4, i)p. 122, 123). — The author gives tlie total production of the world at 916.6 million 

 kg. ; of the United States, 240 million kg. ; P>ritish India, 175 million ; Russia, 70 mil- 

 lion ; Austro-IIungary, 65 million; China, 50 million, and Germany, 35 million.
