 ?13.78 per acre, 43.7 cts. per bushel ; hay from $11.90 to $13.25 per acre and from 

 $5.70 to $5.86 per ton ; corn silage from $21.97 to $30.75 per acre and from $1.91 

 to $5.36 per ton ; turnips from $28.98 to $45.56 per acre, from $1.86 to $2.50 per 

 ton, from 5.4 to 8.73 cts. per bushel ; oats from $15.90 to $18.30 per acre and 

 from 24.7 to 33 cts. per bushel. 



Fertilizer tests at the central farm in a rotation of mangels, oats, clover hay, 

 and timothy have shown a distinct advantage of barnyard manure alone over 

 commercial fertilizer on this soil, but point to the possibility of combining the two 

 to good advantage if the manure is scarce or high in price. Fertilizer tests with 

 oats, potatoes, and turnips, and variety tests with oats, turnips, sugar beets, 

 and carrots, are also reported. 



Report of the Bavarian Cereal Breeding Station in Weihenstephan, 

 1912-13, L. KiESSLiNG (Landiv. Jahrb. Bayern, 4 {1914), ^'O. 6, pp. 576-633). — 

 This summarizes work in breeding and variety testing of cereals for 1912 and 

 1913. 



Besuits of variety tests of wheat, oats, and rye, G. M. Gabren {North 

 Carolina Sta. Bui. 232 {1915), pp. 3-28).— The results given in this bulletin 

 include tests made at the Buncombe, Iredell, Blantyre, and central station 

 farms, covering periods ranging from 1 to 10 years and presented in tabular 

 form. It is noted that with wheat practically all of the evidence of these experi- 

 ments is in favor of the smooth varieties outyielding the bearded, and that 

 home-grown seed also outyielded that imported from outside the immediate 

 vicinity. 



"Abruzzi rye has been found to far excel the common rye in yield of both 

 grain and straw. It is also ten days to two weeks earlier. It is especially 

 recommended for those who wish to sow rye for late fall or early spring pasture, 

 or for winter cover crop. 



" There has been found, upon the whole, about 50 per cent difference between 

 October sown and December sown wheat on the Iredell test farm. In every 

 instance there is a progressive decrease in yield from the sowing on October 10 

 to that on December 21. This is based on two years' tests and the results will 

 doubtless not be changed by future experiments. Wheat in the vicinity of the 

 Iredell test farm should be sown as early in October as danger from the 

 Hessian fly will permit." 



Storing the grain crop, J. F. Hoffmann {Landtv. Hefte, No. 28 {1915), pp. 

 40, figs. 10). — A treatise on methods for the artificial drying of grains, with 

 illustrations of various types of dryers. 



Zellers' hay and coal table {Hooper, Nehr.: The Zellers Publishing Co., 

 1915, pp. 51). — This is a table giving the values of pounds and tons up to two 

 tons with prices ranging from $2 to $14.25 per ton. 



Stacks, E. Rabat6 {Vie Agr. et Rurale, 5 {1915), No. IS, pp. 229-234, figs. 6).— 

 This article gives the results of a study of the site, form, dimensions, construc- 

 tion, cover, and cubature of stacks. Mathematical formulas and diagrams are 

 used to calculate scientifically the true proportions and cubature of different 

 forms of stacks of hay and cereals. 



Selection of yellow alfalfa at the Krasnokutsk Experimental Station, P. N. 

 KoNSTANTiNOV {Selsk. Khoz. i Lfesov., 246 {1914), Oct., pp. 173-191).— Thifi 

 gives the results of selection and hybridization work with Medicago falcata in 

 an effort to secure a plant sufficiently hardy to withstand the soil and climatic 

 conditions of southeastern European Russia and sufficiently prolific to become a 

 valuable forage crop.
