 Geuenil comincDt, iiicliiding a brief <lescription of nietbods pnr.sued by tbe Longer- 

 enoTig Agiicultural College, Australia.

 {Staz. Sper. J (jr. Ital., 28 {1895), No. l,pp. GS-7-i). 



Practical experience concerning the effect of stable manure in the light of 

 recent investigations, P. Wagner {Dent, landw. Presse, 22 {1895), No. 14, p. 123). 



The nitrogenous fertilizers of commerce, C. Dusskhke {Chron. Agr., 8 {1895), 

 No. 5, pp. 102-105). — Brief general statements. 



A study of the agricultural value of the phosphate of alumina of Grand- 

 Conn6table, A. Andouard {Compt. Mend., 120 {1895), No. 6, pp. 357-339). — This phos- 

 phate Avas compared with other mineral phosphates, including Algeriiiii, Somiue, 

 South Carolina, and Florida phosphates in pot experiments on balsam, iiax, white 

 mustard, and buckwheat, with results indicating that it may be profitably used in 

 untreated condition. More complete Held experiments are stated to be in progress. 



On the agricultural value of the phosphates of alumina— remarks on the 

 previous note, A. Gautihr {Comptt. Rend., 120 {1895), No. 7, pp. 356-358). — Recoimts 3 

 years' field experiments on a large scale with Redouda and Connotable (Guana) 

 phosphates, which confirm Andouard's conclusions as to the high assimilability of 

 such phos]ihates, but it is maintained that this high assimilability is confined to 

 those phosphates indirectly resulting from fermentation of nitrogenous matter, and. 

 generally in an ajnorphous or indistinctly or partially crystallized condition. 



Preparation of a fertilizing material containing citrate-soluble phosphoric 

 acid, O. Peiper {Chem. Ztg., 19 {1895), No. 11, p. 221). — A patented jirocess in which 

 fine ground iron or aluminium phosphate is stirred into a hot solution of lime in 

 soda or potash. 



Fertilizers and gypsum {California Sfa. Fpt. 1893 and 1894, pp. 2SJ-50C).— Analyses 

 of 3 samples of fertilizers and 37 samples of gypsum or gypseous earths, with accounts 

 of gypsum mines located near Mendota, Fresno County, and in San Benito County, 

 California.

 barnyard manure, J. KiiHN {Zlscltr. landiv. Cent. Ver. Sacliset), 1895, No. 1, pp. 4-12). 



Manure in its relations to plant evaporation, C. D. Eeed {Amer. Ayr., {middle 

 ed.), 1895, Feb. 23, p. 194). 



Analyses of commercial fertilizers, T. J. Edge and W. Frear {Pennsylvania 

 State Bd. Agr. Dul., Jan. 1, 1895, p)p- 24). — Text of the act regulating the manufac- 

 ture and sale of commercial fertilizers in Pennsylvania; schedule of trade value of 

 fertilizing ingredients, with notes on valuation; and tabulated analyses and valua- 

 tions of 312 samples of fertilizing materials, including ground bone, acid phosphate, 

 and mixed fertilizers. 



FIELD CROPS. 



Experiments with corn, S. M. Tracy {Mississippi Sta. Rpt. 1893, 

 pp. 18-23). — These consisted of variety tests and fertilizer experiments. 

 The largest yields in 1889 were made by Mosby Prolific, St. Charles 

 Parish, White Dent, Improved Learning, Welborn Conscience, and 

 Piasa King; in 1890 by Mosby Prolific, Cock Prolific, Minter Prolific, 

 Bailey, Mammoth Surprise, and Evans. In 1889, 1890, and 1892 the 

 white varieties yielded more than the yellow varieties. 



"As a rule the yellow varieties make larger ears, but Ave have found very few 

 which average more than 1 ear to the stalk. Of those varieties noted as being the 

 best 6, tile white varieties averaged 127 ears to 100 stalks, while the yellow varieties 

 bore only 105 ears to 100 stacks. ... It is probably true that the yellow varieties 

 stand up better in the field and are less liable to rot when left in the field until late 

 in the season,"
