 various crops fnr different sections of tlie country. 



An experiment on the improvement of cereals, iv (isviiiKi {('liron. A(/r. 

 Cavton Vdwl, 14 {I'lOl), \<>. M, pj). .'/US-oOJ). — This article reports tlie resuHs (.f vari- 

 ety tests with oats, anil calls attention to the very promising results obtaine<l with a 

 number of foreij^n varieties, including American Banner and Improved American. 



The seeding of grain, .I.Si>i:ik {Join: Bd. A(p: [Lornlon], Jf { 1901), Xo. .f, jip. 

 438-441')- — This article discusses tillerinir, size of seeds, (luantity, germination, and 

 change of seed, quality of the land, date of sowing, l)road casting, and drilling, and 

 the los.ses which occiu' in seeding. 



Manures for a four-year rotation, D. A. (tilchkist (Jour. lid. Aijr. [Li>ihIi»i], 8 

 {1901), No. 3, pp. 324-3-^7). — An account is given of a four-year rotation and the use 

 of fertilizers in connection with it. The fertilizers were applied at the iK'ginning of 

 the rotation. The best financial results for the entire rotation were olitaineil fmni an 

 apj)lication of 2 cwt. of nitrate of soda, and fi cwt. of basic slag per a<'re. 



Experiments -with potash fertilizers, ('l.\isen {Ltnuhr. WHuihl. Srlilixirhj- 

 Ilohte'm, 51 {1901), Xo. .'f8, pp. 73G-739, jUj. 1). — In these exj)eriments oats, beets, 

 and horse beans were grown in pots containing a heavy marsh soil. Potash was sup- 

 plied to each crop in the form of kainit, 40 per cent jtotash salt, and sulphate of pot- 

 ash. The use of kainit gave the largest increase in the yield of oats, ami the applica- 

 tion of potash in general increased the |)roduction of grain as compare<l with that of 

 straw. The different forms ttf potash increased the yield of beets from 12 to 22 per 

 cent. Beets were found to be the most sensitive to impurities contained in tiie pot- 

 ash fertilizers. The results with horse beans were vitiated to some extent. 



Catch and cover crops, J . Gould ( Riiral New Yorker, 60 { 1901 ) , No. 2099, p. (191 ). — 

 An article discussing the culture of oats and Canada peas and of rape as catch and 

 cover crops. 



Fertilizer experiments on irrigated meadows, B. Tacke {}fitf. Dcut. Liindir. 

 de.^ell., li: {1901), No. 46, pp. JH.1,M4). — A description of the work and tlie results 

 obtained are given, and a grass-seed mixture for this class of meadows recommended. 

 It is the intention to continue the experiments for a series of years before drawing 

 definite conclusions. 



Itlanuring of meadow hay, K. S. Seton ( YorksJiirr Col., Leed>^, fnul IJa.st and West 

 R'liHiKjK .Taint Ayr. ConncU, Pmnphlet 14, 1900, ])p. 12). — The results of the coojierative 

 fertilizer tests on meadows conducted in 1900 rhowed that the most profitable pro- 

 portions of commercial fertilizers were IJ cwt. ot nitrate of soda, 2 cwt. sujierphos- 

 phate, and 8 cwt. oi kainit per acre. The annual or biennial use of Itarnyard manure 

 for this purpose was also found profitable. 



Rotation of crops as a means of destroying weeds on meadow^s, ri.uiCH 

 {Siu'lis. Liindir. Zl.^rhr., 49 {1901), No. 4.J, pp. 107. i, 1073).~\ brief account is given 

 of the ways in which a rotation may be arranged with a view to destroying weeds on 

 meadows.

 [London], 8 {1901), No. 3, ]>ji. 313-3:^3). — This article discusses the value derived 

 from the culture of deep-rooting i>lants, and dwells upon the necessity of conserving 

 lunnus and restoring it to the soil.

 {1901), No. 21, pp. 882-884, Jiy>^- 7). — This article discusses the growing of seed corn 

 and enumerates the varieties of corn bred in Illinois. The occurrence of barren 

 stalks is also liriefly considered. 



Corn crop tables of Standard Cattle Co., Ames, Nebr. {Auwk, Nehr.: SUunUtrd 

 (Juttle Co., 1900, pp. 16). — These tables show the yields of corn, the estimated 

 amounts of stover, and the cost of producing the crop on the lands of the company 

 for the vears 1893-189*», inclusive.
