Mustard and turnips as catch crops, P. (Iknay (Scmatnc Agr., 21 (JOOl), No. 

 J0.')3, }>]>. '22S-J'yO). — In connectidu witli a <j:t'iifral discussion of tlu' subject analyses 

 of both plants are reported. 



Alfalfa on muck, W. K. Imes [Ann'r. Gard., 22 (1901), No. 351, p. e.?,5).— The 

 author reports trrowinfj 8 tons of dry alfalfa hay i)er acre on muck land in IMichigan. 



Soil inoculation for alfalfa, G. C. Watson and K. II. Hess {Pniiii^iilmnia Sta. 

 l\])l. 1900, i>p. S07, 30S). — Inoculation tests for alfalfa with Nitraj^in and with soil from 

 an alfalfa field are reported. The best results were obtained on the plat treated with 

 soil from alfalfa ground. The use of Nitragin also showed some effe(!t. The yields 

 in general indicated that alfalfa is not w'ell adapted to shallow limestone soils. 



The influence of potash salts on the development of barley, J. Stoklasa and 

 J. PiTKA {/.Isrhr. Laiubr. W'r.'iuchsir. OeMerr., 4 {1901), No. 5, pp. 567-582, fig. 1).— 

 The work hi're ivported consisted of pot experiments made to determine the influence 

 of potassium chlorid as a fertilizer on the qualities of brewing barley. The pots 

 were divided into Ti groups of 10 ]iots each, according to the (jnantities of potassium 

 chlorid aj>]>lied. Each pot received 0.5 gm. of nitrate of soda and 1 gm. superphos- 

 phate furnishing 0.101 gm. of phosphoric acid, while the quantity of potassium 

 chlorid per pot varied from 0.5 gm. to 3 gm. The results of the experiments are 

 summed up in the following table:

These results show that a rational application of muriate of potash in conjunction 

 with superphosphate and nitrate of soda was beneficial to the development of the 

 barley plant and the improvement in quality of the grain. 



Thick vs. thin seeding of corn {Nev. Jcrseg Stm. Rpt. 1900, pp. 265, 266).— South- 

 ern White corn was })lanted June 8, the kernels being placed 10, 12, 14, and 16 in. 

 apart in the drill on 4 different plats. The seed required per acre at these different 

 rates of planting was 6, 5, 4, and 3 qt., respectively. The largest yield was obtained 

 where the kernels were planted 10 in. apart and 6 qt. of corn were used per acre. 

 This plat yielded 9.03 tons of silage c(jrn, or 20.7 per cent more than the plat with 

 the thinnest planting. The plat with the thickest planting suffered most from dry 

 weather and j^roduced the smallest ears, but still results indicate that the thickest 

 planting was the most profitable for silage corn. 



Cotton, E. Grimlev {Que<-ii.'<land Agr. Jour., 9 {1901), No. 1, pp. 118-121, figs. 

 2). — \ i)aper on cotton culture in Queensland, treating the subjec-t largely from a 

 financial standpoint and discussing the conditions tmder which it may be profitably 

 grown. 



Cotton in Egypt, Y. IIexrv {Agr. Prat. Pays Chauds, 1 {1901), No. 1, pp. 55- 

 88,fig.'<. 2). — This article describes a mnnber of cultivated varieties of cotton, discusses 

 the climate and soil of Egypt, and gives concise descriptions (.<f the methods of grow- 

 ing, ginning, and ])aling cotton in that country. Chemical and |)hysical analyses of 

 the soil and an analyses or Nile water are rei)ortcd. 



Comparative tests of red clover from different countries, U. IkRciiAKD 

 {Landir. Wrlmhl. Srlil,i<irig-nnht(''ni,51 [1901], No. :U ,/)]>. 450-454). — Froiu the results 

 obtained it is concluded that red clover from North ,\merican sources is better a])le 

 to stand severe winters than red clover obtained from Southern and Western Europe.
