Mpply tlio ni.mnro in the f:ill in order that the chlorln may loach ont dnring 

 thi> '.vintrr. Attcnticm is called to the fact that stock fed with heet leaves 

 prod ice a niannre hiuh in chlorin, while feedinj? molasses or hay heavily 

 fertilized with |potash prodnces a manure rich in potash, so (hat in a measure 

 the chlorin and |iotash content of barnyard manure may be controlled. 



A comparison between sulphate of potash and silicate of potash, or martellin, 

 showed 4.4 per cent of i)otash, 1^.2 per cent of chlorin, and a lire-holding capacity 

 of 4 seconds in the leaf si'<»wn with sulphate of i)otasli, and (5.0 per cent of 

 potash, 1.2 i>er cent of chlorin, with a tii'e-holdini;; cajpacity of (j() seconds for 

 the tobacco grown with the martellin. 



The use of annnonium sulphate produced in all cases a greater lire-holding 

 capacity than annnonium nitrate, the average results in .'! ditCei-ent tests being 

 41 and 34 seconds, respectively. 



The nature of tobacco fermentation, H. .Tknsen (Crnthl. Halt, [etc.], ,?. Aht.. 

 21 ilHOS). .\(,. I.')~ni, 1)1). .'itiit-.',.Sj, (l(/iii.s. J I). — The results reported show that 

 t<»bacco fermentation is not prevented by treating the leaf with corrosive subli- 

 mate, formol, or chloroform, and that fermentation is itromoted by weighting 

 down the mass and by fermenting in large bulks. Fermentation was found 

 impossible in small quantities of t(»bacco, even though air was forced through 

 them or they were inoculated with fermenting leaf. The effects of fermentation 

 either in part or in their entirety were brought about by heating with steam 

 from 1(» minutes to 2 hours at a temjierature from 90 to 100° f\ Wet tobacco 

 was brought to an active state of fermentation even when tli(> bulk was small. 

 Fermentation was impossible in tobacco which had been treated with steam as 

 well as in leaf which had already gone through the process. Forcing oxygen 

 ilnough (he tobacco to be fermented did not jiromote fermentation.

Observations on the breeding' of Vicia faba, II. Lang {Fiihliug's Lnndw. 

 Zti/., 57 (I'tOH), \o. //,. pp. ,{,s/-/,.07).— The results of this work show that the 

 most efficient factors on which selection in breeding ma.v be based are the num- 

 ber of pods per plant, the length of the plant, and the size and light color of the 

 seed. Selection according to the i)ercentage of seed and the number of beans 

 per pod j»roduced remained without detinite results. The weight of (ho beans 

 Iter pod seemed quite constant and reliable, but the use of this factor is con- 

 sidere<l impracticable. It was further observed that progeny high in plant 

 weight and yield of beans also ranked high in other imi)ortant characters such 

 as size and color of grain.'number of pods per plant, yield of beans per pod. and 

 leiigtli of plant. 



Report on a test of varieties of wheat with notes on the weather at Gar- 

 forth, 1907, U. S. Si;to.\ (IHir. Leeds <i)id Yorhsliire Council .[(/r. Ed. \l'iiin- 

 l'lilri\ liU, nxn, pp. /.?). — The results of variety tests here reportinl indicate that 

 Stjindard Ked and Squarehead .Master proved to l»e the best red wheats. I?ro- 

 wick (Jrey ChalT, although a good yielding variety, was not so good in qmility 

 as these two. but on account of its greater strength of straw it is better adapted 

 for land In good condKion than either. White Standup, the only white wheat 

 grown, was not so rennmcrative as (he best red wlH>ats. aKhongh cliai-acterized 

 by stiff s(raw of medium lengih an<l well adM|)ted to land of good ipialily. 

 iMilnth wheat jilso gave promising results. Scpuirehe.id M.isler. now grown
