cernin<r tin- value of the harley. In a later communication Jalowetz 

 recommend- that tin- protein content of the individual irrains he taken 

 into consideration in-tead of the percentage of protein. 

 A irood harley -hould he -ound. have a high germinating power, 



he rich in -larch, and. according t<> the Kuropean -v-lem of valua- 

 tion, low in protein. That the lir-t requisite for ir'>d harlev is life, 

 high genninatinir power, and uniform germination need- no dis- 

 cii ion, and the-e may he-t he ..htained hy the production of pure

 and at harve-t. the fert ili/ei-- ii-ed. anl the rotation of crop- prac- 

 ticed, etc.. may aid in e-timatinir the value of harley. l-'or example, 

 it i> well known that a late rain di-color- the irrain and make- it leflB

Although all the factor- enumerated in hoth -\Mem- are im- 

 portant to a greater or !-- extent, from a lnv\\-r'- \ie\v point, yet. 

 for the priNluctioii of alcohol in the agricultural and industrial dis- 

 tillery, -ome of them may well he riven a -econdai'v po-ition. Such 

 factor- a- tinene of hu-k-. mealine-- of endo-perm. -hape of irrain, 

 impurity, and color are of le-- importance in alcohol production than 

 in the hreNxinir indii-try. though even ihe-e factor- are of help in 

 valuing a distiller'- harlev. Recently harvested harleys have a 

 low nrerminatin^ power, therefore they should not he malted until 

 at lea-t three month- old. The dia-tatic power of malt is the chief 

 factor when u-ed for alcohol production. This factor i- more or 

 le influenced hy the characteristic- of the ^rain : namely, uniformity 

 a- regards race and a ire of harley. weight per l.(H)0 nrrains. and pro- 

 tein content. A <rood distiller's harley -hould have the following 

 characteri-tic-: IIirh ir^nninatinir power. hi<rh protein, uniformity, 

 good color and odor, and cleanness. The malt produced therefrom 

 should possess a hijrh diastatic power, have a plea-ant odor, a sweet 

 and airreeahle ta-te. and he free from dirt. A- a harley rich in nitro- 

 gen i- generally one which will yield a malt of high enzymic pow r er
