(1) Demands of the trade especially with reference ta- 

 burning qualities. 



(2) AVhat amount of chlorine is allowable and what 

 amount of potash essential to the desired burning quality. 



(3) Eftect of soil on the burning quality. 



(4) Amounts of chlorine and potash removed from the 

 soil by dift'erent crops and effect of previous cropping on 

 the burning quality of tobacco. 



(5) Amounts of potash and chlorine furnished the soil 

 in dift'erent manures. 



(6) Eftect of manuring on burning quality. 



(7) Eftect of previous cropping and manuring on the 

 properties of tobacco other than that of burning. 



(8) Injurious and beneftcial methods of cropping and 

 manuring tobacco. 



The various properties of the tobacco leaf, burning qual- 

 ities, size, weight, color and fermentive properties, are all 

 more or less aftected by the variety of tobacco, the soil, 

 time, and manner of manuring, climate and the time of 

 ripening. 



The properties of tobacco may also be aftected by the 

 manner of curing and the weather durint the curing. 

 The fact that so many factors play an important part in 

 determining the quality of tobacco makes this part of the 

 subject a difficult and tedious one to study and understand. 

 To secure the desired burning quality, the amount of 

 chlorine must not rise above a maximum, nor the amount 

 of potash sink below a minimum. From studies made of 

 forty-six samples of tobacco, grown in Baden, Germany, 

 on dift'erent soils and with dift'erent manures, the conclu- 

 sion was, that tobacco continued to glow longer, i. e.,. 

 burned better, the more potash and less chlorine (sodium 

 chlorine) it contained. 



In general, tobacco will be of inferior burning quality ,- 

 which contains more than 0.4 per cent, of chlorine, and 

 less than 3.5 per cent, potash.
