 to the burning Qualities of Tobacco. (Bull. Bur. Plant Ind. U. S. 

 Dept. Agric. Washington. 1907. 105. p. 1—27.) [The fire-holding 

 properties of tobacco are dependent on the presence of potassium 

 combined with organic acids chiefly citric and malic. Chlorine 

 and sulphuric acid combined with potassium injure the fire-holding 

 qualities of tobacco. Lime has little effect on burning qualities 

 but makes good ash. Magnesia harms fire-holding capacity. —
