TOBACCO CULTURE IN THE WEST INDIES 35 
TOBACCO ANALYSIS 
Prof. Wagner obtained 19 samples of tobacco from the 
United Laukat Plantation Company in London and found 
the following plant food and chlorine content: 6.09% pot- 
ash, 0.489% phosphoric acid, 3.48% nitrogen and 0.553% 
chlorine. Seventeen samples of Sumatra tobacco obtained 
from Laeser & Wolf, Tobacco dealers in Bremen, contained 
6.855% potash and 0.751% chlorine. These seventeen 
samples, ranging in price from $25.50 to $136.00 per 100 
pounds, were tested for burning quality and one sample 
valued at $136.00 and containing 7.173 % potash and 
0.294% chlorine, had a burning duration of 128 seconds 
while another sample valued at $42.50 and containing 
7.233% potash and 1.170 chlorine burned 116 seconds 
only. Showig that the high chlorine content in the latter 
sample lowered the burning quality and consequently the 
price. 
Of the two other samples taken at random from the same 
lot, one valued at $25.50 and containing 5.26% potash and 
1.735 % chlorine, burned 32 seconds only, while another 
valued at $123.50 and containing 8.221% potash and 
0.859 % chlorine burned 345 second. 
The foregoing diagram shows the burning duration of 
fermented and cured tobaccos with varying potash and 
chlorine content. 
Of Cuban tobacco, Prof Wagner reports four samples
