The samples “X” and “W” represent fair samples of tobacco from 
the same plants, cured as follows: Thirty plants, which had an even 
number of leaves, were selected from the field, the alternate leaves 
stripped off from each plant, and strung on wire. The number of 
leaves on the wire was 129, and the same number were left on the 
stalk. Both the plants containing the remaining leaves and the 
leaves on the wires were then hung side by side in the Snow barn 
and cured with other tobacco. The samples by both processes were 
taken down, the leaves stripped from the stalk, and the leaves from 
both methods were weighed with these results: 
Leaf-curing process.. 62 J oz. 
Stalk-curing process. 58^ oz. 
Excess over stalk process....... 4 oz. 
This experiment was suggested by the claim of the Snow Barn 
Co., that leaves cured by their process would weigh more than when 
cured on the stalk. It is true that the leaves cured on wire weighed 
a very little more in this case, but as there was so small a quantity 
of leaves tested, and only one trial, it is not safe to draw conclusions. 
The small variation might possibly have resulted from an excess
