sample of wrapper, and in each case the binder was taken from the 

 same leaf as the wrapper. In the first group (A), a sample of filler 

 grown in Texas from Cuban seed was used; in the second group (B), a 

 heavy filler grown in Ohio from domestic seed; in the third group (C), 

 a filler grown in South Carolina from Cuban seed; in the fourth group 

 (D), an imported Cuban filler. The wrapper used on these cigars was 

 a type of Sumatra tobacco grown in Connecticut and had a very good 

 burn. The Texas and imported Cuban fillers were known to have an 

 excellent burn, while the South Carolina filler was markedly inferior 

 in this respect and the Ohio filler intermediate in burning qualities. It 

 will be seen that this sample of wrapper burned quite evenly when 

 used with the imported Cu])an and Texas fillers, while with the Ohio 

 and especially the South Carolina tillers the burn was decidedly uneven. 

 On the other hand, the effect of using different types of wrapper on 

 the evenness of burn of an}' one type of filler was less marked (see PI. 

 IV, A, B, and C; also PI. Ill, D). The filler used in this experiment 

 was the imported Cuban, while the wrappers were taken from four dif- 

 ferent types of Sumatra tobacco grown in Connecticut. Of these four 

 types of wrappers, that shown in Plate III, group D, had the best burn 

 and the one shown in Plate IV, group C, the poorest, although little 

 difference could be seen between the two when smoked on the Cuban 

 filler. The use of different binders did not cause any marked differ- 

 ences in the evenness of the burn, as is shown in Plate IV, groups C 

 and D. The cigars used in this experiment were all made from the 

 same wrapper and the same filler, while in group D a sample of Con- 

 necticut Broadleaf tobacco was used as the binder, and in group C the 

 binder was taken from the same leaf as the wrapper. 



Another important factor in determining the evenness of the burn is 

 the proper balancing of the component parts of the cigar. It was 

 found, for example, that a very light" wrapper will not give good 

 results on a heavy filler, even though both of these may in themselves 

 possess a good burn. It will readily be seen that a very thin wrapper 

 which burns readily and very rapidly will, when placed on a heavy, 

 slow-burning filler, tend to burn in advance of the latter, and the effect 

 will generally be an uneven burn. The same result is obtained when 

 any cigar is smoked very rapidly, for the reason that the oxygen of 

 the air has freer access to the outer edges of the burning zone and 

 under the added stimulus it rarely happens that a cigar will burn 



evenly. 



As regards the character of the ash, the wrapper and the binder are 

 relatively of nmch more significance. It was found, it is true, that 

 some fillers give an ash lacking in compactness and liable to split 

 asunder, but the tendency to flake seems to be controlled almost entirely 



a The terms l(g]it and heavij as used in this connection refer to the body or thick- 

 ness of the leaf, which largely controls the rapidity of the burn.
