 REGULAR 4-INCH SIZES 



The scries of standard 4-inch sizes i> Illustrated 



by the chart shown in Figure 4. Each size of this 

 series has a fixed variation of 1 Inches (or 10 cen- 

 timeters) in length, and breaks on multiples of this 

 variation. 



REQUIREMENTS 



When tobacco is represented to be of any one of 

 the standard sizes covered by the chart shown in 

 Figure 4, 75 per cent of the leaves of the lot or 

 package must fall within the range of such size. 

 For example : If a lot or package of tobacco is repre- 

 sented to be of U. S. size 44, then 75 per cent of the 

 leaves of such lot or package must be between 16 and 

 20 inches (or 40 and 50 centimeters) in leogth. 



APPLICATION 



The sizes of the regular 4-inch series are used to 

 state the length factor of grades in which the length 

 of leaf is not of such great importance. The varia- 

 tion of these sizes is sufficiently close for all grades 

 of certain types and many grades of other types. 

 These sizes are particularly applicable to the flue- 

 cured and air-cured types, and are used to some ex- 

 tent in the fire-cured, as well as in most of the cigar 

 leaf types.
