2 The difference between total volumes in this table and table 10 is accounted for by volume in nonsaw-timber types. Since average volume per 

 acre values are rounded off to nearest 100 board feet, the sum of unit total volumes computed by applying volume per acre to area will not exactly equal 

 regional totals.
