     1   Q.   That is three of 60 each; the first thinning being the one
     2        row in three or the two in five of pretty small trees?
     3        A.  Correct.
     4
     5   Q.   And the subsequent ones being individual but larger trees?
     6        A.  Correct.
     7
     8   Q.   At the end of the day you cut down what is serviceable
     9        which is left of mature trees and that gives you 300
    10        metres?
    11        A.  That is correct, my Lord.
    12
    13   Q.   That is on one hectare over 40 years, so to get the annual
    14        equivalent you would have to use 40 hectares?
    15        A.  Correct.
    16
    17   Q.   That may not be what actually happens but it is a way of
    18        doing the arithmetic?
    19        A.  It is a calculation.
    20
    Q.   An annual calculation of some kind?
    22        A.  Yes.
    23
    24   Q.   That is the full extent of that calculation?
    25        A.  That is the meaning of that calculation.
    26
    27   Q.   Then if you want, therefore, to carry on the calculation,
    28        you can divide it again by 40 to get 12 metre cubed per
    29        annum per hectare?
    30        A.  Yes, this is the way by which they calculate the
    31        potential yield from a forest by yield classes, and the 12
    32        metre cubed per year is the method by which they actually
    33        identified that this is a yield class 12 area of forest
    34        which is a very normal production of volume.
    35
    36   Q.   You are not saying that if you selected and marked out one
    37        hectare you would actually be taking 12 cubic metres of
    38        timber off that hectare every year?
    39        A.  No.
    40
    Q.   You are not saying that if you marked out a section of
    42        forest which was 40 hectares an area you would be taking
    43        off 480 cubic metres each year because that is just not the
    44        way the forestry is done?
    45        A.  That is correct.
    46
    47   Q.   So you do this ---
    48        A.  Over the cycle.
    49
    50   Q.   -- correct mathematics, as it were, to give you an 
    51        impression of what you are getting off areas of forest 
    52        cycle -- by cycle, over a long period of time; is that 
    53        right?
    54        A.  Yes, my Lord.  That is actually why on the bottom of
    55        that page he sets it out, showing that there is a yield
    56        growth factor, in other words, your thinnings increase in
    57        volume and your final clear fell produces in the end the
    58        total volume that you anticipated.
    59
    60   Q.   The 48 metre cubed left in the forest, what is that?
