It will now be possible to calculate the possibility of each coupe. 
The Rein ties Boules forest should when normally constituted con- 
tain 63'5 trees per hectare, with diameter of 45 centimeters and 
over; or 2,352 trees for the whole area of 3T‘04 hectares. The enu- 
meration carried out in 1905 shows that there are actually 2,984 
trees. In other words, that there exists a surplus stock of 632 trees, 
which must be removed. But, in order to proceed with caution, it 
will be safest (bearing in mind that the figures of the normal forest 
are purely hypothetical) to spread the removal of this surplus stock 
over 40 years ; that is to say, during the first felling period of 10 
years only j of the available surplus stock will be removed. 
Accordingly, the possibility per coupe may be calculated as fol- 
lows : —
