180 RECAPITULATION. 
working systematically in an organized forest with good roads, standards 
could be planted and cared for till their heads were definitely beyond 
the danger of being dominated, at a cost per acre ranging UP to £3. 
In such operations ‘‘ well-timbered acres ’’ in the forest of to-day would 
far more than pay for ‘‘bad acres.’’ The balance would be struck 
yearly: there would be no interest charge on the cost of putting the 
forest in order. ‘That has been the general scheme of forest improve- 
ment in the cultivated forests of Europe. 
Apart from a few specially reserved Government Kauri forests, two 
or three years will see the end of the Kauri timber, but that happily is 
not the end of the Kauri forests. Some areas show quite a satisfactory 
natural regeneration in spite of partial further fires and grazing—in- 
deed, light grazing may be beneficial to Kauri natural regeneration. 
Larger areas are restorable at moderate expenditure. Land of this sort 
on the western side of Waipoua, extending nearly to the sea, has been 
included in the demarcated area. Many of the present patches of mull- 
able Kauri one sees to-day are clearly’ regrowth forest after former 
forest-fires. 
It is estimated on good authority, and that estimate is supported 
by a study of the coloured ‘‘ Land Tenure ’’ map of 1916, that quite half 
a million acres of Kauri forest might still be saved with a policy of 
liberal demarcation and redemption, the Kauri-timber crops from such 
area being calculated as sufficient eventually to fully pay all possible 
charges on the war debt—viz., 500,000 acres, with a yearly net revenue 
of £10 per acre, would yield the State £5,000,000 yearly. The bulk 
of this half-million acres would be in the Coromandel Peninsula and 
Hokianga. 
THe Kavurt Forest or THE FUTURE. 
These calculations depend on the yield to be expected from the culti- 
vated forest of the future. With a study of the growth of Kauri and 
other timbers in the present forests of New Zealand, and a knowledge 
of forest similar to it in India, East Africa, and South Africa, and 
using the yield-tables of long-cultivated forests in Europe, approximate 
figures for the normal Kauri forest of the future in New Zealand can 
be worked out. These may be expressed in general terms thus :— 
Normal Kauri Forest. 
Average age of the main timber crop a 100 years. 
Average number of trees per acre in the first main 
timber crop (about)... Za 100 trees, 
Average cubic content of each tree (boles only). ... 100cub. ft. q-¢. 
Acrim (= average production of timber per acre per year) 100 cub. ft. q.g. 
These figures are smoothed to represent general averages. It is re- 
markable that they should all come out so near the figure 100.* 
Something like this would be the normal forest to be kept in view 
during the next 100 years. Thence onward it would be gradually 
improved, the number of Kauri or other first-class trees doubled or 
* These figures may be conveniently memorized in the following tag :— 
When the forests of Kauri get their ten-guinea stocking 
The old-time destruction will seem rather shocking. 
One hundred years, one hundred trees of one hundred cube q.z., 
Will give one hundred “acrim ”’ in a two-feet sixty tree, 
The tree here referred to is 2 ft. in diameter at breast-high, and has a bole of 60 ft.
