96 RALANGE-SHEBT OF A NORMAL KAURI FOREST. 
First Prrrop.—THE WORKING OF THE Vircin Forest. 
Revenue.—The quantity of timber, and the time taken to work it, 
will depend on the forest and circumstances of working. For the 
Waipoua Forest, for instance, the working may take 20 years. The 
timber there ig valued at an ayerage of £18 17s. 10d.* per acre, and the 
Kauri ‘‘gum’’ may be worth 10s. per acre more. t ce 
EBxpendituret.—No general figure can be given for this either, since 
it depends (1) on the present ‘‘stand’’ of timber, which varies from 
acre to acre and from forest to forest; (2) on the development that has 
taken place, and consequently transportation facilities, This should be 
very good at Waipoua. It was poor when the best of the Puhipuhi Was 
destroyed, very good afterwards. The outstanding feature of the Puhi- 
puhi loss is not only that the forest was worked recklessly, but worked 
too soon. As a general figure of logging-costs, the secretary of the 
Kauri Timber Company (Timber Commission, 1909, p. 565) quoted 
4s, 5d. per 100 sup. ft. The average in America, U.S.A. (Moon and 
Brown), is half this.

An Average Acre of Normal Kauri Forest. 
Revenue.—The forest is now growing up largely regularized with a 
certain number of Kauri standards (young trees) left over for mid- 
rotation fellings, and such thinnings generally as may be required.

Kauri ‘“‘gum,’’ fungus, &e.: There will be no old 
trees, but the heavy tapping before felling of the 
Kauri reserves will yield a fair supply of ‘‘ gum”

* This is at pre-war prices, and very rough estimates of the timber. 
T The yield of Kauri “gum” estimated must necessarily vary within wide limits, 
since so little is known about the systematic tapping of Kauri for “ gum.”” I see no 
reason why, at least, the amounts estimated here should not be realized. For a forest 
that is at all accessible the value of firewood will at once make this estimate far too low. 
t The cost of special regeneration measures (p, 116) is not set down here. Tt may 
amount to £2 or £3 per acre, and is paid for out of fellings: or it may be looked on 
as balanced by the cost of grassing if the forest were to ‘be destroved and taken for 
Rees tp. parts of the forest, gum-digging (of course, under strict control) will not 
mn Ff thate Aah ane ground ready for planting, but also pay the cost of the young trees 
§ This figure may seem high, but it includes such timbers as Totara, Rimu, Celery- 
top (Tanekaha), and Puriri, some of which, where favourably situated, have already 
touched this figure; and allowance has here to be made for the better growth and 
accessibility of the cultivated forest. This may be the maximum average price these 
timbers will reach, though Totara and the best of them mav get near Kauri prices.
