 "Crumple" is, I think, the word that covers their

The 24 species were represented by 229 trees, carry- 

 ing a volume of 33,158 cubic feet, which works out 



at 829 cubic feet per acre, and 145 cubic feet per tree, 



and 5.7 trees to the acre. Of all the species, No. 376 



— hoop pine (Araacaria Cunninghamii, Ait.) — was the 



most plentiful. It was represented by 52 trees, or 22.7 



per cent, of the stocking, and 9,131 cubic feet, or 27.5 



per cent, of the volume. The volume per tree works 



out at 175 cubic feet and 228 cubic feet per acre. 



Next to the hoop pines come the two oaks, No. 418 and 



425. They account for 41 trees, 4,680 cubic feet or 



117 cubic feet per acre, and 114 cubic feet per tree; 



13 per cent, of the volume, and 18 per cent, of the 



Next in volume, we come to No. 384, a 



species ~of Eugenia, which is represented by only 3.3 



per cent, of the stocking, but by a volume of 3,804 



cubic feet, which works out at 11.5 per cent, of the not be seasonal. The timber is lighter than Podocarpus 



total volume. This is sere, a large tree which is most nerifolius. 



Next in order is N"o. 389 — Ibai — a Crvptocaria not 

 as yet specifically determined. It is a large tree yield- 

 ing a mill log of 70 feet, with a girth at butt of 8 feet. 

 Its timber is mouse grey, but has a pleasant quarter 



and would make a good all round wood for 

 decorative 1 panelling and indoor work. It is not too 

 heavy for furniture. It is represented by 15 trees or

lades. They are really flattened, widened shoots, but 

 pass as leaves to the ordinary person. They have a 

 pretty powder blue bloom beneath, and this is much 

 more marked in the young seedlings than in the 

 "leaves" of old trees, as is the size, which is sometimes 

 twice that of mature philloclades. This is a species 

 that is not found at the lower limits of the belt, and 

 really only reaches its best dimensions at 7,500 feet. 

 It persists up to 9,000 feet, but rarely exceeds 5£ feet 

 in girth and 25 feet high at the latter elevation. It 

 is, at its best, a very short, stout boled tree— 30 f(>e+ 

 of bole would be about the average, and the girth runs 

 up to 16 feet. Overall it does not exceed 50 feet. It 

 has a thick, ridged bark, which is so dark a brown 

 as to be almost black. It yields a compact pine wood 

 with well marked concentric rings, which may or may 



between 7,000 and 



8,000 feet on a flat- 



conspicuous , 



tish ridge where most of the broad-leafed specie- 

 occur. The bark is light brown and very scaley, and 

 persists in an untidy manner. It yields a very hard, 

 close-grained, heavy timber of high value for con- 

 structional purposes. N T ext in order is No. 3< j, which 

 accounts for about 6 per cent, of the stocking and

 timber is fine, close-grained yellow wood. Seasonal
