White-rumped Wood-Swallow (Artamus leucorhynehus), 
Wliite-Throated Tree-Creeper (CTimacteris lencopliaea), 
and Golden-breasted Whistler (Pacliycephala pectoralis). 
With regard to the latter bird, it -was remarkable that 
no males were seen, though birds in female plumage were 
fairly frequent. In at least one instance the bird had 
a considerable amount of yellowish colour beneath tlie 
base of the tail, a characteristic of the females of this 
species, which T have previously noted on Stradbroke 
Island, but not on the mainland adjacent. Other birds 
seen in this country were the Crow (Corvus cecilae), 
Collared Batehei'-bird (Cractieus torquatus), Black- 
faced Cuchooshrike or Blue- Jay (Graucalus novaehol- 
landiae), Bar-shouldered Dove (Geopelia humeralis), 
Mistletoe-bird (Dicaeum hirundinaceum) and Red-brow- 
ed Finch or Red-head (Aegintha temporalis). At night 
a Boobook Owl (Ninox boobook) was heard calling, and 
one afternoon a Wedge-tailed Eagle or Eaglehawk 
(Uroaetus audax) was seen soaring high over the hills 
and trees.

VERTICAL GROWTH OF TREES. 
Mr. Conrad C. Dornbusch, of Warwick, writes: — 
^‘From time to time there have appeared in the news- 
papers discussions as to whether the limbs of trees grow 
upward as the tree increases in height. I send you here- 
with two photographs of the same tree, taken from ap- 
proximately the same view point, but with an interval of 
12 years. 
The tree in question is a cabbage gum (Angophora 
laneeolata) growing on the line of a fence. The fence 
rails were housed into the trunk some years before 1913, 
and the bark grew round the ends of the rails for some 
little distance on each side. A comparison of the two 
photographs wdll show that the ends of the rails are 
practically in the same horizontal position now as they 
■were in the year 1913, and I should regard this as good 
evidence that the lateral limbs of a tree are not carried 
up wdth the growth of the tree. 
(The point raised by Mr. Dornbusch has often been 
discussed, and there are several references in Australian 
literature to the effect that tlie bole of a tree below' the
