A series of pictures followed, showing a Motu girl undergoing 
the painful operation of tattooing ; the method of fishing with a 
torch and a hand-net from the Lakatoi canoes ; pottery making ; 
a spear fight at Hula; and native pig-hunting. 
During the short interval some native music—a love song, a 
war song, and a duet—were reproduced from gramophone records. 
Resuming, Mr. Dunning explained the types of houses built 
out in the sea, also those in treetops. 
The ladies were next given some domestic hints on cooking 
pork, which were not so favourably received as might have been 
expected from the lecturer’s glowing description. 
A series of original photos followed, of a boy making a fire 
with some wooden fire sticks ; of the native tobacco pipe and the 
ingenious dog ladders ; and string manufacturing and dressmaking. 
Some pictures of curious burial ceremonies, together with some very 
artistic and interesting views of Lakatoi canoes, brought the 
lecture to a conclusion.

Restocking of Flora and Fauna, 
BY 
Me. HENRY DAVEY: 

HE problem, said Mr. Davey, of preserving fauna and flora 
which man’s interference threatens with extinction, is much 
less simple than appears on the surface. The largest and most 
highly developed mammalia, such as the elephant, the bison, and 
the lion, are the species most in danger, and nothing but strict 
preservation can save them. ‘The more beautiful and local birds, 
the birds of paradise and the lyre-bird, require equally strict 
preservation. Whether preservation, however thorough and cem- 
plete, will be altogether successful is just a little questionable ; 
and I shall give reasons for showing that other factors besides 
man’s attacks may be involved. ‘The examples will be taken 
from butterflies, the only department of natural history with which 
I can claim to have some real acquaintance, and which happens 
to be specially fertile in suggestive facts. These established, I 
shall show briefly how they affect the question of restocking.
