246 JOURNAL OF SCIENCE. 
With reference to the controversy regarding the origin of these 
drawings, and the date of their execution, it is satisfactory to 
find such competent judges as Mr. Maskell and the gentlemen 
who accompanied him—after a careful examination of the 
drawings on the rocks—arriving at the conclusion that they 
were “undoubtedly older than European settlement here.” 
The Maori evidence removes them a stage further back, to a 
xeriod antecedent to the Ngai Tahu occupation of this island. 
How much older they may be remains a fair subject for specu- 
lation.—I am, &c., JAMES W. STACK.

NEW ZEALAND MOTHS. 
S1R,—My name is mentioned in No. 4, vol. I., page 177, as a 
worker on New Zealand Micro-lepidoptera. 
Since Mr. Meyrick has come to Christchurch, and so ably 
taken up the investigation of the New Zealand Micro-lepi- 
doptera, I have abandoned it for the present, and now confine 
myself to the AZacro-lepidoptera. 
I may explain, for the benefit of the uninitiated, that the 
Micro-lepidoptera are the very small moths, the Macro- 
lepidoptera being the larger moths and the butterflies. 
Mr. Meyrick has therefore the greater claim to contributions 
of the smaller moths; but I shall nevertheless be glad to receive 
any that may be sent me, and they shall have my attention. 
Will you kindly make this known in your next publication ?

NOTES AND QUERIES. 
As several communications have been addressed to the 
Editor suggesting the desirability of opening a column in the 
Journal under the above head, it has been resolved to offer 
every facility to those who may desire to ask questions on 
scientific subjects through this medium. As, however, it is ~ 
always much easier to ask than to answer questions, the 
Editor invites the co-operation of specialists throughout the 
colony, and will, as occasion offers, refer to them for replies.
