PRESIDENTIAL ADDRESS. 14t 
South Australia: The mouse visitation extended from 
Hawker in the North, to Millicent in the South-east, and 
from Fowler’s Bay on the West Coast (Eyre’s Peninsula) 
to Pinnaroo in the East. 
(3) Evidence of spread from one district to another. 
New South Wales: The experiences on the Murrumbidgee 
River mentioned under (2) may suggest migration. 
Victoria: The evidence of the mice spreading was shown 
by their appearance first in North-western and later in 
Northern and Southern districts. 
South Australia: There was no evidence of spread. They 
were found 400 miles west of Port Augusta on the East- 
West railway. 
(4) Did the mice multiply in the fields and then wmvade 
the stacks, or mvade both simultaneously ? 
New South Wales: The mice are of migratory habits, and. 
were first noticed in the fields—especially in stubble pad- 
docks. Stacks at stations adjoining stubble paddocks ap- 
pear to have received first attention. Those further re- 
moved were not attacked until later.on. The ploughing of 
the fields seems to have driven them to the wheat stacks. 
Victoria: Where the mice multiplied is unknown. They 
first appeared in the fields, and later in the wheat stacks. 
The absence of the young in wheat stacks shows that they 
did not multiply there. 
South Australia: So far as we know the mice bred in 
the fields, and then invaded the stacks. | 
(5)Special Breeding Times, (a) in the Fields, (b) in the 
Stacks. 
New South Wales: In the early stages of the plague, say 
from April until well on in July, no signs of young mice 
were found in any of the stacks; but from that date on 
nests have been found, although not to any great extent.
