could not be sent in sacks. They were therefore boiled down 
(three sacks), after being crushed, and produced a rich brown, acrid 
extract amounting to 18 gallons of fluid, which was dispatched in 
two nine-gallon sweet beer barrels, with a hope that some benefit 
may result from the acrid property it contains. A similar extract, 
I find, can be obtained from the dry leaves just as in tobacco, and a 
still stronger one from the shucks of the fruit. 
Should this primary experiment be in any way successful, it will 
be given a fresh trial under more favourable circumstances, the 
extract having been made hurriedly in an old brewing copper in 
twelve hours. 
A Fowl Tick in Western Australia. 
The Acting Director of Agriculture of Western Australia forwarded 
some ticks that were doing considerable harm to poultry in that 
region. 
• The species is probably the American Fowl Tick {Ary as 
americanus, Packard), but owing to being dried up they could not be 
definitely identified. 
An account of this Fowl Tick {Ary as americanus) is given by 
Mr. Froggatt (“Agricultural Gazette,” New South Wales, November, 
1901, Miscellaneous Publications, No. 520).

The Cotton-Boll Worm. 
{Heliothis armiyer , Huebner.) 
Information has been sent to the United States Department of 
Agriculture on the Cotton-Boll Worm {Heliothis armiyer, Huebner) 
in India and Australia in answer to the following communication : — 
“In view of the recent serious injury by the Cotton-Boll Worm 
{Heliothis armiyer, Huebner) in certain sections of the cotton belt of 
the United States, the Division of Entomology of this Department 
has undertaken a renewed investigation of this pest. In this con- 
nection it has appeared desirable to learn as much as possible 
concerning the status of the insect in other countries, particularly 
with reference to its economic importance and of the methods 
employed in its control.
