The Queensland Naturalist September, 1939 
inga when lie was three, and it was at Thackeringa the 
accident happened that made him a cripple for life. With 
Dr. W. R. Macgillivray he founded the Barrier Field 
Naturalists ’ Club, and was its secretary for 19 years. He 
collected an herbarium of over 5000 sheets mainly devoted 
to the botany of the interior of Australia, and particularly 
rich in Acacia, Eucalyptus and Chenopodiaceae. The herb- 
arium is now held by the Zinc Corporation, a public com- 
pany that has done much to encourage scientific endeav- 
our in Broken Hill and district. He was always willing to 
assist botanical colleagues abroad, and his specimens are 
frequently seen quoted in monographs dealing with Aus- 
tralian xerophytic families. He was very keen on the cul- 
tivation of native plants. To show the esteem in which 
he was held locally, it may be mentioned that the Zinc 
Corporation intend to name one of their parks after him. 
There is an avenue from his grave to the gates in the 
Broken Hill Cemetery, and a double memorial avenue 
two miles long is being planted up. It is also planned to 
have a drinking fountain in the main street outside the 
Technical College. 
His wife was a very keen botanist and gardener, and 
most of the work at Broken Hill was a joint endeavour. It 
is pleasing to note that the Zinc Corporation is making it 
possible for her to carry on some of the work.

WALTER ROLLO PETRIE. 
It is with very sincere regret that we have to record 
the death on May 27th. of Mr. Walter R. Petrie, in his 
sixty-sixth year. 
The elderst son of Mr. Thomas Petrie, he was born in 
the district that now bears the family name. After re- 
ceiving his education at the Ipswich Grammar School, he 
turned his attention to agricultural pursuits on the 
Blackall Range, but later joined the Sub-department of 
Forestry, within the Queensland Department of Lands 
He was stationed at Fraser Island and at Imbil in the 
Mary Valley, where lie was associated with extensive re- 
afforestation schemes. After his retirement from the 
Public Service about eight years ago, lie became interested 
in various horticultural experiments on his own property 
and was a recognised authority on the Queensland Nut 
(Ma cad-ami a tcrnifnlia) .
