In the gTa.p'h, the line A rej^jresents the actual curve of 
variation in tlie water level at Blue Lake. The line B repre- 
sents the curve showing the cunuilative variations from an 
annual rainfall of 19 inches in the County of Lowan (Victoria). 
The line C (j^laced over A and B) represents a similar curve 
based on the variation from 20^- inches per annum in the 
south-eastern counties of South Australia. 
From the close correlation disclosed by these graphs the 
maximum rise and fall of water level for January may be pro- 
]>hesied at the close of the preceding winter’s rainfall. 
A model of Mount Gambier and the lakes, built to exact 
scale, has been constructed by Dr. Fenner, and a copy of same 
will be among the South Australian exhibits at the Empire 
Exhibition. 
LIST OF NATIVE PLANTS GROWING IN THE RAILWAY 
RESERVE AT MILE END. 
By Ernest H. Ising. 
In an early number of this journal (Vol. I., No. 3, 1918) 
Mr. J. M. Black gave an article on ‘^The Primitive Flora of 
Adelaide” and noted 27 native }Jants growing in and around 
the city at that time. Mr. Black's list includes i)la]its which 
were growing in the little piece of 'natural scrub at Enfield 
which has been preserved hitact. The railway ])roperty at 
Mile End has been etuhosed for a long time and (ptite a number 
of native plants have been fiowei'ing there froin August last. 
Specimens have been colle(ded and notes of the flowering 
period, etc., were taken of 17 s}>ecies oiih^ four of tiiese 
being mentioned by Mr. Black in the above article. Observa- 
tions have been carried out since last August and no doubt the 
list could be augmented during the next 12 months. 
The species marked (B) were those recorded by Mr. Black, 
whose new ‘'Flora of South Australia” has been followed in 
the following arrangement of families. 
_ Graminae. (B). Stipa scabra Lindl. Common spear grass. 
This grass is very plentiful and was fioAvering during October 
and Noveipber. It grows in tufts about 6 inches across and u}) 
to 24 inches in height. Its silvery heads, with long fine awns, 
waving in the breeze give it a characteristic appearance. 
Liliaceae. Bulbine bulbosa (B.Br.) Haw. One plant of 
tills sj)ccies Avas fioAA^ering in October, it is evidently rare now 
on the. ])lains, it usually prefers the hills. Grasses' and Aveeds 
may haAm killed the plants.
