36 THE PROBLEM OF ANTIQUITY OF MAN IN AUSTRALIA 
Warrnambool Museum, but the stone is friable and the impressions 
are almost obliterated ; photographs taken while they were distinct 
were published by Branco (1905) and by Klaatsch (1906). Gregory 
(1904) rejected as man-made both tracks and other impressions. 
The tracks are narrow and are identical in shape with those made 
in snow by kangaroos (Noetling, 1907). There can be little doubt 
that the tracks and other impressions were made by kangaroos, 
not by human beings. 
About 45 years ago OC. C. Brittlebank, Government Plant 
Pathologist, while making geological observations, found a stone 
implement in a bed of gravelly clay 1 ft. 6 in. thick resting on 
Permo-Carboniferous glacial strata and underlying Newer Vol- 
canic lava flows near the junction of Myrniong Creek and the 
Werribee River, about six miles north-west of Bacchus Marsh,

Victoria (Plate I). He presented the specimen to the National 
Museum, but did not publish any record of it. The implement is 
a wedge-shaped slab of hard slaty rock measuring about 7 inches 
by 6 inches, the narrowest part (4 inches) being at the thicker 
end. One face, somewhat roughened by weathering, is slightly 
concave, and near its centre are indentations made by pounding 
with another stone; the opposite face is slightly convex, rougher, 
and shows no signs of usage. Flakes have been struck off the edges 
of one side and of the thinner end, as if to make a crude chopper.
