GLACIAL BEDS—VICTORIA. 357 
to ascertaining the exact nature and other boundaries of this area, 
no description of it occurring in Mr, Howitt’s paper. The glacial 
area is situated a mile west of the township of Toolleen, 16 miles 
north of Heathcote; it is about 7 miles north of the glacial beds 
on the Wild Duck Creek, Derrinal, mapped and described by Mr. 
E. J. Dunn, F.G.8.* It lies at the north junction of the parishes 
of Crosbie and Weston, and penetrates into the south-west corner of 
the parish of Muskerry. It is irregular in shape, and covers, 
perhaps, a square mile in area, 
The bed-rock of the locality is Lower Silurian, consisting mainly 
of sandstone. These are overlain to the north and west of the 
glacial area by beds of Pliocene age. 
As compared with the neighbouring glacial area of Derrinal, 
that of Toolleen is disappointing. A careful search failed to 
reveal anything in situ which could be classed as glacial conglom- 
erate ; but the presence of erratics, striated, flattened, and grooved 
stones testify to the former presence of a glacial bed. The erratics 
are mostly of granite ; but there are frequent blocks—rounded 
and flattened—of quartzite quite foreign to the district. The 
granites are of two kinds, both ternary, but one has a reddish 
felspar, the other a pink felspar with rather a larger percentage 
of quartz in its composition. They bear no resemblance to any 
granite in Victoria with which I am acquainted ; but are similar 
in type to certain granite erratics found in the glacial beds of both 
Derrinal and Coimaidai. The largest boulder is partly buried in 
the ground ; the mass protruding stands about 1 ft. high with a 
length of 3 ft. 6 in. and a breadth of 1 ft. 10 in.; none of the 
quartzite boulders have a volume greater than 1 cubic foot. 
Certain of the quartzites are apparently identical with those found 
in the Derrinal area. Striated stones were difficult to find; but 
some well-marked ones were secured. One is apparently identical 
with a striated stone collected by me in 1895 from the Derrinal 
area. There are a considerable number of stones lying on the 
surface which, though destitute of groovings, have that flattened 
and rounded appearance so typical of the normal striated stone. 
This collection of erratics, foreign material, striated and flat- 
tened stones, is possibly the remnant of a northern extension of 
the Derrinal glacial area. Denudation has removed the accom- 
panying till matrix until only the harder material has been left. 
There is reason to think that there has been a thinning-out of the 
glacial bed at its northern extremity here as elsewhere in Victoria. 
The boundaries assigned to the Toolleen area are those within 
which material undoubtedly foreign to the locality may be found. 
In this context it may be mentioned that in 1895 I found 
granite erratics on the western fringe of Mount Ida, at a point
