The Milkman Reef. 
Five hundred yards west of the Excelsior reef is the Milkman reef. 
Some shafts have been sunk along its course, the deepest about 250 feet. 
The strike of the reef is N. 5 deg. W., dip 80 deg. E. The quartz is 
8 inches thick. The length of the workings is 250 feet.

THE SERPENTINE AREA, WELLINGTON RIVER, 
GIPPSLAND. 
By E. J. Dunn , Director , Geological Survey. 
Glenmaggie is about 200 feet above sea-level, and the rocks consist of 
Ordovician sandstone and slate beds. The road to Mount Wellington crosses 
the hills northward from Glenmaggie. for several miles, and then follows 
the Macallister River on the west bank and crosses it about 12' miles from 
the township. Between Glenmaggie and the river the higher ground is 
covered by an older basaltic flow, and the soil resulting from its decomposi¬ 
tion is heavy, black, and fertile. The basalt begins just to the north of 
Glenmaggie and continues on to Mendowra, a distance of 8 miles. The 
road turns off the basalt here, but the basalt flow continues many miles 
to the northward of Mendowra before its source is reached. Men¬ 
dowra is about 1,100 feet above sea-level. Ordovician slate and sand¬ 
stone beds continue northward from Mendowra to- within about 4 miles of 
Glenfalloch. They are covered first by Snowy River porphyries, &c., 
and then by red sandstones and conglomerates of Devonian age. The 
country around Glenfalloch consists of hills rising 1,000 feet and 
more above river level and built up of red sandstones, shales, and con¬ 
glomerates, with pebbles of white quartz as a conspicuous ingredient. 
Glenfalloch is on the east bank oif the Macallister River, 20 miles, from 
Glenmaggie, and about 650 feet above sea-level. The river is a fine stream 
of clear water at this time of the year; it winds through extremely rich 
alluvial flats of which there is a considerable area. The greater portion 
of the hilly country where Devonian rocks prevail affords good grazing. 
Devonian rocks, for the most part highly inclined, continue on past Break¬ 
fast Creek (15 miles from Glenfalloch and 900 feet above sea-level). 
The track after leaving Glenfalloch follows the east bank of the 
Macallister River to where the Wellington River joins it, then follows the 
Wellington River. Half-a-mile below where the Wellington River branches 
the Devonian rocks with Snowy River porphyries give place to Ordovician 
beds. The track then follows the southern branch of the Wellington River, 
called the Dolodrook Creek, and about half-a-mile above the junction is 
Garvey’s hut which was used for camping in. 
Ten chains above the junction of the two branches of the Wellington 
River, Black Soil Creek runs into Dolodrook Creek, and 25 chains up this 
creek the serpentine rock is first met with. The serpentine crosses over a 
ridge and northern slope, and then crosses Dolodrook Creek where Thiele's
