The strata in the above section are believed to be identical with those which are 
seen up Jack’s Creek. n n i a 
About a hundred yards above No. 2 Traverse Station, on Eosella CreeK, a 
dolerite sheet is seen, involving lumps of coal, and probably occupying the position 
a coal-seam. It dips to S. at 15°. i 
Occupying apparently a position above the thick beds of sandstone a o 
referred to is the Havilah Coal-Seam, seen on the left bank of Eosella Creek, w ere e 
paddock fence crosses. The following is the section, which has a slight ip o

Dolerite sheet on top of loft bank. 
Havilah Coal-Seam, burnt by “ white trap ” intruded along bedding, 
and rendered columnar, especially in upper part ... 
(About 200 yards up the creek, the place of the coal is taken up by 
the sheet of dolerite, which steals down into it.) 
Dark and grey shales, with a two-feet bed of soft worthless coal in 
the middle 
Greenish-grey sandstone, with trees. 
Blue-grey shales, with plants, and lenticular seams of coal, and 
calcareous bands, and bands of ironstone nodules (slight dip 
to north-east). 
Tho shales seen in the above section appear to die out up-stream, and a consider- 
able thickness of greenish-grey sandstone takes their pilace. A quarter o ^ 
higher the sandstone is pierced by a 3|-feet dyke of dolerite, running E. 1 
the lower coal-seam is again seen on the left bank. The Havilah Seam is ^ 
“ white traps ” intruded along the bedding, and is rendered columnar, especially in 
upper part. {See Sketch, PI. 52, fig. 3.) , , n r ti, tt r.pr 
The Havilah Coal-Seam is not very far from the uppermost beds ot the Uppei 
or Freshwater Series, as, after dipping to the south-east, the strata in a mile oT 
two begin to rise again in that direction. About a mile above the road ro 
Havilah to Byerwin, where it crosses Eosella Creek, there occur some beds of grey an 
reddish ferruginous sandstones. In these beds marine fossils are numerous an we 
preserved. J?erbpa senilis, Phillips, is specially abundant. Loose blocks ot 
wood, apparently from a higher bed which has been denuded, cover the s e e s. 
reappearance, high up in the Hpper Series, which from its base upward has so tar yield 
nothing but plant-remains, of strata charged witli marine fossils, and these o ^ 
which also occur in the Middle Series, is of the highest importance with reference to 
continuity of the two series. An analogous fact is the appearance of ^ \ 
the Middle Series (even down to near the base, as evidenced by tbe Pelican ree o 
associated with its characteristic marine fossils.
