the low ridges where the soil is derived from andesitic or 
amphibolithic, rock detrital, its place is taken up by bitter 
blue grass, ( Bothriochloa decipiens), a very poor sub- 
stitute for the Kangaroo Grass, with small areas of Bunch 
Spear Grass ( Heteropogon contort us) , and another rather 
tall species, Hyparrhenia filipendula. On the acid soils 
of a rather sandy nature, Paddock Love Grass ( Erayros - 
tis leptostachya) in the open, and Eriachne Armittii, with 
several species of three awned spear grasses in the thickly 
timbered country. On the fiats where a few Blue Gum 
trees ( Eucalyptus tereticornis) are yet left standing, and 
the soil is of a calcarious nature, the native violet, Viola 
hederacea on the drier parts, and Juncus spp. on the 
lower and better moisture holding spots, is striving with 
Paspalum with some degree of success. On the more 
sandy flats where Red Blood wood (Eucalyptus corym- 
bosa) and Swamp Mahogany ( Tristania s uaveolens) are 
the forest dominants, Blady Grass (Tmperata cylindrica 
var. Koenigii) with patches of Barb-wire Grass (Cymbo- 
pogon refractus), and a few tufts of Sporobolus diander, 
are the principal grasses. Banksia int eg ri folia, Grevillea 
Banksii, Casuarina torulosa, Acacia aulacocarpa, and 
Acacia Maideni are also common on these flats. Thei most 
striking contrast, however, is the great differences be- 
tween the ground flora of the roads and the adjoining 
paddock, and that found growing within the confines of 
the railway fences, which has proved a' refuge for many 
species of herbs which could not withstand the altered 
conditions brought about by closer settlement. Within 
these fences, Kangaroo Grass (Theme da australis) grows 
in profusion, and Capillipedium parvif Jorum , and Sorg- 
hum fulvurn are in some parts very common. Among the 
leguminous herbs, Vigna vexillata- and Vigna lateola. 
Glycine foment osa . G. tabacina , Mimosa pudica , Indigo- 
fera hirsute , anrl several others' are all very common here, 
but are seldom seen in the adjoining paddocks. Within 
these fences are also found representatives of species 
found in, the north and west of the State, the seed having 
been introduced by stock trains. 
We now leave the railway and enter on the second 
and last stage of our journey through the State forests, 
which present new features in several ways. The first 
part of our trip was through country which had been 
flooded by andesitic lava in late Tertiary times, and the 
soil and flora reflected in a way its influence. We now 
pass through country where conglomerate (apparently 
Cretaceous Eoceme) contributes most of the soil bulk, 
hence we have a very different association of trees, etc., 
to that already passed through. Yellow Stringy Bark
