(. Eucalyptus acmenioides) and Yellow Bloodwood (Euca- 
lyptus trachyphloia) are dominant. Where the soil is of 
an open sandy nature on low hills, Sugar Gum (Ango- 
phora lanoeoiata) is common. On the flats Swamp 
Mahogany ( Tristania suaveolens) is found in numbers 
with tea tree ( Melaleuca leucadendron) var. viridiflora 
fringing the water holes. Among the smaller trees, Acacia 
falcata (not common), A. c-onferta , A. complanata, and 
Tristania conferta, numerous dogwood (Jacksonia 
scoparia) in flower on the higher parts ; on the lower 
ground Melaleuca leucadendron var. minor was very 
numerous, as was Acacia Cunning hamii. Grass Trees 
(X author rhaea minor) were very numerous on some parts 
of the area traversed. On the creek banks, hundreds of 
Melastoma malabathricum are in full bloom; with these 
were associated a number of Dianella revoluta, also in 
flower. Later in the season many species of under shrubs 
and herbs are to be found in flower. The principal grass 
is Themeda australis , with Eremochloa maculata, Aristida 
queenslandica , A. ramosa , Entolasia spp. Cymbogon 
refractus, Arundinella sp and Imperata arundinacea, 
the last two being very common on the flats. 
On the ridges and rougher ranges the Stringy Bark 
forest is replaced by an association of Red Tronbark 
(. Eucalyptus siderophloia) ; in most parts the run-off is 
rapid, the period of moisture deficiency longer, with less 
leaching of plant food, and in places the ancient (Palaeo- 
zic) slates, porphyries, tuffs, and thick beds of volcanic 
ash have been exposed. All these have helped in the pro- 
duction of a ground flora, which differs in many ways 
from that recorded from the Stringybark, Pultenaea 
ternata and Acacia amblygona , from almost pure patches 
of up to an acre or more. Oxylobium aciculiferum is al- 
most as numerous. A golden wattle, Acacia fimbriata , 
is found in the more open spots with plants of Monotoca 
scoparia and Daviesia ulicina to represent the more scat- 
tered species. Acacia falcata forms a wattle scrub in places 
20 feet high, with brush box ( Tristania conferta) as an 
associate as we approach the outskirts of the rain forest. 
We. prefer' to strike the rough country crossing over the 
Divide which separates the Baffle Creek catchment area 
from that of Mullet Creek, and which is an offshoot of the 
Watalgan Range, rising up to over 1,000 feet in altitude 
a mile south of where we descend to Walsh’s Creek, our 
destination (that is, as far as we can ride) being where 
this creek enters the scrub on a rather picturesque flat, 
where one can watch the struggle for existence between
