From a hill near the mouth of this glen it could be seen that this creek ran into a much larger one, in the course of three or four miles.  There also appeared a kind of valley in which the new creek lay; it and its valley seemed to run east and west.  On arrival at this new feature the following morning, I found the channel very broad and sandy-bedded, with fine vigorous eucalyptus timber growing upon either bank.  I was at once certain that this new feature was the upper portion of the Ashburton River, which enters the sea upon the west coast.  It has always been supposed to be the largest river in Western Australia.  No traveller had ever reached so high a point up it previously; of course its flow was to the west.  Only a small stream of water was running down its bed, caused no doubt by the late rains.  The valley down which it runs is so confined and stony, that no sufficient areas of country suitable for occupation can be had on it, in this neighbourhood.  Its course was nearly from the east, and we followed along its banks.  In the immediate neighbourhood there was very fine grass and herbage.  I struck it in latitude 24 degrees 5’, and longitude 118 degrees 30’.  A branch creek joins it from the north-east at nine miles.  I encamped upon it for the first time on the 11th of May.  In our progress up this river—­I use the term in its Australian sense, for at this portion the Ashburton might be termed a dry river only—­we found a slight stream of water trickling along its bed.  The banks are low, the bed is broad.  We had to travel mainly in the sandy bed, as this proved the best travelling ground in general, the valley being both narrow and stony.  On the second day it appeared that the only water that ran down the bed came from another creek, which joined from the south; above that spot the Ashburton channel was quite dry, although we occasionally found small ponds of water in the sand here and there.  At night, on the 12th, there was none where we camped; the river still ran nearly east and west.  That hideous and objectionable vegetation, the Triodia irritans, or spinifex, was prevalent even in places where the waters sometimes flowed.  We have had plenty of this enemy ever since we left Mount Gould.  No natives were seen, or appear to exist here.  A few strips of good country occur occasionally on the banks of the river, but not in areas of sufficient extent to be of any use for occupation.  Neither man, beast, bird, nor fish was to be seen, only an odd and apparently starving crow was occasionally heard.  As we travelled farther up the river, there was even less appearance of rain having fallen; but the grass and herbage is green and fresh, and it may be it was visited by rains previously.  There are excellent acacia and other leguminous bushes for the camels.
