miles beyond Richardson's creek we crossed a small run of water flowing west-north-west, apparently towards it. After passing over similar ground for some miles further and having had another plain on our right, we at length encamped near a large serpentine pond or lake which was broad, deep, and bordered with lofty gum trees. July 18. We continued for five miles along good firm ground on which there was open forest of box and gumtrees; and part of the bold outline of the Grampians appeared to our left. THE WIMMERA. At nine miles we fell in with a flowing stream, the water being deep and nearly as high as the banks. I did not doubt that this was the channel of the waters from the north side of these mountains, and I was convinced that it contained the water of all the streams we had crossed on our way to Mount William, with the exception of Richardson's creek, already crossed by the party where it was flowing to the north-west. The richness of the soil and the verdure near the river, as well as the natural beauty of the scenery could scarcely be surpassed in any country. The banks were in some places open and grassy and shaded by lofty yarra trees, in others mimosa bushes nodded over the eddying stream. Continuing along the right bank in a north-west direction we travelled two miles on a grassy plain; and we then turned towards the river, encamping on its banks in latitude 36 degrees 46 minutes 30 seconds South, longitude 142 degrees 39 minutes 25 seconds East. Magnetic variation 5 degrees 21 minutes 45 seconds East. Some natives being heard on the opposite bank, Piper advanced towards them as cautiously as possible; but he could not prevail on them to come over, although he ascertained that the name of the river was the Wimmera.
