To cultivate its banks within many miles of the bed of the stream (except on some elevated detached spots) will be found impracticable, unless some method be devised of erecting a mound, sufficient to repel the encroachments of a torrent which sometimes rises fifty feet above its ordinary level, inundating the surrounding country in every direction.
The country between the Hawkesbury and Rose Hill is that which I have hitherto spoken of.

When the river is crossed, this prospect soon gives place to a very different one.

The green vales and moderate hills disappear at the distance of about three miles from the river side, and from Knight Hill, and Mount Twiss,* the limits which terminate our researches, nothing but precipices, wilds and deserts, are to be seen.

Even these steeps fail to produce streams.

The difficulty of penetrating this country, joined to the dread of a sudden rise of the Hawkesbury, forbidding all return, has hitherto prevented our reaching Carmarthen mountains.
