The rains appear during the wet season to fall very heavily and constantly in North-Western Australia, and though a good supply of these is an advantage to an occupied country, well provided with roads, it is a great cause of trouble to first explorers who have to find a ford over every stream, and a passage across every swamp, and who often run the risk of getting into a perfectly impassable region. Of this sort, alike differing from the barren sandstone and the volcanic fertile country, was a third track through which Captain Grey endeavoured to pass. A vast extent of land lying low and level near the banks of the river Glenelg,[5] and well fitted, if properly drained, for the abundant growth of useful and valuable produce, was found, during the rainy season, to be in the state of a foul marsh, overgrown with vegetation, choking up the fresh water so as to cause a flood ankle-deep; and this marshy ground, being divided by deep muddy ditches, and occasionally overflown by the river, offered, as may be supposed, no small hindrances to the progress of the travellers. In some places it was quite impossible, from the thickly-timbered character of its banks, to approach the main stream; in others they appeared to be almost entirely surrounded by sluggish waters, of which they knew neither the depth nor the nature of their banks. Elsewhere, unable to cross some deep stream, the explorers were driven miles out of their way, and sometimes even in their tents, the water stood to the depth of two or three inches. On one occasion, when the party was almost surrounded by swamps, their loaded ponies sank nearly up to the shoulders in a bog, whichever way they attempted to move, and from this spot they had two miles to travel before they could reach the nearest rising ground. The river Glenelg was at this time overflowing its banks, and, to the natural alarm of men wandering in its rich valley, drift-wood, reeds, grass, &c. were seen lodged in the trees above their heads, fifteen feet beyond the present level of the water, affording a proof of what floods in that country _had been_, and, of course, _might be_ again. However, this very soil in so warm a climate, only about sixteen degrees south of the equator, would be admirably fitted for the cultivation of rice, which needs abundance of moisture. But little do the peaceful inhabitants of a cultivated country, well drained, and provided with bridges and good roads, think of the risk and hardships undergone by the first explorers of a new land, however great its capabilities, and whatever may be its natural advantages. [5] This river must not be confounded with another of the same name in South Australia.
