Kangaroos, which abounded particularly along the scrub, had formed numerous paths through the high grass to the water's edge.

I now directed my course to the W.N.W., but soon found myself checked by a dyke or wall of basaltic lava, composed of boulders and tabular blocks heaped over each other in wild confusion, and covered by scrub; it stretched from N.W.to S.E.

I travelled round its edge to the southward, after having made a vain attempt to cross it.

The outlines of the stream ran out in low heads into the flat table land, and there we met occasionally with springs and chains of water-holes which united lower down into a water-course, which, after following alternately the outline of the scrub, and turning into the stream of lava, became lost among its loose rocks.

The lava was very cellular; the basalt of the table land solid.
