The country they passed over consisted of large, level plains, intersected by sand-ridges; but they crossed numerous creeks with more or less water in all of them.

To one of these creeks Sturt gave the name of Strzelecki.
Finally they reached a well-grassed region which greatly cheered them with the prospect of success it held out.

Suddenly they were confronted with a wall of sand; and for nearly twenty miles they toiled over successive ridges.

Fortunately they found both water and grass, but the unexpected check to their brighter anticipations was depressing.

Nor did a walk to the extremity of one of the ridges serve to raise their spirits.
Sturt saw before him what he describes as an immense plain, of a dark purple hue, with a horizon like that of the sea, boundless in the direction in which he wished to proceed.
