At 7.30 a.m. resumed our journey on the same course as yesterday, and at
9.15 came on an extensive flat covered with salicornia, which formed the
margin of an immense salt marsh or dry lake, extending to the north-east
and south-west to the horizon, but narrowing to about three miles at the
point we came to it. It was decided to attempt crossing at this place,
and, after travelling for an hour across the salicornia flat, reached the
bare salt marsh. This at first seemed firm; but, after half-a-mile, the
hard crust of salt and gypsum, which formed the surface, gave way and
three of the horses were bogged almost at the same time. After a long
ineffectual struggle to extricate themselves they were quite exhausted,
and we waded through the mud to the opposite shore, a distance of
half-a-mile, and cut some small trees, and with them, combined with
tether ropes and saddle-bags, formed two hurdles or platforms twelve feet
long and two feet wide. These with much difficulty were taken to the
horses, and by placing them alternately in front of each animal, worked
them over the soft mud, and after six hours of severe exertion succeeded
in reaching the firm ground. The hard salt crust, though apparently
strong, having once been broken, its edges gave way like thin ice. After
reaching the ground, which was dry enough to bear the weight of the
horses, we had to travel about three miles through soft dust of white
gypsum, in which we sank from one to two feet, but at length reached a
large granite rock, at the foot of which there was a little grass and on
the rock some small pools of rainwater.
