Saturday, 1st June, Chain of Ponds. I must rest the horses to-day and to-morrow, for they look very miserable; our longitude is 133 degrees 40 minutes 45 seconds. Before leaving the Ponds I shall try once more to the westward--starting from a point three miles west of my first camp on them. To try from this, for the Gulf of Carpentaria, I believe to be hopeless, for the plain seems to be without end and without water. If I could see the least sign of a hill, or hope of finding water, I would try it; but there is none--if there is a passage it must be to the south of this. Wind variable, with clouds.
