April 7. — Another sleepless night from the intense cold. Upon getting up I put a mark upon the beach to guide the overseer to our camp on his return, then weighed out flour and baked bread for the party, as I found it lasted much better when used stale than fresh. I tried to shoot some pigeons with small gravel, having plenty of powder but no shot. My efforts were, however, in vain, for though I several times knocked them over, and tore feathers out, I killed none. The day being very clear, I ascended the highest sand-hill to obtain a view of what had appeared to us to be a long point of land, stretching to the south-west. It was now clearly recognisable as the high level line of cliffs forming the western boundary of the Great Bight, and I at once knew, that when we left our present position, we could hope for no water for at least 140 or 150 miles beyond.
