On the 21st, I was seized again with illness. The overseer continued to be affected also, and we were quite unable to make the necessary preparations for our journey to the westward, which I fully intended to have commenced to-morrow. For several hours we were in the greatest agony, and could neither lie down, sit up, nor stand, except with extreme pain. Towards the afternoon the violence of the symptoms abated a little, but we were exceedingly weak.
