The 19th was another oppressive hot day, with a northerly wind, and clouds of dust which darkened the air so that we could not see the hills distinctly, although we were close under them. The flies were also incessant in their persecuting attacks. What with flies and dust, and heat and indisposition, I scarcely ever remember to have spent a more disagreeable day in my life. My eyes were swollen and very sore, and altogether I was scarcely able to attend to any thing or employ myself in any profitable way.
