I wrote up my journal to-day, and am in good health. My spirits are a little soured, nay, exasperated into activity by these constant troubles. It is very hot now. I have hit upon a happy contrivance for keeping out the sun from my tent. I lay my carpet on the sandy floor of my tent, and with my table and the frame of my bed I make a wooden covering over. On the top I place my mattress and thick blankets, I then lay myself down underneath; and am perfectly protected from the sun above, whilst the cool breeze enters at the bottom of the tent. There is, then, not a person in the caravan who suffers so little from the heat as I do, I recommend the plan to travellers. These last four days we have made immense progress towards Aheer--I mean, its inhabited districts. Wednesday 12-1/2 hours 31 miles. Thursday 13 " 32-1/2 " Friday 14 " 35 " Friday night to Saturday morning 9 " 22-1/2 " ------- At 2-1/2 miles an hour 121 miles. Sometimes, however, the camels went at least three miles an hour. We have come, indeed, about 130 miles, and nearly all south; which has brought us so much more within the influence of the climate of Soudan. On the third day, at noon, the granite region disappeared, and we have now sandstone again. Some of our servants have begun to feel uneasy, and are becoming troublesome, in consequence of these constant alarms of Haghar. To do the free blacks justice, they behave well. Yusuf is getting out of temper, and somewhat changed in manner. He is annoyed at seeing me not place so much confidence in him as at first; I have reason to be dissatisfied with his carelessness. Mahommed of Tunis is a good servant, but at times impertinent.
