_Tuesday, April 11th._—The men did not want to leave the well before the P.M. Had to force them. Almost a revolt. Quite a little misunderstanding has sprung up between our friends. Left at 7:30. Traversed a high plain. Fearfully hot. Camped at 11:30. Were treated to a whirlwind of sand. Tried to amuse ourselves at revolver practice to pass away the hours of intense mid-day heat. Started again about 5 P.M. Passed on from plain to plain between bare, black, rocky mountains. Camped at 10:30 in a sandy spot. Had dinner at 12:30 A.M. We are all tired, but in pretty good spirits. _Wednesday, April 12th._—Started at 7:30. Marched till 11:30. Found a few bare thorn bushes and tried to spread our blankets over them in such a way as to afford us a little shade till the caravan with the tents came up. Even the poor little donkey that the guide rides, and our camels, also, asked to share our scanty shade with us. The thermometer stands at 111° in the shade. Cooked an egg in the sand. Started again at 5 P.M. The latter part of the evening journey I make on foot. The rest of the crowd is generally used up. At last, Midani is able to go no further, and, on his account, we are obliged to halt for the night. The camel drivers protest, saying that the water is all gone, and that we shall suffer before we reach the next well. We make a personal inspection and find that there are five skins half full. One of these is given to the drivers, one to the cooks, and three for our own use are placed at the foot of my cot for safe keeping. Went to bed at 1:30 A.M. _Thursday, April 13th._—Up at 4 A.M. Started at 5:45. We have had a long tramp over plain after plain, on and on to the mountains and through a high mountain pass till, at length, we have reached the wells of Arieb. It is very hot. Crowds of camels, cattle and donkeys are around the principal well, all drinking. The water is not very good, but we drink it and try to imagine that it is. The tents are up, and after a good bath we tumble into our cots, glad of a little rest.
