"Another soldier died this evening; he was an excellent man, who had been employed at the arsenal at Cairo. His friend and bosom companion was a fellow workman, and he was so grieved at the loss that he declared he should not live beyond a few days. There was no dry ground in which to dig a grave; it was therefore necessary to cut a hole in the base of a white ant-hill, as these Babel-like towers were the only dry spots that rose above the flood. "This death is the sixth within the last few days, exclusive of one boy. I think our black doctor assists them in departing from this life, as they die very suddenly when he attends them. Like Dr. Sangrado, he is very fond of the lancet, which is usually fatal in this climate. We made about half a mile today. "March 26.--Wind fresh from the S.E. The ditch is completely blocked up with vegetation: thus we made only 250 yards. Before us, as usual, is the hopeless sea of high grass, along which is a dark streak which marks the course of the ditch through which we slowly clear a passage. How many days or months we may require to reach the White Nile is a problem. One hundred and fifty men are on the sick list; nearly all of them are fellahs. Upon my own diahbeeah six soldiers out of ten are down with fever, in addition to two of the sailors. I gave them all a shock with the magnetic battery, which appeared to have a wonderful effect; one fellow, who had been groaning with severe pains in his back and limbs, declared that he was instantly relieved. I made a good shot with the Dutchman at a Baleniceps Rex, at a distance of upwards of 200 yards. "There is no rest by night or day for our people, who are preyed upon by clouds of mosquitoes, which attack like bulldogs. "March 27.--All hands hard at work clearing the ditch. Wind S.E.--fresh. The diahbeeah, as usual, leads the way, followed by No. 10 steamer, and the whole fleet in close line. Most of the men suffer from headache; this is owing to the absurd covering, the fez, or tarboosh, which is no protection against the sun. "In the evening I took a small boat, and in forty-one minutes' poling and tugging through the narrow channel, I succeeded in reaching a long narrow lake resembling a river, about 110 yards wide. The mouth of our effluent was, for a wonder, clear from obstruction; I returned with the joyful news to the fleet after sunset. "March 28.--At 7.30 a.m. all hands turned out to clear the channel to the lake; this was about 500 yards long, and the diahbeeah, leading the way, entered the lake at 11.30 a.m. Unfortunately a shallow channel near the entrance prevented the steamers from entering, thus a passage had to be dug in the tough clay beneath them. The wind strong from the south. I am afraid the north wind has deserted us for the season.
