We arrived early in camp, and on the following day we moved sixteen miles farther up stream, and camped under a tamarind-tree by the side of the river.  No European had ever been farther than our last camp, Delladilla, and that spot had only been visited by Johann Schmidt and Florian.  In the previous year, my aggageers had sabred some of the Base at this very camping-place; they accordingly requested me to keep a vigilant watch during the night, as they would be very likely to attack us in revenge, unless they had been scared by the rifles and by the size of our party.  They advised me not to remain long in this spot, as it would be very dangerous for my wife to be left almost alone during the day, when we were hunting, and that the Base would be certain to espy us from the mountains, and would most probably attack and carry her off when they were assured of our departure.  She was not very nervous about this, but she immediately called the dragoman, Mahomet, who knew the use of a gun, and she asked him if he would stand by her in case they were attacked in my absence; the faithful servant replied, “Mahomet fight the Base?  No, Missus; Mahomet not fight; if the Base come, Missus fight; Mahomet run away; Mahomet not come all the way from Cairo to get him killed by black fellers; Mahomet will run—­Inshallah!” (Please God.)

This frank avowal of his military tactics was very reassuring.  There was a high hill of basalt, something resembling a pyramid, within a quarter of a mile of us; I accordingly ordered some of my men every day to ascend this look-out station, and I resolved to burn the high grass at once, so as to destroy all cover for the concealment of an enemy.  That evening I very nearly burned our camp; I had several times ordered the men to clear away the dry grass for about thirty yards from our resting-place; this they had neglected to obey.  We had been joined a few days before by a party of about a dozen Hamran Arabs, who were hippopotami hunters; thus we mustered very strong, and it would have been the work of about half an hour to have cleared away the grass as I had desired.

The wind was brisk, and blew directly toward our camp, which was backed by the river.  I accordingly took a fire-stick, and I told my people to look sharp, as they would not clear away the grass.  I walked to the foot of the basalt hill, and fired the grass in several places.  In an instant the wind swept the flame and smoke toward the camp.  All was confusion; the Arabs had piled the camel-saddles and all their corn and effects in the high grass about twenty yards from the tent; there was no time to remove all these things; therefore, unless they could clear away the grass so as to stop the fire before it should reach the spot, they would be punished for their laziness by losing their property.  The fire traveled quicker than I had expected, and, by the time I had hastened to the tent, I found the entire party working frantically; the Arabs were slashing down the grass with their
