"We will give them one more day," Jim Tucker said. "I vote we stop here to-night, then have a good drink in the morning and then start back again, keeping along the canal here until we are close to the lake; then we will have another good drink and start out and walk along the lake until we find a boat, then we will hide away somewhere near it and cross after it gets dark." It was agreed that this plan should be carried out, and after a good night's rest they started again next morning. They kept down by the foot of the bank of the canal, and followed it until they saw the lake stretching away on the left, then they went up and had another drink. "Hurrah!" Arthur Hill exclaimed, as he picked up a broken earthenware pot, which had apparently been thrown out by some passing boat; "this will hold a quart of water. That will give us a drink each to-night." As they walked they had heard the heavy guns still booming over the sea, and felt by no means certain that the troops had yet landed. However, they determined not to put off their expedition across the lake if they could find a boat. Carrying their jar of water carefully with them, they struck across to the lake and followed it as before, keeping a careful look-out for boats. They had proceeded about two miles along its edge, when they saw the stern of a boat projecting beyond the rushes that fringed the water's edge, and pushing more rapidly forward they came upon a beaten path through the reeds, and following this came upon a low flat boat, very roughly constructed. "It is not much of a craft," Jim Tucker said; "but it will do for us capitally. Now, we have only to lie down and take things quietly until dark. I fancy it is about three o'clock in the afternoon now by the sun." They lay down among a clump of bushes a short distance from the lake, and as soon as the sun had set went back to the boat again. They had already made another meal, and had finished their maize and water. They stood by the boat waiting until it should become perfectly dark, and looking across the tranquil sheet of water at the distant town, over which the smoke still hung heavily, and as the sky darkened flashes of fire could be seen. They were at last just going to get on board when they heard an exclamation of surprise behind them. Looking round they saw two natives, who had evidently come down with the intention of going out in their boat. CHAPTER XIII. AMONG FRIENDS. THE astonishment of the two natives at seeing, as they supposed, three women standing with their boat, was no less than that of the boys at being thus suddenly surprised. Suspecting no harm, however, they at once moved forward, asking in Egyptian, "What are you doing here with our boat?" "Down with them, boys?" Jim Tucker exclaimed, and at once threw himself upon one of the boatmen, while Jack and Arthur instantly sprang upon the other. Wholly unprepared for the attack, the men were thrown down almost without resistance.
