"The position of the villages will, of course, be useful," he said, "as these are points that would be naturally defended; but what is of most importance is the position of the sand-hills and other eminences, the points at which artillery would command the surrounding country, prepare the way for a force advancing to attack the French, or to check columns advancing against us, the line which the enemy would be most likely to occupy, those by which we might best attack him in front or turn his position."

Edgar looked at the paper in doubt.

"I am afraid, sir, that is beyond me altogether; but if you will tell me where the landing would probably be effected, I could go on from that spot and indicate the various risings and falls of the ground."

"Of course you know the Castle of Aboukir?"

"Certainly, sir. I was on the sand-hills for two days, within half a mile of it, watching the approach of Lord Nelson's fleet and the battle of Aboukir."

"Good!" the general said; "we shall probably land near there."

"The sand-hills rise sharply from the water's edge, and a short distance behind there are several points on which the French would probably place batteries to oppose the landing."

He sketched the line of coast, drew a few lines indicating the trend of the sand-hills, and marked the special eminences. Then step by step he showed the line where the French would probably post themselves, were a successful landing effected, between the heights of Ramleh and the sea, described the country, and, as far as he could, the lay of the land.

"How about water?" the general asked after he had questioned Edgar for more than half an hour.

"There are wells at several points," he said, "but for the most part they are too near the French position for them to be useful to you until you have driven them into the town. There is, however, a well here," and he marked a spot about a mile from the landing-place. "I cannot tell you its exact position. There is a peasant's hut there. He was speaking to us while we were watching the battle, and he told us that he so hated the French that he had filled up his well so that they should not fetch water from it for the garrison of the castle. I have no doubt that I could find the hut, and the man will, I am sure, show you where the well has been, and it will probably take but little trouble to clear it out. The Arabs, however, told me that wherever you find clumps of trees you will be sure to find water at no great depth."
