They went out and told the headman that they would protect the treasure when the fighting began. And now they looked about them and were able to see exactly how a first-class worker in flint flakes and notches an arrow-head or the edge of an axe—an advantage which no other person now alive has ever enjoyed. The boys found the weapons most interesting. The arrow-heads were not on arrows such as you shoot from a bow, but on javelins, for throwing from the hand. The chief weapon was a stone fastened to a rather short stick something like the things gentlemen used to carry about and call life-preservers in the days of the garrotters. Then there were long things like spears or lances, with flint knives—horribly sharp—and flint battle-axes. Everyone in the village was so busy that the place was like an ant-heap when you have walked into it by accident. The women were busy and even the children. Quite suddenly all the air seemed to glow and grow red—it was like the sudden opening of a furnace door, such as you may see at Woolwich Arsenal if you ever have the luck to be taken there—and then almost as suddenly it was as though the furnace doors had been shut. For the sun had set, and it was night. The sun had that abrupt way of setting in Egypt eight thousand years ago, and I believe it has never been able to break itself of the habit, and sets in exactly the same manner to the present day. The girl brought the skins of wild deer and led the children to a heap of dry sedge. “My father says they will not attack yet. Sleep!” she said, and it really seemed a good idea. You may think that in the midst of all these dangers the children would not have been able to sleep—but somehow, though they were rather frightened now and then, the feeling was growing in them—deep down and almost hidden away, but still growing—that the Psammead was to be trusted, and that they were really and truly safe. This did not prevent their being quite as much frightened as they could bear to be without being perfectly miserable. “I suppose we’d better go to sleep,” said Robert. “I don’t know what on earth poor old Nurse will do with us out all night; set the police on our tracks, I expect. I only wish they could find us! A dozen policemen would be rather welcome just now. But it’s no use getting into a stew over it,” he added soothingly. “Good night.” And they all fell asleep. They were awakened by long, loud, terrible sounds that seemed to come from everywhere at once—horrible threatening shouts and shrieks and howls that sounded, as Cyril said later, like the voices of men thirsting for their enemies’ blood. “It is the voice of the strange men,” said the girl, coming to them trembling through the dark. “They have attacked the walls, and the thorns have driven them back. My father says they will not try again till daylight. But they are shouting to frighten us. As though we were savages! Dwellers in the swamps!” she cried indignantly.
