And Dick’s uncle took him to the top of the tower and showed him the remains of an open fireplace, in which the men of the tower used to light a beacon fire to give the alarm to people in the villages and towns when enemies were coming.
And outside the tower he showed him part of a deep ditch, and told him that once this ditch went right round the house and was called a moat, only that now it was nearly all filled up with earth and stones. But at one time it was always full of water, so that no one could get at the tower without crossing the moat. And the people in the tower used to let down a bridge, called the drawbridge, because it was drawn up and down by means of chains. So that when they or their friends wanted to go out or come in, the drawbridge used to be let down for them, and pulled up afterwards.
And Dick’s uncle told him that all these things used to be done to make houses safe to live in, because once upon a time long ago there were a great many thieves and robbers in the land, and there were no policemen to keep them in order; also that the people used to fight among themselves a great deal; and his uncle showed him some old pieces of armour, and a helmet and a battle-axe and some swords, such as the knights and men-at-arms used in battle long ago.

The next day they set out for their walk--Dick and his uncle John and a collie and two terriers--and Uncle John said: “We will call for Joe first.”
“No,” said his uncle; “Joe is a boy. He is nine, like you, and he lives in the house with the green gate.”
But Joe said he was afraid he could not come for a walk, because his cousin David had come to spend the holidays with him, and they had made a plan to go fishing. So Uncle John invited David, too, and they all set off together.
After they had gone about a mile along the lane, they came to a heath. It was a large open heath on the top of a hill, looking down a slope into a valley. The slope of the hill was covered with bushes, and there were trees in little groups here and there. The hills beyond were mostly covered with woods, and there was a stream in the valley down below. Uncle John led the way until they came to a flattish place on the hill-side. Then he said:
