They went to the heath next day, and looked at the pits again. Dick and Joe were talking about the pit-dwellings. Dick said they must have been very damp places to live in; but Joe said no--rabbits and foxes and badgers live in burrows underground, and their fur is always dry. They asked Uncle John’s opinion. He said that he thought in very wet weather the huts would be damp, because the rain would soak in through the roof. But as the village was on the top of the hill, no water would lie about the ground; and, anyway, the men probably dug trenches to carry off the water down the hill. David said he thought the huts must have been very small; he wondered how the people managed to live in them. “Yes,” said Uncle John, “they must have been small. But you see, the people who lived in them had no furniture, and they did not mind crowding. It is very likely, too, that they did not lie down full-length when they went to sleep. There was no room for that in the winter huts. They slept sitting, with their hands clasped over their feet and their chins on their knees. We should not find this a comfortable position to sleep in; but it was the way they were used to. And besides, if a man had tried lying at full length in one of these huts, he would soon have found his toes in the fire. “Before the people learned how to build huts they lived in caves. Why was it better to live in huts than in caves?” None of the boys could think of the answer, so Uncle John said:--“If a man could find a cave that was roomy and dry, it would be a pleasanter place to live in than a dug-out hut with a leaky roof. But if he wanted to live in a cave, he would have to go where the cave was; though if he could build a hut, he might live wherever he pleased. In the whole of a countryside there might not be more than two or three caves fit to live in, so that relations and friends could not live near to each other. But once men had learned to build huts, whole families could live together, and, what is more, they could build a wall or a stockade round the huts, as we have read. There is safety in numbers too, and in many ways it was much more comfortable for them than living scattered over the country in caves.”
