Describe Mr. Tumnus's cave from "The Lion the Witch and the Wardrobe.

The entrance to the cave was concealed by a large boulder, and was described as being a nice place, little but dry, and clean. The inside was carved out of reddish stone, with a carpet on the floor, a fireplace, two little chairs, a dresser and a table. There was also a mantelpiece over the fire, with a painting of Tumnus' father, which hung over it on the wall. In one corner of the cave, there was a door that presumably led to Tumnus' bedroom. There was also a wall with an assortment of books on shelves.
