Noel wasn't anywhere about, and there was a door in the wall.

And it was open; so we went through.
'The bear has hidden himself in these mountain fastnesses,' Oswald said.
'I will draw my good sword and after him.' So I drew the umbrella, which Dora always will bring in case it rains, because Noel gets a cold on the chest at the least thing--and we went on.
The other side of the wall it was a stable yard, all cobble-stones.
There was nobody about--but we could hear a man rubbing down a horse and hissing in the stable; so we crept very quietly past, and Alice whispered-- ''Tis the lair of the Monster Serpent; I hear his deadly hiss! Beware! Courage and despatch!' We went over the stones on tiptoe, and we found another wall with another door in it on the other side.

We went through that too, on tiptoe.

It really was an adventure.

And there we were in a shrubbery, and we saw something white through the trees.
