And where the walls had been and the painted mummy-case, were tall dark green trees, oaks and ashes, and in between the trees and under them tangled bushes and creeping ivy.

There were beech-trees too, but there was nothing under them but their own dead red drifted leaves, and here and there a delicate green fern-frond.
And there they stood in a circle still holding hands, as though they were playing Ring-o'-Roses or the Mulberry Bush.

Just six people hand in hand in a wood.

That sounds simple, but then you must remember that they did not know WHERE the wood was, and what's more, they didn't know WHEN then wood was.

There was a curious sort of feeling that made the learned gentleman say-- 'Another dream, dear me!' and made the children almost certain that they were in a time a very long while ago.
