"I tell you what we'll do, Stubbins: it's a game I used to play
when I was young--before Sarah came to live with me. I used to
call it Blind Travel. Whenever I wanted to go on a voyage, and I
couldn't make up my mind where to go, I would take the atlas and
open it with my eyes shut. Next, I'd wave a pencil, still
without looking, and stick it down on whatever page had fallen
open. Then I'd open my eyes and look. It's a very exciting game,
is Blind Travel. Because you have to swear, before you begin,
that you will go to the place the pencil touches, come what way.
Shall we play it?"

"Oh, let's!" I almost yelled. "How thrilling! I hope it's
China--or Borneo--or Bagdad."

And in a moment I had scrambled up the bookcase, dragged the big
atlas from the top shelf and laid it on the table before the
Doctor.

I knew every page in that atlas by heart. How many days and
nights I had lingered over its old faded maps, following the blue
rivers from the mountains to the sea; wondering what the little
towns really looked like, and how wide were the sprawling lakes!
I had had a lot of fun with that atlas, traveling, in my mind,
all over the world. I can see it now: the first page had no map;
it just told you that it was printed in Edinburgh in 1808, and a
whole lot more about the book. The next page was the Solar
System, showing the sun and planets, the stars and the moon. The
third page was the chart of the North and South Poles. Then came
the hemispheres, the oceans, the continents and the countries.
