Olly.

"Yes, two I believe; but they don't get on with Polly very well, so they
live in the kitchen out of the way--"

"I like pussies better than pollies," said Olly gravely.

"Why, what do you know about pollies, old man?"

"Pollies bite, I know they do. There was a polly bited Francis once."

"Well, and pussies scratch," said Milly.

"No, they don't, not if you're nicey to them," said Olly; who was just
then very much in love with a white kitten, and thought there were no
creatures so delightful as pussies.

"Well, suppose you don't make up your mind about Aunt Emma's Polly till
you've seen her," said Mrs. Norton. "Now sit down on the rug there and
let us have a talk."

Down squatted the children on the floor opposite their mother, with
their little heads full of plans and their eyes as bright as sparks.

"I'll take my cart and horse," began Olly; "and my big ball, and my
whistle, and my wheelbarrow, and my spade, and all my books, and the big
scrap-book, and--"

"You can't, Olly," exclaimed Milly. "Nurse could never pack all those
up. There'd be no room for our clothes. You can take your whistle, and
the top, and the picture books, and I can take my dolls. That'll be
quite enough, won't it, mother?"

"Quite enough," said Mrs. Norton. "If it's fine weather you'll see--you
won't want any toys. But now, look here, children," and she held up the
map. "Shall I show you how we are going to get to the mountains?"

"Oh yes," said Milly, "that'll be like my geography lesson--come, Olly.
Now mother'll teach _you_ geography, like Fraeulein does me."

"That's lessons," said Olly, with half a pout, "not fun a bit. It's only
girls like lessons--Boys never do--Jacky doesn't, and Francis doesn't,
and I don't."

"Never mind about it's being lessons, Olly. Come and see if it isn't
interesting," said Mrs. Norton. "Now, Milly, find Willingham."

Willingham was the name of the town where Milly and Oliver lived. It is
a little town in Oxfordshire, and if you look long enough on the map you
_may_ find it, though I won't promise you.

"There it is," said Milly triumphantly, showing it to her mother and
Olly.

"Quite right. Now look here," and Mrs. Norton took a pencil out of her
pocket and drew a little line along the map. "First of all we shall get
into the train and go to a place called--look, Milly."

"Bletchley," said Milly, following where the pencil pointed. "What an
ugly name."

"It's an ugly place," said Mrs
