“There wasn’t the house when it was brand-new—the house like it is now, I mean,” said Edred. “I don’t suppose there was any attic with chests in when the castle was new.”

“There couldn’t be, not with all the chests,” said Elfrida; “of course not, because some of the clothes in the chest weren’t made till long after the castle was built. I believe grown-ups can tell what a broken thing was like when it was new. I know they can with bones—mastodons and things. And they made out what Hercules was like out of one foot of him that they found, I believe,” she added hazily.

“I’ve got an idea,” said Edred, “if we could get back to where the castle was all perfect like a model and draw pictures of every part. Then when we found the treasure we should know exactly what to build it up like, shouldn’t we?”

“Yes,” said Elfrida very gently. “We certainly should. But then we should have to know how to draw first, shouldn’t we?”

“Of course we should,” Edred agreed, “but that wouldn’t take long if we really tried. I never do try at school. I don’t like it. But it’s jolly easy. I know that. Burslem mi. always takes the drawing prize, and you know what a duffer he is. We might begin to learn now, don’t you think?”

Elfrida sat down on a fallen stone in the middle of the castle yard, and looked at the intricate wonderful arches and pillars, the crenulated battlements of the towers, the splendid stoutness of the walls, and she sighed.

“Yes,” she said, “let’s begin now——”

“And you’ll have to lend me one of your pencils,” said he, “because I broke mine all to bits trying to get the parlour door open the day you’d got the key in your pocket. Quite a long one it was. You’ll have to lend me a long one, Elf. I can’t draw with those little endy-bits that get inside your hand and prick you with the other end.”

“I don’t mind,” said she, “so long as you don’t put it in your mouth.”

So they got large sheets of writing-paper, and brown calf-bound books for the paper to lie flat on, and they started to draw Arden Castle. And as Elfrida tried to draw everything she knew was there, as well as everything she could see, her drawing soon became almost entirely covered with black-lead.
