It took much time and patience to bring order out of this confusion. But Katy knew that Aunt Izzie would be up by and by, and she dared not stop till all was done. By the time it was finished, she was very tired. Going down stairs, she met Elsie coming up with a slate in her hand, which, as soon as she saw Katy, she put behind her.
"You mustn't look," she said, "it's my letter to Cousin Helen. Nobody but me knows the secret. It's all written, and I'm going to send it to the office. See—there's a stamp on it;" and she exhibited a corner of the slate. Sure enough, there was a stamp stuck on the frame.
"You little goose!" said Katy, impatiently, "you can't send that to the post-office. Here, give me the slate. I'll copy what you've written on paper, and Papa'll give you an envelope."
"No, no," cried Elsie, struggling, "you mustn't! You'll see what I've said and Cousin Helen said I wasn't to tell. It's a secret. Let go of my slate, I say! I'll tell Cousin Helen what a mean girl you are, and then she won't love you a bit."
"There, then, take your old slate!" said Katy, giving her a vindictive push. Elsie slipped, screamed, caught at the banisters, missed them, and rolling over and over, fell with a thump on the hall floor.
It wasn't much of a fall, only half-a-dozen steps, but the bump was a hard one, and Elsie roared as if she had been half killed. Aunt Izzie and Mary came rushing to the spot.
"Katy—pushed—me," sobbed Elsie. "She wanted me to tell her my secret, and I wouldn't. She's a bad, naughty girl!"
"Well, Katy Carr, I should think you'd be ashamed of yourself," said Aunt Izzie, "wreaking your temper on your poor little sister! I think your Cousin Helen will be surprised when she hears this. There, there, Elsie! Don't cry any more, dear. Come up stairs with me. I'll put on some arnica, and Katy sha'n't hurt you again."
So they went up stairs. Katy, left below, felt very miserable: repentant, defiant, discontented, and sulky all at once. She knew in her heart that she had not meant to hurt Elsie, but was thoroughly ashamed of that push; but Aunt Izzie's hint about telling Cousin Helen, had made her too angry to allow of her confessing this to herself or anybody else.
"I don't care!" she murmured, choking back her tears. "Elsie is a real cry-baby, anyway. And Aunt Izzie always takes her part. Just because I told the little silly not to go and send a great heavy slate to the post-office!"
