n take it up to the house." He gave Mary V a mysterious
look and went into the room where he slept.

Mary V followed him as far as the door, and saw Curley take two letters
from under his pillow. Her heart gave a jump at that, and it began to
beat very fast when he turned and put them into her hand with another
mysterious look. She thanked him and hurried out on the porch and
straight to her pet ledge. Her dad's letter could wait.

On the ledge she sat down, and with fingers that shook she tore open, an
envelope addressed to "Miss Mary V. Selmer, care of Curley." It had been
sealed very tightly, as though it contained secrets. Which it did.

Mary V read that letter through from beginning to end five times before
she left the ledge. It was not exactly a love letter, either, though Mary
V squeezed it between her palms and then kissed it before she put it away
out of sight. After that she cried lonesomely and stared away into that

"_Dear Mary V_," (Johnny had written) "I'm not going to tell anybody

because the two don't go together worth a cent, and I have sure found
that out, and so has your dad, I guess.

"Well, I can't ask you to wait till I have made good, because that
wouldn't be square, but I can say that when I have made good I am
coming back, and then if some other fellow has got the start of me he
will sure have to go some to keep his start. Because I am going to have
you some day, if I have anything to say about it. I'll teach you to
fly, and we will sure part the clouds like foam and all the rest of it.
