Now, the Cortrells lived thirty-five miles away from Boston, and were quite poor. The father did not see how he could afford the expense of sending Johnny to Boston yet a while, but hoped to do it in the autumn.

Little Jessie overheard her parents talking on the subject, and made up her mind to try and see what she could do. She thought she could not wait three, four, or five months, to have Johnny cured: it ought to be done at once.

The next day she told her plan to Johnny, and they made their preparations; and one bright morning, when it was school-time, she and Johnny stole out of the house hand in hand, quite unnoticed by any one.

They met a little girl named Jane Anderson; and by her Jessie sent the following letter to her parents:—

Dear Father and Mother,—I didn't ask you, for fear you would say No; but Johnny and I are going to Boston to see Dr. Williamson. I heard all the reasons why you couldn't take Johnny till fall, and I couldn't wait. 'Twon't hurt us to walk this nice spring weather; and I don't think any one will refuse to give a poor blind boy and his sister a place to sleep, or a bowl of bread and milk to eat. We shall ask our road, and we won't get lost. Our Father in heaven will go with us all the way.

Mr. Cortrell was much alarmed. "I must start after them, wife," said he. "Those children on the road to Boston all alone! Jessie is crazy."

But Mrs. Cortrell said, "What if God put it into her heart, John?" And so they concluded to do nothing about it.

Well, the children walked and walked, and now and then they got a drive; and, on the third morning, Jessie led Johnny into Boston over the Brighton road.

They found Dr. Williamson. He received them kindly. He examined Johnny's eyes, and then said to Jessie, "I think there are nine chances in ten that I can cure your brother."

Jessie bounded with joy. The good doctor accommodated them in his own house while the cure was going on; and after not many days he sent the children home in the cars, and, as he left them, placed a sealed envelope in the hand of Jessie.
