"I'll do my best, Master Treffy," said Christie, "I'll do my very best."

And Christie kept his word.


CHAPTER IV.

MABEL'S FIRST LESSON IN ORGAN-GRINDING.

The next day Christie had to go out as usual. Old Treffy seemed no worse than before,—he was able to sit up, and Christie opened the small window before he went out to let a breath of fresh air into the close attic. But there was very little fresh air anywhere that day. The atmosphere was heavy and stifling, and poor Christie's heart felt depressed and weary. He turned, he hardly knew why, to the suburban road, and stopped before the house with the pretty garden. He wanted to see those merry little faces again,—perhaps they would cheer him; he felt so very dull to-day.

Christie was not disappointed this time. He had hardly turned the handle of the organ twice before Mabel and Charlie appeared at the nursery window; and, after satisfying themselves that it really was Christie, their own organ-boy, they ran into the garden, and stood beside him as he played.

"Doesn't he turn it nicely?" whispered Charlie to his sister.

"Yes," said little Mabel; "I wish I had an organ, don't you, Charlie?"

"Shall I ask papa to buy us one?" asked her brother.
