That day Katy’s duties, fortunately for her peace of mind, brought her frequently into the vicinity of the doll counter.  Now she hastened to it, in a quiver of excitement, to witness the success of the process.  When the cover was taken off the box, her cheeks crimsoned with indignation and her eyes blazed, as she turned inquiringly to Julia.

“Indeed, Katy, it is none of my doings,” protested the salesgirl; though the result of the experiment was so funny she had not the heart to laugh.  The doll with the beautiful blue buckles on her shoes had now a mop of darky wool, and a face as black as the ace of spades.

Julia’s quick wit at once jumped at the correct conclusion regarding the apparent blunder.  The toy-mender’s two thoughtless apprentices had played a joke upon the little cashgirl.

“It is only the nonsense of those rogues upstairs.  I’ll take the doll back and tell them they must fix it to-night, or I’ll complain of them for their fooling at this busy time,” she announced, energetically; for she noted the twitching around the corners of Katy’s mouth, notwithstanding the child’s brave effort at self-control.

Katy went off partially comforted.

“It’s mean to tease a child in that way,” added Julia, in an audible aside, as she laid the doll on the shelf behind, and wished that the lady to whom she was showing some very handsome dolls would finish her choice, so that she might get a free minute to run up to the mending room again.  But the interest of the customer had been awakened by the little drama enacted before her.

“What is the matter?” she inquired, cordially.

Julia looked disconcerted; but the lady had such a sweet and noble face, and her manner was so winning, that the girl found herself telling briefly not only the history of Katy’s doll, but of Katy and Ellie too.  It was not a waste of time either; for while she talked the purchaser made one or two additional selections, and then, after giving directions concerning them, passed on.

“Do you know who that was?” asked Katy, rushing up as the lady turned into another aisle of the store.

“Yes:  Mrs. M——­, of 34th Street.  Of course she left her address for the parcels,” replied Julia.

“It’s my Rose-lady, as I call her,—­don’t you remember the one who gave me the pretty flower?” cried the child.

“Why, so it is!” rejoined Julia.  “Well, she’s a lovely lady certainly.  She happened to ask what the trouble was about the doll; and was so interested I couldn’t help telling how you had saved and planned to get it for Ellie, and all about it.”

“Mercy! did you?” answered the child, in confusion.  “My, but you’re the talker, Julia!  What would the likes of her care to hear about that!”

The store kept open till half-past eleven Christmas Eve; but at length the last customer was gone, and the employees were allowed to choose their presents.  Katy skipped around with joy when the doll was put into her arms.  After a moment, however, Julia whisked it away again, and sent it to be packed in a box.  The box proved to be large and clumsy, but this was accounted for upon the plea of haste.
