When Mark arrived he proved to be a tall, bright-faced boy of sixteen, overflowing with good spirits, who contrived to get acquainted with all the inmates of the house before twenty-four hours had passed.

He took a lively interest in the tree, and suggested having it in his uncle's study. Then on Christmas Eve the cases could be moved out of the way in the shop, and both rooms be given up to the frolic.

As the Spectacle Man was more than willing, this was decided upon; and as it would give them so much more room, Miss Moore thought she'd like to ask two other young women, who were studying in a business college, and boarded in the same house with her Texas friend. Mark knew two fellows he'd like to have, and his uncle wished to invite a young man who had come once or twice to his Bible class, and who was a stranger in town.

"Perhaps," said Mrs. Morrison, when they were discussing it, "we had better limit our invitations to those who are not likely to have a merry Christmas."

"My young man doesn't look as if he knew the meaning of merry," said Mr. Clark.

"My girls may know its meaning, but they haven't much chance to practise it, in the dingy boarding house," added Miss Moore.

"I am sure Mrs. Gray doesn't have any fun," said Frances, who clung to her idea of asking the old lady.

There couldn't have been found a merrier party in the whole city than that at work in the Spectacle Man's study on Christmas Eve. Mark had brought in a quantity of cedar and mistletoe, and while Mrs. Morrison and Miss Sherwin trimmed the tree, the children and Miss Moore turned the shop into a bower of fragrant green.

Mark was full of mischief, and romped with Frances, and teased Emma until she wished she could crawl under the bookcase as Peterkin did under the same circumstances. The General trotted about in a gale of delight, getting in everybody's way, and was most unwilling to leave the scene of action when his mother came to take him to bed.

Mrs. Bond lifted her hands in dismay at so much work for nothing.
