Mrs. Blyth’s generous, impulsive nature, and sensitively tempered affection for her adopted child, impelled her to take instant and not very merciful notice of Zack’s unpardonable thoughtlessness. Her face flushed, her dark eyes sparkled, as she turned quickly on her couch towards the fire-place. But, before she could utter a word, Madonna’s hand was on her lips, and Madonna’s eyes were fixed with a terrified, imploring expression on her face. The next instant, the girl’s trembling fingers rapidly signed these words:

“Pray—pray don’t say anything! I would not have you speak to him just now for the world!”

Mrs. Blyth hesitated, and looked towards her husband; but he was away at the other end of the room, amusing himself professionally by casting the drapery of the window-curtains hither and thither into all sorts of picturesque folds. She looked next at Zack. Just at that moment he was turning his muffin and singing louder than ever. The temptation to startle him out of his provoking gaiety by a good sharp reproof was almost too strong to be resisted; but Mrs. Blyth forced herself to resist it, nevertheless, for Madonna’s sake. She did not, however, communicate with the girl, either by signs or writing, until she had settled herself again in her former position; then her fingers expressed these sentences of reply:

“If you promise not to let his thoughtlessness distress you, my love, I promise not to speak to him about it. Do you agree to that bargain? If you do, give me a kiss.”

Madonna only paused to repress a sigh that was just stealing from her, before she gave the required pledge. Her cheeks did not recover their color, nor her lips the smile that had been playing on them earlier in the evening; but she arranged Mrs. Blyth’s pillow even more carefully than usual, before she left the couch, and went away to perform as neatly and prettily as ever, her own little household duty of making the tea.

Zack, entirely unconscious of having given pain to one lady and cause of anger to another, had got on to his second muffin, and had changed his accompanying song from “Rule Britannia” to the “Lass o’ Gowrie,” when the hollow, ringing sound of rapidly-running wheels penetrated into the room from the frosty road outside; advancing nearer and nearer, and then suddenly ceasing opposite Mr. Blyth’s own door.

“Dear me!—surely that’s at our gate,” exclaimed Valentine; “who can be coming to see us so late, on such a cold night as this? And in a carriage, too!”

“It’s a cab, by the rattling of the wheels, and it brings us the ‘Lass o’ Gowrie,’” sang Zack, combining the original text of his song, and the suggestion of a possible visitor, in his concluding words.

“Do leave off singing nonsense out of tune, and let us listen when the door opens,” said Mrs. Blyth, glad to seize the slightest opportunity of administering the smallest reproof to Zack.

“Suppose it should be Mr. Gimble, come to deal at last for that picture of mine that he has talked of buying so long,” exclaimed Valentine.
