But the Doctor only shook his head. He did not like to think of himself as one of the foolish things of this earth, even though by so doing he might have a better hope of confounding the audacious strength of Rob Glen. But he pondered much upon the subject, and polished up his weapons in private, going through many an argument in his own mind, which was more successful, and preparing snares and pitfalls for the young heretic. He had patronized Rob when Rob was orthodox, but he respected him now as he had never done before.

“I think I will preach my sermon on the fig-tree next Sabbath morning,” he said to his wife after tea. “I think that will stagger him, if anything can.”

“Well, Doctor,” Mrs. Burnside replied, “it will always be a pleasure to hear it; but I fear Robert Glen is one of those whose ears are made heavy, that they cannot hear.”

The Doctor shook his head again, out of respect to the Scriptures; but he was not so hopeless. Perhaps he believed in his sermon on the fig-tree more than his wife did, and he felt that to gain back the young man who had baffled him would be indeed a crown of glory. He spent an hour in his study that night looking up other sermons which specially suited the case. It gave him an interest in his sermons which he had not felt since Sir Claude gave up coming to the parish church, and seceded to the Episcopal chapel in St. Rule’s. That had been a distressing event to the good Doctor, but he had got over it, and now providence had been kind enough to send him a young unbeliever to convince. Perhaps the good folks of the Kirkton and the parish generally would have heard of this looking up of the old discourses with some apprehension; but the Doctor wrote a new introduction to the sermon on the fig-tree, and that was some little gain at least.

Rob left his pastor with less respectfulness than the good Doctor felt for him. After running the gauntlet of the professors, and receiving all the attention he had received as the representative of honest doubt, it is not to be supposed that Dr. Burnside could impress him much, and he took up a great deal of time with his feeble argumentations. When, however, the Minister invited him to come to the Manse to tea, Rob made a very pretty speech about his mother. “She has been very kind to me, though I know I have disappointed her,” he said, “and I must not leave her alone. I don’t think I can leave her alone.”

“That’s the finest thing you’ve said, Robert,” said the Doctor. “I see your heart is right, although your head is all wrong;” and with this they parted, and the good man came in to look over his sermons. As for Rob, he hurried home to collect some sketch-books for Margaret’s benefit, and would not share his mother’s tea, notwithstanding his pretty speech. But it was astonishing how tolerant Mrs. Glen had grown. She shook her head, but she did not insist upon the bread-and-butter.

“I’ll have something ready for your supper if you havena time now,” she said; and entreated him to take the block with to-day’s drawing, which she thought might be offered “in a present” to the young lady.

“Not that, mother,” said Rob, “not till it is finished.”

“Finished!” she said, with a disdain which was complimentary; “what would you have? You canna mend it. It’s just the Kirkton itsel’.”

And she would have liked him to put on his best black coat when he went to meet Miss Margaret, and the tall hat he wore on Sundays. “When you have good claes, why should ye no wear them? She should see that you ken the fashion and can keep the fashion with the best—as my poor purse will feel when the bill comes in,” she added, with a sigh. But at last Rob managed to escape in his ordinary garments, and with the sketches he had chosen. After the events of the day, which had been a kind of crisis in his career, Rob’s mind was full of a pleasant excitement; all things seemed once more to promise well for him—if only this little lady of romance would keep her promise. Would she come again? or had he been flattering himself, supposing a greater interest in her mind than really existed, or a greater freedom in her movements? He lingered about for some time, watching the sun as it lighted up the west, and began to paint the sky with crimson and purple; and as he watched it, Rob was natural enough and innocent enough to forget most other things. Who could attempt to put that sky upon paper? There was all the fervor of first love in his enthusiasm for art, and as he pondered what color could give some feeble idea of such a sky, he thought no more of Margaret. What impossible combination could do it? And if it was done, who would believe in it? He looked at the growing glory with that despair of the artist which is in itself a worship. Rob was not an artist to speak of, yet he had something of the “feeling” which makes one, and all the enthusiasm of a beginner just able to make some expression of his delight in the beauty round him; and there is no one who sees that beauty so clearly, and all the unimaginable glories of the atmosphere, the clouds and shadows, the wonderful varieties of color of which our northern heaven is capable, as the artist, however humble. He was absorbed in this consideration, wondering how to do it, wondering if he ever could succeed in catching that tone of visionary light, that touch of green amidst the blue—or whether he would not be condemned as an impostor if he tried, when suddenly his book of sketches was softly drawn out of his hand. Looking round with a start, he saw Margaret by his side. She had stolen upon him ere he was aware, and her laugh at having taken him by surprise changed into her habitual sudden blush as she caught his eye.
