Isabel looked at him with but partial comprehension; her point of view was more elevated than his, but yet it was limited, like his, to her own side of the question. She looked at his clouded brow and averted face with a woman’s first violent effort to enter into a state of feeling which was the antipodes of her own. Slowly it dawned upon her that it might be as just as her own though so different. She clasped her arms round the slender white stem of a young birch-tree, and leant against it, gazing at her lover with dreamy eyes.

‘Maybe it’s all true,’ she said, slowly, ‘both what I think and what you think, Horace. It will break my heart, but I can bear it if that is best. Go away into the world, and please your own folk—and I’ll wait for you; I’ll wait all my life; I’ll wait years and years. Why should you lose your best days for me? Oh, I see well it is neither just nor right; and me that has so little to give! It’s a sin to keep you here,’ she continued, tears, unthought of, dropping from her eyes. ‘Loch Diarmid comes natural to me, and folk forget—But go, Horace, and think on me sometimes; and my heart will go with you; and if you should ever come back you’ll find me waiting here.’

‘Isabel, this is all folly and nonsense,’ cried young Stapylton. ‘What are you crying about? am I talking of going away? It is all very easy to send a fellow off and make a fuss, or to keep him hanging on, and kicking his heels among this confounded heather. Can’t you do what I want you instead? it’s simple enough. What’s the good of living in Scotland if you can’t get married how you please? If I were to go away I might never come back. They’d keep fast hold of me at home, or they’d pack me off somewhere out of reach; and you would change, and I might change. Who can undertake what would happen? I don’t believe in comings back. I should find you Mrs. Somebody or other with half a dozen—— Hallo, where are you going now?’

‘I’m going home,’ said Isabel, drying her tears indignantly. ‘It’s late, and I cannot enter into such questions. I am not one to change; but, Mr. Stapylton, if that’s your way of thinking it’s far best it should all come to an end. I don’t want to be married. I will never leave my sister. If you will have an answer yes or no, there’s your answer. Never, never, if she should live a dozen years!—and God send she may live a dozen years, and a dozen more to that!’ cried Isabel with a sob. ‘My Margaret, that never has a thought but for me! And to bid me run away and shame the house, and break her heart—and to call it love!’ said the girl, with an outburst of tears.

She had come back to the birch and leant her pretty head upon the graceful young tree, which waved its tender branches over her with a curious sympathetic resemblance to her own drooping form, while her lover drew near her slowly, his heart melting, though his temper was still ruffled. He was going to her to take her in his arms, to whisper his final arguments, to woo her with his breath on her cheek. At such a moment it did not occur to the young man to look around him, to guard against interruption; and, perhaps, in the soft twilight he could scarcely have perceived the lonely personage who was winding with a noiseless step among the heather, full of her own thoughts.

The dew was falling among the slender birches, and on the heather and gorse—the wild gale underfoot filled the air with sweetness, and with this soft perfume came the soft stir of silence, the breath of the great quiet, which gave a musical tone to the atmosphere. The shadows were falling over the loch and the hills; points of view that had been visible one moment were invisible the next; and all at once, up in the blue heavens, stars were revealing themselves, here and there one, like lamps among the clouds. A night to tempt anyone to linger in the open air, in the quiet, sweet, soft, darkling, humid twilight, full of the silences and splendours of nature, and unawares moved by some brooding of God. The other figure which, veiled by night, and by abstracting thought, was wandering devious on those hills, thinking little of where she went or whom she met, was in her way a better embodiment of the sentiment of the night than were the agitated lovers. It was Ailie Macfarlane come out to roam at eventide like Isaac. She had a shawl over her head after the primitive fashion common to all nations, her head veiled because of the angels. Sometimes she stumbled among the heather, not remarking whither her foot strayed. The darkling world in which those solemn hills stood up each folded in his twilight mantle, with stars about his head and a forehead wet with dew, was full of God to the inspired maiden. Her eyes were moist, like all the earth, with dew. Her mind was full, not of thought but of a quiet consciousness. The poetry that was love to Isabel was to Ailie, God. She was in His presence, His great eyes were upon her, at any moment she might hear His voice calling to her, as Adam heard it in the cool of the garden. As she strayed upon the hills alone with that great trembling, thrilling Nature which was conscious, too, of His presence, the Lord had strayed communing with His Father. He had passed the whole night there, as His servant was not able to do. He had gone down the darkling slopes and set his foot, unaware of the restrictions of nature, upon the gleaming silvery waters below as she could have done on the loch had her faith been but strong enough. ‘More faith! more faith!’ she murmured to herself as she went, ‘O Lord, increase my faith.’ Her young soul was burning within her with the cravings which Margaret Diarmid had divined; not soft submission to Him that rules Heaven and earth, but eager anticipations, restless energy, a heart full of passion. Joan of Arc might so have strayed on her southern moors; though it was from the yoke of Satan that Ailie longed to deliver her people—from wickedness, and disease, and misery. Why should not she? Had not the Lord promised whatsoever ye ask? Had not He granted to all eyes authentic wonders? Was His arm shortened that it could not save? or was there anything wanted but faith, more faith?

The sound of voices roused her from her abstraction, first to a sudden flush of annoyance, and then, as she perceived the two figures before her, to a warm thrill of zeal for their conversion. ‘The Lord has delivered them into my hand,’ the enthusiast said to herself. Their backs were turned to her, and their minds so much occupied that even the crackle of the heather under her foot did not betray her approach. She was close by their side, laying a sudden hand upon the shoulder of each before they were even aware of her presence.

‘What do ye here?’ said Ailie, rising as it seemed to them like a ghost out of the darkness. The two sprang apart and gazed at the intruder, but Ailie was too much absorbed by her office to heed their looks. ‘Isabel Diarmid,’ she repeated with solemnity, ‘what do you here?’

‘I was doing nothing,’ said Isabel, startled back into self-possession: ‘I might say what were you doing coming upon folk like a ghost?’

‘If ye mean a spirit,’ said Ailie, ‘it’s like that I wish to come. What is this poor body that we should let it thrall us? If I had faith I might fly upon angel’s wings: but oh! I’m feared it was not to serve the Lord that you two came here. Na, stand apart, and let me speak. Can ye see a’ this world round about ye, and no feel that you’re immortal? Isabel, the Lord would fain have ye to be His servant—and you too, young man.’
