'Let us leave them to the mercy of the Great Physician; in our case scales may fall from our eyes, and still with imperfect vision we may look up and see men as trees walking, but we must grope on still. Ah, my boy, when in our religious hypochondria whole creeds desert us, and shreds and particles only remain of a fragmentary and doubtful faith, don't let us fight with shadows, which of their very nature elude and fade out of our grasp; let us fall on our knees rather, Cardie, and cry--"Lord, I believe--I will believe; help Thou my unbelief."' Many and many such talks were held, the hours and days slipping away, Mildred meanwhile devoting herself to the precious work of nursing Olive back to convalescence. It was a harder task than even Dr. Heriot expected; slowly, painfully, almost unwillingly, the girl tottered back to life; now and then there were sensible relapses of weakness; prostration, that was almost deathlike, then a faint flicker, followed by a conscious rally, times when they trembled and feared and then hoped again; when the shadowy face and figure filled Mildred with vague alarm, and the blank despondency in the large dark eyes haunted her with a sense of pain. In vain Mildred lavished on her the tenderest caresses; for days there was no answering smile on the pallid face, and yet no invalid could be more submissive. Unresistingly, uncomplainingly, Olive bore the weakness that was at times almost unendurable; obediently she took from their hands the nourishment they gave her; but there seemed no anxiety to shake off her illness; it was as though she submitted to life rather than willed it, nay, as though she received it back with a regret and reluctance that caused even her unselfishness a struggle. Was the cloud returning? Had they been wrong to pray so earnestly for her life? Would she come back to them a sadder and more weary Olive, to tax their forbearance afresh, instead of winning an added love; was she who had been as a little child set in their midst for an example of patient humility, to carry this burden of despondent fear about with her from the dark valley itself? Mildred was secretly trembling over these thoughts; they harassed and oppressed her; she feared lest Richard's new reverence and love for his sister should be impaired when he found the old infirmity still clinging to her; even now the sad look in her eyes somewhat oppressed him. 'Livy, you look sometimes as though you repented getting well,' he said affectionately to her one day, when her languor and depression had been very great. 'Oh no, please don't say so, Cardie,' she returned faintly, but the last trace of colour forsook her face at his words; 'how can--how can you say that, when you know you wanted me?' and as the tears began to flow, Richard, alarmed and perplexed, soothed and comforted her.
