While Robert thus once more for a season stood behind the cherub with the flaming sword, Ericson was teaching two stiff-necked youths in a dreary house in the midst of one of the moors of Caithness. One day he had a slight attack of blood-spitting, and welcomed it as a sign from what heaven there might be beyond the grave. He had not received the consolation of Miss St. John without, although unconsciously, leaving something in her mind in return. No human being has ever been allowed to occupy the position of a pure benefactor. The receiver has his turn, and becomes the giver. From her talk with Ericson, and even more from the influence of his sad holy doubt, a fresh touch of the actinism of the solar truth fell upon the living seed in her heart, and her life burst forth afresh, began to bud in new questions that needed answers, and new prayers that sought them. But she never dreamed that Robert was capable of sympathy with such thoughts and feelings: he was but a boy. Nor in power of dealing with truth was he at all on the same level with her, for however poor he might have considered her theories, she had led a life hitherto, had passed through sorrow without bitterness, had done her duty without pride, had hoped without conceit of favour, had, as she believed, heard the voice of God saying, 'This is the way.' Hence she was not afraid when the mists of prejudice began to rise from around her path, and reveal a country very different from what she had fancied it. She was soon able to perceive that it was far more lovely and full of righteousness and peace than she had supposed. But this anticipates; only I shall have less occasion to speak of Miss St. John by the time she has come into this purer air of the uphill road. Robert was happier than he ever could have expected to be in his grandmother's house. She treated him like an honoured guest, let him do as he would, and go where he pleased. Betty kept the gable-room in the best of order for him, and, pattern of housemaids, dusted his table without disturbing his papers. For he began to have papers; nor were they occupied only with the mathematics to which he was now giving his chief attention, preparing, with the occasional help of Mr. Innes, for his second session. He had fits of wandering, though; visited all the old places; spent a week or two more than once at Bodyfauld; rode Mr. Lammie's half-broke filly; revelled in the glories of the summer once more; went out to tea occasionally, or supped with the school-master; and, except going to church on Sunday, which was a weariness to every inch of flesh upon his bones, enjoyed everything.
