A step or two farther I was overtaken by an old man in a brown nightcap, clear-eyed, weather-beaten, with a faint excited smile. A little girl followed him, driving two sheep and a goat; but she kept in our wake, while the old man walked beside me and talked about the morning and the valley. It was not much past six; and for healthy people who have slept enough, that is an hour of expansion and of open and trustful talk.

‘Connaissez-vous le Seigneur?’ he said at length.

I asked him what Seigneur he meant; but he only repeated the question with more emphasis and a look in his eyes denoting hope and interest.

‘Ah,’ said I, pointing upwards, ‘I understand you now. Yes, I know Him; He is the best of acquaintances.’

The old man said he was delighted. ‘Hold,’ he added, striking his bosom; ‘it makes me happy here.’ There were a few who knew the Lord in these valleys, he went on to tell me; not many, but a few. ‘Many are called,’ he quoted, ‘and few chosen.’

‘My father,’ said I, ‘it is not easy to say who know the Lord; and it is none of our business. Protestants and Catholics, and even those who worship stones, may know Him and be known by Him; for He has made all.’

I did not know I was so good a preacher.

The old man assured me he thought as I did, and repeated his expressions of pleasure at meeting me. ‘We are so few,’ he said. ‘They call us Moravians here; but down in the Department of Gard, where there are also a good number, they are called Derbists, after an English pastor.’

I began to understand that I was figuring, in questionable taste, as a member of some sect to me unknown; but I was more pleased with the pleasure of my companion than embarrassed by my own equivocal position. Indeed, I can see no dishonesty in not avowing a difference; and especially in these high matters, where we have all a sufficient assurance that, whoever may be in the wrong, we ourselves are not completely in the right. The truth is much talked about; but this old man in a brown nightcap showed himself so simple, sweet, and friendly, that I am not unwilling to profess myself his convert. He was, as a matter of fact, a Plymouth Brother. Of what that involves in the way of doctrine I have no idea nor the time to inform myself; but I know right well that we are all embarked upon a troublesome world, the children of one Father, striving in many essential points to do and to become the same. And although it was somewhat in a mistake that he shook hands with me so often and showed himself so ready to receive my words, that was a mistake of the truth-finding sort. For charity begins blindfold; and only through a series of similar misapprehensions rises at length into a settled principle of love and patience, and a firm belief in all our fellow-men. If I deceived this good old man, in the like manner I would willingly go on to deceive others. And if ever at length, out of our separate and sad ways, we should all come together into one common house, I have a hope, to which I cling dearly, that my mountain Plymouth Brother will hasten to shake hands with me again.

Thus, talking like Christian and Faithful by the way, he and I came down upon a hamlet by the Tarn. It was but a humble place, called La Vernède, with less than a dozen houses, and a Protestant chapel on a knoll. Here he dwelt; and here, at the inn, I ordered my breakfast. The inn was kept by an agreeable young man, a stone-breaker on the road, and his sister, a pretty and engaging girl. The village schoolmaster dropped in to speak with the stranger. And these were all Protestants—a fact which pleased me more than I should have expected; and, what pleased me still more, they seemed all upright and simple people. The Plymouth Brother hung round me with a sort of yearning interest, and returned at least thrice to make sure I was enjoying my meal. His behaviour touched me deeply at the time, and even now moves me in recollection. He feared to intrude, but he would not willingly forego one moment of my society; and he seemed never weary of shaking me by the hand.

There was something in this landscape, smiling although wild, that explained to me the spirit of the Southern Covenanters. Those who took to the hills for conscience’ sake in Scotland had all gloomy and bedevilled thoughts; for once that they received God’s comfort they would be twice engaged with Satan; but the Camisards had only bright and supporting visions. They dealt much more in blood, both given and taken; yet I find no obsession of the Evil One in their records. With a light conscience, they pursued their life in these rough times and circumstances. The soul of Séguier, let us not forget, was like a garden. They knew they were on God’s side, with a knowledge that has no parallel among the Scots; for the Scots, although they might be certain of the cause, could never rest confident of the person.

‘We flew,’ says one old Camisard, ‘when we heard the sound of psalm-singing, we flew as if with wings. We felt within us an animating ardour, a transporting desire. The feeling cannot be expressed in words. It is a thing that must have been experienced to be understood. However weary we might be, we thought no more of our weariness, and grew light so soon as the psalms fell upon our ears.’

The valley of the Tarn and the people whom I met at La Vernède not only explain to me this passage, but the twenty years of suffering which those, who were so stiff and so bloody when once they betook themselves to war, endured with the meekness of children and the constancy of saints and peasants.

Like my mountain Plymouth Brother, he knows the Lord. His religion does not repose upon a choice of logic; it is the poetry of the man’s experience, the philosophy of the history of his life. God, like a great power, like a great shining sun, has appeared to this simple fellow in the course of years, and become the ground and essence of his least reflections; and you may change creeds and dogmas by authority, or proclaim a new religion with the sound of trumpets, if you will; but here is a man who has his own thoughts, and will stubbornly adhere to them in good and evil.

Only one, on the other hand, professed much delight in the idea; and that was my Plymouth Brother, who cried out, when I told him I sometimes preferred sleeping under the stars to a close and noisy ale-house, ‘Now I see that you know the Lord!’
