Nor did we confine our work to the farms near our hiding-place. In the course of his wanderings among his flock, the minister would, now and then, hear of a farm more remote that needed our care, and many a night we walked for miles before we reached the fields where our self-appointed tasks lay. I felt, as Hector did, that in this service we were doing something to help the Cause of the Covenant. And as honest work ever offers to a man the best antidote to sorrow, my heart began to be filled with a great contentment. Mary was lost to me. That thought and the sense of desolation which it provoked was ever before me, but my labours for the persecuted were some token of the love I had borne her and I knew that she would understand. Sometimes, in the darkness, when my back ached beyond endurance as I bent over some unaccustomed task, I would cease for a moment to feel for that little bit of metal lying over my heart that was all that remained of the ring I had given her. And its touch would give me courage and my weariness would disappear. Hector, I discovered, was a master of all the arts of agriculture. No task seemed too heavy for him, and never have I seen a man so proficient at shearing sheep or with such a subtle way of pacifying a querulous dog. Dogs, indeed, were one of the dangers that beset us, for more than once we spent the night at work on a farm which was in the occupation of the soldiery. If the farm dog had but given the alarm, we might have found ourselves surrounded and shot on the instant, or compelled to flee for our lives. But no dog ever barked at Hector. There was some indefinable understanding between him and the faithful creatures. A startled collie would raise its head and thrust forward its snout as though about to alarm the night, but, at a whisper from Hector, it would steal up to him and rub its head and shoulders in comradeship against his legs. This sympathy between himself and the dogs made for our safety, and there was something else which helped. Most of the troopers were creatures of the grossest superstition, thrilled with an uncanny dread of warlocks, witches, and all the evil spirits of the night. Their bloody deeds by day filled their nights with ghostly terrors, and more than once I have known them desert a farm--upon which they had descended to devour its substance like the locusts--headlong and in fear when they found that the "brownies" had been at work in the fields by night. To them it had become a place uncanny, and they would hastily take their departure, to the no small joy of the farmer’s wife and her little children. To the children a visit of the "brownies" was a thing to be hailed with delight and shy amazement.
