To me in all this there was something both of wonder and excitement; I knew how in his ordinary work Professor Gregg moved step by step, testing every inch of the way, and never venturing on assertion without proof that was impregnable. Yet I divined more from his glance and the vehemence of his tone than from the spoken word that he had in his every thought the vision of the almost incredible continually with him; and I, who was with some share of imagination no little of a sceptic, offended at a hint of the marvellous, could not help asking myself whether he was cherishing a monomania, and barring out from this one subject all the scientific method of his other life. Yet, with, this image of mystery haunting my thoughts, I surrendered wholly to the charm of the country. Above the faded house on the hillside began the great forest; a long dark line seen from the opposing hills, stretching above the river for many a mile from north to south, and yielding in the north to even wilder country, barren and savage hills, and ragged common land, a territory all strange and unvisited, and more unknown to Englishmen than the very heart of Africa. The space of a couple of steep fields alone separated the house from the wood, and the children were delighted to follow me up the long alleys of undergrowth, between smooth pleached walls of shining beech, to the highest point in the wood, whence one looked on one side across the river and the rise and fall of the country to the great western mountain wall, and on the other, over the surge and dip of the myriad trees of the forest, over level meadows and the shining yellow sea to the faint coast beyond. I used to sit at this point on the warm sunlit turf which marked the track of the Roman Road, while the two children raced about hunting for the whinberries that grew here and there on the banks. Here beneath the deep blue sky and the great clouds rolling, like olden galleons with sails full-bellied, from the sea to the hills, as I listened to the whispered charm of the great and ancient wood, I lived solely for delight, and only remembered strange things when we would return to the house, and find Professor Gregg either shut up in the little room he had made his study, or else pacing the terrace with the look, patient and enthusiastic, of the determined seeker.
