One is conscious of vast trackless wastes of heath and moor, of impenetrable forests and terror-infested bogs; but of the details of plant life there is scarcely a word. In these manuscripts alone do we find what plant life meant to our ancestors, and, as with all primitive nations, their belief in the mystery of herbs is almost past our civilised understanding. Their plant lore, hoary with age, is redolent of a time when the tribes were still wandering on the mainland of Europe, and in these first records of this plant lore there is the breath of mighty forests, of marsh lands and of Nature in her wildest. We are swept back to an epoch when man fought with Nature, wresting from her the land, and when the unseen powers of evil resented this conquest of their domains. To the early Saxons those unseen powers were an everyday reality. A supernatural terror brooded over the trackless heaths, the dark mere pools were inhabited by the water elves. In the wreathing mists and driving storms of snow and hail they saw the uncouth "moor gangers," "the muckle mark steppers who hold the moors," or the stalking fiends of the lonely places, creatures whose baleful eyes shone like flames through the mist. To this day some of our place names in the more remote parts of these islands recall the memory of those evil terrors. In these manuscripts we are again in an atmosphere of eotens and trolls, there are traces of even older terrors, when the first Teuton settlers in Europe struggled with the aborigines who lived in caves, hints as elusive as the phantom heroes in the Saxon poems, and as unforgettable.
