necessary to propitiate by special prayers. Not only the stars of heaven, but springs of water and the simple wayside herbs, were to them directly associated with unseen beings. There are times when one is reminded forcibly of that worship of Demeter, "nearer to the Earth which some have thought they could discern behind the definitely national mythology of Homer." They believed that the sick could be cured by conjurations and charms, as firmly as we believe to-day in curing them by suggestion--is there any real difference between these methods?--and when one reads the charms which they used in administering their herbs one cannot help wondering whether these were handed down traditionally from the Sumerians, those ancient inhabitants of Mesopotamia who five thousand years before Christ used charms for curing the sick which have now been partially deciphered from the cuneiform inscriptions. But before studying the plant lore therein contained, it may be as well to take a preliminary survey of the four most important manuscripts. The oldest Saxon book dealing with the virtues of herbs which we possess is the _Leech Book of Bald_, dating from about A.D. 900-950. Unlike some other MS. herbals of which only a few tattered pages remain, this perfect specimen of Saxon work has nothing fragile about it. The vellum is as strong and in as good condition as when it first lay clean and untouched under the hand of the scribe--Cild by name--who penned it with such skill and loving care. One's imagination runs riot when one handles this beautiful book, now over a thousand years old, and wonders who were its successive owners and how it has survived the wars and other destructive agencies through all these centuries. But we only know that, at least for a time, it was sheltered in that most romantic of all English monasteries, Glastonbury.[3] This Saxon manuscript has a dignity which is unique, for it is the oldest existing leech book written in the vernacular. In a lecture delivered before the Royal College of Physicians in 1903, Dr. J. F. Payne commented on the remarkable fact that the Anglo-Saxons had a much wider knowledge of herbs than the doctors of Salerno, the oldest school of medicine and oldest university in Europe. "No treatise," he said, "of the School of Salerno contemporaneous with the _Leech Book of Bald_ is known, so that the Anglo-Saxons had the credit of priority. Their Leech Book was the first medical treatise written in Western Europe which can be said to belong to modern history, that is, which was produced after the decadence and decline of the classical medicine, which belongs to ancient history.... It seems fair to regard it [the Leech Book], in a sense, as the embryo of modern English medicine, and at all events the earliest medical treatise produced by any of the modern nations of Europe." The Anglo-Saxons created a vernacular literature to which the continental nations at
