64 THE ESSEX NATURALIST. feature of ornithology. This introduction to the folk lore of birds from the Essex point of view is based only on matter which has come to my notice, and it is probable that further searches will add to the stock of information. I know of no better work than Swainson's Provincial Names and Folk Lore of British Birds, and it has been of great service to me in preparing this paper. The amount of lore of which birds are the theme is remarkable, and if other classes of the animal world had been endowed with similar prodigality the dimensions of the whole would reach striking proportions. Thus the amount of available matter has influenced to some extent the plan of construction of this paper. In the first place, I have confined myself to birds on the Essex list (A History of the Birds of Essex, 1929), and in the works I have used I have found 87 Essex birds about which there is folk lore. The tales and romances which the folk of many ages have created around these 87 birds are a different matter, for we have no knowledge that most of them had any association with Essex. An examination of the subject has revealed that a series of aspects, common to a greater or lesser number of birds, exists. It is along these lines that I place before you an Essex basis of the folk lore of birds. I have selected nine of the more general of these controlling influences. They are weather, augury, medicine, talisman, protection, veneration, oath, religion and proverb. These heads do not cover all the knowledge which is available. Examples of each aspect will be introduced and followed by some to illustrate the. stories, etc., which do not fall under the nine chosen heads. The folk lore attributed to a particular species is frequently of a varied nature; as an example I mention the Swallow, which comes under five of the aspects I have adopted, and there is matter relating to this species, which is not thus covered. That weather should play such an important part in the folk lore of birds will surprise no one and particularly ornithologists, for, although weather movements are not fully understood and require much more attention, yet the reaction of birds to altered weather conditions is very evident. In the case of weather the relation of cause and effect is very obvious. The Rook is one of the birds most commonly believed in as a
