All studies of this kind must begin from the standpoint of a definite culture area, and I have chosen our own country for the purpose of this inquiry. This will make the illustrations more interesting to the English reader; but it must be borne in mind that the same process could be repeated for other areas if my estimate of the position is even tolerably accurate. For the purpose of this estimate it was necessary, in the first place, to show how pure history was intimately related to folklore at many stages, and yet how this relationship had been ignored by both historian and folklorist. The research for this purpose had necessarily to deal with much detail, and to introduce fresh elements of research. There is thus produced a somewhat unequal treatment; for when illustrations have to be worked out at length, because they appear for the first time, the mind is apt to wander from the main point at issue and to become lost in the subordinate issue arising from the working out of the chosen illustration. This, I fear, is inevitable in folklore research, and I can only hope I have overcome some of the difficulties caused thereby in a fairly satisfactory manner. The next stage takes us to a consideration of materials and methods, in order to show the means and definitions which are necessary if folklore research is to be conducted on scientific lines. Not only is it necessary to ascertain the proper position of each item of folklore in the culture area in which it is found, but it is also necessary to ascertain its scientific relationship to other items found in the same area; and I have protested against the too easy attempt to proceed upon the comparative method. Before we can compare we must be certain that we are comparing like quantities. These chapters are preliminary. After this stage we proceed to the principal issues, and the first of these deals with the psychological conditions. It was only necessary to treat of this subject shortly, because the illustrations of it do not need analysis. They are self-contained, and supply their own evidence as to the place they occupy.
