The growth of interest in archaeological research, of which our own times afford so many proofs, has the double advantage of assuring recognition of such additions to knowledge as may from time to time be made, and of emphasizing the need to fill the gaps which the increase of knowledge only serves more clearly to define. While it would be unreasonable to look for the solution of most of the outstanding problems of archaeology in the near future, it is evident that a clear conception of the most profitable lines of inquiry is essential to any progress.
