Reference generally may be made to an article on the Classification of Burins or Gravers by Mr. Miles C. Burkitt, M.A., p. 306, Vol. III. of the Proceedings. The object of this article is to illus-trate Gravers from the Microlithic flint sites in West Yorkshire. Specimens have indeed been found in past years, but it is only recently that they have received recognition. And it is hoped that they may help to solve the problem of the age of this industry.

At present there is no clear evidence to dissociate any of the implements here illustrated from the well known microlithic industry of the Pennine Chain. There is, however, some reason to believe that most, but not all, of the Gravers were made during the earlier period of the local industry; whilst the beaked graver-like tools, absent at first, undoubtedly continued to its later stages. Also that gravers associated with tools of La Madeleine type may be established, stratigraphically below the pygmy series.
