The series of implements which the writer is describing is the result of seven years' research by Major Moore, of Walton, at the mouth of the river Deben on the Felixstowe side of Bawdsey Ferry.

Major Moore was the first to discover that in the heaped-up shingles which are continually shifting at this spot, many rolled and abraded flints showing human workmanship are included. As in the case of the Larne coast finds in Ireland, most of the flints have a white or creamy-white lustrous surface, though in some examples they are ochreous or even black.

The large majority consist of flakes and spalls, and are the refuse of a prehistoric flint factory, but among them are undoubted tools. To what culture they belong is the riddle, which we can only hope to solve by a better acquaintance with them.
