8 THE EASTERN BOUNDARY STONES The search for the other stones was facilitated by the fact that two of them, viz. : Mark's Stone and the Warren Stone, are entered on the six-inch Ordnance Map. This is to be attributed to the cir- cumstance that these stones are also Parish Boundaries, or have been made use of as such. On July 24th, 1894, we found Mark's Stone (Fig. 6), and knowing from the map where to look for the Warren Stone, we soon discovered that it had been removed. After some inquiry we found the missing stone broken off at the base and lying in a ditch by the side of the field near where it had stood. Fig. 6.—Mark's Stone in Whalebone Lane, one of the Old Boundary Stones ok the Forest of Waltham. The inscriptions on both these stones are quite distinct and legible ; it is almost certain that they have been re-inscribed since 1642, or else they must be newer stones which have been placed on the site of the original ones. In support of the latter hypothesis it may be mentioned that an old and weathered stone, almost completely buried, lies alongside of the present Mark's Stone. This view is also favoured by the fact already recorded that the inscriptions on Richard's Stone and the Navestock Stone have become practically obliterated. The inscrip- tion on the Havering Stone also has almost disappeared. On
