Recent Excavations at Stonehenge. 



so that at any future time the depth at which any of the objects 

 were found can be accurately referred to, no matter what changes 

 occur in the ground level. It was found to be 1 foot 5 inches 

 below the bench mark and hence 337*4 above the sea level. 



The position of the objects found was determined by means of a 

 registering frame divided into 6 and 12 inch, and a vertical rod 

 divided into 6 inch spaces. 



The frame and rod are shown in Fig. 1.

Fig. 1. Registering frame and vertical rod. 



The frame, it will be seen, consists of two longitudinal and two 

 transverse planks of deal. 



The longitudinal and transverse pieces are pierced with holes 

 at intervals tb allow them to be adjusted to suit excavations of 

 different areas. They were held in position by pins passed through 

 the holes. 



The long sides are marked at intervals of one foot by letters, 

 each 1 foot length having its distinctive letter. The transverse 

 pieces are similarly divided and marked.
