ARBOR LOW EXCAVATIONS IN 1901 AND T902. 51 



18 inches (45-7 cm.), followed by a stiff clayey-mould to the 

 bottom. The hard sides of the ditch and causeway were 

 exposed. 



Section 2, 10 feet (3-05 m.) wide, was next commenced on 

 the north-western side at a distance of 16 feet (4"88 m.) to the 

 west of the north-by-west causeway. (See section line E-F on 

 plan.) The greatest depth of the ditch in this cutting was 

 found to be only z\ feet (76-2 cm.) ; and nothing being found 

 here, the re-excavation of the ditch was continued* from this 

 point in the direction of the causeway, the solid sides of which 

 were found. Stone relics were fairly numerous in this part, 

 called " Ditch Extension, Section 2." The average depth of 

 the ditch, the bottom of which was very uneven, was 3 feet 

 (91-4 cm.) here. 



Amongst the relics found here were six flakest of black flint, 

 of fine quality, weathered white to a considerable depth, mostly 

 of exceptionally large size; they lay together, at a depth of 

 2-7 feet (82 cm.) from the surface, on a ledge on the solid 

 side of the causeway (No. 17, plan, and section line N-K). 

 These flakes must have been placed by hand on the ledge and 

 forgotten, eventually becoming buried in the silting, or perhaps 

 purposely concealed ; they could not have come by accident 

 into the position in which they were found. The flakes are 

 of considerable size and weight. Though of irregular form, 

 their edges are still sharp and undamaged. Mr. Henry 

 Balfour has suggested that they might possibly have been 

 intended to be used as digging tools. They are figured in 

 fig. 7, page 65, § scale linear. 



There were also found in the Ditch Extension of Section 2, 

 the flint implements numbered 5, 8, 10, 11, 13, 14 and 15 nn 

 plate V., and similarly marked on the plan. 



In this cutting a small oval-shaped hole in the limestone 

 floor was found, filled with a stiff clayey mould, but no relics 

 were discovered in it. The only animal remain here was a 

 tooth of sheep, depth 0-7 foot (21 cm.)

t Two of these flakes have since been found to join.
