70 ARBOR LOW EXCAVATIONS IN I9OI AND 1902. 



appears to have been preserved.* Sir John also mentions the 

 rinding of a rare form of circular knifef at Arbor Low in 1867, 

 fig. 11, formerly in the Lucas collection; and in addition he 

 figures a finely-chipped flint knife, or knife-dagger, J fig. 13, 

 nearly 6 inches (15 cm.) long, found at Arbor Low in June, 

 1865 (Lucas Collection). Jewitt has engraved the same 

 implement full size,§ and this and the circular knife, fig. ir, 

 as well as the smaller knife of the same kind, fig. 12, 4-7 cm. 

 in diameter, are now|| in the British Museum.H Unfortunately, 

 there appear to be no records of the discovery of these imple- 

 ments, and as their gisement is unknown, they assist very 

 slightly in the determination of the actual period of the 

 erection of Arbor Low.** 



Arbor Low is of such precise age as the barbed arrow-head 

 may be assigned tu v it having been found on the bottom of 

 the ' deepest portion of the fosse. This form, being usually 

 recognized as a late development in Neolithic flint working, 

 points to the probability of the construction of the fosse and 

 vallum not being assigned to a date earlier than the Late 

 Neolithic period, although, judging from various " finds " of 

 Neolithic arrow-heads of barbed form, they may perhaps have 

 been in use, in some districts, about the middle of the 

 Neolithic period. However, there were no indications that 

 this arrow-head might have reached its position at a date long 

 subsequent to the formation of the fosse. On the other hand, 

 it is well known that the " tanged and barbed " type of arrow- 

 head is very frequently found associated with Bronze Age 

 finds. The existence of stone implements to the exclusion of 

 bronze does not necessarily establish a Neolithic age for a
