drifts, probably from want of diligent search ; but on the oolitic 

 slopes of our farm we find worked flints and flint cores in 

 abundance, which were doubtless fashioned from flints brought 

 up from the valley at a distance of about a mile and a half there- 

 from. 



Our drawings have been taken from specimens chosen from 

 hundreds of examples, and may therefore be considered as 

 representative examples, which we shall at once describe under 

 the following heads : — 



1. Arrow Reads. 



2. Bird Bolts. 



3. Thumb Scrapers. 



4. Portions of Celts. 



1. AEEOW HEADS. 



These are of various forms ; figures 1 and 2 represent what are 

 called leaf arrow heads, both from their thinness (see sections 1 

 and 2a). They are thin and delicately wrought, and it will be 

 seen that they are indented on their sides probably with the view 

 of tying them on to the shaft of the arrow. Fig 5 is also a broad 

 leafed arrow head, but without being indented. 



Figs 3 and 4 represent the narrow or lanceolate shaped leaf 

 arrow heads ; they are, if possible, more delicately formed than 

 those previously described The section 3a will show their 

 thickness. 



Nos. 6, 7, and 8 are forms of arrow heads of a commoner 

 description. 6 is remarkable for the indentation. 



Fig 12 and 13 are good examples of the fluked arrow heads. 

 The stem enabled them to be fixed to the shaft, while the flukes 

 kept the arrow rankling in the larger bird, or the smaller animal, 

 until they were subdued. 



These are not .common. No. 12 was found at Bradford, bu
