fied up to nearly 350 ft. in height. I liave not seen sufficient 

 undoubtedly neolithic relics — perhaps a dozen polished celts 

 and some four or five barbed " elf- shots " — to know much of 

 the later stone-age men's choice of a dwelling-place. Yet 

 they seem to have occupied the head of the 25-ft. beach, and 

 have perhaps come hither before the close of the surface drift 

 period, or rather in its last closing scenes, and may have seen 

 the land rise to 75 ft. above its present elevation, and also 

 have risen with the old sea to the 25-ft. beach, where they 

 have left numerous interesting remains. Other relics of 

 them are found in peat-filled hollows like the Black Moss. 

 They may also have been crannoge dwellers in lakes long 

 emptied by denudation of some parts of the margins, or 

 drained like Dowalton Loch for agricultural purposes. Here 

 again Mr Wilson has been doing good scientific work. Lately 

 some of the old implements have been found by me on the 

 west coast near the Mull, as well as at Auchneight, Knocken- 

 cule, Barncorkrie, High and Low Clanyard, Cowan, Port- 

 Logan, Mullhill, Ardwell Bay (Stoneykirk), Port o' Spittal, 

 and the shores of Loch Eyan; but they are much more 

 thickly distributed along Luce Bay and in the hollows stretch- 

 ing between the two shores. In many of the implements 

 which Mr Wilson according to prevailing custom designates 

 scrapers and saws, I see very elegantly-finished arrow-heads 

 of a more ancient type by far than the barbed and stalked 

 ones of Neolithic Man. The great distinojuishino- feature of 

 the late glacial arrow-heads, here at least, is their generally 

 flattish under surface, with less or more chipping away from 

 a longitudinal ridge above, or with the ridge unchipped or 

 completely flaked off, but, above all, their elongated lanceo- 

 late form. Variations among them are marked by approaches 

 to the leaf pattern in the more modern ones, or by lateral 

 barbing, or widening or narrowing, or curvation either in or 

 away from a horizontal plane. The transition was from these 

 to leaf arrow-heads, then to winging at the base, and latterly 

 to a footstalk as well as barbs, these last being assuredly 

 neolithic. 



It has so long been asserted firmly that there are no 

 pre-neolithic implements in Scotland, and that their great site
