Greenlaw . — Marchmont (Sir Hugh H. Campbell). About 930 feet 
above sea, a blue whinstone boulder 9 J x 5 x 4J feet, with 
faint striae on top, parallel with longer axis. Original position 
of boulder slightly changed before being seen. Thisbouldermust 
have come from westward. Rocks in situ Old Red. District not

Hutton . — Boulder of whinstone about 12J tons found in clay of 
brickwork. Longer axis W. N.W. Sharpest end towards that 
direction. Probably from Hardens Hill, west of Dunse, 10

Buteshire. 
Big Cumbrae. — Rev. Mr Lytteil, Kilmarnock, pointed out to Con- 
vener many boulders of mica-schist on many parts of island. 
Rocks of island are Old Red. Largest boulder seen is near 
north end of island, at Balloch Martin, 12 x 6 x 3 feet. But 
as much more probably below ground. Longer axis N.N.E. 
Lies in a trough or valley running N.N.E. May have been 
floated through this valley from northward. 
Little Cumbrae. — Rev. Mr Lytteil conducted Convener to highest 
part of island, north of Old Tower, 400 feet above sea. Rocks 
(claystone trap) here smoothed by some agent passing over from 
N. by W. Found several boulders of conglomerate and Old Red; 
none of mica-schist. Largest about 5 feet square, and rests 
on trap rock, by so small a basis that it may once have rocked. 
Known by name of “ Bell Stane.” Mr Lytteil supposes name 
derived from “Beltane” fires lighted here in Pagan times. 
Close to this stone, another smaller conglomerate "boulder, with 
cup on it, apparently artificial, 4 inches diameter and £ inch 
deep. Height above sea, 190 feet. Situated about 2 miles 
N.W. of old castle on east shore. 
No old red or conglomerate rocks in island. Nearest are 
along shore at Rothesay, about 20 miles across sea to N.W.
