is here, as elsewhere, N.W. and S.E. for the longer axis, and the 
sharpest end towards the west. 
4. In the policy of Cameron House a boulder of gneiss, 6 J x 5 x 5 
feet, is lying on gravel, and at a height of about 55 feet above the 
lake, or 80 feet above the sea. Its longer axis is N.W. and S.E. 
5. There is a hill called “ Caer-man,” about 3 miles to the S. W. 
of the south end of Loch Lomond. Its height above the sea is 720 
feet. From its top, a good view is obtained of Helensburgh and 
Greenock towards the S.W. 
The rocks on the top of this hill are a coarse porphyry. Huge 
fragments have been strewed in great abundance down the side of 
the hill sloping eastward, and especially S.E. The unmoved rocks 
present their west surfaces rounded and smooth, their east surfaces 
angular and rough. 
On examining the separate blocks where heaped upon one another, 
it was apparent that the uppermost blocks, to obtain their positions, 
must have been projected on the others from the westward.

Linton . — On the farm of Drylaw, a greenstone boulder, 5| x 3J 
x 3 feet, was found in cutting a deep trench through the boulder clay. 
The jST.W. end was the most rounded. The longer diameter was 
N.N.W. (magn). There were i |0 s trice on the top, but there were 
horizontal striae on the two sides fronting the H.E. and the S.W. 
These two sides met in an angle towards the N.W. If a current had 
flowed from W. by N. the current would divide at the angle; and if 
ice floated in the current, the striae on the two sides might have been 
produced by hard pebbles from the westward pushed against them. 
The smoothing and striation on the north were greater than on the 
south side. Close to the boulder there were pebbles of limestone 
shale, sandstone, and coal, which most probably came from the west- 
ward. The nearest greenstone rocks are on the Garlton hills, situated 
about 6 miles to W. by N. The boulder, therefore, most probably 
came from these hills. 
About half a mile to south, there are rocks (viz., in Linton vil- 
lage, and in a railway cutting to the west), presenting smoothings 
and stria tions, made by some agent moving over them from W. 
by N.
